Effect of Date of Sowing in Mustard (Brassica juncea L.) Genotypes on Seed Growth and Yield

Three genotypes of mustard NRCHB – 101, PM-25 and PM-30 were sown during November- December in three different dates at an interval of fifteen days to know the effect of sowing date on seed yield and quality of mustard (Brassica juncea L.). The experiment was conducted at farmer’s field during Rabi 2019-2020 and Department of Seed Science and Technology College of Agriculture Raichur and Department of Crop Physiology, University of Agriculture Sciences Raichur, (India). Significant variations due to different sowing dates were observed in plant height, number of primary branches palnt-1, number of secondary branches plant-1, chlorophyll content, number of siliqua plant-1, number of seed siliqua-1, 1000 weight, yield plant-1and yield ha-1 and oil content of mustard. Delay in sowing caused a significant reduction in the seed yield and oil content. Results showed that the highest seed yield was1962.48 kg ha-1 obtained at early sown condition 2nd week of November. The lowest seed yield was 1902.10 kg ha-1 from 2nd week of December late sown condition. From the results, the best sowing date of mustard is on 2nd week of November in the northern parts of Karnataka.
