Influence of Mineral Fertiliser and Foliar Dressing Rates on Buckwheat Yield

A significant problem in the cultivation of buckwheat is its low yield, therefore, it relevant to improve elements technology for growing this crop. The purpose study was establish optimal norms and terms applying mineral fertilisers foliar dressing with chelated microfertilisers forest-steppe conditions Western Ukraine, a zone sufficient moisture obtain stable high yields grain. For purpose, two-factor experiment conducted on experimental fields Lviv National Agrarian University dark grey podzolized light loamy soil, which included fertiliser rates: N20P20K20, P20K20+N20 (foliar dressing), N40P40K40, P40K40+N40 N60P60K60, P60K60+N60 dressing) dressing: control (without Vuksal Boron 2.0 l/ha, Intermag Legumes l/ha. Research methods: field studies – determine interaction object research weather factors system; calculation weight setting parameters crop structure indicators determining yield; methods mathematical statistics dispersion, correlation, regressive graphical display findings. An increase rates from N20P20K20 N60P60K60 provided an all structure. Without dressing, they reached following values: number first-order branches 1.56 pcs./plant, inflorescences flowers 10.68 1,011 pcs, respectively, full-size undeveloped grains (pcs./plant) 41.23 11.37, 1.15 g 1,000 28.00 g. introduction nitrogen (at beginning flowering) has advantages over pre-sowing cultivation. One proofs assumption grains, their weight, 35.43 pcs., 0.97 g, 27.37 (variant N40P40K40) up 37.27 1.03 27.80 P40K40+N40). This trend typical designs. positive effect observed. use 2 l/ha more effective. maximum variant + 1.21 while similar background indicator at level 1.17 Studies have established application by during flowering yield level, also increased rate under influence microfertilisers. average three years obtained 2.64 t/ha
