Mixed cropping (including agroforestry) often gives yield advantages as opposed to monocropping. Many criteria have been used to assess yield advantage in crop mixtures. Some of these are presented. In addition, the relative merits of replacement, additive and bivariate factorial designs are discussed. The concepts of analysis of mixed cropping are applied to an example of an alley cropping (a ...

Agroforestry systems are examples of soil exploration that is closer to the natural form forest, with intercropping several species within an area, thus being sustainable alternatives. Therefore, objective this work was evaluate weed community in agroforestry two ecosystems: solid ground and floodplain state Pará. Such collections were made eight areas, about one hectare each, cultivated system...

Wheat–chickpea intercrops are not well studied, despite the importance of these two species in increasing agricultural profitability and ensuring nutritional food security. The present study aims to assess intercropping arable system’s services under contrasting field management climate conditions. Simultaneously, this assessment focuses on most agronomic ecological indices widely used literatu...

Serial assessments of neurocognitive functioning in athletes with concussion are commonly used for return to play decisions. This study provides reliable change indices (RCIs) for computerized tests from 40 NCAA Division I collegiate athletes that suffered a sports-related concussion. The normative data that resulted from the RCIs and subsequent analyses of differences between improved and not ...

introduction intercropping plays an important role in agriculture because of beneficial interactions. intercropping of legumes and cereals is an old practice in tropical agriculture dating back to ancient civilization. cereals and other plant intercrops could substantially increase forage quantity and quality and decrease the requirement for protein supplements. intercropping of cereals and oth...

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...

in order to study yield and yield components of fennel (foeniculum vulgare mill) – fenugreek (trigonella foenum-graecum l.) in different patterns of intercropping and sole cropping, an experiment with use replacement and additive intercropping based on randomized complete block design with three replications was conducted at the research station of faculty of agriculture, zanjan university, ira...

intercropping is one of the most important approaches for sustainable agricultural production. in order to evaluate the effect of planting patterns and millet density on forage yield of millet and soybean, an experiment was conducted in the research farm of faculty of agriculture, ferdowsi university of mashhad during the 2007-2008 growing season. the experiment was performed as factorial based...
