on farm trials [oft] - KVK SULTANPUR U.p.
"Testing of any improved technology along with the farmers practice in the farmers field with active participation of both the scientists and farmers is known as OFT. In this method two to three improved varieties or two to three improved technologies are tested in the same field so as to compare the results of these treatments. As per the suggestions of the farmers as well as local soil and climatic conditions the improved technology may slightly be modified by the scientists of K.V.K. to get maximum return."

INTEGRATED CROP MANAGEMENT
Problem definition: Effect of Potash on bolting of Rabi Onion
Technology Assessed or Refined : Application of Potash as basal dose and foliar spray with NPK (18:18:18) @ 5 kg/ha. Bolting of Onion in Rabi crop affect the quality of onion as well as storage durability. The seedling were raised in Nov.-13 and planted in Jan-14 with application of 100kg of MOP as basal dose gave a yield of 173 q/ha, whereas, spray of NPK @ 5 kg/ha along with FP gave maximum yield 196 q/ha. Basal dose of DAP @ 110 kg and urea 80kg/ha gave lowest yield of 128q/ha.

PEST AND DISEASE MANAGEMENT
Problem definition: Wilting of chilli
Technology Assessed : Treatment of seedling with 0.2 % COC
Wilting in chilli due to root rot / collar rot became serious problem. The affected plants created a major gap and affected the plant population which reduces the yield drastically. To control the wilting, the seedlings were treated with 0.2 % COC liquid solution for 5 minutes before planting which reduces the wilting of plant and increases the yield of green chilli (88.4 q/ha). The mortality of plants were higher (36 %) with minimum yield of 56 q/ha.

INTEGRATED NUTRIENT MANAGEMENT
- Problem definition: Low productivity of pigeon pea due to under dose of nutrient
Technology Assessed : Foliar feeding of N at flowering initiation
Pigeon pea is an important pulse crop of Sultanpur distt but the farmers were mainly grew the crop in marginal soil with marginal package of practices. The farm trial was conducted to assess the effect of N with the foliar application of 2% urea solution at the time of flower initiation. From the observation, It has been noted that the yield was increased up to 25 % (16.80 q/ha) against the check 12.60 q/ha.

- Problem definition: Effect of foliar feeding on productivity of lentil under un- irrigated condition.
Technology Assessed : Foliar feeding of NPK (18:18:18) before flowering.
Lentil is often cultivated by the farmers under un-irrigated condition with marginal amount of fertilizer. NPK (18:18:18) was sprayed @5 kg/ha before flowering. The data was recorded on yield of grains (17.2 q/ha) followed by the crop without spray (12.6 q/ha).

- Problem definition: Effect of foliar feeding on yield of chick pea.
Technology Assessed : Foliar feeding of NPK (18:18:18) under un-irrigated condition
Chick pea is an important crop of pulse grown under un-irrigated condition with nominal dose of fertilizer and without inoculation of bio fertilizer. The seeds were treated with RC and PSB culture. The yield was enhanced after foliar feeding before flowering by 18.20 q than the crop raised with basal dose of DAP (12.5 q/ha).

VARIETAL EVALUATION
Problem definition: Assessment of salt tolerant var. of wheat in reclaimed sodic soil.
Technology Assessed : Two salt tolerant varieties KRL-210, 213 and two varieties (PBW-154, GW-273) seeds were treatment with CSR-Bio @3ml /kg of seed.
Sodicity was one of the major problem in distt. Sultanpur and a large number of small and marginal farmers were growing paddy and wheat without discriminating of wheat variety suited to their field condition. The kvk was procured two varieties of wheat i.e KRL-210, 213 which are tolerant to salt and two varieties viz PBW-154, GW-273. The seeds were treated with CSR-Bio @ 3 ml /kg of seed. Out of these varieties KRL-210 gave higher yield of 42.50 q/ha followed by KRL-213 (38 q/ha) and GW-273- ( 37.20 q/ha). Var. PBW-154 have lowest yield of 32.5 q/ha.
