Abstract
The article gives the analysis of experimental date, obtained in the trials of ARRI of maize in the sufficiently moisturized region of Stavropol Kray in the years of 2005-2015. The object of study was the middle early maize hybrid ‘Mashuk 250SV’. During the plot-trials we studied the effect of the elements of cultivation technology (tillage, sowing term, density of stand, fertilizing, herbicides) on the productivity of hybrid grain. It has been established that the molding plowing on the depth of 22-25 cm in the autumn supplies the higher yield of grain, than the surface tillage (disc plowing) on 10-12 cm. The grain productivity reduced on 7.3% when the technology of plowing was changed from the moldboard treatment into the surface one. The pre-sowing fertilizing with N30 P30 K30 was the most efficient after the moldboard plowing than after the disc plowing. The grain productivity on the fertilized soil plowed with a moldboard was higher on 9.2% than on the soil plowed with a disc. The pre- sowing nitrogen fertilizing of N60 increased the grain productivity on 0.42t/ha. You can sow the hybrid in the period of 15-30 April, but the sowings in the middle of April give the greatest yield of grain. It has been determined that the best density of plant stand is 70.000 pieces per ha. To protect the yields from the weeds you can use the following postemergence herbicides: ‘MayesTer (0.15kg/ha), the grain productivity increase was 32.1%; ‘TitusPlus’ (0.35kg/ha), the grain productivity increase was 38.8%; ‘Kassius’ (0.04kg/ha) with Aminopelik’ (0.6 l/ha), the grain productivity increase was 33.8%.
