The Effect of Granular KCl Fertilizer Dosage on K-available, K-uptake, and Yield of Sweet Corn (Zea mays saccharata sturt.) in Inceptisol from Jatinangor

This research aimed to determine the effect and best granular KCl fertilizer dosage in increasing K-available, K-Uptake, yield of sweet corn (Zea mays saccharata Sturt.) Talenta variety on Inceptisols from Jatinangor. The method used was a randomized completely block design (RCBD) with nine treatments three replications. treatment consists without fertilization as control (A; N, P, K (B); ¼ + P (C); ½ (D); ¾ (E); 1 (F); 1¼ (G); 1½ (H); 1¾ (I). results showed that affected available K, uptake, yields. dose had combination single 100 kg ha-1 granules which produced cob weight 0.49 plant-1 Inceptisol
