Influence of meliorative application of fertilizers on grain yield and quality in spring sowing small grains on acid soil

Abstract

In the present paper it was carried out an investigation of influence of meliorative application of fertilizers on grain yield, mass of hectoliter and 1000 kernel weight in some varieties of spring wheat, spring barley and spring oat, grown on acid soil. Small grains demonstrated different reaction on increased acidity of soil. Oat varieties were significantly more tolerant and achieved acceptable grain yield compared to spring barley and wheat varieties, that on such soil could be grown only with previous liming. Meliorative application of fertilizers increased the grain yield of wheat by 2.7 times, in barley by near 4 times and in oat by about 2.5 times in average for all varieties and treatments. The best results were achieved by joint application of NPK, lime and manure. .
