Modern soil tillage systems based on different tools than mouldboard plough have very often stronger weed occurrence, which can be a serious problem for achieving high yields. An obvious solution for weed suppression is a herbicide, whose improper use can deteriorate environment and lead toward serious ecological problems. In order to investigate the interaction between soil tillage and herbicide, trial was set up in Valpovo in seasons 2008/09 - 2010/11. Two soil tillage systems (CT-conventional tillage, based on mouldboard ploughing, and CH-chiselling and disk harrowing, without ploughing) and five herbicide treatments (NH-control, no herbicides; H10- recommended dose of Herbaflex (2 l ha-1); H05-half dose of Herbaflex; F10- recommended dose of Fox (1.5 l ha-1); and F05-half dose of Fox) were applied to winter wheat crops. Results showed similar effects of soil tillage on the winter wheat yield, whereas different herbicide dosages showed similar weed suppression and influence on winter wheat yield.

The article presents the results of three-year studies to determine the effectiveness of local chisel, ultra-deep chisel, chisel conventional and disk tillage when growing winter wheat after fallow in the conditions of the Left-Bank Forest-Steppe of Ukraine. It has been established that changing the plowing of local or disking soil tillage leads to an increase in the density and hardness of the arable layer. Solid chisel tillage ensures the agrophysical state of the soil at the level of plowing. Chisel loosening improves the structure of the arable layer due to an increase in the number of water resistance aggregates by 2.5–3.4 % in comparison with plowing. The methods of soil tillage in fallow have little effect on the change in the moisture content of the arable and meter layers, which is facilitated by the accumulation and retention of moisture during the maintenance of fallow. Chisel tillage contributes to an increase in soil protection efficiency of the surface by 5–7 % in comparison with plowing due to the partial preservation of crop residues in the period after harvesting the predecessor to the beginning of summer, improvement of the structure of the upper layer and differentiated redistribution of the root system. The highest level of soil protection efficiency is provided by local chisel loosening. All non-moldboard tillage in fallow contributed to an increase in the yield of wheat grain in comparison with plowing, especially after solid loosening with a chisel plow at 33-35 cm, where an increase in yield was recorded by 0.36 t/ha (9 %). An increase in the level of profitability by 16–25 % makes it possible to recommend chisel local and solid loosening by 33–35 cm in a fallow when growing winter wheat in the conditions of the Left-Bank Forest-Steppe of Ukraine. Keywords: winter wheat, chisel loosening, local loosening, efficiency, density, hardness, water resistance, yield.

Tillage Methods

Purpose: to study the influence of soil cultivation methods on soil moisture-temperature regime and the winter wheat yield under conditions of insufficient and unstable moisture. Materials and methods: the study of various primary soil tillage methods was carried out under the conditions of long-term stationary experience in 2017–2019 on the isolated field of Federal State Budgetary Scientific Institution “Asovsliy Scientific Centre “Donskoy” (southern zone of Rostov region). The cultivated crop is Stanichnaya variety winter wheat, the predecessor is peas. The experimental site soil is ordinary calcareous heavy loamy chernozem. The studied tillage methods are surface, shallow, moldboard and zero (direct seeding). The method for determining the relative humidity and soil temperature in an autonomous mode was based on the use of Watch Dog 1400 Micro meteorological stations (recorders) from Spectrum Technologies, Inc., the soil moisture and temperature sensors were located at a depth of 30 cm. At the same time, the air humidity and temperature and the accumulation precipitation were monitored. Results: it was found that in the southern zone of Rostov region, zero tillage throughout the entire observation period provides high moisture conservation, preventing soil overheating, at the same time allowing to obtain a consistently high yield of winter wheat, which compares favorably with other tillage methods. Conclusions: comparison of various tillage methods with leading in all indicators zero tillage allowed to establish that, on average, with surface tillage, soil moisture is lower by 17.75 %, soil temperature is higher by 4.12 %, and yield is lower by 8.37 %. With shallow tillage, the soil moisture is 20.12 % lower, the soil temperature is 12.19 % higher, and the yield is 12.14 % lower. With the moldboard method, soil moisture is lower by 13.19 %, the soil temperature is higher by 11.48 %, and the yield is lower by 5.44 %.
