Effect of Sowing Dates on Growth and Yield of Indian Mustard (Brassica juncea L.)

Abstract

To study effect of sowing dates on growth and yields of Indian mustard (Brassica junceaL.). Keeping in this view experiment was conducted in Split Plot Design (SPD) with three replications having two factors. First factor comprised of three dates of sowing (15 Oct, 10 Nov. and 05 Dec.) whereas, second factor consist of three Indian mustard varieties viz; Varuna, Narendra rai-1 and Kranti. Results showed that both dates and varieties (10 Nov. and Varuna) superior compare to rest of treatment. However, highest growth attributes (plant height, dry matter accumulation, Days taken to 50% flowering, number of tillers, LAI and yield and yield attributes (No. of siliqua (cm)per plant, length of siliqua (cm) test weight, seed yield(q/ha) grain yield, stover yield, biological yield, and harvest index) was recorded under 10 Nov. and Varuna variety, and oil character. At Lowest yield recorded under dates and varieties at 15 Oct. followed by 05 Dec. and Narendra rai-1 and Kranti. Among treatment, dates and varieties (10 Nov. and Varuna) showed effectively increasing the growth and yield and enhanced the nitrogen content efficiency and oil content and oil yield.

​Effect of Date of Sowing on Growth, Seed Yield and Economics of Indian Mustard (Brassica juncea) Varieties under Rainfed Conditions

“…Further monthly rainfall distribution pattern during the crop seasons of 16 th October sown crop showed that comparatively higher rainfall was received during November and January commentating vegetative and flowering stage of the crop, however normal rainfall was received during the month of February commentating siliqua formation stage of the crop which helped in terms of increased seed and stover yield. These findings are in close conformity with those of Kumar et al (2017) and Tripathi et al (2021). The 16 th October (24.7) sown crop recorded highest harvest index as compared to 23 th October (23.6) and 30 th October (24.6).…”

Impact of Humic Acid and Sulphur application on growth and yield of Indian Mustard under variable Water moisture regimes

“…The results demonstrated that the combined application of humic acid and sulphur significantly increased the weight of Siliqua per plant compared to control groups, across different water regimes. This finding suggests that these amendments play a crucial role in enhancing reproductive development and seed production [23]. Such improvements can contribute to higher crop yields, particularly in areas prone to water variability, thus fostering sustainable agriculture practices [13].…”

Effect of Different Sowing Dates and Varieties on Mustard Growth and Yield in Prayagraj Conditions

“…With the development of new varieties of crops and the adoption of multiple cropping systems under irrigated conditions, it has become essential to extend its sowing from October to mid-November or even later. Considering the above facts, field experiments were conducted to study the impact of different sowing dates on two commonly grown mustard varieties of mustard in north India [7][8][9][10].…”
