Combining ability with respect to “grain productivity” has been studied among thirty eight self-pollinated lines of maize of mid-early and early maturing in the system of hybrid combinations. The lines with high general (GCA) and specific (SCA) combinative ability have been hybridized. New high heterotic hybrids have
been developed on the basis of lines with high GCA and SCA
In this article the results of the research of quality characteristics of Russian and foreign rice varietieswere observed. A possibility of using the data in characterizing germplasm from the collection was discussed
There was substantiated the purposefulness of introduction
in non-irrigated organic gardens of apple-trees of Kuban zone of in-row sodding of soil with naturally growing grasses providing the increase of plant resistance to abiotic stressors of summer period and as a consequence, stabilization of generative activity and the increase of fruit productivity
The article presents some results of the industrial breeding of fine-wool ewes with rams of semi finewooled sheep breeds
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 studied the influence of factors of the medium on rice plants and hybrids of the first generation in the vegetation experience on the conditions of the artificial climate camera (ACC) and on the vegetation plot (control). There was determined the individual reaction of varieties on the conditions in ACC. There were revealed the modified changes at rice plants by a range
of features. There was made a conclusion on necessity of preliminary study of varieties in ACC before their introduction into hybridization
The article presents data on the morphological and biological characteristics of Agrodeum varieties, the results of the competitive test were shown, as well as the adaptability of varieties to different conditions of cultivation and the main indicators of quality of new grain varieties
The work on the study of the biological assessment of environmentally safe herbal feed additives for quail has found in the supplement that contains the seeds of soybean varieties Valens, the bird had higher growth rates than in the supplement of soybean varieties Vila. Using as a protein-based supplement
autoclaved soybean Valens varieties increases the profitability of meat quails from 22.52 to 28.76%, and the economic effect when used - to 32.5 rubles per 1000 quails compared with the addition made from soybean of Vilan varieties
The work on the development of technology for production of feed additives from soybean seeds and fruits of pumpkin has shown that the use of sodium bisulfate and lactic acid bacteria provide a high content of carotene in pumpkin paste (948 mg / kg and 819 mg / kg, respectively), and grinding soy before drying protein and vitamin supplements raises safety of carotene without destroying the urease
The purpose of this research is to assess the ability of
reclamation plantations of walnut and black nut to accumulate heavy metals in phytomass – leaves, shoots, fruits. The studies were conducted in the Rostov region, as well as in the Krasnodar and the Stavropol regions
