RESPONSE OF GIBBERELLIC ACID AND POTASH NUTRIENT ON GROWTH AND YIELD OF LATE PLANTING CABBAGE

Abstract

The study was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka to find out response of gibberellic acid and potash nutrient on growth and yield of late planting cabbage. The experiment consisted of two factors: Factor A: Gibberellic acid (four levels) as- G 0 : 0, G 1 : 90, G : 150 ppm GA K 2 3 and Factor B: Potassium fertilizer (three levels) as- K : 200 kg K 2 0 2 : 120, G : 0, K O. The two factors experiment was laid out in Randomized Complete Block Design with three replications. In case of different growth regulators, the highest marketable yield (65.1 t/ha) were found from G , while the lowest marketable yield (40.4 t/ha) from G . For different levels of potassium fertilizer, the highest marketable yield (64.4 t/ha) were recorded from K 0 , whereas the lowest marketable yield (44.6 t/ha) from K . Due to interaction effect, the highest marketable yield (75.6 t/ha) were recorded from G 0 2 K , whereas the lowest marketable yield (38.4 t/ha) from G 0 K 0 1 . The highest benefit cost ratio (2.31) was noted from the combination of G 2 K 1 and the lowest (1.24) from G . From growth, yield and also economic point of view, it is apparent that the combination of G 2 K 1 was suitable for late planting cabbage cultivation.
