Abstract
A field study was carried out at Regional Agricultural Research Station, Rahmatpur, Barishal during Rabi 2019-2020 on wheat seed yield and quality influenced by different management practices. The experiment was comprised of two sowing dates with seven different agronomic management practices. The experiment was laid out in split plot design where sowing dates were assigned in main plot and different agronomic management practices in sub-plot with three replications. The results revealed that, optimum sowing condition (20th November) always maintain superiority over delayed sown condition (20th December) in respect of seed yield and quality. From agronomic management aspects strip tillage + recommended fertilizer doses+ 3 irrigations showed the best permormance in respect of seed yield (3.433 t/ha) and quality. From interaction effects of sowing date × agronomic management practices using strip tillage + recommended fertilizer doses+ 3 irrigations treatment with optimum sowing condition e.g. 20th November sowing condition performed the best in respect of seed yield (4.223 t/ha) and quality. Another two treatments (Strip tillage + recommended fertilizer dose + Boron foliar spray at anthesis (0.2%) + 2 irrigations (CRI, Booting) + Cowdung) and (Recommended fertilizer dose (NPKSMgZnB@ 120-30-90-15-6-2.6-1 kg/ha) + Boron foliar spray at anthesis (0.2%) + 3 irrigations (CRI, Booting, Grain filling) also produced statistically identical seed yield (4.15 and 4.01 t/ha, respectively). But considering economic point of view, (Recommended fertilizer dose + 0.2% boron foliar spray at anthesis + 3 irrigations) gave the highest BCR (2.46) and economic return. In late seeding condition (20th December) (strip tillage + recommended fertilizer doses+ 3 irrigations) treatment had performed the best in respect of seed yield (2.643 t/ha) and seed quality (germination 67.33%).
