The Impact

Abstract Reduced tillage is considered as one of the main tools to save biological diversity; however, it increases pressure of diseases, including wheat leaf blotches. The aim of present study was to clarify the impact of reduced soil tillage on the development of winter wheat leaf blotches in different schemes of crop rotation. The impact of different growing technologies on the severity of winter wheat disease was evaluated in a two-factorial experiment: A – soil tillage system, and B – different combinations of wheat pre-pre-crop and pre-crop (wheat, oilseed rape, barley and faba beans). Diseases were assessed every 10 days approximately and total impact of diseases was evaluated by calculating AUDPC (Area under Diseases Progress Curve). Tan spot, caused by Pyrenophora tritici-repentis was dominated disease over the long period, regardless of meteorological conditions. Development of Septoria leaf blotch was not influenced by neither crop rotation nor soil tillage. The level of tan spot was essentially higher after wheat, regardless of the pre-pre-crop. Reduced soil tillage promoted severity of tan spot. Ploughing mitigated effect of previous crops and differences in tan spot level were insignificant. Despite many positive effects of conservation tillage, increasing of fungicide treatment could be necessary, in conditions, when the tan spot is most devastating and widespread wheat disease.

Legumes are increasingly important crops in most European Union (EU) countries because of the growing demand for feed protein, and also because they have been shown to improve the characteristics of soil. The main part of the crop rotation is taken up by cereals, but they are connected with undesirable side effects, such as the unilateral utilization of ingredients and the heightened risk of plant diseases, e.g., Fusarium. Simplification of farming methods has become increasingly popular as growers search for cheaper production technologies. However, the effects of long-term simplification in tillage practices on the production and economics of narrow-leafed lupine (NL) cultivation have not been studied. In 2012–2016, we carried out a field experiment in Poland with a one-factorial design with four replications. The aim of the experiment was to evaluate the productivity effect of conventional tillage (CT), reduced tillage (RT) and no-tillage (NT) on NL-winter wheat (WW)-winter triticale (WT)-winter barley (WB), rotation. Our results show that the productivity of this crop rotation was lower under RT and NT systems than under CT. From a practical point of view, the reduction of cultivation in rotation with 75% of cereals caused a decrease in yield in all species, which can result in resign of using the RT and NT in conditions of Albic Luvisols soil, as classified according to the World Reference Base (WRB). The highest incomes were found when the CT system was used with NL. Although income losses exceeded the value of savings in both minimalized soil tillage systems (RT and NT), all tillage systems of NL were profitable.

Wheat Cultivation

In modern agriculture, resource-saving technologies for cultivating grain crops and their optimization are becoming more and more relevant. The use of scientifically-based crop rotations, tillage methods and doses of mineral fertilizers allow increasing economic efficiency of winter wheat cultivation. The purpose of the research was to assess the yield and quality of winter wheat grain depending on different doses of mineral fertilizers under non-moldboard soil tillage in the crop rotations of the Central Chernozem Region. The research was carried out in 2012-2020 in a stationary multifactorial field experiment in Federal Agricultural Kursk Research Center. The experimental design included the following options: Factor A – crop rotations (grain-fallow-row, grain-grass-row, grain-grass); Factor B – mineral fertilizers (without fertilizers, N20P40K40, N40P80K80 kg ha-1). The soil of the experimental site is represented by typical, medium-loamy chernozem. The paper shows that the yield of winter wheat grain in the context of non-moldboard soil tillage was higher in the grain-fallow-row crop rotation and amounted to 3.34 t ha-1. In the grain-grass-row and grain-grass crop rotations, yield decreased by 6.6 % and 10.2 %, respectively. The maximum grain yield (3.98 t/ha-1) was obtained in grain-fallow-row crop rotation with N40P80K80. An increase in fertilizers doses led to protein and gluten content increment from 12.6 to 13.3 % and from 22.8 to 25.6 %, respectively; however, the differences in crop rotations were within the limits of experimental error. The grain nature varied according to the studied factors from 708 to 735 g/l-1 and was higher in the grain-fallow-row crop rotation with a dose of mineral fertilizers N40P80K80. Despite more significant net income after increased fertilizers dose (N40P80K80), the increase in the winter wheat grain yield did not allow obtaining a higher level of profitability compared to N20P40K40. Winter wheat cultivation in grain-grass-row crop rotation with N20P40K40 was the most cost-effective. In this variant, the cost of grain was the lowest (4.92 thousand rubles t-1); the profitability, on the contrary, was the highest (103.4 %).

The advantages of the three- and four-crop rotations in relation to the two- crop rotation are reduced frequency of soil tillage, and thus savings in energy sources, lower intake of mineral nitrogen fertilisers and the amount of applied herbicides. The aim of the present study was to indicate the importance of a proper alternation of crops in the three-crop rotation system and to compare the advantages of cultivation of maize after winter wheat or soybean in terms of reducing weediness, formation of the harvest index and grain yield. Results of long-term studies have shown that the crop sequence significantly contributed to the decrease in fresh biomass of weed and the increase in the harvest index and grain yield in the maize-winter wheat-soybean rotation in relation to the maize-soybean-winter wheat rotation.

In the last years there has been a slight increase in average annual temperatures, as well as a high fluctuation in the distribution of rainfall, thus the reduction of the effects of atmospheric and pedological drought is part of the reasons that determine the orientation towards new variants of soil tillage. The experiment conceived and performed at ARDS Turda includes four variants of soil tillage: plow with the turn of the furrow (CS), chisel (MT), disk (MD) and no tillage (NT), in a 3-year crop rotation of soybean - winter wheat - maize. The momentary water reserve was higher in the MD and NT system compared to the CS, MT. The specific resistance of the soil to penetration (Rp) in NT, MD are higher compared to the CS and MT systems. Soybeans can be cultivated in a MT, the yield difference compared to the CS is 107 kg/ha. Compared to CS (66.5 L/ha) significant reductions of diesel consumption are made in the MD system (21 L/ha) and in the NT (31.7 L/ha).

The article analyzes the influence of the processes of decomposition of winter wheat straw under the influence of destructors, which are embedded in the soil with implements with different designs of working organs, in the grain-crop rotation of the research field of the South Ukrainian Branch of L. Pogorilyy UkrNDIPVT on productive indicators of production activity, such as the yield of sunflower seeds, the production cost of the resulting products and the profitability of production. The goal of the research is forming and determination of the optimal economically effective system of technical and technological support of farms, when using winter wheat straw for fertilization with its preliminary processing with destructors, which helps to reduce the technogenic load, increase the productivity of the crop production industry and preserve soil fertility in crop rotations on the irrigated lands of south of Ukraine. Research methods – field, quantitative-weight, visual, laboratory and mathematical-statistical. In the crop rotation investigated five systems of basic tillage different in methods, techniques and depth of soil loosening on a background of straw treatment with destructors. Results: it has been established that when growing sunflower in the arid conditions of the southern part of the steppe zone of Ukraine on non-irrigated lands, it is advisable to use winter crop residues for fertilizing, treat it with destructors in combination with ammonium nitrate and plant it in the soil using deep plowing, which creates favorable conditions for its decomposition and formation of seed productivity at the level of 2.58 t/ha. Conclusions: it has been established that the economic effect of the use of destructors with plowing on the 30-32 cm and moldless loosening on the 40-42 cm is several times higher than the additional costs of introducing a destructor and ammonium nitrate. Plowless and shallow tillage and sowing in pre-uncultivated soil proved to be ineffective in an arid Southern climate on non-irrigated lands with a low moisture coefficient, even when treatment with destructors, as a result of which additional costs were received from UAH 0.16 for each hryvnia up to UAH 1.63 loss.
