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 results of the long-term investigation of the stabilization of the humus content in the soil by the agricultural methods are contemplated and summarized in the article
Based on obtained experimental investigations it is shown that microelements included into winter wheat fertilization system positively influence plants mineral nutrition, quantity and quality of the crop
There are comparative characteristics of agronomic biological qualities of young pigs of Canadian breeds: yorkshire, landrace and duroc
The results of carried out researches allow to recommend to production the new prospective hybrids of sunflower NK Ferti, Opera PR, Savinka which allow to increase oil fullness of oilseeds up to 51,0 %
This article presents the results of studies of the effect of different cultivation technologies of winter wheat on the content nutrition elements in the soil
The article provides an overview of the results of the research of non-root treatment of bushes with activated water with the features of BAS. We have found that activated water, charged with the "Akvator" device through the BAS matrix has the property of impact on plant and the efficiency exceeds impact of BAS solutions themselves
The article presents the data of the degree of allelopa-thy-optical activity of extracts from the aerial parts, roots and rhizosphere of weeds, which is manifested in the inhibition of germination of winter wheat. Rusty-negative balances of cockle and wild oats, containing cellulose and decomposing slower, depress the test-culture of winter wheat after mineralization within 30 days
Nitrogen supply of soils is an important factor in the successful cultivation of agricultural crops. Nowadays, in the Central Black Earth region there are planted orchards with high density of trees, with installed systems of drip irrigation and fertigation. Such orchards are relatively new, particularly in this region. Fertigation ambiguous effects on soil structure and its content of nutrients, especially hydrolysable nitrogen. Therefore, the study of the distribution of hydrolysable nitrogen in the soil under the influence of fertigation and drip irrigation is important. The aim of our research was to investigate the distribution hydrolysable nitrogen in the root soil layers 0-20, 21-40, 41-60, 61-80 cm. Investigations were carried out according to conventional methods. In these layers of the soil, we have determined the content of hydrolysable nitrogen and yield. As a result, we have found that in variants with fertigation were the highest yield. In addition, with fertigation it was noted higher content of hydrolysable nitrogen in the soil as compared with the control without irrigation, especially in the deep layers 21-40; 41-60 and 61-80 cm. It was also noted increase of hydrolysable nitrogen in the soil along the periphery of the wetting
Chemical and amino acid composition of bare-grained barley was studied. Use of bare-grained barley as a component of compound feeds for young pigs favors the increase of live weight, decrease of food conversion rate and increase of economic efficiency
