Ryazan region annually receives stable yields of sugar beet roots 40 t/ha. Further growth of yields depends on balanced nutrition of plants cultivated hybrids, from the quality of the soil and of the phytosanitary State of sowing culture. Weed vegetation in wider spaced row crops of sugar beet in the initial periods of vegetation is high competition culture. The article presents the results of three studies on the effectiveness of the herbicide betanalnoj group, used to reduce contamination of sowing culture annual dicotyledonous weeds and increase the harvest of sugar beet roots. Studies conducted on experimental fields ISSA-branch FGBNU FNAC WIM (former AGRICULTURAL RESEARCH INSTITUTE in Ryazan). Soil: dark grey forest tjazhelosuglinistaja, humus content 4.0%, potassium and phosphorus-high pH is 5.8. Area of cultivated plots 50 m2, repetition, four sugar beet variety-Ocean. The predecessor-winter wheat. Under the autumn ploughing had made NPK120 under presowing cultivation-N60, SEV conducted seeder sowing machine. For crop protection herbicides were tested annually of sugar beet Betanal progress, UF-1.0 l/HA, Forte di Belvedere-1.0 l/HA, Betanal Max Pro-1.5 l/HA, Bajrang engineering works Super-1.5 l/HA, once applied to weeds. The harvest of sugar beet roots, take into account the square 10 m2 in 4-times repeated with each experimental plot by weighing machinery, processed data by ANOVA. The research found that studied herbicides efficiently at 87-92%, reduced infestation annual dicotyledonous weeds and increase the harvest of sugar beet roots to 29.9-44.1%

The article presents the results of a 3-year test of the herbicides Lontrel Grand, VDG, Piraklid, VDG and Lontrel-300, BP, used to reduce the clogging of sugar beet crops by perennial dicotyledonous root weeds and increase crop yields. In Ryazan region the conditions these malignant plants are found in almost all fields sown with sugar beets, which is particularly vulnerable because being a root crop it cannot seriously compete with weeds. With a strong contamination of the crop by perennial dicotyledonous root shoot weeds its yield may decrease by more than 50%. Tests of drugs were carried out on sugar beet cultivar Ocean sowings on the experimental field of the institute in four replications. The size of the experimental plots is 50 m2. The soil of the experimental plot is dark gray forest heavy loam, the content of humus is 3.8%, pH is 5.8 ... 6.0, the forecrop is winter wheat. The tested herbicides were introduced with the “Agrotop” backpack compression sprayer equipped with a two-meter boom, consumption rate of the working solution was 200 l / ha. Twice sprayed in the phase of cotyledon leaves and 2 - 3 pairs of real leaves of the crop, once – in the phase of 2 - 3 pairs of leaves. The development phase of perennial dicotyledonous offset weeds during the first spraying is the leaf rosette, during the second spraying the length of the sow-thistles and thistles is 10 ... 20 cm. With the level of weediness of the crops by the Cirsium arvense, Sonchus arvensis to 26 pcs / m2 the studied preparations reduced the weediness of the crops of these weeds by 85.0 - 92.0% and increased beet root crops by 2.8 - 4.4 t / ha.

Relevance. One of the key tasks in the cultivation of seed potatoes is to obtain the optimal level of yield, the quantitative output of the standard fraction of seed tubers and ensure the quality of seed potatoes at the level of regulatory requirements of the standards set for the respective seed categories. In order to obtain a quality seed, it is necessary to form such a crop that its structure had the largest amount of seed standard fraction of tubers, and plants were less affected by viral infection. Methods. Studies on the effect of different doses of mineral fertilizers and the timing of the mowing of top on the output of seed potatoes of the variety Evpatiy were conducted in 2018–2020 on the experimental fields of ISA. The technology of cultivation of the new variety was studied in the crop rotation: peas — winter wheat + runchweed — potatoes — spring wheat. The area of experiment is 0,25 hectares, the accounting area is 10 m2, the repetition is fourfold. Soil of the site: dark gray forest heavily sougly; humus content 4.7%, potassium — 18,4 mg/100 g of soil, phosphorus — 22,3 mg/100 g of soil; soil pH 5,0. Experiment scheme: introduction of mineral fertilizers before planting and mowing top after flowering: N96P96К96 — 30 days, N96P96К96 — 45 days and N128P128К128 — 30 days, N128P128К128 — 45 days.Results. On the version with the introduction of mineral fertilizers N96P96К96 before planting and mowing tops 30 days after flowering, a tuber yield of 30.8 t/ha was obtained, with a yield of seed tubers of 37.3%. On the version with the introduction of mineral fertilizers N96P96К96 and mowing of tops 45 days after flowering, a tuber yield of 34.8 t/ha was obtained, with a yield of seed tubers of 42.2%. The use of mineral fertilizers with a rate of consumption N128P128К128 before planting and mowing tops 30 days after flowering contributed to the yield of tubers of 34.3 t/ha, with a yield of seed tubers of 45.6%. On the version with the introduction of mineral fertilizers N128P128К128 before planting and mowing tops 45 after flowering a tuber yield of 36.7 t/ha was obtained with a yield of seed tubers of 42.2%.

The paper considers the question of bringing the existing set of laws, regulatory and legislative documents in line with the Digital Earth - new and promising universal and global environment for the information integration on all possible scales simultaneously. Existing of 4 possible geovisualization methods is stated, typology of geovisualization methods is proposed and discussed. A practical approach for determining the belonging of visualization to a particular type, based on the use of diagrams "angle-range", is proposed. Concept of 3D-documents within Digital Earth paradigm is unveiled and explained, brief history of the developing and adopting of this concept is described, the prospects of the future evolution of 3D-documents are considered briefly.

In the Ryazan region using of modern and promising herbicides is effective in order to reduce the number and harmfulness of weeds. Initially, it is necessary to study the phytosanitary state of crops for each specific site and choose the most effective herbicide depending on the weeds species composition and thresholds of economic harm. The purpose of the study is to determine the biological and economic efficiency of drugs (Fenizan, BP and Morion, SK) and to assess their impact on the phytosanitary state of crops. The research was carried out on the experimental fields of the Institute of Seed Production and Agricultural Technology – it is a branch of the Federal Scientific Agroengineering Center VIM. The soil is dark gray forest heavy loamy, humus content – 4.0%, potassium and phosphorus – high, pH – 5.8. The cultivated plot area is 50 m2, four times the replication, the winter wheat variety – Viola. The predecessor is autumn fallow. The Azophoska (nitrogen-phosphorus-potassium fertilizer) application is 1.0 c / ha for pre-sowing cultivation. In the phase of spring tillering was performed fertilizing with ammonium nitrate (1.0 c / ha). The results of two-year field tests of post-emergence herbicides used in the autumn tillering phase to reduce weediness of winter wheat crop and increase yields are presented. It was found that in the region conditions of the tested preparations effectively reduced the contamination of crops and increased the grain yield of winter wheat by 2.5-5.5 c / ha.
