Investigation of sweet corn hybrids and the use of biopreparations in cultivation technology

Introduction. Intensive technology should be used in the production of sweet corn, since it is a vegetable crop and is much more demanding than ordinary corn. Modern cultivation of sweet corn requires compliance with a number of conditions associated with its biological characteristics, these are mainly the requirements of plants for heat, moisture, the level of nutrient content in the soil, etc.

The goal of the research. One of the important techniques in the development of cultivation technology for this crop is the selection of highly productive varieties suitable for cultivation in a particular area.

The objects and methods of the research. In our experiments, elite seeds approved for cultivation in the central part of the North Caucasus were used. Sweet corn hybrids were virtually identical in their growing season. Growing conditions have different effects on the growth and development of sweet corn plants.

The results and discussion. Germination and survival rates of three sweet corn hybrids: Caramello, Trophy, and Noah have been analyzed. At a seeding rate of 65 thousand viable seeds per hectare, Caramello has shown the best germination results, showing 62.5 thousand plants, which slightly exceeds the norm. Trophy and Noah also have demonstrated good germination at 61 thousand plants. The research, aimed at studying the effect of biopreparations on the growth, development of individual plant organs, and yield of sweet corn, has shown that one of the important factors affecting yield is the plant density, which determines the optimal nutritional area for each plant.

The conclusion. Our observations of seedling density and the number of plants at harvest have shown that biopreparations have a positive effect on plant survival.
