INFLUENCE OF SPACING AND PHOSPHORUS ON GROWTH AND FLOWERING OF COCKSCOMB

The experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka, during the period from March 2012 to May 2012. The experiment consisted three levels of plant spacing; S₁: 35×20 cm, S₂: 35×25 cm and S₃: 35×30 cm and three levels of phosphorus; P₀: 0 kg, P₁: 50 kg and P₂: 100 kg P₂O₅/ha respectively and was conducted in Randomized Completely Block Design with three replications. In case of spacing, highest number of spike (126,582/ha) was obtained from S₂ and the lowest (25,316/ha) from S₃. For phosphorus, highest number of spike (101,265/ha) was obtained from P₁ and the lowest (20,320/ha) from P₀. For combined effect, highest number of spike (132,531/ha) was obtained from S₂P₁ and the lowest (27,260/ha) from S₃P₀ treatment. S₀, 35×25 cm spacing with 50 kg P₂O₅/ha is found best for growth and flowering of cockscomb.
