Evaluation of mustard genotypes under irrigated and rainfed conditions

Abstract

A field experiment was conducted during the 2023-24 cropping season at the Experimental Farm of the All India Coordinated Research Project on Linseed and Mustard and the Agricultural Botany Section, College of Agriculture, Nagpur, to evaluate the morpho-physiological responses and yield performance of Indian mustard genotypes under contrasting moisture conditions. Sixteen genotypes were evaluated under two sowing environments irrigated and rainfed using a factorial randomized block design (FRBD) with three replications. The findings revealed that genotype ACN-237 demonstrated superior performance across both conditions in key morpho-physiological parameters such as plant height, root-shoot length ratio, number of branches plant-1, and leaf area. Yield related attributes, including siliquae density, number of siliquae plant-1, 1000-seed weight, seed yield plant-1, and seed yield plot-1, were generally higher under irrigation. However, ACN-237 consistently outperformed others even under rainfed conditions, highlighting its broad adaptability to moisture stress.
