in order to study the intercropping of barley (hordeum vulgare l.) and faba bean (vicia faba l.) an experiment was conducted as factorial based on randomized complete block design with two factors and three replications at sari agricultural science and natural resources university during 2009. the first factor was two seed ratios include d1: 75 and 150 kg.ha-1 of faba bean and barley, respectiv...

Abstract Agricultural production is increasingly viewed as more than a source of food, feed, fiber and fuel, but also system interdependent biotic abiotic components that interact to produce ecosystem services disservices. Weeds insects are commonly non-desirable agroecosystems should be managed. However, weeds can provide benefits cropping systems, such providing resources habitat pollinators ...

The winter wheat/summer fallow rotation is the most common cropping system in eastern Oregon. It is used to store winter precipitation and control weeds. This cropping system, however, destroys soil organic carbon, reduces water infiltration and thus leads to soil erosion, and is not sustainable. Conservation tillage, annual cropping, and the introduction of alternative crops are ways to improv...

In northern Laos, rapid population growth and government policies to reduce the area under slash-and-burn systems have resulted in increased cropping intensity, which has increased weed pressure and reduced yields of upland rice. Promising alternative cropping systems include the use of weed-suppressing and multi-purpose legumes as short-term fallow crops. In this study, Stylosanthes guianensis...

in order to evaluate intercropping of barley (hordeum vulgare) and vetch (vicia vilosa ler ssp. desycarpa), two field experiments were conducted on the farm of the university of tehran, karaj, iran in 2004 and 2005. a split plot experiment based on randomized complete block design (rcbd) with four replications was used in this study. nitrogen was the main factor (0, 45 and 90) and sub plot fact...

In organic farming, as crops production is directly depending on soil quality, farmers pay attention to preserve soil ecosystem in order to benefit from better ecological services. Today, soil conservation practices, such as ploughless soil tillage and cover cropping, have gained prominence in organic cropping systems and provide for great potentials such as maintaining or increasing soil ferti...

Four experiments were carried out at the São Paulo State University, Brazil, with the aim of determining the agronomic viability of intercropping tomato and lettuce, under greenhouse conditions. The studied intercropping systems were established by transplanting lettuce at 0, 10, 20 and 30 days after transplanting (DAT) tomato and by transplanting tomato at 0, 10, 20 and 30 DAT lettuce. Intercr...

Soybean field experiments were performed to investigate the weed-suppressing effects of different tillage systems and cover crop mulches at two locations in southwest Germany during 2014 and 2015. The influence of three different tillage systems on weed control efficacy, soybean plant density, and crop yield was determined. In the no-till system (NT), two different cover crops, (rye and barley)...

Till now, herbicide seems to be a cost effective tool from an agronomic view point to control weeds. But long term efficacy and sustainability issues are the driving forces behind the reconsideration of herbicide dependent weed management strategy in rice. This demands reappearance of physical and cultural management options combined with judicious herbicide application in a more comprehensive ...
