A field experiment entitled "to find out the different agro meteorological indices under different growing environments for chickpea crop" was conducted at the Research and Instructional farm of I.G.K.V., Raipur during rabi 2019-20. The treatments consisting of three Growing Environment (GEs) viz. 15 th Nov., 30 th Nov. and 15 th Dec. and three chickpea varieties viz. Vaibhav, JG -14 and JG -16 were laid out in Factorial RBD with 3 replications. The results found that the agrometeorological indices Accumulated Growing Degree Day (GDDs) at maturity stage were highest (2086) for Vaibhav under 15 th Nov. sowing maximum GDDs were observed in 15 th Nov. as compared to normal sown crop 30 th Nov. and late sown crop on 15 th Dec. at maturity stage. The maximum HTUs of (13487) was recorded for variety JG-16 sown on 15 th Nov. whereas second highest HTUs of ( 13189) was recorded for JG-14 in 30 th Nov. growing environment and next for Vaibhav (13374) under 15 th Dec. sown crop. Similar is trend for PTUs of chickpea varieties under different GEs. At maturity stage highest HUE and RUE is generally observed for normal growing environment. Vaibhav variety is found to be having highest HUE and RUE. It is followed by JG-14 and least value is being observed in JG-16 variety.
: A field study was carried out during Kharif 2014Kharif -15, 2015Kharif -16, and 2016 on thirty seven farmers field of Mohbhatta village of Simga block of the district Balodabazar-Bhatapara of Chhattisgarh state with size of trial is one acre each farmers to determine the impact of sowing techniques on yield of soybean under farmers' conditions. Soybean is more water stress crop and at the time of germination sudden rainfall affects the crop. For this purpose, broad bed planting technology was introduced in the study area to compare it with the conventional sowing of soybean by flat bed methods. Six-row broad bed furrow machine was used to plant soybean having top bed width of 2.35 cm. Result showed that growth character (plant height, number of branches per plant and number of root nodules per plant) and yield contributing character viz., number of pods per plant, seed yield weight per plant, seed index, seed yield,straw yield and harvest index (%) were found higher in broad bed furrow compared to the normal flat bed sowing which subsequently resulted in yield enhancement to the extent of 28.38 % for soyabean crop. The average yield in broad bed furrow method recorded 15.20 q ha -1 .The B:C ratio was observed 2.05 due to drainage of excessive rain water from the fields and stronger plant anchorage on the beds. Similarly, 40 to 50% saving in irrigation water was recorded with broad bed furrow method of soybean in comparison with flood irrigation of controlled plots. Results indicated that broad bed furrow technology has a lot of potential to increase water productivity of soybean.
