Abstract:

The aim of the study is optimization of nutrition system for soft spring wheat plants through the use of mineral fertilizers in order to obtain high quality grain with simultaneous yield increase. Different doses of mineral fertilizers were tested in the study. The object of study was a variety of soft spring wheat ‘Uliublena’. The structure of the crop was determined by the method of selecting sheaf samples from each accounting area. The leaf surface area was determined by calculation method. According to the results of research, yield capacity of soft spring wheat on average ranged from 2.43 to 4.51 t ha-1. The highest index of gluten amount was obtained in the variant with fertilizers dose N64P64K64 – 28.19%, which is higher than in the variants with fertilizer doses N16P16K16 and N32P32K32 by 6.11 and 0.15%. The highest increase in the yield of soft spring wheat grain (2.08 t ha-1) was obtained with application of N64P64K64, slightly lower yield increase was obtained with application of N32P32K32 – 1.64 t ha-1, and N16P16K16 – 0.99 t ha-1 comparing with the control. With fertilizer dose of N64P64K64 soft spring wheat provided the maximum yield – 4.51 t ha-1, gluten content – 28.19% and protein content – 14.21%.
