Rehabilitasi Lahan Kering Alang – Alang dengan Olah Tanah dan Amandemen Kapur terhadap Pertumbuhan dan Produksi Tanaman Jagung

Abstract

The purpose of the research was to analyzed rehabilitation of crabgrass dry land with tillage and calcic amendment on growth and production of corn. The research was conducted at Juli Subsdistrict, Bireuen Regency, Aceh Province in January - Maret 2014 using factorial split pot design with two factor which consist of main plot is tillage (notillage, minimum tillage and maximum tillage) and subplot is calcification (nocalcification 0 ton/ha, calcification 1 ton/ha and calcification 2 ton/ha). Parameters measured were weight of soil volume, weight of soil particles, soil porosity, soil pH, soil capacity exchange cation, N total, available P, exchange K, Ca, Mg, height of corn at 15, 30 and 45 day after planting, fresh weight, cab height and 1000 seed weight of dry shelled. The result showed that tillage were affected significantly on weight of soil volume, weight of soil particles, soil pH, soil capacity exchange cation, N total, available P, exchange K, Ca, Mg, height of corn at 15 and 45 days after planting, but not affected significantly on the other parameters. Calcification were affected significantly on soil pH, soil capacity exchange cation, N total, available P, exchange K, Ca, Mg, but not affected significantly on the other parameters.
