An experiment was conducted on experimental farm at Department of Agril. Meteorology, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during Kharif season 2017 entitled “Influence of weather parameters on growth and yield of different genotypes of green gram (vigna radiata. L) under different sowing dates” to study the phenology, accumulation of growing degree days (GDD), helio thermal units (HTU), heat use efficiency (HUE), helio-thermal use efficiency (HTUE) and performance of four sowing dates in main plot including D1 (24th MW), D2 (26th MW), D3 (28th MW) and D4 (30th MW) with four varieties in sub plot viz. Vaibhav, BM-4, BM-2002-1 and BM-2003-2 in split-plot design for our study purpose and as per package of practices. It was observed that GDDs increased significantly by 56.35 to 139.95 oC days, in early sowing. The green gram variety Vaibhav accumulated markedly higher GDDs, HTUs and PTU. On mean basis, D1 (24th MW) produced significantly higher grain yield (970 kg/ha) followed by D2 (26th MW) (910 kg/ha) whoever genotype BM-2003-2 (819 kg/ha) was significant than rest of varieties. The significant reduction in grain yield was recorded in late sowing date. The GDDs gradually increases from emergence to maturity in all the tested genotype irrespective of sowing date. Green gram genotype BM-2003-2 showed better performance in terms of HUE and HTUE followed by BM-2003-1 and BM-4 varieties giving higher yield, HUE and HTUE are identified under the varying growing environments, so as to suggest the appropriate sowing time of green gram Variety in Parbhani district.
