Pengaruh Pemupukan Kalium dan Fosfat Terhadap Pertumbuhan dan Hasil Kedelai

TL;DRAbstract

ABSTRACT: This research purpose was to know the most accuration of potassium and phosphate rate due to get the best soybean yield. It was conducted in Ngepungrojo village, Pati district, Pati regency on August 18th to October 26th 2009. The experiment design that used is factorial based on Complete Random Design with 2 factors and 3 replications. The first factors are : The Potassium rate (K) consists of 3 levels : K1 : 100 kg KCl / hectar = 0,6 gr / plant; K2 : 150 kg KCl / hectar = 0,9 gr / plant ; K3 : 200kg KCl / hectar = 1,2 gr / plant. The second factor was Phosphate rate (P) consists of 3 levels. F1 : 150 kg TSP / hectar = 0,3 gr / plant; F2 : 100 kg TSP / hectar = 0,6 gr / plant F3 : 150 kg TSP / hectar = 0,9 gr /plant. It was found out from this research, that the potassium fertilizer affected significantly to the number of branches per plant with the number of highest branches on K1 is 3,1 per plant, the soybean seeds weight per plant with the highest yield of seed weight
