Resumo


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.
