Effect of mineral fertilizer rate on biometric indicators of soft wheat varieties

In this article, it is presented an analysis of data obtained on the impact of growth, development, stem height, spike parameters, grain yield and mineral fertilizer application norms on its quality indicators in soft wheat varieties. In the experiment, the increase in the rate of mineral fertilizers did not affect the increase in grain size, but rather its decrease. In particular, the highest yield was achieved when the feeding norm NPK 200:150:100 kg/ha was applied, but when determining the amount of grain formed at the expense of 1 kg NPK, it was 13.62-15.33-14.15 kg by varieties. Grain quality indicators are the highest in the variants applied NPK 200:150: 100 kg / ha, protein (15.0%), gluten (28.6%) and vitreous (63.9%) of the variety "Shavkat", control "Hosildor" (13.5%; 26.3%; 60.6%) and “Turon” (14.0%; 27.8%; 59.7%).
