Effect of Age and Depth of Seedlings of Kasturi Aromatic Rice on Fodder and Yield Performance during Aman Season in Bangladesh

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July to December, 2023 to evaluate the effect of age and depth of seedlings on the yield performance of Kasturi aromatic rice in aman season. The experiment comprised of four ages of seedlings viz. 25 days, 30 days, 35 days and 40 days and, depth of seedlings viz. 2 cm, 4 cm, 6 cm. The experiment was laid out in a randomized complete block design with three replications. The highest grain yield (2.76 t ha-1) and straw yield (6.52 t ha-1) were achieved from 30-day old seedlings. On the other hand, the lowest number of grain yield (2.34 t ha-1) and straw yield (4.35 t ha-1) were obtained from 40-day old seedlings. The highest grain yield (2.67 t ha-1) and straw yield (5.76 t ha-1) were obtained from 4 cm depth of seedlings whereas the lowest grain yield (2.48 t ha-1) and straw yield (5.00 t ha-1) were obtained from 6 cm depth of seedlings. The highest grain yield (3.01 t ha-1) and straw yield (6.81 t ha-1) were obtained from the combination of 30-day old seedlings with 4 cm depth. Thus, 30-day old seedlings and 4 cm depth of seedlings appeared as the best combination for obtaining the highest grain yield of Kasturi aromatic rice in aman season.
