Pengaruh Dosis Pupuk KCl terhadap Pertumbuhan dan Hasil Jagung Manis (Zea mays saccharata Sturt.) pada Tanah Aluvial

Abstrak

This study was conducted in Kalinilam Village, Ketapang Regency, from May to July 2024, and aimed to evaluate the effect of KCl fertilizer dosage on the growth and yield of sweet corn (Zea mays saccharata Sturt.) grown on Alluvial soil. A Randomized Block Design (RBD) with a single factor was used, consisting of six dosage levels of KCl fertilizer repeated four times, with three sample plants for each replication, so that a total of 72 plants were observed. The treatments were K0 (control, without KCl), K1 (2 g/polybag), K2 (2.5 g/polybag), K3 (3 g/polybag), K4 (3.5 g/polybag), and K5 (4 g/polybag). The results showed that the application of KCl fertilizer had no significant effect on plant height, number of leaves, cob length, cob diameter, and cob weight per plant. The highest average values for all observed variables were nevertheless obtained in treatment K5, with plant height of 224.17 cm, number of leaves of 8.91 strands, cob length of 21.13 cm, cob diameter of 5.12 cm, and cob weight per plant of 98.75 g
