Pemberian Kalium pada Beberapa Kelembaban Tanah terhadap Pertumbuhan dan Produksi Jagung Manis (Zea mays saccharata Sturt)

Abstract

The objective of this research was to know influence of interaction between the potassium dosage and soil dampness level, and also influence of potassium dosage and soil dampness level toward sweet corn growth and production. It was conducted from May to July 2006. The result of the research can be summarized as follow: (1) Interaction between potassium  dosage and soil dampness level had  significant effect on cob weight without coat and dry cob weight, and the best combination was 225 KCl/hectare with 85% soil dampness level; (2) Potassium dosage and soil dampness level also had significant effect on cob weight without husk, which was 64,29% higher than those without potassium at similar soil dampness level. This was the result for 225 KCl/hectare and soil dampness of 85%.
