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.

Beli luk je ispitan u poljskim ogledima koji su izvedeni u centralnom delu Srbije (Beograd). Ispitan je beli luk proletnjak. Postavljen je cilj da se ispita uticaj gustine useva na produktivnost fotosinteze (LAR-Leaf Area Ratio, NAR-Net Assimilation Rate) i prinos belog luka. Ispitivanjima su bile obuhvaćene sledeće gustine useva: 300 (G1), 450 (G2), 600 (G3), 750 (G4) i 900 (G5) hiljada biljaka ha-1. Beli luk je ostvarivao bolje rezultate u gušćim usevima. Na to jasno ukazuje prinos koji je beli luk ostvarivao u ogledima. Prosečne vrednosti prinosa kreću se u rasponu od 5,6 (G1) do 12,5 t ha-1 (G5). Rezultati pokazuju da beli luk treba gajiti u usevima veće gustine.
