Kobernyuk O. Development of soryz's growing technology elements in conditions of southern part of Western Forest-Steppe

In dissertation the results of researches of specialities of growing, development and training of photosynthetic and grain productivity of soryz depending on sorted special features, way and norm of sowing are set out, and also qualitative measures of grain are identified and the economic and bioenergetic evaluation of soryz's growing technology elements in conditions of southern part of Western Forest-Steppe are stated. It is researched, that the increase of seeds sowing norm from 200000 to 300000 pieces per hectare of similar seeds promotes the decrease of vegetation period by 3-8 days. It is stated, that the highest crop capacity of soryz emerges in usual drill sowing (15 cm.): by sowing norm of 200000 pieces per hectare of similar seeds - 7,91-8,47 ton per hectare, 250000 pieces per hectare - 8,35-8,89 ton per hectare, 300000 pieces per hectare of similar seeds - 8,87-9,43 ton per hectare. The given research results about influence of way and norm of sowing on quality of soryz's seeds. The content of starch in seeds is 65,17-70,62 %, the content of protein - 12,11-14,75 % depending on sort. Based on materials of field and on-the-farm researches, and their economic and bioenergetic analysis, by agricultural formation of the region was recommended to sow the sort of soryz Odeskyi 302 in drill sowing (15 cm.) with the sowing norm of seeds 300000 per hectare of similar seeds, that ensures the profitability level by 174,4 % and energetic efficiency factor by 5,72.
