Plant and Soil Science

Growing sugar corn in the Forest-Steppe zone for use in boiled form and for the processing industry is becoming increasingly important. One of the methods of continuous provision of the population with products and the processing industry with raw materials is the use of dates for sowing seeds. Purpoze.The aim of the study was to analyze the patterns of the passage of phenological phases of plant growth and development, to investigate the biometric indicators of hybrids of sugar corn depending on the timing of sowing seeds. Methods - the field, laboratory, statistical. Researches were conducted in 2017-2018 on cespititious-middling podzolic soils of north part of Forest-steppe of Ukraine in NDP the «Fruit and vegetable garden» in NUBiP of Ukraine. The studies studied the hybrids of foreign selection - Spirits F1, Overland F1, Svetastar F1 and sowing terms. The results of the research established that the growing season at a later date of sowing was reduced by 5-7 days. Between the length of the growing season and the duration of the interphase periods, a direct relationship is established - “seedlings - flowering of the panicle” - r = 0.66 and “seedlings - flowering swings” r = 0.79.
