GROWTH AND YIELD OF CABBAGE AS INFLUENCED BY GA3 AND PHOSPHORUS

Abstract

The experiment was conducted in the Horticulture Farm, Shar-e-Bangla Agricultural University, Dhaka during October 2012 to March 2013. The experiment consisted of two factors: Factor A: Three levels of Gibberellic acidGA 3 i.e. G 0 : 0 1 : 70 and G 2 : 90 GA and Factor B: Four levels of phosphorus as- P 0 : 1 : 120; P 2 3 : 140 and P 3 : 160 kg P /ha, respectively. The two factorial experiment was laid out in the Randomized Complete Block Design with three replications. For gibberellic acid, the highest gross weight of head , while the lowest gross weight of head . For phosphorus, the highest gross weight of head 0 , whereas the lowest gross weight of head 2 . For combined effect, the highest gross weight of head 1 P 2 0 and the lowest gross weight of head 0 P 0. The highest BCR and the lowest 0 P 0 . So, 70 ppm GA 3 with 140 kg P 2 O /ha is the best for growth and yield of cabbage.
