INTERRELATIONS BETWEEN PRODUCTIVITY AND ELEMENTS OF ITS STRUCTURE AT GRADES OF SOFT WINTER WHEAT
Description
Correlation interrelations of some morpho¬logical signs of winter wheat and their influ¬ence on productivity are established. Positive correlation communication of efficiency with weight of grain with an ear (r=0,70) is revealed

EFFECT OF BASIC TILLAGE ON THE EFFICIENCY OF MAIZE CULTIVATION IN STAVROPOL TERRITORY
06.00.00 Agricultural sciences
Description
The paper reviews the results of the study of small moisture conservation basic tillage cultivation technology in corn hybrids of different maturity groups of foreign breeding in areas of unstable moistening of the Stavropol Territory. The biological characteristics of plant growth and development of corn, as well as the formation yields of maize hybrids of different maturity groups, the nature of variation in their productive capacity and economic efficiency of small primary tillage are discussed

Description
On the basis of the data gathered from various districts of Medial Siberia it is mounted, that at trees of the Siberian fir (Abies sibirica) for associations d1.3 =f (dп) and dп =f (d1.3) a build-up of the uniform normative (even at level of a wood band) leads to the significant magnitude of errors, but can be used at study of blanket regularities

Description
In the article it is offered to count the spatial sign with provision for mosaic-tiered structure of wood when estimating rising trees. It is noted that the diameter of stems has mediated (indirect) relationship with average distance to the nearest tree

THE GENERALIZED DEPENDENCE OF HEIGHTS ON DIAMETERS IN PINE FOREST STANDS
06.00.00 Agricultural sciences
Description
The aim of work is to get prognostic equation, providing analytical description of height dependence on diameters by thickness of steps for forest stands of Krasnoyarsk forest-steppe.

06.00.00 Agricultural sciences
Description
Models of model trees in the manner of equations for calculation of the current increase of trees at radius in cedar, mixed fir and pine plantings are received. At calculation of the current increase at radius and height using the diameter of a tree on height bosom without cortex, age tree and average distance from nearest tree on radius is recommended.
