The formation of spring wheat yield in Russia Central region as a function of productive stalks density

Abstract

There are some traits of spring wheat, that distinguish it from other cereals. Firstly, it’s the relatively slow growth rate on early stages of ontogenesis, which made spring wheat especially susceptible to the unfavorable environmental conditions. In agricultural conditions of the Central Region, the high positive correlation between spring wheat yield and number of productive stems per 1 m² was observed. This correlation proven to be stable by years. Because of that, any increase in yield per spike must correspond with the creation of new varieties with higher density of productive stalks.
