One of the effective steps in use of water resources is accurate estimation of plants water requirement. Lack of accurate estimation of this amount leads to water loss and failure to achieve optimum yield, reduced potential of production, soil resources degradation by too much irrigation or lack of enough leaching and salinization of soils by irrigation less than necessary level, which would ul...

Weed management is a major issue in organic farming systems. Although interseeding cover crops is one alternative to herbicides, cover crops often suppress not only weeds but also main crops. Therefore, using cover crops for weed control without adverse effects on main crop growth is important. To verify the effect of cover crops on competition between main crops, cover crops and weeds in snowy...

Cover crops are often defined as crops grown for the protection and enrichment of the soil. They are sometimes referred to as green manures or living mulches because if the definition is expanded a bit they are crops grown to suppress weeds, build productive soils and help control pests and diseases. Cover crops can be soil builders, soil looseners, soil water conservers, erosion fighters, nutr...

Pharmaceutical crops is an ambiguous term used by biologists and chemists for different categories of plants. This review focuses on the definition and scope of pharmaceutical crops. We define pharmaceutical crops as those cultivated species that are used for extraction or preparation of therapeutic substances such as active pharmaceutical ingredients (APIs), excipients used in pharmaceutical f...

The adoption of transgenic crops (also called GMOs and biotech crops) worldwide has been rapid and impressive, reaching 120 million ha in 2008, and continues to grow at a steady pace (James, 2008). Approximately 80% of the total area devoted to these crops has been planted with herbicide-resistant crops, virtually all being glyphosate-resistant (GR) crops. Thus, a single genetic trait—glyphosat...

The European Energy Crops Overview (EECO) project was carried out with 20 partners from fourteen EU countries during 1996. The EECO-project provides the state-of-the-art on energy crops activities in Europe. More than 30 potential energy crop species have been investigated in Europe, but only a few have achieved commercial status so far. The introduction of energy crops in agriculture is relati...

This research through comparison study of application of ICT on marketing of agricultural crops in khozestan province, evaluate the role of such factors. The study is of applied type and the method being used is descriptive- correlational. Statistical population of this research is all agricultural experts of Khuzestan province and using Cochran’s formula , a sample size of 144 members was sele...

Cover crops are important components of sustainable agricultural systems. They increase surface residue and aid in the reduction of soil erosion. They improve the structure and water-holding capacity of the soil and thus increase the effectiveness of applied N fertilizer. Legume cover crops such as hairy vetch and crimson clover fix nitrogen and contribute to the nitrogen requirements of subseq...

Political responses to novel foods and crops can be specific to the new traits of those crops (agronomic versus enhanced nutrients), to the intended uses of those crops (food for people versus feed for animals), and also to the methods used to introduced those traits (conventional breeding versus genetic engineering). This article describes variations in observed political responses to three di...

Great progress has been made over the past decade with respect to the application of biotechnology to generate nutritionally improved food crops. Biofortified staple crops such as rice, maize and wheat harboring essential micronutrients to benefit the world's poor are under development as well as new varieties of crops which have the ability to combat chronic disease. This review discusses the ...
