Uticaj zaoravanja žetvenih ostataka na povećanje prinosa soje

Abstract

Prinos soje zavisi od sorte, plodnosti zemljišta, agrotehničkih mera, kao i od vremenskih uslova u pojedinim godinama. Zaoravanjem žetvenih ostataka preduseva povećava se sadržaj organske materije u zemljištu, što ima pozitivan uticaj na plodnost zemljišta. Zaoravanje žetvenih ostataka preduseva kukuruza dovelo je do povećanja prinosa soje u proseku za 10,43%, odnosno po pojedinim godinama povećanje prinosa je bilo od 7,039% do 15,94%. Zaoravanje žetvenih ostataka preduseva kukuruza ima pozitivan efekat na povećanje prinosa soje i mora se posmatrati kao obavezna agrotehnička meru u gajenju soje.

Soybean yield depends on soybean variety, fertility of soil, agro-technical measures, as well as from weather conditions in certain years. Ploughing crop residues increases the content of organic matter in the soil, which has a positive effect on the fertility of the soil. Ploughing corn residue previous crop lead to an increase in yield of soybean on average by 10.43%, that is, by some years the yield increase was from 7.039% to 15.94%. Ploughing harvest residues previous crop of maize has a positive effect on the increase in yield of soybeans and must be considered as compulsory agro technical measure in soybean cultivation.
