Abstract

The mung bean (Vigna radiata L.) is a legume of food and forage importance and its potential as a cover crop. However, the limited availability of quality seed limits its use, which makes it necessary to evaluate management practices such as planting density. The objective of this study was to evaluate the effect of two densities (D1: 375,000 and D2: 185,500 plants ha-1) on yield, seed physical characteristics and physiological quality under rainfed conditions. The experiment was set up in a completely randomized design with four replications (Tukey; α = 0.05). The results showed that the plant height did not vary between treatments (57-63 cm), as did the weight of 100 seeds (6.5-6.6 g) and the morphometry of the seed (length 5.59-5.61 mm, width 4.13-4.15 mm, thickness 4.14-4.20 mm). In contrast, individual yield per plant was 75 % higher in D2 (3.5 vs. 2.0 g plant-1; p = 0.0005), with increases in pod length (95.4 vs. 90.3 mm) and number of seeds per pod (11.8 vs. 10.3). However, the yield per area was higher in D1 (783 vs. 646 kg ha-1; p = 0.0136). Germination (96 and 95 %) and emergence (86 and 84 %) did not show significant differences between treatments. These results confirm that the sowing density did not alter the morphometry or physiological quality of the seed, but it did determine the balance between individual and population yield.
