Efficiency of foliar fertilization on wheat production in conventional and conservation agriculture

Abstract

The paper presents the leaves fertilization influence upon wheat yield in two experiments carried out in conventional agriculture and conservative systems. The experimental fields comprised 6 leaves fertilizers variants and a control and were laid out at SCDA Teleorman on a Haplic Phaeozem. Two treatments were applied with 1.25% leaves fertilizer on a N90P40K0 agrochemical background proceeded from a complex 20-20-0 fertilizer, in the autumn, before sowing, and 50 kg N/ha Nitrocalcar, applied in the spring. Leaves fertilization, applied in the conservative system experiment, didn’t bring forth a significant yield increase as compared to the control. Significant and distinctly significant increases of the wheat yield were obtained in the conventional agriculture system, from 5,795 kg/ha in the control up to 7,373 kg/ha in the Nutrifert S variant. The average conventional agriculture yield (6,978 kg/ha) was higher than the conservative agriculture one (5,457 kg/ha) by 27.8%.
