Jesenja i prolećna primena NPK đubriva u proizvodnji soje

Abstract

Intenzivna biljna proizvodnja podrazumeva pravilnu i pravovremenu primenu svih agrotehničkih mera, primenu đubriva na osnovu analize zemljišta, dopunsku ishranu sa mikroelementima i stimulatorima rasta, kompleksnu zaštitu protiv korova, bolesti i štetočina, u cilju ostvarivanja visokih i stabilnih prinosa, visokog kvaliteta. Još uvek se na mnogim parcelama u proizvodnji soje primenjuje prolećna primena NPK đubriva, pa je i cilj ovoga rada sagledavanje uticaja jesenje i prolećne primene NPK đubriva na prinos soje. Jesenja primena NPK đubriva statistički veoma značajno povećava prinos soje u odnosu na kontrolnu varijantu ogleda - bez đubrenja, ali i u odnosu na prolećnu primenu NPK đubriva.

Intensive plant production indicates proper and timely application ofall agrotechnical measures, application of fertilizers based on soil analysis, additional nutrition with microelements and growth stimulators,complex protection against weeds, diseases and pests, in order to achievehigh and stable yields, high quality. Spring application of NPK fertilizersis still applied on many plots in soybean production, so the aim of thispaper is to consider the influence of autumn and spring application ofNPK fertilizers on soybean yield. Autumn application of NPK fertilizersstatistically significantly increases the soybean yield in relation to thecontrol variant of the experiment - without fertilization, but also inrelation to the spring application of NPK fertilizers.
