Effect of Sowing Dates and Varieties For Higher Productivity Of Indian Mustard (Brassica juncea L.) – A Review

摘要

Rapeseed–mustard grown in diverse agro-climatic conditions ranging from north-eastern/ north-western hills to down south under irrigated/rainfed, timely/ late-sown, saline soils and mixed cropping. Sowing time is important in deciding the environmental conditions of crop, timing and rate of organ appearance while in crop growth analysis predicting of phenology is of prime importance. The crop is mainly grown during the winter season (October-March). Interpretation of physiological and phenological stages that causes reduction in yield with reference to date of sowing can help to develop strategies for improvement in the seed yield. Further, it will help in the assertion that productivity is constrained by development pattern and process physiology in response to environment. Moreover, response of different cultivars may differ under various sowing dates. Thus, optimum sowing date for a particular cultivar under consideration may play a great role in exploiting the yield potential of that cultivar.
