“…Compared to the land equivalent ratios (LER), which ranges on average from 1.3 to 1.4 in intercropping systems (Zhang et al 2007a), the RNT is 8-21% higher. It was concluded that cotton wheat relay intercropping systems utilize N less efficiently than the monocrops at the system level.…”

“…As in Experiment 1, fertilizer doses were applied evenly on strips with and without a crop. Nitrogen was applied at full dose (180 kg ha Zhang et al 2007a). In the sole wheat crop, the row distance is 20 cm, and in the sole cotton crop, row distance is 80 cm.…”

“…Wheat-cotton relay intercropping is widely practiced by farmers in the Yellow River cotton producing region of China (Zhang et al 2007a), because it meets the need of farmers to grow a profitable cash crop as well as to secure food supply. Relay intercropping enables the farmers to grow cotton, in a rotation with winter wheat, when the heat resource does not match the heat requirement of cotton if sown after harvesting winter wheat.…”

“…The interspecific competition, including above-and below-ground competition, is defined as the interaction between the two species that reduces the fitness of one or both of them (Li et al 2001) and obviously plays an important role in determining the species yields in an intercropping system (Li et al 2001;Zhang et al 2007). The species with the stronger competitiveness is generally termed the dominant species or superior competitor, and has a greater capacity to acquire resources and to occupy the superior ecological niche (Grace 1990).…”

This factorial field experiment was done based on a randomized complete block design in Urmia University, Iran, in 2013 and was repeated in 2014. Treatments included two farming systems (high input and organic) and different intercropping patterns that alternated bitter vetch (Vicia ervilia L.) and safflower (Carthamus tinctorius L.) with row ratios of 2:2, 3:2, 4:2 and 5:2. Sole cropping of bitter vetch and safflower was used as the control. In both years, the 2:2 intercropping pattern had biomass yield advantages compared to sole cropping and the other intercropping ratios, based on greater land equivalent ratio values. Safflower had higher relative crowding coefficients, competitive ratio (CR) and aggressivity (A) values than bitter vetch. High-input farming was more effective than the organic system in both years. Safflower was the superior competitor when grown with bitter vetch, and its productivity dominated the total biomass yields. Thus, intercropping of safflower with bitter vetch has the potential to improve performance with high land-use efficiency.ARTICLE HISTORY

“…Intercropping has been studied to assess its effects on the incidence of various insect species: intercropping cotton x corn (Zea mays Linnaeus) x sorghum (Sorghum bicolor (L.) Moench) x beans (Vigna unguiculata (L.) Walpers) or sesame (Sesamum indicum Linnaeus) (Gonzaga et al 1991, Lin et al 2003; cotton x alfalfa (Medicago sativa Linnaeus) (Lin et al 2003); cotton x corn (Fabião and Sousa 2007); cotton x wheat (Triticum aestivum Linnaeus) (Zhang et al 2007); cotton x wheat x alfalfa x sorghum (Phoofolo et al 2010); and cotton x fennel (Foeniculum vulgare Miller) (Ramalho et al 2012, Fernandes et al 2013.…”

Population dynamics of aphids have been studied in sole and intercropping systems. These studies have required the use of more precise analytical tools in order to better understand patterns in quantitative data. Mathematical models are among the most important tools to explain the dynamics of insect populations. This study investigated the population dynamics of aphids Aphis gossypii and Aphis craccivora over time, using mathematical models composed of a set of differential equations as a helpful analytical tool to understand the population dynamics of aphids in arrangements of cotton and cowpea. The treatments were sole cotton, sole cowpea, and three arrangements of cotton intercropped with cowpea (t 1 , t 2 and t 3 ). The plants were infested with two aphid species and were evaluated at 7, 14, 28, 35, 42, and 49 days after the infestations. Mathematical models were used to fit the population dynamics of two aphid species. There were good fits for aphid dynamics by mathematical model over time. The highest population peak of both species A. gossypii and A. craccivora was found in the sole crops, and the lowest population peak was found in crop system t 2 . These results are important for integrated management programs of aphids in cotton and cowpea.
