Effect of sowing dates on biochemical, yield and yield attributing parameters of mustard genotypes

Abstract

The field experiment was conducted during the 2023-24 growing season at the experimental farm of Agricultural Botany Section, College of Agriculture, Nagpur to evaluate the effects of various sowing dates on the performance of different genotypes of Indian mustard (Brassica juncea L.). This study included four Indian mustard genotypes viz., ACN-237, ACN-226, PM 26 and TAM 108-1 (sub factor) which were sown on five different dates viz., 15th October, 30th October, 15th November, 30th November and 15th December (main factor). The experiment was structured using a factorial randomized block design (FRBD) with three replications. Data revealed that genotype ACN-237 performed better under 15th October and 30th October as compared to other sowing dates and genotypes in terms of biochemical parameters such as chlorophyll content in leaves and oil content in seed. In yield and yield attributing parameters such as number of siliquae plant-1, number of seeds siliqua-1, seed yield ha-1 and harvest index showed higher values on 15th and 30th October sowing date in genotype ACN-237.
