EFFECT OF SPACING AND PHOSPHORUS ON GROWTH AND FLOWERING OF GLADIOLUS. Rajib RR, Naznin A, Shanta FH, Haque ANA, Amin MR

ABSTRACT

The field experiment was conducted at Dhaka, Bangladesh during the period from October 2011 to May 2012. The experiment consisted with two factors A: Three levels of spacing (S1, S2 & S3) and factor B: Four levels of phosphorus (P0, P1, P2 and P3). The result revealed that the highest number of spike (2,77,000 ha-1) was  recorded from spacing S2 and the lowest from spacing S1. In case of phosphorus, the highest number of spike (2,86,000 ha-1) was recorded from P2 and the lowest (189000 ha-1) was found from at P0. For interaction effect the highest number of spike (3,30,000 ha-1) was recorded from S2P2. So, the combination of 30 cm × 25 cm spacing with 150 kg P2O5 ha-1 is better for growth and flowering of gladiolus.
