Formation of the leaf surface area of spring wheat in various cultivation technologies

The article analyzes the research on formation of leaf surface area spring wheat Darya variety in different cultivation technologies chernozem soil Kursk Region. aim was to study peculiarities depending technology and identify conjugate relationships indicators under conditions soils results conducted studies indicate that intensive contributes activation assimilation apparatus leaves during entire growing season crop. A high direct correlation between Z 13 55 phases application mineral fertilizers established (r = 0.73; 0.80, respectively). At 25 has a noticeable relationship with primary tillage 0.51) moderate one 0.36). use sugar beet tops as organic fertilizer had positive effect plant at 55, evidenced by 0.52; 0.52, It found flag leaf, well its length width, increased decrease density standing plants per square meter cropped area. width decreased height plants, while increased. development directly affected accumulation dry weight 0.53), total 0.72), ear 0.75), which turn is closely correlated grain from 0.70). Thus, evidence influence crop yield presented.
