- ABSTRACT Lutfi Nizar Sunarya. 2021. Effect of Concentration of Growth Regulatory Substance GA3 and Dosage of Goat Manure on Growth and Yield of Long Bean (Vigna sinensis L.). Guided by Rusmana and Nuniek Hermita. Research was aimed to know the effect of ZPT GA3 concentration and dose of goat manure on the growth and yield of long bean (Vigna sinensis L.). Carried out from April to July 2021 in the experimental field of the Faculty of Agriculture, Sultan Ageng Tirtayasa University. This research used a factorial randomized block design consisting of two factors, the first factor was the level of ZPT GA3 concentration consisting of three levels, g1 (GA3 concentration 100 ppm), g2 (GA3 concentration 150 ppm), and g3 (GA3 concentration 200 ppm). The second factor was the dose of goat manure consisting of three levels, namely, p1 (10 tons/ha), p2 (20 tons/ha), and p3 (30 tons/ha). The results showed that giving 100 ppm GA3 had a significant effect on the parameters of the number of leaves of the long bean plant 2 WAP and a very significant effect on the parameter of the plant height of the long bean 2 WAP. The application of goat manure fertilizer at 20 tons/ha had no significant effect on all parameters of long bean plant observations. However, the dose of goat dung fertilizer of 30 tons/ha gave a significant effect on the parameters of long bean plant height 3&4 WAP and plant fresh weight and gave a very significant effect on the parameters of plant height 2 WAP and leaf number 4 WAP. There was an interaction of treatme nt with growth regulator GA3 and goat manure on the number of leaves at 3, 4, and 5 WAP. Keywords : GA3, Goat manure, Long bean
