Among cereals, wheat is very sensitive to nutrient supply, especially to nitrogen. The objective of our study was to determine optimal rates and dates of nitrogen fertilization on the background of P60Ę60 for Spelt ( Zarya Ukrainy variety) on podzolic heavy loam chernozem in the Right Bank Forest Steppe (Ukraine). Phosphorus and potassium fertilizers were applied during the basic soil tillage, while nitrogen fertilizers (at doses of 30, 60, 90, 120 kg/ha)– in autumn during presowing cultivation, as additional fertilization in spring, at the tillering stage and at the stemextension stage. Also, foliar fertilization using carbamide solution was performed. Spelt plants responded well to the improved nitrogen nutrition, resulting in the increase of protein and gluten content by 30-70% depending on the rates and dates of nitrogen fertilization. The highest protein content was obtained in the variant Background N60 N30 N30 N30 foliar fertilization where, in the aggregate, 150 kg/ha of nitrogen were applied - by 447 kg/ha or 167% more compared to the control variant. Foliar fertilization helped to increase the protein content on average by 41 kg/ha or 16%. |
