The incidence of Liriomyza trifolii Burgess on tomato (Solanum lycopersicum L.)at Pantnagar during the cropping season 2011-12 and 2012-13 revealed that the pest exhibited its incidence almost throughout the crop season marked its first appearance in 8th and 9th standard meteorological week (SMW) i.e. (February and March), attain peak population in 14th and 17th SMW (April), respectively. The pest population exhibit non significant correlation with various abiotic factors, except significant positive correlation with sunshine hours and significant negative correlation with morning and evening relative humidity during 2012-13.

The experiment was conducted at farmer’s field of Panagar, District Jabalpur (M.P.). During rabi season 2008-09 and 2009-10. The experiment was laid out in randomized block design with eleven treatments including control and replicated three times and results were showed in pooled basis. The maximum number [1] of flowers per cluster, number of fruits per cluster and percentage of fruit set was highest in T7 (Mixture of all). T10 (Azotobacter + Azospirillum @ 1 kg/ha each as seedling treatment) recorded highest number of flowers per cluster [3] and number of fruits per cluster [11]. While percentage of fruit set did not vary significantly due to bio-fertilizers. Maximum fruit diameter, fruit length, fruit weight and number of fruits per plant were observed for T7 (Mixture of all) amongst treatments of micronutrients. Maximum fruit diameter, fruit length, and fruit weight was highest in T10 (Azotobacter + Azospirillum @ 1 kg/ha each as seedling treatment) whereas number fruits per plant were higher in T8 (Azotobacter @ 1 kg/ha as seedling treatment) amongst treatments of bio-fertilizers. T7 (Mixture of all) recorded the highest yield per plant and yield q/ha followed by T6 (Manganese sulphate (Mn) @ 100 ppm as foliar spray) and T5 ( Ferrous sulphate (Fe) @ 100 ppm as foliar spray). Yield per plant and yield q/ha did not vary significantly due to bio-fertilizers.

Krishi Vigyan Kendras are the keys for facilitating the agricultural technology among the farmers field through Front Line Demonstration. This is the only way to make the reach about new technology at field level and way to collect first information regarding technology. Among high yielding varieties in okra, brinjal and tomato highest yield obtained 180 q/ha, 540 q/ha and 430 q/ha respectively. The demonstration conducted by KVK, Katihar and Nalanda on different high yielding vegetables recorded significant higher yield as comparison to control i.e. (farmers practice). Similarly, Spinach variety Pusa Anmol recorded maximum yield. Radish variety Pusa Chetki, Cauliflower Variety Sabour agrim and Carrot variety Pusa Kesar recorded highest average yield over farmers practice. Pusa Kesar and Sabour Agrim varieties were highly preferred by the farmers of Katihar district due to earliness of these cultivars. The extension gap is for most of the varieties/ hybrids were recorded more except Sabour Agrim, Pusa Kesar and Pusa Anmol. Low technology index regarding these varieties indicates to educate the farmers and it showed there is an urgent need to trained the farmers for rapid transfer of technology at field level.

Field experiments were conducted during rabi season in 2011-12, 2012-13 to 2014-15 to study the effect of different methods of drip fertigation and varieties on growth, yield, water and nutrient use efficiency and economics of potato. Results showed that drip fertigation of 100% of recommended dose of N and K at 9, 16, 23, 30, 37 43, 51, 58 and 65 days after planting markedly increased growth attributes like plant emergence and plant height and ultimately gave significantly higher>75 g grade and total tuber yield of potato over conventional method. Further, this method had improved crop productivity, water and nutrient use efficiency along with more net return and benefit-cost ratio, which was much higher than conventional method. Although, Kufri Pukhraj registered highest total tuber yield, with slightly higher crop productivity, water and nutrient use efficiency, net return and benefit-cost ratio, the difference between varieties of potato was non-significant.

One of priority research area in rice is identification of suitable genotypes for rain fed condition. Quantifying the drought tolerance genotypes was done with different stress indices obtained from the yield data under severe drought and irrigated condition with four backcross inbred lines derived from the cross between IR64 (drought susceptible) and Apo (drought tolerant) which carried three mega QTL in different combination of classes namely qDTY2.2, qDTY3.1 and qDTY8.1. The genotype CB 229 is the highly tolerant one confirmed by tolerant and susceptible indices, which had three DTY QTL (qDTY2.2, qDTY3.1 and qDTY8.1) combinations maximizes the yield in drought condition. Among the selection indices, YI, MPI, DRI, STI, HM, GMP, MRP and RE are the best indices to identify tolerant genotype. Clustering based on principal component analysis exhibits that CB 229, CB 193-2 and CB 193-3 falls on the quarter where tolerant indices found. Overall study shows that the selection based on stress indices may be rewarded to identify superior genotypes under severe drought condition.
