Increasing Yield of Vigna radiata(L.) cv. Chai Nat 72 with Suitable Sowing Spacing

Kiriya Sungthongwises and Wachira Sornpha

Abstract:
Background and Objective: Vigna radiata is the main source of protein for human consumption, characterized by the richness in minerals and vitamins. The increased competition caused in the denser populations has a direct effect on the yield capacity of the plants. This experiment compared the effect of three sowing spacing between plant space and row space (30×30, 25×50 and 50×50 cm) on the growth and yield components of V. radiata cv. Chai Nat 72. Materials and Methods: The seeds were drilled in a subplot size of 25 m2 at the early and end of rainy seasons. Thinning to two plants per hole was carried out by hand at 14 days after planting. The study was laid out in a Randomized Complete Block Design (RCBD) with four replications of across sites, using Statistics software, version 8.0. Results: The results showed that the highest plant height was observed in 50 and 30 cm row spacing respectively where plants were spaced 25 and 30 cm within rows respectively. A maximum number of seeds per pod, biological yield per plant, 100 seed weight biological yield and grain yield were recorded for row spacing of 30 cm where plants were spaced 30 cm within rows at the early of the rainy season. Conclusion: This experiment showed that higher plant density may affect individual plants’ access to light. However, light duration and light intensity are important factors at the flowering stage to decrease inflorescence number, fertility, pod numbers and grain yield.
