Abstract: A detailed study on energy utilization in production agriculture was conducted at Assam Agricultural University, Jorhat, during rabi season of 2016-2017 and 2017-18 with four irrigation schedulings viz., irrigation at flower initiation stage; irrigation at flower initiation and 50% flowering stage; irrigation at flower initiation, 50% flowering and at siliqua development stage and rainfed with four different planting geometry viz., 30 cm × 30 cm, 30 cm × 25 cm, 25 cm × 25 cm and 30 cm × 5-7 cm. Application of irrigation at flower initiation, 50% flowering and at siliqua development stage recorded higher net return of energy (NER), whereas, energy productivity (EP) and energy use efficiency (EUE) was found highest at irrigation at flower initiation and 50% flowering stage. The lowest NER, EP and EUE were reordered under rainfed treatment. Among the planting geometries 25 cm × 25 cm recorded the highest NER, EP and EUE. However, specific energy (SE) was highest under rainfed and planting geometry 30 cm x 5-7 cm.
