Intercropping is widespread in small-holder farming systems in tropical regions and is also practiced in the cultivation of indigenous vegetables, to alleviate the multiple burdens of malnutrition. Due to interspecific competition and/or complementation between intercrops, intercropping may lead to changes in plants accumulation of minerals and secondary metabolites and hence, alter nutritional...

With increasing economic and environmental costs associated with fertilizer use, the need for low-input agroecological systems is on the rise. It is well documented that intercropping legumes can increase the supply of nutrients, through N2-fixation and P mobilization. Concurrently, the integration of trees in the agricultural landscape shows increasing evidence of nutrient inputs through effic...

in order to evaluate the yield and nitrogen use efficiency of corn and cotton intercropping under different levels of nitrogen, an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications. the experimental treatments were nitrogen fertilizers in four levels (0, 50, 100 and 150 kg ha-1) and planting pattern in three levels (maize sol...

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) ...

To assess the suitability of Leguminous species in rice intercropping systems, physiological and morphological characteristics of Crotalaria juncea, Cajanus cajan, Mucuna pruriens var. cochinchinensis, Calopogonium mucunoides, Aeschynomene histrix and Stylosanthes hamata were determined in monoculture. C. cajan and S. hamata were selected and intercropped with two upland rice cultivars (WAB56-5...

The economical analysis complements the evaluation of the intercrop systems efficiency, considering besides the physical production of crops, the price of products according to their quality classification and time of the year. Intercropping systems of lettuce and cucumber in two plant populations under greenhouse were economically evaluated in winter-spring, in Jaboticabal City, São Paulo Stat...

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...

This research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. To do this a split plot experiment carried out based randomized complete block design with three replications in research field of Shushtar Islamic Azad University. The main plot included three level...

The technique of farming two or more crops in the same field at time is known as intercropping. It has been practiced for decades. provides a number benefits, including efficient and effective resource utilization, less soil erosion, increased yield output on limited cultivated field, risk reduction smallholder farmers, higher income per unit work during times labor scarcity. Intercropping legu...

The tripartite symbiosis between legumes, rhizobia and mycorrhizal fungi are generally considered to be beneficial for the nitrogen (N) uptake of legumes, but the facilitation of symbiosis in legume/non-legume intercropping systems is not clear. Therefore, the aims of the research are as follows: (1) to verify if the dual inoculation can facilitate the N uptake and N transfer in maize/soybean i...
