Abstract

The study aimed to determine the optimal population density for mung bean crop by defining row spacing, and number of plants per meter. The experimental design was a randomized block with treatments arranged in a split-plot scheme with four replications. Two row spacings (25 and 50 cm) were allocated in the plots, and six number of plants per meter (4, 8, 12, 16, 20, and 24 plants) were allocated in the subplots. The experimental units had 4.0 m long, and 2.5 m wide, with 4.0 m2 of useful area. In the useful area of plot, plant height, stem diameter, number of pods per plot, pod length, pod width, number of grains per pod, 100-pods weight, 100-grains weight, final plant population, and grain yield were evaluated. Plant height, pod length, pod width, number of grains per pod, and 100-pod weight were not influenced by row spacing and number of plants per meter. There was influence of significant interaction between the factors studied on 100-grains weight and final plant population. There was a significant effect only of number of plants per meter on stem diameter, number of pods per plot, and grain yield. The row spacing of 50 cm and 24 plants per meter increased mung bean grain yield, revealing itself as a strategy of gain in the grain yield of the crop.

Highlights

Legumes are the main source of protein for human consumption, characterized by the richness in minerals and vitamins (Choudhary et al, 2017)
Pod length, pod width, number of grains per pod, and 100pod weight were not influenced by row spacing and number of plants per meter
Results from Bezerra et al (2008) corroborate those found by Nunes et al (2017), who, using the row spacing of 50 cm and evaluating different densities of cowpea plants, found that increasing plant density increases grain weight

Summary

Introduction

Legumes are the main source of protein for human consumption, characterized by the richness in minerals and vitamins (Choudhary et al, 2017). Between the highest-yielding legumes in the world, stands out mung bean Mung beans have two planting seasons due to their short cycle (Pratap et al, 2014). Its short growing period allows it to adapt to many cropping systems, which become adjusted at crop rotations, providing diversification in cropping systems. The species can be adopted in many production systems because besides increasing the income of small farmers, it provides significant improvements in soil fertility. Given its short growing period, low production cost, and adaptability in a wide range of soil and climate conditions, the growth of this crop is favored in different regions (Pratap et al, 2013)
