Peningkatan Produktivitas Jagung Manis dengan Perlakuan Kapur Dolomit dan Pupuk Kandang Sapi

Abstract

The research was conducted 4 months from May-August 2022. The location is in Purwodadi Village, Kec. Maliku, Kab. Pulang Pisau, Central Kalimantan. The research objective was to analyze the effect of dolomite lime and cow manure treatment on the productivity of sweet corn. The tools used include hand tractors and pH meters. Bonanza variety corn seed, cow manure and dolomite are the ingredients. The research method used a randomized block design with 2 factors and 4 levels. The first factor of dolomite application is 4 levels: 0 ton ha^-1, 2 ton ha^-1, 4 ton ha^-1 and 6 ton ha^-1. The second factor was the dose of cow manure at 4 levels: 0 ton ha^-1, 15 ton ha^-1 , 20 ton ha^-1, 25 ton ha^-1. Variables observed: number of cobs (fruit), cob length (cm), cob diameter (cm), cob weight with husk (g), cob weight without husk (g) and harvest productivity (ton ha^-1). The results of the study found that the highest yield productivity was shown in the treatment of dolomite dose of 6 ha^-1 with cow manure dose of 25 ton ha^-1, the highest cob weight yield was 322.17 g plant^-1 with sweet corn production of 13.2 ton ha^-1.
