A field experiment was conducted during rabi season of 2017–19 at the All India Coordinated Sorghum Improvement Project, Mahatma Phule Krishi Vidyapeeth Rahuri to assess the effect of temperature and rainfall regimes on growth phases and biological yield components in rabi sorghum genotypes. The experiment consisted of thirteen genotypes evaluated in three rabi season. In the rabi season 2017 and 2018 there is there is sufficient rainfall at the time of sowing. Also maximum and minimum temperature ranges between 24 to 33 0C. At the time of flowering maximum and minimum temperature ranges between 15 to 28 0C. Genotypes come to flowering in between 71 to 89 days after sowing. Phule Anuradha shows very early flowering in rabi 2017 and 2018 season. In rabi 2019 due to change in rainfall and temperature there is significantly reduction in days to days to maturity. Phule Anuradha matures very early (107 days). BJV 362 gave higher biological yield (217 gm) in 2017 and RSV 2541give higher biological yield per plant (215 gm) in 2018. The biological yield reduces significantly in 2019.

A field experiment on Effect of potash levels and apportioning time on yield and economic of summer groundnut under drip irrigation was carried out at All India Co-ordinated Research Project on Summer Groundnut, M.P.K.V., Rahuri. The pod and hualm yield were significantly increased under groundnut crop grown with potash level 30 kg K2O ha-1 as compared to other potash levels. The dry pod yield kg ha1, kernel yield kg ha-1 and dry haulm yield kg ha-1 were significantly increased in potash apportioning time at 75 DAS with 10 splits. The potash level 30 kg K2O ha-1 significantly increased gross and net monetary returns as compared to other potash levels. The gross monetary returns (Rs. 171807 ha-1), net monetary returns (Rs. 110793 ha-1) and B:C ratio (2.82) were recorded with 30 kg K2O ha-1. Treatment K3 i.e. 30 kg K2O ha-1 yielded better results than other potash levels. The gross (Rs. 157135 ha-1) and net monetary returns (Rs. 95985 ha-1) and B:C ratio (2.57) were significantly more at potash apportioning time 75 DAS with 10 splits followed by potash apportioning time at 60 DAS with 8 splits.

A field experiment on Standardization of potash levels and apportioning time in summer groundnut under drip irrigation was carried out at All India Co-ordinated Research Project on Summer Groundnut, M.P.K.V., Rahuri. The pod and hualm yield were significantly increased under groundnut crop grown with potash level 30 kg K2O ha−1 as compared to other potash levels. Pod weight plant−1 and hualm weight plant−1 is higher in 30 kg K2O ha−1 potash level compared to 10 and 20 kg K2O ha−1potash level. The potash level 20 kg K2O ha−1 was at par with 30 kg K2O ha−1 for dry pod weight plant−1. The number of pods plant−1, dry pod yield kg ha−1, kernel yield kg ha−1 and dry haulm yield kg ha−1 were significantly increased in potash apportioning time at 75 DAS with 10 splits. The combination of 30 kg K2O ha−1 and fertigation at 75 DAS (10 splits) produced significantly higher pod yield than other combinations.

Experiment was carried out to study the effect of seed priming and foliar spray on grain and fodder yield of rabi sorghum. The thousand grains weight (g) of rabi sorghum was significantly higher with seeds primed with KNO3 @ 0.5% for 10–12 hrs (34.13 g) as compared to other seed priming treatments. The seeds primed with KNO3 @ 0.5% for 10–12 hrs recorded significantly highest grain (2657 kg ha−1), fodder yield (6451 kg ha−1) and biological yield (9108 kg ha−1) as compared to other treatments and it was at par with seeds primed with KH2PO4 @ 0.5% for 1012 in respect of grain yield (2588 kg ha−1). The thousand grains weight (g) of rabi sorghum was produced significantly higher with foliar spray of KNO3 @ 2% at 55 days after sowing (30.66 g) as compared to other foliar sprays. The foliar spray of KNO3 @ 2% at 55 days after sowing significantly produced higher grain (2559 kg ha−1) and fodder yield (5616 kg ha−1) as compared to other foliar spray. The percentage grain yield increase over control was 13.08, whereas additional grain yield increase was 310 (kg ha−1) over control.

The application of 125 % N level of RDF ha -1 significantly increased the growth attributes viz., plant height, number of leaves plant -1 , dry matter plant -1 , number of internodes plant -1 at harvest as compared to rest of the nitrogen levels and it was remained at par with the application of 100 % N of RDF ha -1 .The application of 125 % N level of RDF ha -1 significantly increased forage weight (g) plant -1 , forage production kg day -1 and forage yield t ha -1 (60.6 t ha -1 ) compared to other treatments.

The grain yield of pigeonpea was obtained by sole pigeonpea (1988 kg /ha) and the lowest when pigeonpea was intercropped with rajmah (1060 kg /ha). Three rows of mungbean intercropped in pigeonpea gave highest grain yield (1391 kg/ha) than three rows of rajmah intercropped in pigeonpea (1332.kg/ha). However, pigeonpea equivalent yield, net returns, LER and benefit cost ratio were higher with pigeonpea + mungbean inter cropping system (30.00 q /ha, Rs 33,553 /ha, 1.34 and 3.23 respectively) over sole crop of pigeonpea (19.88 q /ha, Rs. 24,512 /ha, 1.00 and 2.51 respectively).

Three hundred forty seven front line demonstrations on chickpea were conducted on different modules during the year 1998-99 to 2006-07. The gap between conventional practices and improved package of practices was much higher ranging from 115 kg /ha to 575 kg /ha. There is need to make stronger the extension services for educating the cultivators in the implementation of improved technology. Under irrigation management demonstration, the technology gap was much higher i.e. 575kg /ha.

Field experiment was conducted during rabi 2000 revelaed that foliar spray of N through urea 3% gave significantly higher grain yield (1001 kg/ha.), while it was at par with urea 2% (973 kg/ha) and DAP 2% (954 kg/hal.

A Field experiment was conducted during the winter season 1999–2000 to study the requirement of water on the basis of IW: CPE ratio and phosphorus requirement of chickpea. Irrigation at 0.4 IW: CPE ratio gave maximum (1804 kg/ha) and significant higher grain yield than no irrigation and irrigation at 0.2 IW: CPE ratio. The grain yield increased with increasing dose of P upto 60 kg/ha.

Field studies consisting of eleven weed control treatments were conducted during rabi 1994–95, 1995–96 and 1996–97. The pooled results indicate that unchecked weed caused 56.45%, 100.75% and 140.00% reduction in the grain yield during 1994–95, 1995–96 and 1996–97 seasons respectively. Application of Pandimethalin at 0.75kg/ha+one hand weeding at 45 DAS recorded highest yield than the other treatments. This treatment also gave highest net profit of Rs. 14,000/ha and benefit cost ratio of 2.18.

A field experiment was conducted during ihe winter (rabi) season of 1991-92 ulid 1902-93 to study the performance of 3 varieties (Seeta, Pusa Bold and Pusa Barani) of Indian ~iiustard [Brassica jtmcea (L.) Czernj & Cosson] under 5 sowing dates (1,15, 30 October; 15 and 30 November), Hlghest seed yield was recorded when the crop was sown on 1 Octobcr and subsequent sowing at an interval of 15 days induced significant reduction in seed yield during boll1 the years. Secd yield of Seeta was higher than PusaBold and Pusa Barani in both years.

A field experiment was conducted during the winter (rabi) season of 1991-92 and 1992-93 to study the performance of 3 varieties ('Seeta', 'Pusa Bold' and 'Pusa Barani') of Indian mustard [Brassica juncea (L.) Czernj & Cosson] under 5 sowing dates (1, 15, 30 October; 15 and 30 November). Highest seed yield was recorded when the crop was sown on 1 October and subsequent sowing at an interval of 15 days induced significant reduction in seed yield during both the years. Seed yield of 'Seeta' was higher than 'Pusa Bold' and 'Pusa Barani' in both years.
