An experiment with five different tillage systems and their influence on physical properties of a silty loam soil (Albic Luvisol) was carried in northwest Slavonia in the period of 1997–2000. The compared tillage systems were: 1. conventional tillage (CT), 2. reduced tillage (RT), 3. conservation tillage I (CP), 4. conservation tillage II (CM), 5. no-tillage system (NT). The crop rotation was soybean (Glycine max L.) – winter wheat (Triticum aestivum L.) – soybean – winter wheat. Differences between tillage systems in bulk density, total porosity, and water holding capacity and air capacity were not significant in winter wheat seasons. In soybean seasons, significant differences between some tillage systems were recorded in bulk density, total porosity, air capacity and soil moisture. The deterioration trend of physical properties was generally increasing in the order CM, CT, CP, NT and RT. The highest yield of soybean in the first experimental year was achieved under CT system and the lowest under CP system. In all other experimental years, the highest yield of winter wheat and soybean was achieved under CM system, while the lowest under RT system.

Crop Sequence

A 3-yr field experiment was conducted on a Burford loam soil to examine how tillage practices and crop sequences affected the winter wheat (Triticum aestivum L.) crop in Ontario. Three-year crop sequences of wheat-wheat-wheat, soybeans (Glycine max Merrill)-wheat-wheat, corn (Zea mays L.)-barley (Hordeum vulgare L.)-wheat, corn-soybean-wheat, and alfalfa (Medicago sativa L.)-alfalfa-wheat were planted with zero-till, minimum tillage, or conventional tillage systems. When wheat followed wheat, plant populations and head numbers were lower and head emergence delayed relative to wheat following another crop. Grain yields were 20% higher on average when crops other than wheat preceded wheat. Reduced tillage treatments resulted in delayed head emergence, but final grain yield components and yield did not differ significantly among tillage treatments. Results from this study support the relatively common production practice of rotating winter wheat with other crops. In addition, the use of conservation tillage systems appeared to be feasible for winter wheat production under the soil and climatic conditions prevailing in this study.

From 1996 to 1998 five different tillage systems were compared in maize (Zea mays L.) and winter wheat (Triticum aestivum L.) production on one experimental field (silty loam - Albic Luvisol) located in north-west Slavonia, Croatia. The compared tillage systems were as follows: conventional tillage (CT), reduced conventional tillage (RT), conservation tillage I (CP), conservation tillage II (CM), no-tillage system (NT). The aim of the research was to determine the influence of those tillage systems on the energy and labour requirement, and on the yield of the maize and of the winter wheat. Comparing the energy requirement to CT system, RT system required 16.1% less, CP system 26.9% less, CM system 40.8% less, while NT system required even 85.1% less energy per hectare. The labour requirement showed that RT system saved 16.4%, while CP system required 20.5% less, CM system 39.5% less labour respectively. NT system saved 82.1% of labour in comparison to CT system. The first year greatest maize yield of 7.78 Mg ha-1 was achieved with CT system, while other systems in comparison to CT system, except RT, achieved not significantly lower yields. The second year greatest winter wheat yield of 5.89 Mg ha-1 achieved CM system, while other systems in comparison to CM, except RT, achieved not significantly lower yields.

Soil tillage promotes changes in soil structure. The magnitude of the changes varies with the nature of the soil, tillage system and soil water content and decreases over time after tillage. The objective of this study was to evaluate short-term (one year period) and long-term (nine year period) effects of soil tillage and nutrient sources on some physical properties of a very clayey Hapludox. Five tillage systems were evaluated: no-till (NT), chisel plow + one secondary disking (CP), primary + two (secondary) diskings (CT), CT with burning of crop residues (CTb), and CT with removal of crop residues from the field (CTr), in combination with five nutrient sources: control without nutrient application (C); mineral fertilizers, according to technical recommendations for each crop (MF); 5 Mg ha-1 yr-1 of poultry litter (wetmatter) (PL); 60 m³ ha-1 yr-1 of cattle slurry (CS) and; 40 m³ ha-1 yr-1 of swine slurry (SS). Bulk density (BD), total porosity (TP), and parameters related to the water retention curve (macroporosity, mesoporosity and microporosity) were determined after nine years and at five sampling dates during the tenth year of the experiment. Soil physical properties were tillage and time-dependent. Tilled treatments increased total porosity and macroporosity, and reduced bulk density in the surface layer (0.00-0.05 m), but this effect decreased over time after tillage operations due to natural soil reconsolidation, since no external stress was applied in this period. Changes in pore size distribution were more pronounced in larger and medium pore diameter classes. The bulk density was greatest in intermediate layers in all tillage treatments (0.05-0.10 and 0.12-0.17 m) and decreased down to the deepest layer (0.27-0.32 m), indicating a more compacted layer around 0.05-0.20 m. Nutrient sources did not significantly affect soil physical and hydraulic properties studied.

Field experiments were conducted to determine the effects of tillage systems and varieties on growth, yield and quality of wheat crop (Triticum aestivum L.). The experiments conducted at two sites were laid out in a split-plot design with four replicates, three main plots [conventional tillage (CT), no-tillage (NT) and minimum tillage (MT)] and four sub-plots (‘Siette’, ‘Panifor’, ‘Myrto’, ‘Estero’). The soil porosity and total nitrogen were higher in soils subjected to conservation tillage systems (NT and MT) than under conventional tillage. There were no differences in root growth neither between the tillage systems nor among the varieties. Yield was influenced by the tillage system and variety. The highest grain yield (421-459 kg ha-1) was found under the CT system with ‘Siette’, ‘Myrto’ and ‘Estero’ varieties. In contrast, the highest grain yield was observed under conservation tillage (NT and MT) with ‘Panifor’ variety. There were no significant differences between the tillage systems concerning the protein content and Zeleny value. In contrast, the highest Hagberg falling number was found with MT. Zeleny value was positively and significantly correlated with protein content. High flour quality, as demonstrated by high protein content and Zeleny value, and low Hagberg falling number, was produced in the ‘Estero’ variety.

The Ap horizons of two conservation tillage studies on Dark Brown Chernozemic soils in southern Alberta were sampled in 1986 following the fallow year. The first study, started in 1967, consisted of a wheat-fallow rotation under either no-till chemical fallow, blade-cultivate, or chemical fallow + blade-cultivate management. The second study, started in 1977, consisted of continuous winter wheat, winter wheat-barley-fallow, and winter wheat-fallow rotations under either no-till or conventional tillage management. Nine years of no-till continuous wheat and 19 yr of no-till in a wheat-fallow rotation both led to 40% of the dry aggregates being > 0.84 mm in diameter. The parameters selected helped to characterize differences in organic matter between soil tillage systems. Dehydrogenase and phosphatase activities were twice as high under no-till as under the blade-cultivate treatment. No-till also led to the largest monosaccharide accumulation in the soil. Carbohydrates, solvent-extractable organic matter, and chitin N were significantly higher in the > 0.84 mm diameter dry aggregates from the no-till treatment. The monosaccarides under the blade-cultivate regime were generally of microbial origin whereas those under the no-till regime were generally of plant origin.

Spring barley can be used to diversify and intensify winter wheat-based production systems in the U.S. Pacific Northwest. The objective of this study was to describe the effects of tillage system and weed management level (WML) on weed control and spring barley grain yield when grown in a winter wheat-spring barley-spring dry pea rotation. A long-term integrated pest management field study examined the effects of three WMLs (minimum, moderate, and maximum) and two tillage systems (conservation and conventional) on weed control and barley grain yield. Total weed biomass at harvest was 8.0 and 59.7 g m−2for the maximum and minimum WMLs, respectively, in the conservation tillage system, but was similar and averaged 12.2 g m−2for all three WMLs in the conventional tillage system. Despite greater weed biomass with minimum weed management in the conservation tillage system, barley grain yields averaged 5,060 and 4,780 kg ha−1for the conservation tillage and conventional tillage systems, respectively. The benefits of conservation tillage require adequate herbicide inputs.

The aim of the paper is to determine the effect of water erosion on maximum capillary water capacity, bulk density, soil airiness, total porosity and minimal air capacity. For this purpose, 13 plots located in South Moravia were selected. Each plot was divided into three positions. The first one, eluvial, was located on the top of the slope. These were always flat and water erosion did not occur there. The second one was midslope position where soil was damaged by water erosion. Soil washed down from the midslope position was accumulated in the third one. It has been found that water erosion has a statistically significant effect on minimal air capacity of topsoil, and on bulk density and airiness of subsoil. Variance analysis showed less variance of values​​ referring all characteristics beyond these: the minimal air capacity of the midslope position damaged by erosion regarding topsoil; and maximum capillary water capacity, soil airiness and porosity regarding the subsoil.

Plants of spontaneous flora are in constant competition with culture plants for water, nutrients and other vegetation factors. The degree of weeding was determined in 2014-2016, at four crops - winter wheat, maize, soybeans and peas, cultivated in conventional tillage system and conservation tillage. Temperatures and precipitations registered on the vegetation period in three year had a high influence on the number of weeds found in agricultural crops, so in 2015 there was a smaller number of weeds than in 2014 respectively 2016. Of the species determined in this period is noted for annual dicotyledonous (most of them Chenopodium sp., Veronica sp. and Xanthium strumarium), and among the species of monocotyledonous species Echinochloa sp. and Setaria sp. which are found in all four cultures. In the case of the application of conservative tillage systems there is an increase in the number of weeds compared to the conventional tillage system. The average yields obtained by maize, soybean and peas at application of conservative tillage systems are close to the classical tillage system, the winter wheat yield was higher in the no tillage system than in the classical tillage system.

The current study investigated the effect of water quality (the salinity of the irrigation water) and Tillage system on some soil physical properties. The experiment was carried out using RCBD with three replicates. wheat was irrigated by three water sources, a  river ,dranege and well waters with electrical conductivities  1.3, 3.5 and 6.9 ds.m-1 respectively and three tillage systems were zero tillage (ZT), conventional tillage (CT) and deep tillage (DT). After harvest, some soil physical properties were evaluated including: bulk density, porosity, penetration resistance, hydraulic conductivity and mean weight diameter. The result showed that the bulk density values were 1.40, 1.44 and 1.47 mg.m-3  for river, derange and well water. while the porosity values were 47.3%, 45.8%  and 43.8%. for river, derange and well water. while the hydraulic conductivity  were 5.13, 4.26 and 4.36 cm.h-1for river , derange and well water. also the result showed that the bulk density values were 1.48, 1.44 and 1.38 mg.m-3 for ZT, CT and DT respectively. while the porosity values were 44.3, 45.7 and 47.8% for ZT, CT and DT respectively. But for the interactions for electrical conductivity with tillage The result showed that the bulk density values were 1.50 mg.m-3  for well water with ZT but decrees value it become 1.34 mg.m-3  for river water with DT. The best type of tillage was conventional tillage as it has the ability to improve properties of soil as well as it helps to reduce.

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.
