Abstract:
An experiment was conducted during the Kharif seasons of 2016 at the soil science research farm of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.) to study the physiological growth and yield response of direct-seeded rice grown under combined application of fertilizers and manure according to targeted yield and STCR approach. The results revealed that growth indices like leaf area index (3.99), leaf area duration (42.90 days), crop growth rate (19.71 g m^-2 day^-1), relative growth rate (0.0642 g g^-1 day^-1), and net assimilation rate (0.086 g day^-1 m^-2) were higher with the application of 157:125:70 kg N, P₂O₅ and K₂O with 5 t FYM ha^-1. Grain and straw yield (5725 and 7623 kg ha^-1 respectively) was found to be highly significant with the integrated use of fertilizers and manures (T₆).
