摘要
Appropriate planting time of mustard (Brassica sp.) during winter deter-mines the growth yield and quality of a particular cultivar. Since the shift of winter period over the last few years driven by climate change, a transfor-mation in mustard cultivation is also observed. Thus, to study the extent of these variations we studied 6 mustard varieties (V1- Binasarisha-4, V2- Bina- sarisha-9, V3- Binasarisha-10, V4- BARISarisha-14, V5- BARI Sarisha-16 and V6- BARI Sarisha-17) under 3 different planting dates (D1-31st October, D2-10th November and D3-20th November) in the Magura district of Bangladesh to evaluate yield differences over sowing times. Field experimentation was set followed RCB (Randomized complete block) design. Data on growth and yield parameters were collected at various days after sowing. Outcomes noted that, most number of siliqua/plant was obtained with treatment com-bination D3 X V5 (190.33), siliqua length with D3 X V2 (7.95 cm), number of seeds per siliqua by D3 X V6 (36.30), thousand grain weight by D1 X V1 (3.90 g). Hence, correlation study suggested that, seed yield was positively related to number of siliqua/plant, siliqua length and number of seeds/siliqua. Though, BARI Sarisha-16 (V5) delivered top seed and stover yield in all sow-ing dates. But interaction effects depicted that planting on 10th (2.00 t/ha) and 20th November (1.99, 1.94 t/ha) gave similar seed yield like 31st October planting (2.31 t/ha); in addition, stover yield (6.70, 6.83 t/ha) also remained at peak with the later plantings (D2, D3). An increase in the tendency of life duration was noticed when sown on 20th November for most treatment combination. Overall, delayed sowing of mustard didn't affect the yield and related attributes rather it accelerated to some attributes. Hence, resched-uling of optimum sowing time for mustard is now a time demanding con-cern with regard to weather change.
