in order to effects of fertilizer source and intercropping ratios on macronutrients concentration and uptake of fenugreek and black cumin, a factorial experiment was conducted as randomized complete block design with three replications at shahrekord university research farm in 2013. sole cropping of fenugreek (f) and sole cropping of black cumin (b) and three intercropping ratios (f:b 2:1, f:b ...

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...

Mycorrhizal associations contribute to the sustainability of crop production systems through their roles in nutrient cycling and other benefits in the soil-plant ecosystems. A two-year study was conducted on the Alfisols of Lilongwe and Dowa districts, Central Malawi, to assess the vesicular-arbuscular mycorrhizal (VAM) fungal colonisation levels in pigeon pea, cowpea, and maize grown in sole c...

increasing diversity and apply intercropping systems is one of approaches to control of weeds. to evaluate the effects of additive maize-bean intercropping on yield, yield components and weeds in zanjan conditions, a field study was conducted in a spilt plot with randomized complete block design in three replications at research farm of zanjan university in 2010. main plots were the different p...

Okro and Peppper were intercropped in a randomised complete block design with three replicates to assess the effect of this on the population of several insect pest of Okro. Five pests of Okro were recorded: Podagrica uniforma; Podagrica sjostedti; Oxycarenus hyalipennis; Cosmophila flava and Dysdercus superstitiosus. However, there were no significant difference in the population of these inse...

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...

In order to evaluate the yield, yield components and protein contents of two wheat cultivars (Zarrin and Gaspard) in sole cropping and intercropping systems,an experiment was conducted using replacement serious technique and different combinations of intercropping with high plant density and optimal of each cultivar. A factorial experiment was conducted in the form of randomized complete block ...
