Effect of plant density on photosynthesis productivity and yield of spring garlic

Abstract

Garlic was examined in field experiments conducted in central Serbia (Belgrade). Spring garlic was examined. The objective was to examine the effect of plant density on photosynthesis productivity (LAR-Leaf Area Ratio, NAR-Net Assimilation Rate) and the yield of garlic. The analysis involved the following plant densities: 300 (G1), 450 (G2), 600 (G3), 750 (G4) and 900 (G5) thousand plants ha-1. The garlic exhibited better results in denser crop establishment. It is clearly indicated by the yield of garlic attained in the experiments. Average yield rates range from 5.6 (G1) to 12.5 t ha-1 (G5). The results demonstrate that the garlic should be grown in high density establishment.
