Ischenko V. Optimization technology elements of growing varieties of peas of moustached type in the northern Steppe of Ukraine

The subject of the investigation – the optimization of the processes of growth, development and formation of the productivity of sorts of pea of the semileafless mustached type according to the application of fertilizers, the growth regulator and the biologics. The aim was to optimize the elements of the technology of growth of sorts of pea of the semileafless mustached type by means of the complex application of the biologic, microfertilizers, growth regulator and to set the most effective doze of mineral fertilizers on the background of the presowing inoculation of seed by the biologics of the nitrogen-fixing and phosphorus mobilizing action on the usual black soils of the North Steppe of Ukraine. Methods – field tests, the methods of the hypothesis, the synthesis, the analysis, measurement and weight, biochemical, of the mathematical statistics and economical methods. Results: it was optimized the technology of growth of pea of the semileafless mustached type which provides the formation of the productivity on the level of 2,87-3,55 t/ha in the conditions of the Steppe. The production test and implementation of the results of the investigation was performed in the State enterprise “The Experimental Farm of the Kirovograd institute of AIP of NAAS” and other enterprises of the Kirovograd region on area of more than 500 ha. Novelty – for the first time in the conditions of the North Steppe was proved the expediency of the complex use of the biologic of the nitrogen-fixing action of rizogumin with the growth regulator of emistim C and the microfertilizer reakom and also was established the effectiveness of the application of biologics of nitrogen-fixing and phosphorus mobilizing action on different backgrounds of mineral nutrition. It was optimized the technology of growth of pea of Kharkov standard and Tsarevich. It was substantiated the economical expediency of the recommended methods. Area – agriculture.
