Uticaj gustine setve na neke morfološke osobine soje (Glycine max)

Abstract

Prinos i morfološke osobine soje zavise od sorte, plodnosti zemljišta, agrotehničkih mera, kao i od vremenskih uslova u pojedinim godinama. Cilj ovih istraživanja je da se sagleda uticaj različitih gustina setve na prinos, masu biljaka, visinu mahuna i broj kolenaca na stablu za tri različite sorte soje. Sorta Valjevka je najviši prinos ostvarila pri sklopu od 500000 biljaka, sorta Sava pri 450000 biljaka, a sorta Rubin pri sklopu od 400000 biljaka po hektaru. Povećanjem gustine useva kod sve tri sorte soje smanjuje se masa biljaka i povećava se visina prvih mahuna na stablu soje.

Yield and morphological traits of soybean depend on the variety, soil fertility, cultivation practice as well as the weather conditions in certain years. The aim of this research is to test the influence of different plant densities on yield, biomass, pod height and a number of mainstem nodes for three different soybean varieties. Variety Valjevka has achieved the highest yield with crop canopy of 500,000 plants, variety Sava at 450,000 plants and the variety Rubin with 400,000 plants per hectare. By increasing the density of crops the biomass is reduced and the first pod on the plant is higher in these three varieties.
