Abstract

Indian mustard (Brassica juncea L.) is an important oilseed crop, grown mainly in the North-West plains of India during rabi season (October to March). Soil moisture deficit and terminal heat stress are common problems during growing season due to low rainfall and delayed sowing, respectively. A field experiment was conducted during the rabi season of 2020-21 at IARI farm with three mustard cultivars, viz., Pusa Vijay, Pusa Mustard-21 and Pusa Bold in Split plot design to study the influence of irrigation levels and date of sowing on crop phenological stages/events of Indian mustard cultivars. Observations on crop Phenology were recorded twice a week at regular interval through keen observation on the field physically. The challenge during observing phenology was accounting every minute observation in the field regularly. Each date of delayed sowing progressively and significantly decreased the days taken to 50% flowering and maturity. There was delay of 15 to 20 days to attend 50 %

Conclusion

The time of sowing and different level of irrigation affect the phenology of the crop. The crop duration (emergence to harvest) reduced as there was delay in sowing and application of one irrigation instead of two irrigation. Optimum time of sowing and irrigation is necessary for proper growth and development of mustard crop.
