Uticaj vremena osnovne obrade i folijarne prihrane na prinos soje

Abstract

Visoki prinosi i stabilna proizvodnja soje pod direktnim su uticajem količine i rasporeda padavina, dostupnosti hraniva biljkama i pravovremenosti primene agrotehničkih mera. Cilj ovih istraživanja je ispitivanje uticaja vremena osnovne obrade i folijarne primene đubriva na visinu prinosa soje. Zimska osnovna obrada zemljišta smanjuje prinos soje u proseku za 4,07%, odnosno od 2,16% do 5,57% u različitim godinama, dok prolećna osnovna obrada smanjuje prinos za 11,20% (od 6,11% do 18,06%). Folijarna primena đubriva povećava prinos u proseku za 4,76%, a povećanje se kretalo od 1,27% pri jesenjoj osnovnoj obradi u 2020. godini do 8,40% pri prolećnoj osnovnoj obradi u 2019. godini.

High yields and stability of soybean production are directly affected by the amount and distribution of precipitation, available nutrients, and moment of agrotechnical measures application. This research aimed to examine the effect of primary tillage moment and foliar fertilization on soybean yield. Winter tillage reduced the soybean yield by 2.16% ̶5.57% in different years, 4.07% on average, while spring tillage reduced yield by 11.20% on average (6.11% ̶18.06%). Foliar fertilization increased yield by 4.76% on average, the increase ranged from 1.27% when autumn tillage was applied in 2020 to 8.40% when tillage was conducted in spring of 2019.
