Essay

Object - peculiarities of growth and development of corn hybrids of different ripeness groups under the influence of sowing terms and plant density. Purpose - to ground theoretically and establish optimal structures of micro agroecosystems of new corn hybrids of different ripeness groups depending on the sowing terms and plant density. Methods - field and laboratory researches, statistical analysis. Results - the recommends technological measures provided the yield 81-85 centners per hectare of hybrids Kadr 267 MV and Dniprovsky 337 MV on the experiment plots. Novelti - for the first time in the conditions of the eastern part of Forest-Steppe of Ukraine optimal sowing terms and plant density of corn hybrids Kadr 195 SV, Kadr 267 MV, Dniprovsky 337 MV have determined. The results have been introduced in the enterprises of Poltava region on the area of 150 hectares. Sphere - agriculture.
