in order to study of no-tillage, reduced tillage and conventional tillage systems on some soil physical properties, yield and some traits of wheat and chickpea, experiments were perfumed across two years in sarpolezahab’s dryland region.results of combined analysis of variance indicated that different tillage systems had significant effects (p≥0.01) on seed yield, volumetric soil moisture, bulk...

This study was designed to investigate the effects of different tillage systems on some parameters such as soil salinity (pH, EC, SAR), soil density and nutrients in a nested experimental design with three treatments (no tillage, reduced tillage and conventional tillage) and three replications. Chenaran city fields were selected as the case study areas. Result of the statistical analysis indica...

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 ...

abstract methods of tillage and organic matter affect root growth and distribution and therefore nutrient uptake by plant and its growth. this study was performed consecutive two years. tillage treatments included disk harrowing + two disk harrowings as reduced tillage (15 cm plowing depth) and moldboard plowing + two disk harrowings as conventional tillage system (30 cm plowing depth). also, t...

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...

high intensity evaporation from the soil surface due to low air humidity and poor soil structure and organic matter are constraints of agriculture in arid and semi-arid regions of iran. regionally, maintaining plant residue with tillage management is one method to improve these conditions. in this study, for a barley-corn rotation, four barley residue management methods for standing stubble (bu...

The experiments were conducted at Green Acres Agronomy farm near Gainesville, Florida, on an Arredondo loamy sand, a member of the loamy, silicious, hyperthermic family of grossarenic Paleudults. The field study started in 1976 included cropping systems of oat (Avena sativa)/soybean (Glycine max L. Merr.) versus oat/grain sorghum (Sorghum bicolor L.) that were split plots of four tillage treatm...
