[Some elements of the agrobiological rationalization of production [winter wheat, barley]]
1986
Spaldon, E.
The polyfactorial field experiment which was carried out included 14 winter wheat varieties, 3 winter barley varieties, 2 sowing terms, a number of seeding rates and 4 doses of NPK fertilizers. The observation included: developmental stages, formation and reduction of yield elements, climatic conditions, health conditions, the achieved yield of grain and straw, the yield structure, the quantities of N, P, K, Ca and Mg carried out with the yield of grain and straw. On the basis of the obtained results a new understanding of the process of biological rationalization of wheat growing was established.
