The article substantiates the necessity of desiccation for seed crops of sweet sorghum. The analysis of the productive characteristics of the sorghum presowing after treatment is made. The effect of desiccation to reduce contamination of seeds with major diseases of sorghum has been studied
The review of the studying digestibility and assimilation of broilers diet nutrients under the influence of multienzyme composition Ronozim VP, phospholipid preparation of lecithin and probiotic Bifidum for agricultural animals is given in this article. The most important results of the effective use of mixture of biologically active substances included in diets are also discussed
In recent years leaf tan spot had dominated into
pathogenic complex of wheat in southern Russia. The
causative agent of this disease is hemibiotrophic
ascomycete Pyrenophora tritici-repentis (Died.)
Drechsler; imperfect state of Drechslera triticirepentis
(Died) Shoem. It causes two different
symptoms in susceptible wheat varieties: chlorosis and
necrosis. Under epiphytotic disease progression crop
losses can achieve 65%. One of the most important
elements of phytosanitary control of wheat cenosis is
scientifically relevant chemical fungicides application.
Biological efficiency of some fungicides against
Pyrenophora tritici-repentis has been estimated.
Research was conducted on the experimental ground
of FSBSI ARRIBPP on the variety susceptible to the
pathogen – Krasnodarskaya 99. Preparations were
tested one time at leaf-tube formation (Z37) phase or
two times: at leaf-tube formation (Z37) and start of
heading (Z51) stages. Double treatment was more
effective than a single one. Fungicides “Amistar extra”
and “Prozaro” have got the high biological efficiency
– 80,7 and 83,7%, consequently, and longer protective
period (up to 40 days) in comparison to every tested
fungicides

In the article there was given the survey of research results of leaf and leaf surface area potential of different origin in the conditions of Taman
In this work, the influence of 10 stimulators on occur-rence of roots in plants of green shanks of 14 types of stocks of fruit crops is shown. Types of preparations are allocated, at which qualitative root-stocks mate-rial for each investigated genotype in a hothouse with the mechanism forming a fog are received
The article is dedicated to the problem of different fat additives use in the rations for agricultural animals and poultry
USE OF NONTRADITIONAL FERTILIZERS IN CULTIVATION OF PLANTED SCOTCH PINES ON THE RECULTIVATED GROUNDS
The results of use of nontraditional organic fertilizers on the basis of wastewater sludges and sawdust in sand pits earth stabilization are considered. It was ascertained that a dose of introduced fertilizers has higher influence on hydrophysical and agrochemical properties of soils than shelf life of the fertilizers. A tendency of enhancing growth of intended purpose planted pines on the back of improvement of physical and chemical and biological properties of sandy soils, enrichment of species composition with grassland vegetation after nontraditional organic fertilizers treatment is revealed
