Study of Growth and Production Test of Soybean Varieties on Shade Coconut Trees in Aceh

Abstract The conversion occurrence of agricultural land has a significant effect on the decline in soybean production, so that the use of coconut land with a double cropping system to increase national soybean production. Soybean cultivation in agroforestry systems can be applied to soybean cultivation systems under shade with shade-tolerant varieties. This study aims to determine the growth and yield of soybean varieties at various levels of shade of coconut trees. The research was carried out in Paru Keude Village, Bandar Baru District, Pidie Jaya Regency, Aceh, carried out in April – September 2019, with a Split Plot Design. The main plot is shade (N) consisting of no shade (N1), 25% shade (N2) and 50% shade (N3), and the variety plot (V) consists of Dena 1 (V1), Anjasmoro (V2) and Fan Red (V3). The study was analyzed by ANOVA, if the F value was greater than the value in the F table, it was continued with Duncan's Multiple Range Test at a significance level of 95%. The results showed that the Kipas Merah variety had higher plant height than Dena 1 and Anjasmoro, but Dena 1 had higher production at each shade level compared to Anjasmoro and Kipas Merah. Thus, the Dena 1 variety was able to maintain production at all shading conditions.
