An experiment was conducted during Rabi seasons of 2013-14 and 2015 at RVSKVV, Special Agriculture Research Station, Farm, Bhind (M.P.) with 3 sowing dates and 3 fertility levels treatments. The experiment laid out in Split Plot Design with 3 replications on the basis of two year pooled data result revealed that sowing on 25 th November with 120:60:40kg/ha NPK, application gave significantly higher grain yield (4.22 t/ ha) and net return (Rs. 53850/ha). Result also prove that the optimum date sowing (25 November) revealed maximum yield attributes, plant height (84.50cm), ear length (8.91cm), grains/ear (47.32) and test weight (39.79g) which were significantly higher than all other showing dates.

The present study was conducted in Gwalior district of Madhya Pradesh during 2007-08 to 2011-12 in 25.20 ha of land with 63 frontline demonstrations have been conducted in Nikodi, Udaipur, Sirol, Bhadrauli, Hiri villages of Gwalior in sandy loam to clay loam soils with the active participation of farmers with the objective to demonstrate the improved technologies of green gram. The improved technologies of green gram consisted of use of improved varieties, seed treatment with Rhizobium culture and PSB (Phosphate soluble bacteria), balance dose of fertilizers,YVM resistance varieties, integrated pest and diseases management and integrated weed management. The average yield of green gram in frontline demonstration recorded higher (9.65q/ ha) as compared to farmers practice (6.75 q/ha). The average increased in the demonstration yield over farmer's practice was 42.96 per cent. The technology gap, extension gap and technology index were recorded 2.59 q/ha, 2.23 q/ha and 25.94 per cent, respectively. Improved technologies gave higher net return (Rs. 17685 per ha) with a benefit cost ratio 2.73 as compared to farmers practice (Rs.11463 / ha) benefit cost ratio 2.14.

The study was carried out to know the gap between improved packages of practices in gram crop. Frontline demonstration on gram varieties J.G.16, JAKI 92-18 and J.G. 130 were conducted at farmer's field in the adopted village of Krishi Vigyan Kendra, Lahar Bhind (M.P.) during the years 2010-11 to 2014-15. The average yield of J.G. 16 variety was 18.07 q/ha. J.G. 16 has given 20.4 q/ha. Highest yield during the year under frontline demonstration while local varieties gave 16.61 q/ha average yield during the year. The variety JAKI-9218 was demonstrated during 2011-12 and 2012-13 gave average yield at the farmers field 17.32 q/ha and 15.99 q/ ha, respectively. While variety conducted farmers practice gave average yield 13.62 q/ha and 13.52 during the years, respectively. The variety was given 18.50 q/ha. Highest yield under FLD, while farmers practice given highest yield 13.90 q/ha. The variety conducted under front line demonstrated was gave 27.16 per cent and 18.26 per cent higher yield over farmers practices during 2011-2012 and 2012-13, respectively. The average B.C. ratio of demonstrated technology was 1:180. J.G. 130 variety of gram tested at farmers field during 2012-13 and gave average yield 17.56 q/ha. While it was 13.1q/ha. in farmers practice. 34.04 per cent increased yield was recorded over farmer's practices. The variety JG 130 also demonstrated in farmers field under frontline demonstration during 2013-14 and 2014-15 in 10.40 ha land on 26 farmers field, this variety during the years could not sown its performance due to rainfall and hailstorm during flowering to maturity. The average yield during the years (2013-14 and 2014-15) was 6.13 and 2.53 q / while it had been seen in case of farmers practice 3.93 q/ha and 2.50 q/ha, respectively. Sixty four demonstration have been conducted during 2010-11 to 2014-15 in 25.80 ha of land. It could be said the yield performance of variety under improved package of practices not only in favour of increased yield but also economic condition of the farmers of the district

The study was conducted in Bhind district of M.P. during 2014-15 to 2016-17. Total eighty on farm trails at farmers field in different villages i.e. Jaganpura, Bespura, Bhikampura, Chiruli, Ruhani Jagir and Devarikala during the years from active participation of district farmers with the to improve the productivity of mustard crop in the district. The improved technologies consist improved varieties i.e. NRCDR-02 and Pusha mustard 28 were trials at farmers field during the years. It has been seen that the improved variety of mustard i.e. NRCDR 02 recorded average higher yield (16.96 q/ha), while it has been observed 16.01 q / ha. In case of pusa mustard 28. Farmers practice average yield during the years was observed 14.88 q/ ha. The average percentage in yield increased over farmers practice during the years was 11.03, while it was observed in case of NRCDR-02 and Pusa mustard 28 i.e. 12.57 and 9.48 per cent, respectively over farmers practice during the years. Pusa mustard 28 has taken less maturity days (about 14 to 20 days) as compared to NRCDR 02 and pusa mustard 28. The tabulation, mean, B.C. ratio and percentage have been used to draw the results from the data.
