EFFECT OF NEW CaCO3 FORMULATION ON CORN COBS

Providing nutrition is a key factor in plant growth and development. Among the basic nutrients is calcium, in the form of ions (Ca2+). In the present research, it was observed how the new formulations of this macroelement demonstrate the achievement of positive effects. From the conducted research it emerged that the production of cobs increased between 12 and 33% and the grain yield remained constant. Against the background of calcium fertilization, the cobs showed insignificant lengths between 19 and 22 cm. At the same time, an increase in grain production was found between 10-30% and the absolute grain weight (MTG) was generally higher than that of the control. Crude protein (PB%) in grains was between 9-12% with slight increases. The other quality elements showed slight decreases in the case of starch content, while the oil fell within insignificant parameters. Among the correlations obtained between the studied characters, negative values were noted between cob production and grain yield (r = -0.58), between grain yield and crude protein (PB%) (r = -0.810) and between the production of grain and oil content (r = -0.026). Positive correlations were obtained between cob production and mass of one thousand grains (MTG) (r = 0.882), between grain production and mass of one thousand grains (r = 0.828) and between grain production and grain moisture (r = 0.329). As a result of the research carried out, it was found that positive effects were obtained through liming the corn crop, which recommends the use of new formulations in production conditions.
