Functioning of plant-aphid-natural enemy interactions may be associated with the structure and composition of withinfield vegetation, neighborhood fields and field borders, and the regional plant community of cropped and noncropped areas. Farmand region-scale vegetation in the wheat-growing area of the North American Great Plains was hypothesized to effect the abundance of two hymenopteran para...

The objective of this study was determining the most limiting plant growth factor in the wheat root zone dominated by illite in clay fraction and a high specific surface with ample ammonium acetate extractible potassium. A completely randomized block design with 4 replicates was used in Seyed Miran Research Farm (Gorgan) during 2009-2010 growing season. Treatments were mineral fertilizers (to a...

In order to determine the best intercropping combination of wheat (Triticum aestivum) and rapeseed (Brassica napus) based on total yield and landuse efficiency, an experiment was conducted during 2010-2011 growing season at Agricultural Research Farm of Faculty of Agriculture, Bu-Ali Sina University. This experiment used randomized complete blocks design and three replications. Treatments inclu...

ABSTRACT- Crop rotation has many benefits for agro-ecosystems production. In order to evaluate two current rotation systems of wheat (Triticum aestivum L.) production in Kamalabad region of Fasa, an experiment was conducted during 2015-2016 growing season. The rotation systems were fallow-wheat and cotton (Gossypium spp.)-wheat. Research plots were arranged as a randomized complete block design...

In recent years, special attention has been paid to the consumption of plant growth stimulants such as amino acids and humic acids along with micronutrients to adjust the effects of abnormal environmental conditions such as untimely cold or salinity and drought stress in grain production programs. In order to investigate the effect of growth enhancers on compensating for the lack of transport a...

An experiment was conducted to examine the digestible energy (DE) content for weanling pigs in a cohort of wheats grown in Western Australia, and to establish relationships between DE content and their chemical composition. The 3 ✕ 3 ✕ 2 factorial experiment examined the wheat variety (Arrino, Stiletto and Westonia), growing location (high, medium and low rainfall zone) and harvest year (1999 a...
