Modeling on the Seed Yield of Mungbean (Vigna radiata, L.) Using Its Agronomical Traits

Abstract

Three mungbean varieties were studied for association of seed yield per plant with some important agronomical traits such as plant height, nodules per plant, branches per plant, pods per plant, and seeds per pod. A field trial was conducted for the three varieties V1, V2, V3 (Wonder, Malagkit, Kalaya) that were grown on a sandy clay loam soil during wet season. Experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications using the net plot size of 24m x 7.5m. In order to build the model for seed yield, the data recorded were analyzed statistically using multiple linear regression analysis. Seed yield per plant showed a positively significant association with pods per plant and seeds per pod. Meanwhile, plant height has a negatively significant association to seed yield per plant. However, the identified two independent variables accounted for 62.20% of the total variation in modeling the seed yield of mungbean were nodules per plant and pods per plant that showed an impact among three different varieties. Thus, it is recommended in the study that lesser number of nodules with greater number of pods per plant to be used as a selection criteria for developing high yielding mungbean varieties. Moreover, future researchers may also consider other factors in developing the model of the seed yield of mungbean such as the phenological attributes; i.e. days to flowering, days to podding and seed filling period.
