PENGARUH PEMBERIAN PUPUK KALIUM SULFAT DAN UNSUR HARA BESI (Fe), MOLIBDENUM (Mo) TERHADAP PERTUMBUHAN DAN PRODUKSI KACANG TANAH (Arachis hypogaea L.)
Abstract
This study aims to determine the effect of potassium sulfate fertilizer and nutrients Fe, Mo on the growth and production of peanuts. The study was conducted at Jalan Binjai km 10.5 with a height of 36 meters above sea level . This research was carried out starting in May to September 2013. In this study the method used is a randomized block design factorial consisting of 2 factors. The first factor is fertilizer Potassium Sulphate fertilizer consists of three levels namely: K1 = 12 g/plot , K2 = 24 g/plot , K3 = 36 g/plot. The second factor is the micro nutrients (Fe and Mo) consists of four levels, namely : M0 = (without micro-nutrients), M1 = 0.5 g/plot , M2 = 1.0 g/plot and M3 = 1.5 g / plot. The results showed that the treatment dose of potassium sulfate 36 g/plot is very real increase plant height, number of branches and number of ginofora. The treatment dose of micro-nutrients 1 g/plot is very real increase plant height, number of branches and number of ginofora. Interaction between potassium sulphate fertilizers and micronutrients dose Fe and Mo no significant effect on plant height, number of branches and number of ginofora
