intercropping is considered for increasing and stability of yield per unit. in order to study the effects of different intercropping arrangements on sorghum and mungbean yield and to find the land use advantage in the intercropping system, an experiment was carried out based on a randomized complete block design with seven treatments and three replications at the research farm, faculty of agric...

introduction weeds are main factors reducing crops yield, especially under organic farming conditions (). it has been reported that weed populations are more in organic farming compared to conventional cropping systems, resulting in more reduction of growth and yield. although the chemical control is a fast and effective way for controlling weed populations, some negative impacts of the recent ...

in order to evaluate the yield and advantage of two- and three-species intercropping of sunflower with corn and soybean, an experiment was conducted at the research farm of faculty of agriculture of tabriz university in tabriz, iran 2011. the experiment was arranged based on randomized completely block design with 6 treatments and three replications. treatments were included the pure stand of s...

Intercropping could alleviate soil-borne diseases, however, few studies focused on the immunity of the host plant induced by the interspecific interactions. To test whether or not intercropping could enhance the disease resistance of host plant, we investigated the effect of companion cropping with potato onion on tomato Verticillium wilt caused by Verticillium dahliae (V. dahliae). To investig...

In order to investigate the effects of nitrogen fertilizer levels and intercropping ratios on yield and other morphological traits of two crops, field experiments were conducted during two years (2010-2011) in the research field of the school of Agriculture, Shiraz University, Shiraz, Iran. The study was carried out in a factorial experiment laid out based on a completely randomized block desig...

Neoplasm formation, a non-meristematic tissue growth on young field pea (Pisum sativum L.) pods is triggered in the absence of UV light and/or in response to oviposition by pea weevil (Bruchus pisorum L.). This trait is expressed in some genotypes [neoplastic (Np) genotypes] of P. sativum and has the capacity to obstruct pea weevil larval entry into developing seeds. In the present study, 26% o...

The objective of this study was to evaluate the effects of sowing procedures and the seed sowing rate of kudzu (Pueraria phaseoloides cv. ‘Comum’) in corn on corn plant development, forage dry matter production, weed infestation and soybean plant development and yield. The kudzu seeds were either broadcasted over the terrain or sown in furrows (in the main plots) at rates, in both cases, of 400...
