Uticaj navodnjavanja na prinos i kvalitet soje u 2021. godini

Abstract

Navodnjavanje je agrotehnička mera koja doprinosi stabilnosti i sigurnosti biljne proizvodnje, u uslovima klimatskih promena kojima smo izloženi poslednjih decenija. U 2021. godini sa izraženim sušnim periodom povećanje prinosa soje kretalo se kod različitih sorti u intervalu od 33% do 51%, sadržaj proteina je smanjen u intervalu od 1,8% do 4,7%, sadržaj ulja povećan u intervalu od 2,5% do 5,5%, dok je prinos proteina povećan u intervalu od 27,1% do 46,4%, a prinos ulja u intervalu od 40,7% do 58,1%. Cilj ovoga rada je sagledavanje prinosa, sadržaja proteina i ulja, kao i prinosa proteina i ulja po jedinici površine četiri NS sorte soje u uslovima suvog ratarenja i navodnjavanja u 2021. godini.

Irrigation is an agro technical measure that contributes to the stability and safety of plant production, in the conditions of climate change that we have been exposed to in recent decades. In 2021, with a pronounced dry period, the increase in soybean yield ranged from 33% to 51% in different varieties, the protein content decreased in the range from 1.8% to 4.7%, the oil content increased in the range of 2, 5% to 5.5%, while the protein yield increased in the interval from 27.1% to 46.4%, and the oil yield in the interval from 40.7% to 58.1%.The aim of this work is to analyze the yield, protein and oil content, as well as protein and oil yield per unit area of four NS soybean varieties under dry land and irrigation conditions in 2021.
