To compare the replacement intercropping patterns of fennel (Foeniculum vulgare Mill.) and faba bean (Vicia faba L.) at different levels of vermicompost, a field experiment was conducted as factorial arrangement in randomized complete block design with three replications at the research field of the Faculty of Agriculture, Urmia University, Iran, in growing season of 2018. Experimental treatmen...

A review of organic growers' concerns about weeds is presented and several issues that may ease those concerns are highlighted. The underlying principles of organic weed management (OWM) are briefly discussed and results from organic grower surveys regarding weed management practices in organic horticultural cropping are presented. The most common weeds encountered by organic growers, often tho...

the recent decades emphasis on reducing pesticide use especially herbicide has led to increased interest in alternative weed control methods. the purpose of this study was to evaluate the hilling time and simultaneous interseeding of two cover crops as living mulch to control weeds in potato and to determine the impact of these actions on potato yield. a randomized complete block design as spli...

The ongoing climate change, coupled with the transformations of cultivation practices and land use in sole crop production, may cause a significant decline sunflower yield stability. Considering that is third oilseed world market, 45 million tons grain per year, it takes fourth position vegetable oil implementation sustainable growing technology production necessity. above, goal research was to...

Numerous plant species are considered weeds in agronomic cropping systems. Weeds have many attributes undesirable to crop producers, not the least being the ability to reduce crop yields through competition for resources such as sunlight, water, nutrients, and space. Weeds also may harbor insects and provide a host for certain plant pathogens. Some weed species, such as wild garlic and eastern ...

<span>Intensive dairy farming systems in the sandy soil of northwestern Morocco are based on three successive forage crops per year, including corn. The aim was to evaluate productivity and quality different intensive crop successions corn soil. Three year (winter, spring, summer cropping seasons) were tested according six successions: 1. fallow-corn-corn, 2. oat-corn-corn, 3. berseem-cor...

Intercropped corn (Zeu mays L.) and soybean [Glycine mux (L.) Merr.] may produce more total yield per hectare than either grown separately, ie., land equivalent ratio (LER) >l. Low N fertility, limited moisture, and weed competition have each been reported to result in high land equivalent ratios. Thus it was hypothesized that intercropping advantages were greater under stress conditions. The o...
