EVALUATING THE IMPACT OF WEED MANAGEMENT PRACTICES ON ENERGY BUDGETING IN RAINFED CASTOR

A field experiment was done at Regional Agricultural Research Station (RARS), Palem during kharif, 2023 to evaluate the different weed management practices on energy budgeting in rainfed castor.The experiment was carried out in randomized block design with nine treatments and three replications.The results of the study revealed that higher input energy (10169 MJ ha -1 ), output energy (70868 MJ ha -1 ) and net energy (60699 MJ ha -1 ) was obtained with weed free (Hand weedings) but the higher energy use efficiency (7.2) and energy productivity (0.54 kg MJ -1 ) was recorded in case of treatment withdiclosulam 84 % WDG 31 g a.i.ha -1 as PE fb quizalofop-p-ethyl 15 % EC 50 g a.i.ha -1 as PoE at 30 DAS (T 1 ) and was on par with diclosulam 84 % WDG 31 g a.i.ha -1 as PE fb intercultivation with power weeder at 30 DAS (T 3 ).
