This paper aimed to study the effect of temporary cover crop and vine pruning residue burial as alternative practices conventional tillage on soil nitrate (NO3-N) availability grapevine performance in short term. The trial was carried out a rain-fed vineyard (Vitis vinifera L., cv Grecanico dorato/140 Ruggeri) located traditional Mediterranean viticultural area (37°32?48?? N; 13°00?15?? E) Sici...

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...

This paper identified the factors influencing the rice crop residue burning decision of the farmers and the potential of the burnt residue to generate electricity. For this study, data were collected from 400 farmers in the rice-wheat cropping system. Effects of different variables on the burning decision of rice residue are investigated through logit model. A number of factors had significant ...

In Cambodia, cassava is mostly grown with little or no fertilizer inputs, but the magnitudes of nutrient balances are not known. This study was conducted to assess nutrient balances for cassava cultivation in Kampong Cham province in Northeast Cambodia. Forty five households in four cassava production zones were interviewed in relation to their cultural practices and crop residue management...

L.) are now grown with winter wheat and fallow. Integrating crop diversity with other cultural tactics enabled No-till systems have enabled producers to change crop rotations in producers to effectively control weeds with 50% less the semiarid Central Great Plains. Previously, winter wheat (Triticum aestivum L.)–fallow was the prevalent rotation; now producers grow herbicide inputs compared wit...

Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...

Removal of corn residue for biofuels can decrease soil organic carbon1,2 (SOC) and increase CO2 emissions3 because residue C in biofuels is oxidized to CO2 at a faster rate than when added to soil.4,5 Net CO2 emissions from residue removal are not adequately characterized in biofuel life cycle assessment (LCA).6–8 Here we used a model to estimate CO2 emissions from corn residue removal across t...

introduction weeds deprive the crop plants from limited available nutrients, space, light, and moisture. hence, the physiological activities and growth of crops are negatively affected in the presence of weeds. ultimately, poor crop productivity is the result of weed-crop competition. allelopathy is primarily based on the ability of certain plant species to produce secondary chemical compounds...
