Evaluation of the spring wheat crops development on the base of experimental phenological observations

Abstract

The results of four-year researches concerning influence of cenotic
factors such as (way of sowing and sowing rates) on the duration of
separate development phases of hard spring wheat plants are given.
The influence of a cenotic factor characterized by different
variations of experimental factors during the interphase periods in
plants’ development has been proved in the experiments. Under weakening cenotic stress in row plants sowing and less experimental sowing rates accelerated plants development phases
from sowing time to bushing and also during interphase stage from
tubing to flowering was observed. With this, the above mentioned
variants showed a longer plant development period from full
germination to tubing and from flowering to wax ripeness.
