INFLUENCE OF THE SOIL AND THE CLIMATIC CONDITIONS OF THE FOOTHILL ZONE OF KABARDINO-BALKARIA ON THE PERFORMANCE INDICATORS OF SYMBIOTIC CROPS, YIELD, YIELD STRUCTURE AND THE QUALITY OF LENTIL SEEDS
In the leached black soils of the foothill zone of the Kabardino-Balkarian Republic on the territory of training experimental plant of FSBEI HE Kabardino-Balkarian state agricultural university named after V.M. Kokova we have studied the effect of soil and climatic conditions of area of ​​cultivation and application of micro - macro fertilizers, plant growth regulators and biological products on the crops of lentils, their impact on the efficiency and quality. It is proved that in general, the natural conditions of the foothill zone are favorable for cultivation and obtaining high yields of major crops. The analysis of meteorological conditions of the area (typical for the whole area) shows that there are great reserves and opportunities to obtain high and stable yields of lentils grains. These morphological, genetic and agrochemical parameters of leached chernozem growing zones suggest the soil favorable to the growth and development of lentils. On average, during the years of studies, the number of plants on which we had marked tubercles, on the example of Rauza varieties in the background variant, was 63.7%; the use of the drug called Agropon C in combination with sodium selenite increased by 15.2% the number of plants with root nodules. Increasing the number of plants with root nodules was accompanied with increasing the number and weight of nodules per plant by 8.1 pc. and 10.1 mg. respectively. The highest yield - 2.66 t/ha under experimental conditions was obtained in the form of joint use of the drug Agropon C and sodium selenite with a seeding rate of 2.2 million viable seeds per hectare, which is higher than the reference version for this seeding rate by 0.46 t/ha or 17.3%. The maximum value indicators of protein content in the seeds and collecting the protein per unit area reached with the use of joint application of Agropon C and sodium selenite, where we achieved the seeding rate of 2.2 million of germinating seeds per hectare and made up 29.6% and 787 kg/ha, respectively
