Efekat folijarnih tretmana na prinos soje

Abstract

Zemljište je glavni izvor hraniva za gajene biljke, ali i folijarna prihrana može pozitivno uticati na prinos i kvalitet poljoprivrednih proizvoda. U trogodišnjim istraživanjima prouĉavan je uticaj folijarnih tretmana na prinos soje. Rezultati su obraĊeni analizom varijanse i dobijene su statistiĉki veoma znaĉajne razlike između tretmana. U odnosu na netretiranu varijantu ogleda, folijarna primena 2% rastvora uree povećala je prinos u proseku 8,70%, dok je primena otopine koprive i gaveza povećala prinos soje za 8,07%. U odnosu na varijantu sa folijarnom primenom vode 2% rastvor uree povećava prinos za 6,73%, primena otopine i koprive i gaveza za 6,11%, dok je tretman sa vodom povećao prinos za 1,85% u odnosu na varijantu ogleda bez folijarnog tretmana.

Soil is the main source of nutrients for cultivated plants, but also foliar conservation can positively affect the yield and quality of agricultural products. In three years of research, the effect of foliar treatment on soybean yield was studied. The results were analysed by variance analysis and statistically significant differences were obtained between treatments. In comparison to the untreated variant of the experiment, foliar application of 2% urea solution increased the yield by an average of 8.70%, while the application of the nettle and common comfrey increased the soya bean yield by 8.07%. In relation to the variant with foliar application of water, a 2% solution of urea increases the yield by 6.73%, the use of solutions, nettle and common comfrey increases the yield by 6.11%, while the treatment with water increased the yield by 1.85% related to the variant of the experiment without foliar treatment.
