Agriculture is the single biggest user of land and water in Morocco; however its performances are still low due to high rainfall variation and rates of soil productivity depletion. Increasing concerns about soil and environment quality degradation have raised the need to review existing tillage management systems and develop new systems for seed-bed preparation. Consequently, No-tillage is foun...

A series of field experiments was conducted at BARI central farm to observe the changes in soil densities, moisture retentive properties, and crop productivity as influenced by different tillage depths and cropping patterns. The tillage depth showed significant effect on wheat yield. Grain yield of wheat significantly increased from 2.86 t/ha (minimum tillage depth) to 5.33 t/ha (tillage depth ...

Adoption of sustainable tillage can protect soils from biological degradation and maintain soil quality, as compared with conventional management. This paper presents findings from a long-term tillage experiment carried out in Endocalcari-Endohypogleyic Cambisols on a sandy loam soil in Lithuania. The tillage systems were: conventional (CT), moderate (MT), and no tillage (NT). Tillage intensity...

this study was conducted in the research field of iranian research institute of plant protection in karaj as strip split plots with three replications. the first factor: tillage and no-tillage, and the second factor: herbicide: glyphosate 6 l/ha, 2,4-d + mcpa 2l/ha, glyphosate + 2,4-d + mcpa (6 + 2 l/ha), glyphosate 3 l/ha, 2,4-d + mcpa 1 l/ha, glyphosate + 2,4-d + mcpa (3 + 1 l/ha), and contro...

This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...

Two field experiments were conducted for two years with the aim of studying the effects of deep tillage and straw returning on soil microorganism and enzyme activity in clay and loam soil. Three treatments, (1) conventional tillage (CT), shallow tillage and straw returning; (2) deep tillage (DT), deep tillage and straw returning; and (3) deep tillage with no straw returning (DNT), were carried ...

A major challenge for agriculture is to enhance productivity with minimum impact on the environment. Several studies indicate that cover crops could replace anthropogenic inputs and enhance crop productivity. However, so far, it is unclear if cover crop effects vary between different cropping systems, and direct comparisons among major arable production systems are rare. Here we compared the sh...

Effect of haying (hayed or not hayed prior to tillage), tillage (notillage, minimum tillage, or conventional tillage), and N fertilization (0 or 67 kg ha ') on surface infiltration rates, Q(h), was evaluated for Conservation Research Program (CRP) site conversion. Soils included Amor loam (fine-loamy, mixed, superactive, frigid Typic Haplustoll) and Cabba silt loam (loamy, mixed, superactive, c...

paddy rice residue covers more than 60000 ha of the khuzestan plain. high soil moisture content (low evaporation and heavy soil texture), time limitations, and the likelihood of rainfall make conventional tillage methods unsuitable for wheat cultivation after the rice harvest. the present study investigated the best residue management method, and fuel and time savings, to produce acceptable yie...

The weed seed bank of a long-term tillage study in subarctic Alaska was studied at the end of 10 years of continuous spring barley (Hordeum vulgare L.). Tillage treatments were: no-till, disked once (spring), disked twice (spring and fall), and chisel plow (fall). Soil cores were obtained from each tillage treatment and seeds were manually separated from soil after washing through sieves. Tilla...
