The Effect of Time Shoulder (Topping) toward Growth and Results of Chocolate Seeds in Shadowing Conditions

This study aims to determine the effect of shoots of some brown soybean strains on shading stress conditions on growth and yield. The study was conducted in December 2018 - March 2019 Sekarbela District, Mataram. The experiment used a completely randomized two-factor design (CRD). Factor 1 is the strain (G) consisting of G1 = KH9, G2 = KH14, G3 = KH1 G4 = Dena, G5 = Anjasmoro. Factor 2 is the prune time (T) consisting of T1 = without pruning, T2 = pruning 3 MST, T3 = pruning 4 MST, T5 = pruning 5 MST and T5 = pruning 6 MST. The results showed that the KH14 brown soybean strain had better growth characters compared to the KH9, KH1 and yellow Dena and Anjasmoro varieties of soybean. The brown KH1 soybean strain showed high yields and components such as the weight of 100 seeds and the weight of the seeds of the plantings which was higher than other strains. Prune time affects the character of growth and yield of soybean plants. Prune time 3 MST showed the highest character of growth (plant height, number of productive branches, number of books), as well as yields and the highest yield components did not differ with the age of pruning 5 MST. There was no interaction between the prune time factor and soybean strain on the growth character and soybean yield
