The blind pursuit of high yields via increased fertilizer inputs increases the environmental costs. Relay intercropping has advantages for yield, but a strategy for N management is urgently required to decrease N inputs without yield loss in maize-soybean relay intercropping systems (IMS). Experiments were conducted with three levels of N and three planting patterns, and dry matter accumulation...
Objective: For investigation of intercropping of maize and faba bean, an experiment was conducted in Research Station of Agriculture Faculty of Tabriz University during growing season of 2013. Methods: Experimental design was randomized complete block design with three replications and seven treatment. Treatments included one row intercropping (1:1), 4 strip intercropping pattern with ratios of...

a field experiment was conducted at research station of zabol university in 2012. the experiment carried out as split plot on basis of a randomized complete block design with three replications. the main and sub factors included tillage systems (no, reduced, and conventional tillage) and planting ratios of intercropping (pure culture of roselle, pure culture of green gram, 25% roselle + 75% gre...
Traditional farming practices suggest that cultivation of a mixture of crop species in the same field through temporal and spatial management may be advantageous in boosting yields and preventing disease, but evidence from large-scale field testing is limited. Increasing crop diversity through intercropping addresses the problem of increasing land utilization and crop productivity. In collabora...
introduction sustainability of agricultural systems may improve due to intercropping as a result of diversity increasing. marigold (calendula officinalis) is a major medicinal plant from asteraceae family, though weeds suppress it because of lower competitiveness against weeds. mungbean (vigna radiata) is a pulse crop from fabaceae family and is one of the major nutritive sources especially in ...
To evaluate the advantage of chickpea-barley intercropping systems under weed interference conditions, an experiment was conducted at the Agricultural Research Station, Faculty of Agriculture, University of Bu-Ali Sina, during 2010 growing season. Experiment was conducted as split plot base on randomized complete block design with three replications. Weed control treatment at two levels of weed...
intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...
introduction intercropping as a common method in sustainable agricultural systems, plays an important role in increasing productivity and yield stability to improve utilization of resources )alizadeh et al., 2010). studies in different countries showed that intercropping causes increase in diversity, production and more efficient use of water resources, land, labor and nutrients and also reduce...
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 ...
