The aim of the study is to find out the feasibility of including green manured fallow in specialized sugar beet crop rotations by comparing necessary assessment indicators with their values in a traditional crop rotation with black fallow against the background of unequal fertilization levels. The study was based on the analysis of experimental data from a long-term stationary experiment, laid out simultaneously in all fields and variants on typical chernozem in triplicate. The results are as follows: within the same fertilization levels, no significant differences in the yield of winter wheat (sugar beet precursor) were revealed, and the yield of sugar beet in a crop rotation with green manured fallow was stably higher (no more than 5 to 7%), an increase in yield relative to the control fertilizer variant (6 tons of manure per hectare per year) against the background of a double rate of manure in combination with mineral fertilizers amounted to 21.7 to 23.4% for wheat and 14.3 to 15.6% for beets with an increase in the productivity of crop rotations (in natural and value terms) by 1.2 times, but an increase in costs by 1.3 times caused an absolute decrease in the level of profitability by 23 to 25%. Differences in the assessment indicators for specific fertilization variants increased over time due to an unequal degree of soil fertility reproduction, and therefore in the fifth cycle of the crop rotation with black fallow turned out to be 1.1 to 1.3 times greater than in the green manured rotation.

Under conditions of the Central Chernozem Region in the period from 1990 till 2012 long-term and short-term experiments were carried out in order to study the effect of different systems and methods of main soil treatment on weed infestation of plantings and yield of field crops. Soil and plant samples analyses were performed by customary methods. It has been defined that improved fall-ploughing and supplementary fall-ploughing at a depth of 6-8 cm allow reducing the quantity of weed vegetation in sugar beet plantings by 22 % and 33.3 % respectively compared to conventional (two-phase) fall-ploughing.

Energy Flows

The purpose of the study is to determine the suitability for making sound decisions on the reproduction of soil fertility of the following quantitative laws of the methodology for managing material and energy flows in crop rotations: the energy content of 1 ton of humus (in GJ) is equal to half the nitrogen contained in it (in kg); the amount of exchangeable energy (in GJ) in 100 kg of phytomass is equal to the halfsum (in kg) of nitrogen and phosphorus pentoxide (about 2/3 of it falls on nitrogen). The approbation was carried out on the data of long-term stationary experiment. The results are as follows: with an increase in the level of fertilizer, nitrogen removal with the yield increased by 30–40%, and that of phosphorus by 6–12%; due to doubling the manure rate and the use of mineral fertilizers, the phosphorus balance became positive, and the nitrogen one remained negative, but improved by 17–28% depending on the type of a crop rotation. The deviation of the calculated balance of the exchangeable energy from the actual one on the poorly and most richly fertilized backgrounds was -5.5 to -11.9% and 3.0 to 8.6%., respectively.

Productivity Indicators

A long-term field experiment was carried out at the Experimental Station of the VDU Agriculture Academy (formerly Aleksandras Stulginskis University), Institute of Agroecosystems crop rotation collection (equipped in 1967), during 2015–2017. The soil of the Experimental site is moderately fine textured Calc(ar)i-Endohypogleyic Luvisol. The research was carried out on winter rye (Secale cereale L.) ‘Matador’, winter wheat (Triticum aestivum L.) ‘Skagen’ and 71 spring barley (Hordeum vulgare L.) ‘Orphelija’, which were sown in 8 different crop rotations after different preceding crops and rye monoculture. The aim of the experiment was to investigate the effect of long-term crop rotation combinations on testing crops yield and productivity indicators. In many cases, rye productivity indicators were lower during 50-year monocropping. The best productivity indicators were obtained by growing rye in them in grass and fallow crop sequences, and for winter wheat in fallow with vetch–oat mixture for fodder and after manure application. In rye these indicators were more dependent on the precipitation amount and the amount of the sum of temperature during the period of generative organ formation. Among these indicators and the number of productive stems, a statistically strong and medium strength correlation interaction was identified: r = 0.83, P ≤ 0.01; r = 0.90, P ≤ 0.05; r = 0.58, P ≤ 0.05; r = 0.85, P ≤ 0.01; and winter weat r = 0.87, P ≤ 0.01; r = 0.89, P ≤ 0.01. The highest winter wheat productivity was established in crop rotation after perennial grasses and leguminous crops. Crop yield in monoculture decreases, but the optimal amount of mineral fertilizers saves lower but stable yields. Spring barley is less dependent on preceding crop, so it can be grown after winter cereals. However, they are more productive when sown after row crops and in crop rotations where one of the rotation members is fertilized with organic fertilizers.

Purpose. To determine the long-term effect of a complex of factors (anthropogenic and natural) on the productivity of sugar beet for a significant period and the level of pest reproduction. Study of short crop rotations. Methods. Field, laboratory, statistical. Results. The uneven distribution of precipitation during the sugar beet growing season has differently affected the efficiency of fertilizer systems and, as a consequence, the growth, development of plants and the yield of root crops. Yield of sugar beets at constant sowing on average for five years was dynamic, but its highest productivity, regardless of the fertilizer system, was in the first years of research, from 29.7 to 39.1 t/ha (on average for 1978–1982). Further cultivation in monoculture has led to yield reduction. The highest yield of sugar per hectare was also observed in the first five years, and varied in different fertilizer treatments from 4.67 to 6.22 t/ha. The lowest yield was in 1988–1992 and 1998–2002, 2.71 to 4.42 t/ha and 2.23 to 4.53 t/ha, respectively. Sugar beet yield in crop rotation was influenced by both forecrop and aftercrop. On average, during the years of research (2011–2019), the highest yield (43.0 t/ha) was obtained in the three-field crop rotation winter wheat — spring barley — sugar beet, while the lowest (41.8 t/ha) in the crop rotation sunflower — winter wheat — sugar beet, slightly higher in the four-field crop rotation soybean — winter wheat — sugar beet — corn (42.3 t/ha). The yield of sugar during continuous sowing, on average during the study period, was 3.5–5.1 t/ha, while in crop rotation it was 7.7–8.3 t/ha. According to the results of the survey of crops in the cotyledon phase, it was found that in unchanged sowing the density of common beet weevil (Bothynoderes punctiventris Germ) is quite high, 8.8 beetles/m2 (average for 2006–2008) and exceeds the harmfulness threshold (0.2–0.3 beetless/m2) several times. At this density, the damage to plant seedlings was significant. Conclusions. The yield of sugar beet is influenced by both natural and anthropogenic factors. Of the anthropogenic, in addition to fertilizers, it is important to adhere to scientifically sound crop rotation. Long-term stationary studies have shown that the cultivation of sugar beet in monoculture leads to a gradual and stable decrease in yield and, consequently, the yield of sugar per hectare. The use of mineral and organic fertilizers helps to increase yields, but not significantly. In addition to weather conditions, the yield of sugar beet in crop rotation is influenced by forecrop and aftercrop. In the studied crop rotations, the lowest yield was obtained in the crop rotation where the forecrop of beets was sunflower, and the largest yield was obtained with legumes. Observance of crop rotation affects the phytosanitary condition of sowing; therefore, in monoculture, the density of common beet weevil is much higher than threshold, which leads to additional costs.

Positive Effect

The results of long-term research in experiments with crop rotations with different clover saturation are presented. It is shown that the cluster has a positive effect on the main indicators of vegetation of dark-gray forest soil. The introduction of two fields of perennial grasses into the six-field crop rotation significantly increases both the humus reserves and increases the productivity of arable land by 1.5–2 times compared to the crop rotation with a field of pure steam.

The Impact

Due to the great economic significance of the sugar beet, the new production trends are aimed at improving the quantitative and qualitative properties and one of the basic agro technical measures that is directly dependent on the yield and quality of the turnip is the properly conducted plant nutrition. Exporting high quantities of nutrients from the soil, the sugar beet requires application of advanced agro-technology, primarily application of adequate and controlled nutrition and irrigation. Application of this measure, in combination with soil processing, has sustained influence over the following cultures in the crop rotation in terms of nutrients regiment and fight against weeds.In order to determine the effects of mineral fertilizers on sugar beet, field experiment was conducted on fluvisol soil. The experiment is set according to a random block system, following the standard methods of agricultural chemistry for conducting field trials. The experiment includes eight variants, as follows: 1. Control (non-fertilized), 2. NP, 3. NK, 4. PK, 5. NPK, 6. N2PK, 7. N2P2K, 8. N3PK.In the phase of technological maturity of sugar beet, collection of the vegetative material and measurement of the height of the biological yield of the turnips was carried out. Based on the survey results, it can be concluded that the variant N2P2K has achieved the highest yield of swollen roots, i.e. 69.330 kg/ha. The highest yield of leafy greens was achieved in the variant N3PK, i.e. 41.920 kg/ha, which indicates the fact that nitrogen has direct influence over the vegetation mass of sugar beet.

Buckwheat research has been carried out within the long-term crop rotation stationary that was established in 1969 as a part of the Research institute of Agriculture. Buckwheat proportion within the partcular crop rotations went up to 22%. The highest buckwheat yields were obtained from the buckwheat variants that where cultivated after winter rye, and within the buckwheat monoculture experimental plots. A considerable yield decrease was observed when cultivating buckwheat after potatoes. Weeds in the buckwheat sowing were effectively brought under control by the herbicide Butisane 400 (1.5 l ha-1), applied immediately after sowing and Betanal AM 2.5 l ha-1 after seedling in 2-3 leaves stage.
