KAJIAN PEMBERIAN PUPUK P, PUPUK MIKRO DAN PUPUK ORGANIK TERHADAP SERAPAN P DAN HASIL KEDELAI (Glycine max L.) VARIETAS KABA DI INSEPTISOL GUNUNG GAJAH KLATEN

Abstract

Research purposes to determine the response of soybean varieties Kaba under protected forest tree stands besides soybean crop response to P fertilizer and manure fertilizer micro coupled with organic fertilizer uptake and utilization of P element to the low light under protected forest tree stands. The research was conducted in JulyDecember 2011. Experiments using Randomized Complete (RAKL) factorial consists of 3 factors, namely fertilization with manure P 1, factor 2 micro fertilization with manure, and a factor of 3 fertilizing with organic fertilizers. Each treatment combination was repeated 3 kali.Faktor first fertilizer P fertilizer P The first factor consists of three levels, namely P1 (50 kg / ha), P2 (75 kg / ha), and P3 (100 kg / ha). The second factor consists of 2 fertilizer micro level, ie M1 (0.5 l / ha) and M2 (1.5 l / ha). The third factor of organic fertilizer consisting of 2 levels, ie O0 (0 tonnes / ha) and O1 (5 tonnes / ha). Data analysis using the F test level of 5% followed by comparison test (DMRT) level of 5%. The results show the interaction between P fertilizer, micro fertilizer and organic fertilizer effect on soil pH, P uptake, and the number of pods. P fertilizer on fertilizer and organic fertilizer micro effects and no significant effect on available P and heavy pod soybeans (Glycine max L.).
