the challenge for today's researchers and practitioners agriculture, increase productivity while maintaining or improving environmental quality (including water, soil and air) to be ¬ rapid population growth and increasing demand for food, researchers are continuing to study the management of high yielding varieties suitable for growing to escape environmental stresses in dry conditions an...

Subsoil compaction can result in unfavourable soil physical conditions and hinder the root growth of maize. The effects of deep tillage and conventional tillage on soil physical properties and root growth of maize were studied during 2010–2011 at two sites (loam at Hebi and clay at Luohe) in central China. The results showed that soil penetration resistance, bulk density, water content and root...

introduction: elimination or reduction of tillage in conservation agricultural systems has led to wide variations in germination, emergence, and growth of weeds and has caused variations in the density and diversity of weeds under such systems. maintaining crop residues on the soil surface has many potential benefits in agricultural production systems; such as reducing water and wind erosions, ...

one of the main strategy for controlling salt-affected soils is to implement proper tillage method. a field experiments was conducted to determine the effect of different tillage methods on salt distribution and wheat yield in saline-sodic soil. the experiment was laid out according to randomized complete block design with three replications. treatments were studied in the experiment including ...

Roots may respond to restrictive soil physical conditions and send signals to shoots to control plant growth. Soil mechanical resistance and aeration can be managed to improve the soil physical conditions for plant growth by using different tillage systems. The objective of this study was to quantify the influence of no-tillage and conventional-tillage systems on plant response to soil mechanic...

Many sustainable agronomical practices can be adopted to contain environmental risks of crop production and, at the same time, sustain yield and quality. In this framework, the aim of this research was to study the effects of continuous cropping (CC) and crop rotation, tillage and fertilization strategies on durum wheat (Triticum durum Desf.) production. The responses of soil properties we...

Management systems influence soil quality over time. A randomized block design in 2 (tillage system) 3 (crop rotation) factorial arrangement was laid-out to evaluate the impact of tillage and crop rotation (2002–2007) on soil quality. Conventional tillage and No-till were factored into continuous corn, corn–soybean, and corn–soybean–wheat–Cowpea systems. Ten soil cores were collected at 0–7.5, ...

A microplot experiment was conducted in soybean–wheat cropping system at New Delhi during 2010-11 and 2011-12 to study the effect of continuous or cyclic tillage, viz., conventional tillage (CT) and zero-tillage (ZT) and residue management of either soybean (SR) and/or wheat (WR) on yield performance and soil physico-chemical properties. The experiment was laid out in randomized block desi...

This study was aimed at evaluating the effect of crop rotation and various tillage systems onthe chemical and biological properties of soil in the years 2013-2015. The first order factorincluded cropping systems: a) crop rotation (pea – winter wheat – spring wheat) and b)monoculture of winter wheat, whereas the second order factor were tillage systems:1) conventional (CT), 2) reduced (RT) and 3...

Cotton (Gossypium hirsutum L.r. latifolium Hutch) is very sensitive to soil conditions. The Iuiu Valley, located in the Southwest of Bahia State in Brazil, was an important area for cotton production but an inadequate soil management for years and consequent soil quality degradation lead to the decline of the crop in the region. In an effort to reestablish cotton, this study was carried out to ...
