Influence of crops mineral nutrition on the biometric indicators of grain sorghum formation

The study of the elements grain sorghum cultivation technology, in particular, application mineral fertilizers, is one main promising tasks, which will contribute to formation high crop productivity. article shows results studies on effect various doses fertilizers growing season duration, feld germination and biometric indicators plants varieties Dniprovsky 39 Vinets Right-Bank Forest-Steppe Ukraine. were carried out 2016–2020 conditions Bila Tserkva Experimental Breeding Station Institute Bioenergy Crops Sugar Beet National Academy Sciences – zone It was found that use at a dose N30P30K30 N60P60K60 increased duration by 1–2 days compared control, N90P90K90 N120P120K120 2–3. At calculated shortest amounted 114 for variety 112 variety. greatest influence seeds years research exerted weather 27.1 % 13.2 %, degree much less 9.5 %. correlation-regression analysis reveal strong relationship between stem diameter plant height, as well leaf surface area height. with maximum (N90P90K90 N120P120K120) estimated (N50P40K70) received growth development plants, so it advisable apply below planned yield, reduce production costs. Key words: varieties, similarity, area.
