Abstract
Background: Cowpea is a versatile leguminous pulse crop that exhibits resilience to drought and adapts well to various climates. It serves multiple purposes and can be enjoyed both in its raw form and as a grain pulse. Various studies established that cowpea has the potential vegetable crops with nitrogen fixation capacity. Thus, the study of environmentally safety and clean production of cowpea for better crop yield along with energy use efficiency and carbon budgeting for sustainable crop production is an important issue for the upcoming future. Methods: The present study was carried out at the experimental farm of Krishi Vigyan Kendra-Sepahijala, Latiacherra, Tripura under CAU (I) on 2022 and 2023 with three high yielding cowpea varieties (Kashi Kanchan, Kashi Gauri and Kashi Unnati). The design followed in the experiment adhered to a Randomized block design (RBD) with five replications. Result: Experiments result revealed that Kashi Kanchan perform outstanding by showing maximum pod yield. In the context of energy equivalent and Carbon budgeting, Kashi Kanchan is showing high energy use efficiency (45.01) and high carbon efficiency (1.59).
