A stationary experiment at Agrochemistry chair of Kuban' state agrarian university has revealed certain changes in humus contents and physical and chemical properties of black leached soil after two stages of field crop rotation as a result of long-term application of mineral fertilizers
In this article tendencies of vegetable production manufacturing in all categories of facilities of Krasnodar region are analyzed. Problems of increasing of an overall performance of agrarian and industrial complex are proved.
Results of reconstruction of a spare of mixed plantings after utter chopping by means of standards, formed by miscellaneous authors are presented in the article. The possibility of using used and newly designed tables is noted
Results of the long studies of the horizontal structure of different plantings in Mid-Siberia are presented in article. The horizontal structure of the plantings is characterized with significant variety of trees placing. Maximum full (normal) plantings of pines with uniform structure are characterized by casual trees placing. The modal plantings of pines with determined probability were characterized by group placing of trees.
Cedar and fir plantings with different structure have a group distribution of trees and young plants that is normal for the nature of these woods.
Solving of problems of the influence of irrigation on ecological situation and creation of optimum land-reclamation conditions are impassible without using of the mathematical modeling methods.
The work provides the idea of solving of the land-reclamations problems with the using of systematic-cognitive analysis.
SUBSYSTEM OF THE AUTOMATED DRAWING UP OF BALANCE SOIL AND CALCULATION OF REQUIREMENT FOR FERTILIZERS
Plant growing successes influence the effectiveness not only the branch in itself, but the other agricultural branches and economics of agricultural enterprises in general. In the article the method of calculation of sufficient balance soil is considered.
In the course of research the impact of polymeric pellicle-forming growth regulators (PGR) on the growth and development of rice plants while cultivated in conditions of salinity has been studied. It was ascertained that preseeding PGR treatment of seeds at the rate of 10 liters of solution for 1 (one) ton of seeds boosts germination energy, germinating ability of seeds, sprouts, length gets extended and weight enlarged. PGR lead to increase of electrochemical gradient on the membranes of chloroplasts, tilacoids and acceleration of electrons transport between I and II photo systems. PGR diminish toxicity of salinity which is fixed in parameters measured in experiments that are close to the control values. PGR application improves parameters of the structure of rice crop cultivated in conditions of salinity.
Trapsa is a Greek native variety. It belongs to the variety group of the Black sea basin (convar. pontica subconar. balcanica Negr.) ,has limited spreading.
The length of productive period is 156-165 days. Variety is medium-sized. Degree of cane maturation is high. Productivity is very high. Percentage of fruitful tillers is 90. The average mass of clusters is 500 g. It differs with high drought resistance and average resistance to fungi diseases. Under bud germination is recognized by crown of green color with winy-red shadow, with strong webby swelling. Plate of a leaf is large, dark-green shadow, form is pentagular, with five lobules, top surface of plate is honeycombed. Cluster is large, conic and compact. Flesh with nice variety after taste. Berry is average size, round, navy-black color. Sugar content is high. Variety is for making of high quality red wines of different categories in southern zones of grape-growing with hot and dry climate.
Results of morphobiological analysis of productivity and adaptivity of corn collections samples of ARRI named by N.I. Vavilov to the concrete ecological
Conditions. More than 60 samples ( varieties, hybrids, self-pollinating lines) concerning to the different
Subspecies are casted.
Characteristic of financial-economic activity of agricultural enterprises and qualitative land condition is casted in the article. Arrangements connected with biologization of agricultural production are considered and assessment of its efficiency is given.
