in order to study the effects of cropping systems and mulch application in relay intercropped styrian pumpkin (cucurbita pepo l.) with chickpea (cicer arietinum l.), a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at the agricultural research station, college of agriculture, ferdowsi university of mashhad, during growing s...

Concern about NO− 3 leaching and groundwater pollution from corn monoculture has prompted an investigation of alternative production systems that reduce leaching. It is hypothesized that both intercropping and water-table control could increase N uptake and reduce the quantity of N that might be lost due to leaching. This study compared corn (Zea mays L.) with annual Italian rye-grass (Lolium m...

A pot-based experiment was conducted to investigate nutrient concentrations in cucumber plants intercropped with various amounts of green garlic. In addition, the soil nutrient contents were studied over two consecutive growing seasons. The results revealed that the accumulation of biomass and the nutritional elements nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and manganese (Mn) ...

In intercropping distance research, traditional field experiments are time-consuming and tedious, and cannot be applied to quantitative interspecific distance quickly. Therefore it has become a big concern for researchers in this field to further reduce manual operation, and more automatically and quickly get the optimal planting distance. In this paper, an optimization algorithm was applied to...

Broader environmental tolerance associated with mixed population of soybean (Glycine max Merr.) cultivars may increase soybean yield potential and play a significant role in yield stability. A field study was carried out to assess whether intercropping of two commonly used cultivars of soybean with different morphological characteristics may increase seed yield in Iran. A split-plot design was ...

Intercropping often results in increasing production than sole per unit land area, but theunderlying mechanisms are poorly understood. Plants showed different physiologicalcharacteristics in intercropping and sole. However, less information was shown the relationshipsbetween plant aboveground biomass (AB), phosphorus accumulation (PB) and remobilizationand the yield advantage. Here, field exper...
