plant dry matter accumulation has a linear relation with accumulative photosynthetically active radiation (par). intercropping could be a strategy for increasing light absorption in agronomic systems and it may improve radiation use efficiency (rue). thus this study was conducted in order to evaluate radiation absorption and use efficiency in potato (solanum tuberosum l.) –corn (zea mays l.) in...
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...
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...
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 investigate the effects of biological and chemical phosphorous fertilizers and various proportions of maize and grass pea intercropping on yield and yield components of both crops, two experiments were conducted simultaneously in research farm of kerman university and commercial convention farm of bardsir-dashtkar in 2009-2010. the experimental design at two regions was randomized c...
Application of intercropping systems is one of the ecological methods for controlling weeds due to maximization of soil cover and plant diversity. In order to study the effect of intercropping system of indigo (Indigofera tinctoria L.) and roselle (Hibiscus sabdariffa L.) on biodiversity, weeds population changes and plant yield an experiment was conducted based on randomized complete block des...
Intercropping has been widely used to control disease and improve yield in agriculture. In this study, maize and peanut were used for non-separation intercropping (NS), semi-separation intercropping (SS) using a nylon net, and complete separation intercropping (CS) using a plastic sheet. In field experiments, two-year land equivalent ratios (LERs) showed yield advantages due to belowground inte...
Intercropping and N fertilization play an important role in increasing crop yield. In order to further understand the advantage mechanism of intercropping and the effect of increasing N application on the advantage effect of intercropped crop, a field experiment was conducted to investigate the effects of different cropping patterns (i.e. M, maize monoculture; I1, maize-cotton intercrop; I2, ma...
to evaluate the yield and quality of barley (hordeum vulgare)–vetch (vicia desycarpa) intercropping, a series of experiments were conducted at the experimental field of the college of agriculture, university of tehran, in karaj (iran) from 2003 to 2005. the ex-periments were arranged in a randomized complete block with a split plot design and four replications. three levels (0, 45 and 90 kg n h...
