Evaluation of Optimum Doses of Nitrogen in Relation to Yield and Quality of Brinjal (Solanum melongena L.) in Balaghat Region of Madhya Pradesh, India

Abstract

This study aimed to investigate the impact of varying nitrogen levels on the growth and yield of the brinjal variety Pusa Purple Long. The research was conducted at the Horticulture Department's field within the School of Agriculture Science, Technology and Research at Sardar Patel University, Balaghat, Madhya Pradesh, during the Rabi season of 2023. The experiment utilised a Randomised Block Design (RBD) featuring eight treatments, each replicated three times. The treatment combinations consisted of different doses of nitrogen. The findings indicated that T8 (N at 230 kg/ha, P at 150 kg/ha, K at 100 kg/ha) significantly enhanced vegetative growth (including plant height and number of branches per plant) and yield attributes (such as number of fruits per plant, fruit weight, and overall fruit yield). Additionally, T8 yielded the highest net returns and one of the most favorable benefit-cost ratios. Therefore, the integrated application of nutrients is recommended to boost crop productivity and improve the overall performance of brinjal in the Balaghat region of Madhya Pradesh.
