PENGARUH SISTEM OLAH TANAH DAN PUPUK P TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN KEDELAI (Glycine max L. Merril)

Abstract

Abstract

This study uses the draft Separated Compartments (RPT) with two factors studied were: tillage system (T) as the main plot consists of 3 levels, namely: T0 = no-tillage (control) T1 = T2 = minimum tillage tillage perfect fertilizer phosphate (P) as a subplot consisting of 4 levels, namely: P0 = 0 g / plot (control) P1 = 20 g / plot P2 = 40 g / plot P3 = 60 g / plot. From the results of the research analyzed statistics indicate that tillage systems and phosphate gives a significantly different effect, while the interaction between the two treatments showed no significantly different effect. The results of the statistical analysis that both tillage treatments and phosphate fertilizer showed no significantly different effect on the number of primary branches plant soybeans, as well as the interaction of these two treatments also showed that the effect was not significantly different. Based on the results of the statistical analysis of the data began flowering plant life observation that treatment of soybean tillage systems and fertilizer phosphate showed no significantly different effect. Interaction of tillage system and fertilizer phosphates also showed that the effect was not significantly different. Based on the results of the statistical analysis of the widespread observation that treatment of soybean leaves tillage system and fertilizer phosphate showed no significantly different effect. Further interaction between tillage systems and fertilizer phosphate showed no significantly different effect. From the results of the statistical analysis of number of pods per plant soybeans showed that tillage system treatment effect is not significantly different, but the phosphate fertilizer gives a significantly different effect on the number of pods per plant contain soy. Interaction of the two treatments showed no significantly different effect. From the results of the statistical analysis, both treamnet tillage system and fertilizer phosphate showed no significantly different effect, eventhought the interaction between tillage system and fertilizer phosphate to the observation variables dry weight per plant soy beans
