EFFECT OF VARIETY AND SEED RATE ON THE YIELD OF KENAF (Pages : 23 - 28)

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensigh during April to September 2011 to study the effect of variety and seed rate on the fibre yield of Kenaf. The experiment comprised three varieties viz. HC-2, HC-95 and HC-3 and three seed rates viz. 10, 15 and 20 kg ha-1. The experiment was laid out in a randomized complete block design with three replications. Variety, seed rate and their interactions significantly influenced plant characters and yield of kenaf. The highest plant height (193.04 cm), plant diameter (0.94 cm) and stick diameter (0.74 cm) were recorded in variety HC-2 while the lowest value was recorded in HC-95. The highest fibre yield (6.55 t ha-1) and stick yield (11.36 t ha-1) were obtained in HC-2 followed by variety HC-95 and the lowest fibre yield (4.99 t ha-1) and stick yield (8.44 t ha-1) were obtained in HC-3. The tallest plant (198.58 cm) was obtained at the seed rate 10 kg ha-1 and the shortest plant (184.74 cm) was recorded at the seed rate 15 kg ha-1. The highest plant diameter (1.11 cm), stick diameter (0.91 cm) and thickness of skin (0.19 cm) was recorded at the seed rate 15 kg ha-1 while the lowest values were recorded at the seed rate 20 kg ha-1. The highest fibre yield (6.35 t ha-1), stick yield (10.28 t ha-1) and harvest index (38.21%) were obtained at the seed rate 15 kg ha-1 while the lowest fibre yield (5.36 t ha-1) and harvest index (35.95%) were found at the seed rate 15 kg ha-1. The highest fibre yield (7.21 t ha-1) and stick yield (12.12 t ha-1) were obtained from the variety HC-2 with 15 kg ha-1 seed rate and the lowest fibre yield (4.28 t ha-1) and stick yield (8.11 t ha-1) were obtained from variety HC-3 with seed rate 15 kg ha-1 and HC-3 with seed rate 20 kg ha-1, respectively. From the study it can be concluded that variety HC-2 with seed rate 15 kg ha-1 is the promising combination to obtain the highest fibre and stick yields of kenaf. Download
