Success Stories
Popularization of Bt cotton in rainfed black soil
Background
LRA 5166 and SVPR 2 are commonly cultivated in these tracts and the farmers are reluctant to go for cotton cultivation because of high production cost due to pests, diseases and weeds
Interventions
High seed cost of Bt cotton seed and so reluctant so KVK supplied the seed of RCH 2 and also Weeding is a menace and use of power weeder was used
Process
In rabi season 2006 a group of 25 farmers were selected from 2 adjacent villages, Periyakattankudi and PM Pudupaati of Aruppukottai block and they were convinced t go for Bt cotton RCH 2.
Technology
The presence of genes responsible for bollworm resistance in the Bt varieties helped to harvest a bumper yield in cotton
Impact
Horizontal Spread
About 10 per cent area of cotton has scope for spreading with Bt cotton
Economic gains
A farmer has additional income of Rs. 40000/- per crop by the use of Bt cotton
Employment Generation
Boll collection is more and easier than the normal cotton cultivation which creates increase yield thereby generates more income per day.
2. Title: IPM in cotton (Var: SVPR 2)
Background
Cotton cultivation is affected by pest and diseases and moreover this is a rainfed tract where drought is a common phenomenon where introduction of drought tolerant variety with strategic IPM measures will boost yield levels in cotton
Interventions
Seed availability is lesser and farmers are unaware about the drought tolerant variety
Process
Introduction of drought tolerant variety SVPR 2 with IPM strategies followed in villages Keelathulaknkulam and Melathulakkankulam of Kariapatti block
Technology
SVPR 2 with 150 days duration and yielding capacity of 1500 kg/ha Kappas was introduced and use of treated seeds, pheromone traps, neem oil, IPM kit, Trichogramma egg parasitoids etc which reflected on improved yield in cotton
Impact
Horizontal Spread
About 30 per cent area of cotton has scope for spreading with SVPR2 cotton variety
Economic gains
A farmer has additional income of Rs. 20000/- per crop by the use of SVPR2 cotton variety
Employment Generation
Since flowering is started after 75 days (it starts flowering by 50 days in varietiy like LRA 5166) the boll yielding period is also extended and the cotton plant stand is prolonged to entire summer till next rainfed season. Supplemental irrigation still increases the yield
3. Title: Integrated Nutrient management in rainfed groundnut
Background
The variety TMV 7 in groundnut is widely cultivated in the district in two seasons Kharif and Rabi using the SW monsoon and NE monsoon rains respectively where yield level is very low. Hardly an yield level of 750- 1000 kg/ ha is obtained
Interventions
Farmers are unaware of use of gypsum or any other micro nutrient and improper dose of fertilizer application
Process
In rabi season , villages of adjacent areas were selected where in application of gypsum along with recommended dose of fertilizers based on Soil test was followed
Technology
Gypsum application increased the number of filled bolls and yield level increased with application of recommended fertilizers
Impact
Horizontal Spread
A cluster of villages surrounding the kariapatti block and Narikudi block can be seen with this improved practice
Economic gains
A farmer has additional income of Rs. 5000/- per crop per ha
Employment Generation
Improved production due to gypsum application which creates increase in per day productivity
Raising vegetable nursery in portrays
Background
Precision farming technologies were demonstrated in Virudhunagar district by Krishi Viygan Kendra, Aruppukottai, Virudhunagar during 2007 – 08. The farmers were taken to Krishnagiri and Dharmapuri district on exposure visit and were explained about importance of drip irrigation, methods of raising nursery in protrays and maintenance in shade net. After seeing the shadenet at Paiyur, a farmer Shri. N.Srinivasan, residing at Melathulakkankulam village had erected a shadenet in his farm with local materials at a cost of Rs. 15,000/-.
Interventions
Chillies, tomato and brinjal seeds were sown in portrays with cocopeat. The portrays and cocopeat was purchased from Dharmapuri. While sowing, the portrays were filled with cocopeat and seeds were sown. Ten portrays were arranged one on the other and covered by a polythene sheet and kept as such for four days. On 5th day the polythene cover was taken out and water was sprinkled by rose cane. Afterwards the seedlings were maintained in the shade net.
Impact
Horizontal spread
Farmers had accepted the benefit of raising nursery in protrays rather than in nursery bed. Because of better establishment of seedlings in main field, farmers feel that gap filling is is much minimized as pro tray seedlings established well.
Economic gains
The farmer had raised 55,000 seedlings (Tomato Seedlings : 20,000, Brinjal seedlings: 15,000 and Chilli seedlings : 20,000) during last year using protrays with cocopeat. He sold the seedlings to farmers of his own village at a cost of 55 paise/seedling. By which he earned about Rs. 30,250/-. The expenditure for producing the seedlings was Rs.10,600/- and he had got a net income of Rs.19,650/-.

Employment generation
The seedlings are raised in shade net and sold to other farmers at a reasonable price. His labourers were skill trained in handling pro trays and nursery techniques. Many landless labourers have got employment opportunities. |
