Effect of phosphate and potash fertilizer on growth and yield of cabbage (Brassica oleracea L.) green coronet cultivar
1992
Subhan (Balai Penelitian Hortikultura, Lembang (Indonesia))
The experiment was conducted at Farmer's Land in Rancamanyar Village Pangalengan, at the altitude of 1450 m above sea level starting from August to December 1990. A Factorial Randomized Block Design was used in this experiment with two factors and three replications. The first factor was phosphate fertilizer dosage i.e : P0 = O P2O5 kg/ha, P1 = 100 P2O5 kg/ha, P2 = 150 P2O5 kg/ha, and P3 = 200 P2O5 kg/ha; and the second factor was potash fertilizer dosage i.e; K0 = 0 K2O kg/ha, K1 = 100 K2O kg/ha, K2 = 150 K2O kg/ha, and K3 = 200 K2O kg/ha. The result indicated that there was no interaction effect between phosphate and potash fertilizer dosages, but for each fertilizer had significant effect on plant height and leaf number at 30 days after planting, gross weight per plant, gross weight per plot, also on net weight per plot and no significant difference on plant height, leaf number and crop diameter at 50 days after planting
