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.

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.

The influence of rotation length and fullness of grain – fallow crop rotations with a different set of biological groups (biogroupps) - winter, early spring and late spring crops on the yield of grain crops and grain yield from 1 hectare (ha) of arable land in the chernozem steppe of the Saratov Right Bank is analyzed, based on calculations for 4-field - 8 rotations, starting from 1989 and ending in 2020 (2-field - 16 rotations, 3-field - 10). It was revealed that the highest grain yield of 1.63 tons (t) from 1 ha of arable land, both on average for 32 years (1989-2020), and (1.82 t / ha) in the first-fourth (1989-2004) and (1.44 t/ha) of the fifth-eighth rotations (2005-2020), is observed in the 4-field grain – fallow crop rotation with a set of biogroupps-winter, spring early and late. The absence of a field of spring late crop (millet) in the 2 - and 3-field crop rotations reduces the grain yield by 0.11 and 0.30 t/ha, respectively, in comparison with the 4-field, both on average for all years, and by 0.22 and 0.28 t/ha in the first-fourth and by 0.20 and 0.32 t/ha in the fifth-eighth rotations. During the transition from the first-fourth rotation to the fifth-eighth, a significant decrease in the yield of field crops was established: winter wheat in the 3-field crop rotation by 0.87 t/ha or 26.6 %, 2-field by 0.72 t/ha or 22.4% and 4-field by 0.70 t/ha or 21.8 %; millet by 0.43 t/ha or 16.3 %, spring hard by 0.40 t/ha or 29.6 %, soft by 0.35 t/ha or 24.6 %. In all three spring crops, the yield reduction is 2.0 times lower than that of winter wheat. In general, according to crop rotations, the yield of winter wheat, both for the entire period of research, and in the first-fourth, fifth-eighth rotation, fluctuated within limited of the error of the experiment.

Different Doses

The effect of application of different doses and combinations of mineral fertilizers in field crop rotation on the content of basic nutrients in plants, economic and relative removal of winter wheat, corn, spring barley and soybeans was studied. Soil - Luvic Chernic Phaeozem. The scheme of the experiment includes 11 variants of combinations and separate application of mineral fertilizers and, including the variant without fertilizer. It was found that the level of nitrogen content of easily hydrolyzed compounds in the soil significantly affects its content in the grain of spring barley, corn, soybeans (R2 = 0,92–0,93), less - winter wheat (R2 = 0,63). The content of mobile phosphates in the soil has almost the same effect on its content in the main and non-commodity part of the crop, regardless of the crop (R2 = 0,39–0,70). The smallest relationship between the content of mobile compounds in the soil and in the crop was in potassium, but in soybean seeds and straw of spring barley and soybeans it was clearly traced (R2 = 0,53–0,68). Nitrogen (64,4–149,9 kg / ha) has the largest share in the economic extraction of nutrients with grain and seed yield, followed by phosphorus – 21,1–51,4 kg P2O5/ ha, depending on the crop. On the formation of the crop unit of marketable and the corresponding amount of non-marketable crop products absorb nutrients in the following ratio N : P2O5 : K2O: winter wheat – 1 : 0,4: 0,7; corn – 1 : 0,3 : 0,8; spring barley – 1 : 0,4 : 0,7 and soy – 1 : 0,4 : 0,4. With the non-commodity part of the crop, nitrogen with corn stalks returns to the soil from economic removal – 28–36 %, phosphorus with soybean straw (47–54 %) and potassium with winter wheat straw and corn stalks – 74–80 %, depending on the experiment variant.

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.

SummaryThe purpose of this study is to evaluate the effect of organic farming technologies on the yield of alternative types of wheat: hard wheat (Triticum durum), spelt (Triticum aestivum ssp. spelta) and a common variety of (soft) winter wheat (Triticum aestivum ssp. vulgare). The experiment was carried out during 2010-11 and 2011-12, at the Radmilovac experimental field of the Faculty of Agriculture in Belgrade, according to the randomized block design in four replications. In addition to the control treatment (without fertilizers), microbiological fertilizers were applied in topdressing (alone) and in combination with organic fertilizer before sowing. Crops were grown under a four-crop rotation on leached chernozem in the rainfed water regime. The average yields of the varieties examined were not significantly different depending on the growing year, whereas fertilization showed a highly significant effect on the grain yield. The combined application of microbiological and organic fertilizers resulted in the highest yields in both years (5,209 and 4,992 kg ha-1, respectively). The selected wheat varieties exhibited different responses to the treatments applied. The highest yield was observed in the common soft wheat variety examined (5,170 and 5,611 kg ha-1), whereas the lowest in durum wheat (3,138 and 2,429 kg ha-1). The analysis of experimental factor interactions showed that statistically significant effects on the yield could be attributed to the year-fertilization interaction. The wheat yields obtained are similar to those observed in the conventional production system due to favorable weather conditions and a proper selection of the type and sequence of crops that are part of the four-crop rotation (winter wheat, maize, spring barley + red clover, and red clover).

Research on the effectiveness biomodified mineral fertilizers were carried out on the basis of Ulyanovsk SRIA – SamSC RAS branch during the rotation grain fallow five fields crop rotation: pure steam – winter wheat – spring wheat – barley – oats in 2013-2018. The field experiment scheme included options (except control): with the introduction of biologics BisolbiFit (introduction with seeds that were treated before sowing), azofoski N15P15K15, in pure form, modified with biopreparation azofoski in the same dose N15P15K15, half a dose of modified azofoski (N7, 5 P7, 5 K7, 5). The effectiveness of fertilizers and biopreparations in crop cultivation was studied on three backgrounds: natural (control), ammonium nitrate at a dose of 40 kg ai/ha (NH4NO3), and modified ammonium nitrate at a dose of 20 kg DW/ha. It was established that modification of azofoski with Bisolbifit biopreparation can significantly increase the coefficients of use of elements from it by plants. The latter allows to reduce the dose of fertilizer, without reducing the productivity of cultivated crops, twice. Long-term cultivation of crops using only mineral fertilizers and biological products led to a relative decrease in the humus content in the soil and its acidification. For 6 years, the content of humus in the arable layer of leached chernozem decreased by 0.12 %, and the acidity of the soil solution increased by 0.5 pHKCI units. In the conditions of the Volga forest-steppe, when cultivated on chernozems, the highest-yielding winter wheat is (up to 4.00 t / ha or more, in our experiments 3.88-4.80 t / ha). The average yield of spring wheat was 2.68-3.31 t / ha, spring barley 2.67-3.21 t / ha, oats 2.15-2.71 t / ha. The highest productivity of crop rotation was observed against a background with modified ammonium nitrate at a dose of 20 kg ai/ha (½NH4NO3) when applying modified azofoski (N15P15K15). Grain harvest for 2013-2018 in this variant was 13.36 t / ha, exceeding the control variant on this background by 1.31 t / ha.

The Grain Yield and Weed Infestation Rate of Winter Wheat by the Different Share of Cereals in Crop Rotations The aim of the study was to compare the grain yield and weed infestation rate of winter wheat in crop rotations with 40, 60 and 80% share of cereals and in continuous cropping. The trial was situated in the area of continental climate. The trial had two parts. In the first part, there were crop rotations with 40, 60 and 80% share of the cereals. Two levels of fertilization were used: H1 mineral fertilization + organic manure Veget; H2 mineral fertilization only. In the second part, winter wheat and spring barley were grown in monoculture. Three variants of fertilization were used: 1 - mineral fertilization; 2 - mineral fertilization + straw of cereals were ploughed; 3 - mineral fertilization + straw of cereals + organic manure Veget were ploughed in the soil. In the years 2006-2009 the grain yield, thousand kernel weight and weed infestation rate of winter wheat in different crop rotations and by the continuous cropping were investigated. The statistically higher winter wheat grain yield (6.50 t ha-1) was recorded by 40% share of cereals in crop rotation than by 60% and 80% share of cereals (6.23 t ha-1). The grain yield of winter wheat by continuous cropping was lower by 2.24 t ha-1 (34.46%) than in crop rotation with 40% share of cereals. The weed infestation rate by 80% share of cereals in crop rotation was determined 2.4 times higher than by 40% share of cereals.

Abstract Researches on the study of predecessors and biologization techniques in field crop rotations were carried out in 2018-2020 in the dry steppe zone of the chestnut subzone of light chestnut soils of the Nizhneje Povolzhje region. It is necessary to grow biennial melilot for green manure as a fallow-growing crop in a grain-steam five-field crop rotation in order to increase the organic matter input into the soil. A significant increase in yield was achieved in chickpeas for winter wheat, its straw was plowed into the soil. The highest increase in the spring barley yield was provided during the chickpeas and sorghum cultivation, which straw entered the soil. When growing spring barley on safflower, its straw was plowed into the soil, the yield was also higher than the control variant. The highest grain yield was achieved in the control grain-fallow four-field crop rotation with complete fallow, where the cultivated crops straw was removed from the field and grain-fallow-grass green manure seven-field crop rotation with seed fallow, where straw and melilot were plowed into the soil. Grain-fallow seven-field and grain-fallow-grass-cultivated green manure seven-field crop rotations, where oats and phacelia straw and green manure mass entered the soil, were inferior to the control.
