INFLUENCE OF SPACING AND PHOSPHORUS ON GROWTH AND FLOWERING OF COCKSCOMB

Abstract

The experiment was conducted at the Horticultural Farm, Sher-e-Bangla Agricultural University, Dhaka, during the period from March 2012 to May 2012. The experiment consisted with two factors, such as factor-A: three levels of plant spacing; S three levels of phosphorus; P 1 : 35×20 cm, S o : 0 kg, P

2 : 35×25 cm and S 1 : 50 kg and P 2 3 : 35×30 cm and : 100 kg P /ha respectively. The experiment was set up in a Randomized Completely Block Design with three replications. Spacing and phosphorus fertilizer significantly influence on most of the parameters. In case of spacing, highest number of spike (126,582/ha) was obtained from S and the lowest (25,316/ha) from S 3 2 . For phosphorus, highest number of spike (101,265/ha) was obtained from P 1 and the lowest (20,320/ha) from P . For combined effect, highest number of spike (132,531/ha) was obtained from S o and the lowest (27,260/ha) from S 3 P treatment. So, 35×25 cm spacing with 50 kg P 2 O 5 o /ha is found best for growth and flowering of cockscomb.
