Mathematical and statistical analyzes of the influence of Foliar fertilizers on the biometrics of common wheat
Keywords:
common wheat, foliar fertilizers, biometric indicators, correlation analysisAbstract
The purpose of the study is to analyze the impact of foliar fertilizer treatment on the productivity of common wheat. The field experiment was conducted in 2014-2016, in the conditions of meadow-cinnamon soil. One-factor dispersion analysis was performed; variants were evaluated by the Duncan test for multi-directional comparison. From the one-factor dispersion analysis carried out on the main biometric parameters and subsequent comparative analysis on Duncan, it is proved that the height of the plant is statistically very well documented. An additional Duncan test allows grouping of variants. The “length of the spike” of both varieties is distinguished as moderately high. The variation follows a trend for both varieties. In the first year, the coefficient of variation in Apolon and Bologna was 14.29% and 15.59% respectively, for the second one was 4.45% and 5.64% and for the last 5.53% and 5.17% respectively. Correlations between the quantitative indicators for the two varieties of common wheat have been established. There is a high, statistically proven correlation between the indicators: “length of the spike” (x2), “number of spikelets per spike” (x3) and “weight of grains per spike” (x4). The results of the correlation analysis are in line with the conclusions drawn from the analysis of applied irrigation regimes and their impact on plants from a biological point of view.
