| dc.description.abstract | The aim of the conducted study, based on two-factor analysis of variance, is to assess the significance and power of influence of factors – treatment of the soil and fertilization and their interaction on the productivity of wheat. Data for the yield of irrigated corn were used, which were derived from field trial to study the effect of the treatment of the soil and fertilization on the yield of irrigated grain maize. The experiment was carried out in the experimental field of Agricultural Institute - Stara Zagora during 2009 - 2011 period. The result, by ANOVA method were proven statistically with significant variance of the factor “system of fertilization” (B) on "yield irrigated corn for grain”. | sr |
