Abstract

AbstractThis 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 beansKeyword: influence of tillage systems, phosphate fertilizer, Glycine max L.

Abstract

AbstractResponse of growth and production in peanuts (Arachis hypogae) on seed spacing and origin of the pods have been investigated. The study was designed according to the Random Design (RAK) factorial with two factors studied. Jark cropping factor as the first treatment factors. Spacing factor (J) consists of two levels, namely J1 = 30cm x 20cm, 30cm x 30cm = J2, J3 = 20cm x 20cm. While the origin of seed treatment factors on pod (P) consists of three levels, namely P1 (1per plor seed pods), P2 (second seed pods per plot), P3 (third seed pods per plot). The entire unit test in repeated sebamyak 3 times. Parameter observations used in this study include plant height, number of primary branches, number of empty pods per plant, production per plot, weight of wet pods per plant, dry weight of pods per plant and number of seeds per pod. Based on the observations and the origin of seed spacing on pod gives a significantly different effect parameters plant height, number of primary branches, number of empty pods per plant, production per plot, the wet weight of pods per plant, and dry weight of pods per plant. While the parameters of the number of seeds per pod were not significantly different.Keywords: Peanut, seed spacing, origin of the pods
