Tehnologyc methods of the optimize growing hybrid corn and sweet corn maize - sowing, plant density, the dose of fertilizer. Subject of research. Early maturing gybrid Dniprovskyi 181 SW, 274 SW a mid Podolsky, mid Monica 350 mV, medium Sokolov 407 ST. Research methods. The main methods are field, laboratory - field studies, the method matimaticheskoy data. Objective. Develop for oroshaemyz conditions of Crimea basic techniques varietal farming new hybrids of grain and corn belonging to different maturity groups to recommend the optimum production parameters of their growth. Results. In terms of optimal utilization of production and natural resourses and achieve maximum economic efficiency in irrigation zone of Crimea is most advisable to sow maize on 30 April, adding mineral fertilizers to the dose N120P90 and optimal stand density for early-ripe hybrid Dniprovskyi 181 NE - 80 thousand ha of plants, grain yield was 7.49 tons per hectare, the conditional net profit - UAH 6,130.3 / ha, a mid Podolsky, 274 NE - 70 thousand ha, productivity of land is 8.58 tons per hectare, profit - 6467.0, mid Monica 350 MV - 60 thousand per hectare yield - 8.42 tons per hectare, profit 6,085.3 USD / ha, 407 medium-Sokolov SV - 50 thousand per hectare yield - 8.24 tons per hectare, profit 5,672.7 UAH / ha. Gybrid corn Surprise to sow April 20 when making the dose of fertilizers N120P90, the yield of ears in wrappers 12.33 t / ha, cobs without wrappers - 10.29 t / ha, conditioned ears - 8.33 t / ha, substandard - 1 96 t / ha. In order to stabilize grain production in the irrigation zone of the Crimea advisable to grow early maturing hybrid Dniprovskyi 181 MW (minimum cost of growing and the lowest grain moisture), a mid Podolsky, 274 SW (high level of profitability and maximum profit). Implementation of the technology of growing corn on an area of 15 hectares Testing and introduction into production. Corn hybrids, planting dates, plant density, the dose of fertilizer.
