Respon Beberapa Varietas Kedelai Pada Beberapa Macam Sumber Kalium

Abstract

The study aims to determine the response of several soybean varieties to several types of potassium fertilizer. The study was conducted in March to June 2017 at the Educational and Experimental Garden of Institut Pertanian Stiper, Maguwoharjo, Depok, Sleman, Yogyakarta. The study used an experimental design with a completely randomized design. The first factor is the soybean variety which consists of three types namely Wilis, Kaba, and Gema. The second factor is the type of potassium fertilizer which consists of three types namely KCl, KNO3, and MKP. Data were analyzed using analysis of variance at 5% level. If there is a difference, the test is continued with DMRT. The results showed that there were interactions between various soybean varieties and various kinds of K fertilizer on growth and yield of soybeans.Wilis variety showed the best growth on KCL and Kaba and Gema variety showed the best growth on MKP. Wilis and Kaba variety showed the best yield on MKP and Gema variety showed the best yield on KNO3.
