Abstract

The aim of this research is to determine the growth response and yield of several Black Soybean varieties in several variations of spacing. The experiment is a factorial experiment using a randomized block design consisting of two treatment factors, The first factor is the variety consisting of 3 levels: V1 = Detam 1, V2 = Detam 3 Prida, V3 = Detam 4 Prida. The second factor is spacing which consists of 3 levels: J1 = 20 x 20 cm, J2 = 20 x 30 cm, J3 = 20 x 40 cm. The interaction of varieties with plant spacing has a very significant effect on crop dry weight and seed oven per planting hole. Significant effect the yield seeds of dried and oven per hectare. The weight of oven dry seeds per planting hole and the highest yield of oven dried seeds per hectare was obtained in the interaction of Detam 1 varieties with spacing of 20 x 40 cm with was 33.79 g and 2.53 tons per hectare which increased 138.79% and 42.93% compared with the interaction of Detam 4 prida varieties with spacing of 20 x 20 cm with was 14.15 g and 1.77 tons per hectare.
