Abstract:
The field experiment of the present study was conducted at the farm of BTC College of Agriculture And Research Station, Bilaspur, under Agronomy Department, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) in years 2019-20 and 2020-21. The experiment was conducted in split plot design in kharif crop and split-split design in rabi ratoon crop with 03 replications. Nine treatments were allocated in main kharif crop and 36 treatments were allocated in ratoon crop. There were two factors taken in main crop i.e. Main plot: planting geometry (P) and Sub-plot: nutrient management (N) whereas, three factors for ratoon crop i.e. Main plot: planting geometry (P), Sub-plot: nutrient management (N) and Sub-sub-plot: cutting management and foliar spray (CF). Among the different planting geometry in kharif pigeonpea, Among different planting geometry in kharif pigeonpea, maximum gross energy output, net energy output and energy output: input was recorded under P1 (60 cm x15 cm). While the lowest energetics was recorded under P3 (120 cm x 15 cm). Among different nutrient management practices, significantly maximum gross energy output (32571 MJ ha^-1, 31224 MJ ha^-1 and 31898 MJ ha^-1 during 2019-20, 2020-21 and on mean basis, respectively was recorded under N3 (125% of RDF). But input: output (7.70, 7.44 and 7.57 during 2019-20, 2020-21 and in mean respectively) was found maximum under N1-75% RDF. The net energy output was found to be non-significant under different treatments during both the years and on mean basis.
