Improving technology of eincorn cultivation in the central part of the North Caucasus

Abstract

In production technology to create a highly productive sowing of grain crops, careful regulation of numerous factors that determine the formation of a high yield is required. In various soil and climatic conditions of crop cultivation optimization of technological methods determine the crop size and its quality indicators. Therefore, in order to achieve the highest yield, it is necessary to create conditions for growth and development, under which the largest number of productive stems with the maximum grain mass should be preserved until harvest [1, 8, 13].The yield of the studied variety of Yarovaya spring eincorn is directly dependent on the satisfaction of crops with mineral nutrition elements. The level of efficiency of mineral fertilizers is increased by optimizing the timing of sowing and the selected predecessor.Optimization of mineral nutrition makes it possible to increase the yield of this crop by an average of 16.1%. The early sowing of eincorn after the predecessors of peas and corn for silage makes it possible to maintain the optimal number of productive stems of more than 4.6 million. plants per hectare with the highest grain weight per plant.At the same time, the interaction of the number of plants and different levels of mineral nutrition has led to a significant change in the quantitative indicators of eincorn productivity by changing the mass of grain from one plant, which significantly increases the yield to 2.87 t/ha, which is 200% higher than the worst case and 67% higher than the control variant in our studies.The introduction of mineral fertilizers does not have a great effect on the content of spikelets in the ear, while it has an effect on the quality indicators and the physical weight of the grain in the ear. The weight of seeds from 1 productive ear when mineral fertilizers are applied reaches 0.8 g compared to the control variant.With an early sowing period with a predecessor of peas and corn for silage, the efficiency of mineral fertilizers increases.
