in the absence of herbicides, cover crops play an important role for weed management in organic than in conventional farming. therefore, in order to evaluate the effects of cover crop management and plant density of buckwheat (fagopyrum esculentum) as cover crop on weed suppression, a field experiment was conducted at the research farm of university of zanjan, during the growing season of 2011....

The objective of the study was to evidence efficient management strategies in order maximize soybean grain yield. experiments took place at Centro de Pesquisas e Resultados Agronômicos das Missões (CPRAM), located Entre - Ijuís Rio Grande do Sul, Brasil. Three were carried out a randomized block design with four replications per treatment. based on crop management. Soil cover vetch enhanced cul...

there are many methods for weed management one of them is putting allelopathic and cover crop in weed management programs. in order to study the effect of sowing time (delayed sowing, synchronic sowing) and wheat cultivars (shiraz, roshan, tabasi, niknejad) on allelopathic interaction of wheat and weed species (secale cereale l., avena ludoviciana l.: monocotyledon, convolvulus arvensis l. and ...

Understanding ecophysiological characteristics of corn (Zea mays L.) under winter cover crops (WCCs) can improve management and farmers’ acceptance by increasing the positive effects and decreasing the negative effects associated with their use. This study was conducted to quantify the effects of WCC on corn development, growth, and yield through the evaluation of ecophysiological characteristi...

Understanding cover crop and tillage system interactions within specific environments can help maximize productivity and economic returns of cotton (Gossypium hirsutum L.) produced on sandy coastal plain soils of the southeastern USA. A strip-plot design with three replications was used to evaluate the cover crops Austrian winter pea [Pisum sativum L. ssp. arvense (L.)], balansa clover (Trifoli...

to evaluate the yield and quality of barley (hordeum vulgare)–vetch (vicia desycarpa) intercropping, a series of experiments were conducted at the experimental field of the college of agriculture, university of tehran, in karaj (iran) from 2003 to 2005. the ex-periments were arranged in a randomized complete block with a split plot design and four replications. three levels (0, 45 and 90 kg n h...
