Preand postharvest contamination of aflatoxin in maize is a major health deterrent for people in Africa where maize production has increased dramatically. This chapter highlights management options for preand postharvest toxin contamination in maize. Sound crop management practices are an effective way of avoiding, or at least diminishing, infection by Aspergillus jlavus and subsequent aflatoxi...

globally, irrigated agriculture is the largest extractor and the most frequent consumer of groundwater resources, with important groundwater-dependent and largely spread agro-economies. quality of irrigation water is one of the key factors which have either direct or indirect impact on plant growth, soil and water management practices and plant yields. this work aims at highlighting the importa...

BACKGROUND Conservation practices often associated with glyphosate-resistant crops, e.g. limited tillage and crop cover, improve soil conditions, but only limited research has evaluated their effects on soil in combination with glyphosate-resistant crops. It is assumed that conservation practices have similar benefits to soil whether or not glyphosate-resistant crops are used. This paper review...

Many eastern Arkansas producers who typically grow soybean (Glycine max L.) in a wheat (Triticum aestivum L.)-soybean double-crop system choose to burn wheat residue immediately after harvest as a means of seedbed preparation. Burning residue adds a considerable amount of carbon dioxide (CO2) to the atmosphere and prevents the return of much needed carbon (C) to the soil. Alternative wheat-resi...

China and other rapidly developing economies face the dual challenge of substantially increasing yields of cereal grains while at the same time reducing the very substantial environmental impacts of intensive agriculture. We used a model-driven integrated soil-crop system management approach to develop a maize production system that achieved mean maize yields of 13.0 t ha(-1) on 66 on-farm expe...

Tillage selection is just one of the issues that farmers must address when making crop production decisions. Among the factors that will influence the choice of tillage for a given field is the condition of the residue and soil in the field; the residue management practices needed to meet conservation plan specifications; the tools, time, and money that are available; the need to incorporate am...

the study objects for investigating the possibility of activating both audit committee and board of directors for restricting the practices of earnings management phenomenon. to achieve this objective, a questionnaire had been developed and self-administered for a selected sample consists of 123 auditors working in jordan based on the simple random sampling method. the study first hypothesis is...

Introduction Organic farming systems are challenged by many of the same crop protection issues as conventional farming systems. Approaches to crop protection in organic agriculture differ widely among growers globally and regionally. At one end of the spectrum, organic growers use substitution-based approaches in large-scale operations to capture premium prices in a niche market. At the other e...
