System of Rice Intensification (SRI)

 

 

 Past Scenario of rice cultivation in Thiruvarur district

 

 Thiruvarur district is located at heart of cauvery delta zone and contributing major share in rice production. Productivity during kuruvai season is largely varies due to uncertainty in receipt of canal water from Mettur dam. Even if the water is released from Mettur dam, the water flow does not reach the tail end areas of Thiruvarur district. The canal water is regulated as turn system and thus the water does not reach the entire cultivable area of Thiruvarur district. Hence the area and productivity are greatly influenced by release of Cauvery water and borewells. The new technology popularly known as SRI cultivation is one such innovative and integrated approach well suited in this situation to increase area and productivity during Kuruvai. This technology is very useful for not only increasing the yield with fewer quanta of water, but also to reduce the considerable amount of inputs like seed, labour etc. On the above grounds we decided to popularize the technology to all parts of Thiruvarur district.

 
KVK interventions


State sponsored ICDP-SRI

 

Concerted efforts were made easy through State Government sponsored ICDP programme. Totally 193 demonstrations were successfully conducted during 2005-06 throughout the district for which all the critical inputs were demonstrated on free of cost. Based on the request from the SRI experienced farmers, an Interactive Workshop on SRI cultivation was convened at KVK, Needamangalam in the presence of extension functionaries of both Thiruvarur and Nagapatttinam districts and the scientists, more than 75 SRI farmers participated and got clarified their practical problems on this method.

 

 

Initially SRI technology was assessed at field level in five villages to create impact among the farmers. During 2006 -2007 ten OFT was conducted at five villages to assess optimum spacing and nutrient management in SRI method of rice cultivation. These results are appreciated by the farmers and made them to adopt themselves. Accordingly twenty FLDs were conducted at Amirthavalli, Chettichathiram, Melathirupalakudi, Pulavarnatham, Pandaravadai and Thirumahalamkuruvai during Kuruvai 2007-08 and Kuruvai 2008-09. As a result of demonstration the FLD farmers were completely satisfied and they had taken the job of motivating the other farmers in those villages.

In addition to farmers’ field, we have also laid out SRI method of cultivation as demonstration plot in our KVK farm in all Kuruvai seasons (2005-11) which is compared with the normal method of planting, direct sowing and machine planting with using same variety sown on the same date. So the farmers visiting to our farm could actually realize the benefits this technology as seeing believes.

 
On campus and off campus trainings

 

The KVK has conducted about 28 on campus and 16 off campus trainings on SRI in which more than 1000 farmers and farm women participated. In addition, five on campus trainings were given to SRI farmers on how to raise modified mat nursery for SRI cultivation. Exercise was also made to know how many of them actually cultivated the SRI and the results were encouraging (about 66%). Significant on campus and off campus trainings were conducted up to 2009-2010.

 
Other activities to create awareness on SRI

 

In addition six radio and three TV talks were given to create awareness. Other activities included publication of technical bulletins (3 Nos), film shows (55 Nos), method demonstration on mat nursery preparation and square planting (74 Nos), conducting group meetings, etc.

 
Micro level impact

 

Now the SRI method becomes a profitable and alternate method of rice cultivation in the demonstrated villages during the water scarcity period and more than 90 percent of farmers in Amirthavalli, Chetichathiram, Melathirupalagudi, Pulavarnatham, Pandaravadai, Thirumahalam and Melanagai villages are adopting this technology during Kuruvai season in 2060 ha.They realized the benefits of SRI on saving of 8-10 women labours for planting, 12-16 for weeding, 3-4 irrigations and 15-45 kg of N/ha. It has also been realized by farmers that there is reduction in input costs uptoRs.2000/ha and increased net profit of Rs.10000-11000/ ha. All the farmers were reported that they are highly satisfied with this method of cultivation. The farmers in these villages are very much enthusiastic on realizing the benefit of SRI especially on the production of more productive tillers, lengthy panicle, increased grain weight and characters like non lodging and early harvest.

  
Present status of rice cultivation at district level

 

The area and productivity of rice fluctuate over years due to uncertainty release of Cauvery water and natural calamities. However, rice cultivated under SRI in different seasons resulted in enhanced productivity

The farmer Th.R.Arunkumar, an MBA graduate has owning 30 hectares land with two submersible bore well. He adopted rice – rice –pulses cropping system in 20 hectares and sugarcane in 10 hectares. During summer season, due to water limitation some part of the rice cultivated areas is kept as fallow. Earlier his father was managed the entire farm and cultivated rice crop under conventional method and earned around 12,000 to 15,000/ ha/year. During 2007 onwards, he takes responsibility for the entire farm. He took training about SRI method of rice cultivation at KVK, Needamangaalam during December, 2008 and implemented in his farm in an area of 2 acres. He realized the benefits on labour saving and reduction in input cost from SRI method of rice cultivation. Now he has brought 15 hectares of land under SRI method of rice cultivation. He enjoyed the benefits of SRI on saving of 8 women labours for planting, 10 for weeding, 3-4 irrigations and 25 kg of N/ha. He also realized the fruition of this SRI method of rice cultivation by reduction in input costs up to Rs.4000/ha and increased net profit of Rs.18,000-20,000/ ha. This clearly shows the strength of the technology and dedication of farmers who toiled with his mother earth for great success in the Rice bowl region of Tamil Nadu.

Mechanization in Rice

 

Thiruvarur district is located at heart of Cauvery delta zone with Rice based cropping system. Rice is the major crop cultivated in an area of 1,52,000 ha. The rice cultivation in Thiruvarur district has undergone a series of changes given the unprecedented labour shortage and enhanced labour wages for important crop operations like leveling, nursery preparation, transplanting, weeding and harvesting. The labour scarcity become acute leading to delay in agricultural operations in Thiruvarur district.Hence, to address the above said problems KrishiVigyan Kendra, Thiruvarur is working with the thrust area of “Mechanization in rice cultivation”. KVK, approached the problem through popularization of direct sown drum seeder and machineries for transplanted rice.

 
Direct Drum seeding

 

To step up the profitability in rice cultivation, cost cutting technology and mechanization for labour saving is the only way despite of the productivity aspects. By considering the above issues, KVK Thiruvarur district has initiated to popularize TNAU improved drum seeder in Thiruvarur district from 2007 onwards. So far 15 FLDs have been conducted in 15 ha in 4 villages. Besides, 17 on and off campus trainings were organized to diffuse the importance of drum seeder in rice cultivation.

 
Large Scale Demonstration

 

To create awareness among the farmers extensive method demonstration on direct drum seeding technology was organized at KVK instructional farm on 21.06.08. More than 420 farmers participated and get clarified from the experts.

In addition to above 4 booklets and 3 popular articles have been published. Also 4 radio talks and one TV talk have been given.


Micro Level Impact

 

The impact at the operating villages of KVK namely Poonthalagudi, Periyakottai, Iyampettai, Pulavarnatham, Vettaithidal has been immense. In consequent, more than 360 farmers contacted this Kendra to know the technology and its utilization to different situations. On an average, an amount of Rs.1500 to Rs.2000 is saved from this technology, as it doesn’t need nursery, seedling pulling out and transplanting. Moreover, the farmers can take up sowing with family labour or limited labour in event of peak season. Also farmers has visited the FLDs and attended the training programme and gained knowledge and started drum seeded technology. The impact could be well understood from the data of hiring the drum seeder on day basis from KVK, Thiruvarur as detailed below.

Integrated pest and Disease management in Rice

 

In Thiruvarur district it is grown in 1,52,000 ha. Rice crop is attacked by various pest and diseases starting from nursery to harvest . Rice yield loss due to various insects pests was estimated to be 31.5% . The rice plant is subject to attack by more than 100 species of insects of which 20 of them can cause economic damage. Along with insect pests few diseases causing huge yield loss upto 28%. Realizing this menace, KVK, Needamangalam has identified Integrated Pest and Disease Management as one of the important thrust area of its operation.

 

KVK interventions

 

Interventions are framed to reach the farmers effectively. Since its inception it has organized 6 Front Line Demonstrations and 5 On Farm Testing have been conducted on wide variety of pest and disease problems.

30 Off campus trainings on Integrated pest and disease management were conducted to the farmers on topic such as Integrated Pest and Disease Management in rice to enhance the knowledge of IPDM in rice. Two trainings have been conducted to the extension functionaries to disseminate the knowledge of IPDM throughout the district. Several demonstrations on various IPM tactics were conducted and also exhibitions was arranged to enrich and enlighten the knowledge of IPDM in rice crop. In addition to that frequent field visits and field diagnostics visit have been conducted to diffuse and disseminate the knowledge of latest IPDM tactis to the farmers. Besides, 3 Farm Field School (FFS) on ‘Rice IPM’ was conducted at paruthiyur village (2005-06), Rajapaiyan chavady village (2008-09) and Therkkupattam village(2009-10).

A total of 43 media and paper news were given. Five popular articles, one book and one booklet have been published.

Micro level impact

 

Due to the sustained efforts of KVK, Thiruvarur more than 50 per cent of farmers of the cluster villages where the IPDM has been demonstrated and FFS conducted, adopted one or other principle of IPDM. In Puliancherry alone 55% of farmers did switch over to IPDM strategies. This impact has been observed from the enthusiasm of the farmers of Puliancherry to start a farmers club in their village so that they will get counseling of the KVK scientists on a sustainable basis through the club.

 

Economic impact

 

The economic impact was assessed by partial budgeting of Mr. Sethuraman of Puliancherry village.

 

Technological impact

 

In the year 2009-10, 10 FLDs were conducted in Therkkupattam cluster village, one Farmers Field School was also conducted on Ecofriendly IPM in rice. There were 5 awareness campaigns and two off and on campus trainings in each were conducted on Ecofriendly IPM in rice. There were totally 575 farmers have participated in these Ecofriendly IPM in rice technology spread programmes.

The percentage adoption of these eight Ecofriendly IPM technologies in rice have varied from 96.00 percent of Pseudomonas use and very less adoption of 19.00 percent in LCC based ‘N’ application. Out of 575 farmers, 549 farmers i.e., 96.00 percent of farmers had adopted the use of Pseudomonas. The use of Pheromone traps and egg parasitoid has also found to be very meager i.e., 21 percent each in these two technologies. The non-availability of Pheromone traps and egg parasitoid was the reason for the non-adoption of these two technologies. The overall adoption of Ecofriendly IPM technologies in rice among the farmers was 43.25 percent. The farmers could save 2-3 rounds of pesticide sprays in their fields. This was purely because of the contact of scientists KVK, Needamangalam with the farmers and their continuous inducement to adopt the technologies.

 

 Macro level impact

 

Due to continuous efforts taken by the KVK, Thiruvarur, the farmers of Thiruvarur district adopting important bio inputs such as Pseudomonas, Achook(Acorus calamus) powder and neem oil for the management of pest and disease in paddy. Moreover these three bio inputs available under subsidies from the Department of Agriculture, Thiruvarur district. It is evident that Pseudomonas fluorescens,,ACK10D and neem formulations sold at good quantum.

Precision farming

 

 

   Past agricultural scenario of Thiruvarur district

 

Thiruvarur district located at Cauvery delta region of Tamil Nadu which is most suitable for cultivation of paddy crop because of clayey nature of soil. However the income generated out of the paddy crop is not much satisfactory. The farmers are reluctant to go for cultivation of vegetable because, the farmers has strong mind set towards traditional paddy cultivation. In certain pockets of the area in Thiruvarur district is highly suitable for vegetable cultivation. They are growing vegetables with local varieties during summer season under traditional method of cultivation. But their net income per ha was much less. The technology ‘Precision Framing’ came at that time for their livelihood.

  

   KVK interventions

 

  Precision farming part II plan

 

Technological demonstration on precision farming was implemented in Tiruvarur district during 2007-08 under Part II plan scheme after the great success in Dharmapuri and Krishnagiri districts. In this project, elite and dynamic farmers have been identified based on their interest and involvement in agriculture and allied activities. The Cauvery Delta Farmers owe strong mindset on traditional mono cropping of rice from time immemorial. Hence, farmers exposure visit to Dharmapuri and Krishnagiri districts was made to get acquaintance with the latest technical knowhow from the farmers who already practicing it. We brought the farmers to precision farming project through repeated meetings and trainings both individually and group approach to break their mindset towards scientific farming. Twenty demonstrations were laid out in our district with formidable success despite of the unseasonal and erratic rainfall during the month of December 2007 and February 2008.

 

 NADP Precision Farming 2007-08

 

In this project 20 elite farmers have been selected and trained very well including field exposure visit. Selection of the crop viz., vegetables and sugarcane left to farmer’s choice in a participatory mode. Expertises of KVK Scientists are being extended to them as follow up. First time in this region (CDZ), subsurface drip fertigation for sugarcane was laid out to facilitate for the farm mechanization apart edging over from labour scarcity in agriculture. Out of twenty farmers 14 have grown vegetables and 6 have grown sugarcane under precision farming. Because of successful implementation of precision farming in the rice bowl of Tamil Nadu this KVK has identified as the training centre for nearby seven districts viz., Trichy, Pudukottai, Thanjavur, Thiruvarur, Permbalur, Ariyalur and Nagapattinam. During 2008-09 this KVK has organized 28 No of two days training programme including field exposure visits. In total 1040 farmers of the above districts had undergone training and equipped very well on precision farming technology.

 

NADP Precision Farming 2008-09

 

In this project also, twenty farmers were selected and trained. Out of twenty farmers six have grown vegetables and 14 have grown sugarcane under precision farming. The KVK alone has brought 60 precision farmers under one umbrella of ‘Thiruvarur district precision farmers association’ and continuously giving expertise to make them to get higher and higher income. As part of the scheme, this KVK has organized 12 two days training programme including field exposure visits and trained 347 farmers of Thanjavur,Thiruvarur and Nagapattinam Districts during 2008-09.

 

 NADP Precision Farming 2009-10

 

As part of the scheme, this KVK has to train 1240 farmers of any districts in Tamil Nadu.  During  2010-11, this KVK has organized 6 two days training programme including field exposure visits and trained 100 farmers of Thanjavur, Thiruvarur and Nagapattinam Districts.

Success story

 

Th. N.Saravanan of Melanagai village had earlier grown ragi, groundnut and pulses. After the KVK intervention, he is growing vegeatbles like Brinjal, Bhendi, Chillies and Gourds under precision farming. The farmer has owning 3 hectares land with single submersible bore well. He cultivated 1 hectare during summer and the 2 hectares during monsoon period with Ragi, Groundnut and Pulses in the existing cropping system. From this he earned around 20,000 to 25,000/ ha/year with conventional surface irrigation. Water limitation has restricted his cropping around 1 ha out of 3 ha during summer and the remaining area being kept fallow. After the inception of precision farming project (2007-08) in his site, one hectare was brought under cultivation with high yielding hybrid vegetables like Brinjal, Bhendi and Chillies. In Consequent years he has extended the area under cultivation of vegetables crops from 1 ha to 3 ha due to efficient use of water through drip irrigation. He realized the high yield from the vegetables (55 t/ha) by adoption of improved precision farming technologies like pro tray nursery, hybrid vegetable seeds, fertigation by water soluble fertilizers and recent plant protection measures with the intervention of KVK scientists. He is enjoying the fruition of this project by getting increased daily income from Rs.1,500day/ha to 3,000 day/ha as now and he has got Rs.4.23 lakhs / ha / year as net income during 2009-10.

Th. K. Meganathan of Eda Melaiyur village had earlier grown Rice, Groundnut, Gingelly and Pulses. After the KVK intervention, he is growing vegeatbles like Brinjal, Bhendi, tomato and Chillies under precision farming. The farmer has owning 8 hectares land with bore well. He cultivated rice, ground nut, gingelly, pulses and coconut in the existing cropping system. From this he earned around 20,000 to 25,000/ha/year with conventional surface irrigation. After the inception of precision farming project (2007-08) in his site, one hectare was brought under cultivation with high yielding hybrid vegetables like Brinjal and Bhendi. He realised the yield of vegetables was also increased from 20 t/ha to 38 t/ha by adoption of improved precision farming technologies like pro tray nursery, hybrid vegetable seeds, fertigation by water soluble fertilizers and recent plant protection measures and got Rs. 60,000/ha/year. With the continuous interventions of KVK scientists now he could get 61 t/ha (2009-10) from 1 ha brinjal crop and net income of Rs. 5,00,000/ha/year. He is also awarded with “Velanmai Chemmal Award” by TNAU for his achievement of higher yield of 61 t/ha /year in Brinjal under precision farming in rice belt.

Their net income was raised to the tune of 20 fold after adopting the precision farming. This clearly shows the strength of the technology and dedication of farmers who toiled with his mother earth for great success in the Rice bowl region of Tamil Nadu.

Inland fish culture

 

 

  Problem and Thrust area

 

The topography of the land in Thiruvarur District is flat terrain and soil type is heavy clay to clay loam which is periodically prone for prolonged water inundation and poor income from rice cropping. The soil in Thiruvarur District is heavy clay and clayey loam which retains water without any percolation loss. The soil is therefore highly suited for pond culture of fresh water. Thus the farmers are motivated on inland composite fish culture and making them to convert part of their land into inland fish pond for assured income

KVK interventions

 

Traditional inland fish culture was practiced in more than 300 ha. area in aqua ponds and 3321 ha. of seasonal tanks owned by panchayats during 2007-08. The traditional fish ponds well supported by the geographical features to harvest the rain water during monsoon. As there is scope for fish farming, the KVK took strenuous efforts in promoting inland fish culture through various interventions.The KVK is playing key role for promoting inland fisheries by conducting OFT, FLD, Demonstrations, Training, Exposure visits, exhibition, Publication of extension literatures, news through mass media and maintenance of Demo units.

In 2009-10, FLD on “Popularization of Inland fishculture in Cauvery Delta Zone for sustainable income” was conducted in 10 farmers holdings. Besides two on campus trainings on fisheries nutrition and inland fishery management and one vocational training on composite fish culture in collaboration with NABARD, Thiruvarur (27.01.2010 -30.01.2010) were organized. . In 2010-11, one OFT on “Polyculture in Inland fisheries in Delta region using stunted fingerlings” (in five locations) and one FLD on Popularization of scientific composite fish culture in inland fisheries (in four locations) were conducted.

A total of four numbers of training on “Inland fish culture” were conducted and totally 138 farmers of Thiruvarur district have participated and got trained in inland fish culture technologies by the way of seeing is believing.

Earlier the situation was growing of varieties which are more susceptible to pest and diseases. The farmers did not know about the improved crop management and protection technologies which realized low yield in cotton. Due to other problems like high price fluctuation, labour scarcity some of the farmers shifted from cotton cultivation to sugarcane and pulses. Due to high price fluctuation, farmers shifted from cotton cultivation to sugarcane and pulses.

 

Interventions of KVK

 

In order to address the said technological problems, KVK took interventions like FLD on Improved cotton technologies (50 Nos during 2007 – 08 , 50 Nos during 2008 – 09 and 50 Nos during 2009 – 10), FLD on farm machinery (75 Nos during 2007 – 08 and 75 Nos during 2008 -09) in 120 Ha of Thiruvarur district. Apart from this two OFT programmes on “Performance of alternative method of crop establishment in rice fallow cotton” and “Management of mealy bug in rice fallow Bt cotton production” conducted during 2007 -08. Besides one farm field school on “Integrated Pest Management in cotton” under Mini Mission II Technology on cotton was conducted in Therkupattam village of Valangaiman block during 2006 - 07.

By name Bt cotton was not accepted by the farmers, since they were not fully aware of technical knowhow of this technology. Hence, the KVK has taken as challenge of popularizing this technology to every part of this district. Initially it has been decided to popularize through FLD in villages where the cotton is grown in larger areas. Accordingly FLDs were conducted at Therkkupattam, Vadukku Pattam villages of Valangaiman block and Poongulam village of Nannilam block, Govindangudi village of Valangaiman block and Simili village of Kudavasal blocks in Thiruvarur district.

Overall adoption

78%

 

There were Totally 325 farmers participated in KVK intervention activities.

The overall adoption of improved cotton cultivation was 78 percent. The high level adoption of these cotton cultivation technologies among the farmers were purely because of the influence of KVK, Needamangalam. Remaining 22 percent of farmers have not adopted due to Non-availability of inputs and some personal problems. Interestingly all the farmers (100 %) adopted the Bt cotton hybrid

 

Impact of power weeder in cotton at village level

 

During 2007-08 power weeder for intercultural operation was included in Cotton FLD. This was widely demonstrated in 75 farmers holding and the same was continued during 2008-09 programme in 75 cotton farmers site. It had greater impact not only among the cooperating farmers, but now in the entire district where in more than 80% of the cotton farmers are doing their intercultural operations in cotton by power weeder

Even though the area under cotton cultivation has drastically decreased, the productivity of cotton per unit area has increased tremendously in Thiruvarur district. This is because of the adoption of Bt cotton (RCH 20) and improved cotton cultivation technologies demonstrated by the KVK, Thiruvarur among the farmers.

Supply of technological inputs

 

The scientists at KVK,Thiruvarur not only teach technologies to the farmers but also sell technological inputs from KVK farm in the form of seeds, seedlings, chicks, azolla, and vermicompost. This has got immense impact among farmers since they actually saw the benefit of technologies genuine and quality inputs received from a reputed institution.

The table given above would reveal the herculean efforts of KVK, Thiruvarur in producing and supplying technological inputs in particular the paddy seeds. The total distribution of seeds is 1049.04 quintal from 2005-06 to 2009-10 and the total no of farmers who got benefitted is 2233.

 

 

As KVK, Thiruvarur has been serving as a knowledge repository of rice in Thiruvarur district, the utmost concentration of the centre is on production of paddy seeds to cater to the needs of Thiruvarur district. It is evident from the figure given below that distribution of paddy seeds has followed an increasing trend with a maximum of 333 quintals distributed during the year 2009-10.

Another striking indicator which substantiate the impact of distribution of technological input is that the Revolving fund generation (RF) has phenomenally rose from Rs.35,611 in 2008-09 to to Rs. 5,82,000 in 2010-11. The amount may increase in coming years since demo units like composite fish culture is to be accounted for in ensuing year.

ü  Slatted Goat rearing unit

ü  Backyard Poultry Farming unit

ü  Rice-Drum seeding

ü  Rice-Transplanter

ü  Rice-System of Rice Intensification

ü  MN Mixture Unit

 

One such example is that Mr.Ganesh Kamalakannan of Enkan, Mr.Syed Ahamad of Boothamangalam and Mr. Rajendran of Thirumeni who visited slatted goat rearing unit at KVK, motivated by this idea and started their own slatted goat rearing units by getting Boer bucks from the demo unit of KVK. Thus apart from technologies, the input for the technology also were distributed which results in huge and immediate impact
