Ovipositional preference and larval survival of the diamondback moth, Plutella xylostella (L.), were compared among cabbage, Brassica oleracea L. variety capitata; glossy collards, Brassica oleracea L. variety acephala; and yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata in different treatments of planting density, host plant age, intercropping, and water stress in 2003 and 2004. P. x...

The resource capture approach developed by John Monteith has been applied in studies of a wide variety of plant species and cropping systems in the tropics over the past 18 years. The purpose of this review is to highlight the progress made and the new challenges which lie ahead. The foundation for this approach was the establishment of ‘response surfaces’ for the development and growth of trop...

Plant disease can be effectively suppressed in intercropping systems. Our previous study demonstrated that neighboring maize plants can restrict the spread of soil-borne pathogens of pepper plants by secreting defense compounds into the soil. However, whether maize plant can receive benefits from its neighboring pepper plants in an intercropping system is little attention. We examined the effec...

Multiple cropping (i.e. intercropping or mixed cropping) plays an important role in agriculture because of the effective utilization of resources, significantly enhancing crop productivity compared with that of monocultured crops. The study was planed to assess the effect of various concentrations (00, 30, 60, 90 kg ha(-1)) of phosphorous on the biochemical composition of grains of Hordeum vulg...

intercropping is one of the management methods for crop production and leads to improvement of resource absorption and use by plants. based on this purpose the present field study was conducted to evaluate radiation absorption and uses efficiency in corn and bean strip intercropping at the farm of the faculty of agriculture, ferdowsi university of mashhad, iran during 2009. the experiment was s...

abstract to find out how maize and potato can grow and develop in an intercropping system rather than each grown alone in a sole cropping system the following factorial experiment was performend in the frame-work of a randomized complete block three replications in the experimental farm of the faculty of agriculture, zanjan university in year 2004. different potato to maize ratios of (1:0), i.e...

Intercropping has been advocated as an environmentally benign method to suppress weeds in agriculture. However, it is not evident from the literature what size of weed suppressive effect achieved on average by intercropping, and how species choice crop management affect this effect. We conducted a global meta-analysis published data quantify intercropping biomass annual arable intercrops grown ...

introduction intercropping, the agricultural practice of cultivating two or more crops in the same space at the same time, is an old and commonly used cropping practice which aims to match efficiently crop demands to the available growth resources (agegnehu et al., 2006; dhima et al., 2007). intercropping of chickpea with linseed reduced the chickpea yield by 60.3%, although linseed occupied on...

introduction weed infestation causes an extremely reduction of crops yield. on the other hand, increasing the diversity of crops in agro-ecosystems will change the biomass distribution of weeds community, thereby reducing the number and density of different weed species. weed management in the past few decades has been in conflict with ecological principles and sustainability of the production ...
