Strip Intercropping Effects on Yield and Yield Components of Corn, Grain Sorghum, and Soybean

Abstract

20 to 24% higher corn yields and 10 to 15% lower soybean yields in adjacent border rows. Strip intercropping of corn (Zea mays L.) and soybean [Glycine Water stress, light quality, and shading are among the max (L.) Merr.] and grain sorghum [Sorghum bicolor (L.) Moench] and soybean may be a viable alternative to monoculture cropping to factors that affect crop yields and yield components at help reduce soil erosion. Careful study of yields and yield components different growth stages. Sixty-three percent shading of can add to understanding crop performance and contribute to design soybean plants caused abscission of half the pods (Mann of more productive systems.

Eck (1986) found increases in seed number and seed weight indicate that competition for that water deficits during vegetative growth reduced resources was important in both reproductive and grain-filling periods; corn kernel number, but had little effect on weight per sorghum border-row increases in seed number suggest competition kernel.

Corn and Soybeans in a Strip Intercropping System: Crop Growth Rates, Radiation Interception, and Grain Yield Components

“…Plants of row 1 generated a second ear in 60% of the time of plants of row 1 and plants of row 12 generated a second ear 40% of the time (Table 3). Similar results were reported by Lesoing and Francis [20] and Ghaffarzadeh et al [26].…”

“…This response may be explained by findings of Lesoing and Francis [20,21] who reported that yield and its components increase as radiation interception increases. On the other hand, Andrade et al [7] and also Fisher and Palmer [22] have reported that irradiance reductions around the critical period may reduce the crop yields by 50%, whereas filling reduction may reduce yields by 25%.…”

“…Previous experiments report contrasting responses on the water stress on this yield component [20,21,26,28,29]. It is important to note that two weeks following crop blooming, the young grain does not accumulate dry weight.…”

“…However, it was not treating or topological arrangement with which the highest gain was obtained ERT or greater, since there was a depression in bean yield compared to that obtained in CSMF. The decrease of 12-55% in performance or soya bean intercropped with maize has been reported by other authors (O'Callaghan et al, 1994;Lesoing and Francis et al, 1999;Matusso et al, 2014). The revised literature suggests that this is due to interspecific competition for light, water and nutrient advantage seen in corn.…”

Effects of Intercropping on the Performance of Maize and Cowpeas in Botswana

“…Higher grain y ield under sole cowpea compared to intercropping were reported by Chemeda [24]. Co mpetition for water, nutrients and shading are probably the two factors that reduced cowpea yield under high numbers of ma ize plants in Intercrop 1 [37]. There were no significant differences in the weight of cowpea seeds between treatments.…”
