The article is dedicated to the problem of full-value rations for farm animals and poultry at the expense of the use of different fat additives. We have also discussed the prospect of dry palm oil usage in geese feeding
The article presents the effect of boron fertilizer on growth, development and productivity of rice plants, the optimal dose and timing of application of boron fertilizers, providing maximum increase grain yield, calculated the economic loss of nitrogen, phosphorus and potassium and crop coefficients of their use of
fertilizer plants; we have also established the influence boron fertilizer on grain quality of rice
There was described the history of rice growing branch formation on Kuban from thirties to eighties of XX century: from first sowings to the production of a million ton of rice. The role of academician E.P.Alyoshin in the development of Kuban rice growing was marked. There were shown the ways of rice harvest increase on Kuban at present time
The results of development of rice breeding lines, carrying the wide range resistance gene to rice blast disease - Pi-40. For identification of the dominant allele of the gene the DNA - marker analysis was used. With co-dominant DNA markers plants from inbred populations that carry a dominant allele of this gene in the homozygous state were selected
In this work we examine the type of inheritance, number and force of the genes participating in determination of a quantitative attributes of length, width of grain, weight of 1000 grains at hybrids from crossing of the Iranian variety of rice Ambarbu with varieties of Virazh and Boyarin. It is established, that distinctions between samples of length of grain made 3 pairs of genes, of width of grain – 1 pair genes, of weight of 1000 grains – 2-3 pairs genes
In the main collectors in the North-West Caspian we have found the concentration of priority chemical elements: in water - Zn, Cu, Mn, Co, B, Mo, Cr, Ni, Pb; in sediments - Zn, Cu, Mn, Cr, Ni, Pb. It was found that a common and characteristic feature of drainage water is a low concentration of these elements investigated (except Mn, B, Pb). In the bottom sediments collectors content of gross forms of Zn, Cu, Mn, Ni, Pb and mobile forms of Zn, Cu was below the MRL and the content of the gross forms of Cr and Mn mobile forms was a little higher
The article investigates the impact of waste of elevators on morphological parameters and productivity of winter wheat grown on black leached soil
This article describes quantitative evaluation of add-ing succinic acid in the bran substrate when cultivating Pseudomonas fluorescens
This article reviewed the results of analysis of a balance of nitrogen, phosphorus and potassium in chernozem (typical black leached soil of Belgorod region) after two crop rotations by different cultivation technologies of agricultural crops. The balance of nutritional elements has been calculated and the optimal agro technology for deficitless balance of plant nutritional elements determined
In the article, the information of the influence of humival feed additive on hematologic parameters, development of a multichamber stomach, live weight, meat productivity, economical efficiency are resulted for growing of young sheep up to seven-month age
