abstract in order to evaluate the effect of different nitrogen application methods on yield and yield components of winter wheat, a field experiment with split plot arrangement in completely randomized blocks design with four replicates was conducted in 2006. basal dressing in three levels (1- with no basal dressing, 2- strip and 3- distributing nitrogen fertilizer) as main plot and top dressin...

Investigating microbial metabolic characteristics and soil organic carbon (SOC) within aggregates and their relationships under conservation tillage may be useful in revealing the mechanism of SOC sequestration in conservation tillage systems. However, limited studies have been conducted to investigate the relationship between SOC and microbial metabolic characteristics within aggregate fractio...

The objective of this study was to evaluate and compare the erosion rates generated by two types hand tools for small-scale tillage on a hillslope, using experimental tests Universal Soil Loss Equation (USLE). evaluated were conventional hoe redesigned furrowing hoe. work conducted in 145 m2 plot with an average slope 45% Colombia. Three treatments evaluated: a) Zero no herbicide (control); b) ...

This work was aimed at assessing whether in silage maize it is possible to replace precisionplanting with a volumetric seeding in the perspective of developing hybrid machines to strip tilland sow both high density crops like winter cereals and low density crops like maize. This inorder to reduce the number of machines in the farm, simplify logistics and reduce amortizationcosts. Two experiment...

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...

This experiment was designed to evaluate the effects of different levels of tomato pomace (DTP) with different multi enzymes on the performance and egg quality of laying hens at the first phase of production. In this experiment 432 hens were used in a completely randomized design in a factorial arrangement of 4×4, with four levels of tomato pomace (0, 4, 8 and 12) and different enzymes (without...

Results from a four-year field experiment were used to evaluate the effect of conventional tillage (CT) and no-tillage (NT) systems on yield, selected yield crop structure elements, weed infestation, contents fat glucosinolates in seeds winter oilseed rape (Brassica napus L. ssp. oleifera Metzg). The study proved beneficial NT system seed only during precipitation shortage growing season. In ye...

Understanding management factors driving soil biota is pivotal to improve the sustainability of cropping systems, especially given emergence new systems induced by bioeconomy. Here, we investigated combined effects tillage practices (tillage versus no-tillage) and contrasted including conventional, feed biogas on earthworm communities microbial metabolic activity diversity (using Biolog Ecoplat...

This study was aimed to the examination of the effect of tillage row spacing and bush spacing on the performance and components of Phaseou vulgaris var. (line: cos16). The investigation was conducted as cut terraces and in terms of complete random blocks in three replicates at Brujerd Agricultural Research and Natural Resources in the agricultural year 2009-2010. Here, the main terraces with th...

The effects of land use change on soil organic carbon (SOC) content have been investigated extensively. However, little research has conducted how matter (SOM) chemistry changes under different management practices, particularly with cultivation methods. Thus, in this study, we compared the various including six medium-term tillage namely no-tillage, disking, shallow cultivation, deep ploughing...
