Keragaan Hasil dan Daya Toleransi Genotipe Kedelai di Lahan Sulfat Masam

Abstract

High soil acidity is one of the problems caused low soybean productivity on acid sulphate soil. Using tolerant variety is one effort for increasing soybean productivity on acid sulphate soil. The objective of theser esearchesw eret o understandt he performancey ield and tolerancy of soybeang enotypest o acid sulphate soil. Theser esearchesw ere conducted on acid sulphate soil at Pindahan Baru. Jajangkit Timur and Talaran-Barito Kuala District of South Kalimantan.i n wet seasono f 2003/04. Theser esearchesw ere arranged in RandomizedC ompletelyD esign with three replications.F ive genotypesa nd 4 varieties were evaluatedfo r their tolerance and yield potential. The result showed that none of the genotypes have yield higher than that of check varieties Lawit, Menyapa and Sibayak. There was one of genotypesi. e. Msc 9234-D-3 give higher yield than check varieties Tanggamusg, ood seedq uality and tolerant to acid sulphate soil.
