PERTUMBUHAN DAN HASIL BERBAGAI VARIETAS KACANG HIJAU ANTARA SISTEM MONOCROP DAN PENANAMAN BERSAMA PADI BERAS MERAH PADA SISTEM IRIGASI AEROBIK

Abstract

This study aimed to compare growth and yield components of various mungbean varieties between growing in monocrop and growing together with red rice in aerobic irrigation system, by carrying out pot experiment in a plastic house located in Dasan Tebu village of Kediri District, in West Lombok, from May to September 2017. The experiment was designed according to the Completely Randomized Design (CRD) with three replications and two treatment factors arranged factorially, namely mungbean varieties (varieties of No.129, Merak, Vima-3, Vima-1, and Kenari) and planting patterns (in monocrop and growing together with rice). Data were analyzed with analysis of variance (ANOVA) and Honestly Significant Difference test (Tukey’s HSD) at 5% level of significance using the statistical software CoStat for Windows ver. 6.303. The results showed that there were different responses between several mungbean varieties to growing it together with red rice in relation to growth and yield components of mungbean. The mungbean variety No.129 showed higher seed yields when grown together with red rice (11.78 g/pot), whereas seed yield of the Vima-1 variety was lower (i.e. only 6.5 g/pot) and lowest when grown together with red rice plants compared with growing on the monocrop system (9.32 g/pot), while the Vima-3 variety showed non-significant differences in seed yields between growing together with red rice (11.66 g/pot) and growing in monocrop systems (10.09 g/pot). Therefore field testing experiments are required to find more tolerant mungbean varieties for planting together with rice plants in an intercropping system.
