Abstract

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