Evaluating the Performance of Three Mungbean (Vigna radiata, L.) Varieties Grown Under Varying Inter-row Spacing

Abstract

The study aimed to evaluate the agronomical traits and yield performances of three different mungbean varieties grown under varying inter-row spacing. A field trial was conducted to establish the proper inter-row spacing and appropriate variety evaluation under the agro-climatic condition of Agusan del Sur. Three mungbean varieties V1, V2, V3 (Wonder, Malagkit, Kalaya) were grown at three inter-row spacing (S1 - 40 cm, S2 - 50 cm, S3 - 60 cm) respectively. An experiment was set out in Split-Plot Design arranged in a Randomized Complete Block Design (RCBD), in which inter-row spacing as main plot (A) and varieties as the sub-plot (B). The data documented were analyzed statistically by means of Analysis of Variance (ANOVA) and Least Significant Difference (LSD) at 1% probability level. Inter-row spacing significantly influenced the nodules per plant, pods per plant, biological yield, seed yield, harvest index and shelling percentage. Likewise, the performance of varieties significantly differed in agronomical traits and yield performances of mungbean except on the nodules per plant. Moreover, a significant interaction effects between inter-row spacing and variety were observed only on the yield performances of mungbean; particularly in biological yield, seed yield, harvest index, and shelling percentage. Furthermore, it recommends in this study that the Kalaya variety of mungbean should be planted in a 50 cm inter-row spacing to achieve the best seed yield (kg/ha).
