Effect of Pulverization Tools and Deficit Irrigation Treatments on II. Machinery Group, Some Soil Physical Properties, Growth and Yield of Barley

Effect of Tillage Depths and Addition of Organic Acids on some Physical Properties and Yield of Wheat (Triticum eastvum L.)

“…The productivity of the crop, whatever its specifications, depends on agricultural service operations that are carried out according to the correct rules, which include the effect on the physical properties of the soil and the improvement of soil management to maintain the fertile content of plant growth and increase the agricultural productivity of [1]. Due to its influence on soil properties such as soil IOP Publishing doi:10.1088/1755-1315/1158/2/022018 2 compaction, aggregate stability and bulk density, porosity and moisture content, pore size distribution, salt diffusion in root zones, lack of suitable seed bed, lack of suitable seed carriers, and salt diffusion in the root zone, frequent tillage is The main cause of agricultural land degradation and some negative shifts in the topsoil lead to low productivity [2]. The production of chemical-free food for humans and animals, as well as the restoration of organic matter [3], which is lost as a result of intensive farming, have prompted a worldwide shift toward the use of organic materials of animal or plant origin as a source of fertilizer.…”

Effect of Supplemental Irrigation on Durum Wheat (Triticum durum) Crop and Water use Efficiency under a Saline Environment in the Lower Cheliff Plain

“…For the latter, a water profile is necessary (current moisture in percentage, Ha) to a depth corresponding to the rooting depth of the crop (0-20cm, during the vegetative period and 0-40cm for the reproductive period). The irrigation rate consists of bringing the actual moisture to the field capacity [11]. This method allows the yield components to develop under good water conditions [12,13].…”

The effect of different tillage systems and fertilizer combinations on wheat ( Triticum aestivum L.) growth and some of yield components and its weed Competition

“…Tillage is an important field practice because of its role in improving soil management, by breaking up the soil and mixing it to change some of its physical properties, maintaining a fertile content suitable for plant growth and raising agricultural production. The plowing also depends on the type of plow used, the depth of the plowing and the nature of the treated soil, the optimal choice of the appropriate plowing depth is of great importance in improving the physical properties of the soil, reflected on the growth and spread of roots, which results in an increase in plant productivity (Ati et al, 2015). Repeated plowing is a major cause of agricultural land degradation, the occurrence of some negative changes in the surface layers of the soil, because of its effect on soil qualities such as soil compaction, stability of soil pools, its porosity, and the lack of a suitable seedbed, as well as the spread of salts in the root zone, in addition to the problem of the weed, which compete with the crop and exploit nutrients and moisture from the soil and thus cause low productivity, therefore, many countries of the world have adopted the technology of no-till farming, because of its benefits, maintaining soil moisture, improving seedling growth, and facilitating agricultural operations, in addition to the increase in production during the seasons of scarce rain in the rainy areas (Antar, 2013).…”
