ACTUAL THEME

Introduction and adaptation of precision agriculture technology at field experiment

The article provides information on the implementation and development of technology in precision farming field experiment Precision Agriculture Centre of RT SAU. Among the defining elements of precision agriculture technologies implemented in the field experiment are: agricultural crop cultures using navigational equipment: autopilot, fertilizer and herbicides depending on the crop, the availability and abundance of weeds in some areas of the field with special scanners and sensors and also assessment of crop yields, taking into account the binding spot on the field and preparation of electronic maps.

Keywords: precision agriculture, GPS, autopilot, fish aisle, diversity of soil fertility, differentiated fertilizer and pesticides, crop mapping, electronic maps yields.


MICROELEMENTS AND MICROFERTILIZERS

Influence of chelate microfertilizers on yield and quality of plant production

It’s shown that application of chelate microfertilizers rather improves plant production quality: albumin content in cereal crops grain increases, starch content – in potato, nitrates’ content in carrot and beet decreases. Optimization of plant nutrition can as improve harvest quality rather decrease risk of pollutants accumulation.

Keywords: microfertilizers, presowing treatment, harvest, production quality.


Research of protective influence of Se, Si and Zn on grain crops sustainability to draught

The article shows the results of vegetation experiment for researching of selenium, silicon and zinc resistant mechanism under drought soil conditions. There are dynamics of photosynthetic pigments and intake of nitrate nitrogen into plants.

Keywords: soil drought, seeds presowing treatment, selenium, silicon, zinc, wheat, triticale.


Monitoring of microelemental condition of agroecosystems

Methodological aspects of the complex research of microelements in basic components of agroecosystems at modern stage are presented in article. Monitoring of microelemental condition of agrolandscapes has been substantiated. Necessary of formation of the federal and regional data bases of microelements distribution in soil, parent rock, ground waters and plants is considered. Urgency of formation and introduction of biotechnologies for harvesting of plant production with stable microelemental parameters is shown.

Keywords: microelements, agrolandscapes, monitoring, biotechnology.


PLANT PROTECTION

Influence of chemization and growth regulator on impurity of sown maize

The article deals with the results of application of pregermination and postgermination herbicides on different agro-phones. Their role in decreasing impurity of maize is shown. The use of growth regulator Zircon under herbicides application has been studied. Established that complex application of preparations didn’t increase weeds tolerance.

Keywords: maize, herbicide, growth, regulator, fertilizers, weeds.


Research of various hybrids of sugar beet sustainability to the Cercospora

Using technologies of sugar beet harvesting without beet tops removal from field lead to accumulation of infection, decease reaches stronger phase and decrease yield and saccharinity. So at special conditions it’s necessary to grow only tested and sustainable hybrids. Determination of more sustainable sugar beet hybrids to the Cercospora with high productivity estimated by saccharinity and volume of 1 hectare harvest of two-year researches is presented in article.

Keywords: sugar beet, hybrids, Cercospora, yield, sugar content.


Experience of bioregulators to prevent the negative effects of the herbicide on flax crops

The use of bioregulators on the basis of protective-stimulating complexes in the cultivation of flax can reduce herbicide use harsh impact on plants, increasing crop yield and phytosanitary condition of crops.

Keywords: phytosanitary condition of sowings, bioregulators, flax, herbicides, treatment efficiency.


Role of a variety and plant security facilities in technologies of winter wheat cultivation

It was proved on the basis of references analysis and the authors' own studies that grades play a sufficient role in decrease of pests and diseases development. The share of varieties influence on productivity is estimated as up to 15-20% and more in cultivation technologies. Grain consumer quality is improving. The gluten contents in grain reached 39% and varied from 25% with Nemchinovskaya 24 to 39% with Moskovskaya 40. All the varieties are referred to group II according to the quality of gluten contents.

Keywords: variety, technology, pests, diseases, weeds, plant protection means.


YOUNG SCIENTISTS RESEARCH

Increase of Sugar sorghum green mass yield at sod-podzolic soil of North-Eastern part of Belarus republic

We have presented the results of research into the influence of terms of sowing, doses of applied nitrogen fertilizers and microelements and Epin on the yield and quality of green mass of Sorghum sacchartum Slavianskoe priysadebnoe. Optimal term of sowing in conditions of sward-podzolic light loamy soils in the north-east of Belarus was the first ten days of June and application of fertilizers in the dose of N80P60К120 + Zn + Cu + Epin (yield of green mass was 62.17 t/ha, of dry matter 15.43 t/ha, the content of raw protein – 10.94%, raw fat – 1.28%, raw cellulose – 26.13%, raw ash – 3.66%, nitrogen-free extractive substances – 60.65%, sugar – 17.98%, exchangeable energy – 10.182 MJ/kg, profitability – 44.28%).

Keywords: Sorghum sacchartum, yield, fertilizer, microelements, plant growth regulators.


Spring grain crops productivity under influence of abiotic stress factors after seeds treatment by Selenium, Silicon and Zinc

The article presents the results of field experience with the study of the protective effect of selenium, silicon and zinc to model stress factors (foliar treatment with herbicide Diquat and a solution of cadmium chloride) as an example of crops of wheat and triticale.

Keywords: oxidative stress, selenium, silicon, zinc, wheat, triticale, productivity, field experience, protein, gluten.
