“…Similar results have been reported by Searle et al (1981). This IS m contrast to the report by Nair et al (1979) that corn grain yield increased by 20% when intercropped with soybean. Singh et al (1986) also reported that corn grain yield increased by 15-20% when intercropped with soybean, blackgram and peanut.…”

A field experiment was conducted at the experimental farm of Khon Kaen University in 2001. The objectives of this study were to investigate growth, yield and yield components of corn, peanut, soybean and mungbean under intercropping and single cropping, as well as to assess the land use efficiency. Yield and yield components of corn was unaffected by intercropping system. In legume crops; peanut, soybean and mungbean, intercropping systems reduced the leaf area and top dry weight per plant as compared with single cropping. Grain yield of peanut, soybean and mungbean was reduced by 28%, 39% and 51 %, respectively, as compared with single cropping. The pod number per plant was the most affected by intercropping among the yield components. However, corn-legume intercropping increased land use efficiency by 48% to 66% depending on legume species. Corn-peanut intercropping gave the highest land use efficiency. The effects of light penetration and nutrient competition are discussed.

“…In nitrogen uptake study of intercropped maize and groundnut, it was observed that at low nitrogen levels, the nitrogen content of intercropped maize was higher than that of sole maize, indicating some transfer of fixed N from the groundnut to maize (Francis, 1986). Earlier studies by Nair et al, (1979) had shown that groundnut/maize intercropping system increased the nitrogen uptake and yield of succeeding wheat crop, and intercropping sorghum with groundnut reportedly reduced the nitrogen fertilizer requirement of the succeeding wheat crop by 30-84 kg N ha -1 over sole sorghum. In the case of Ghosh et al, (2007), the N requirements of wheat for a target yield of 4.0 tha -1 was 100.8 kg ha -1 after sole sorghum, which was reduced to 83 kg ha -1 after intercropping sorghum with groundnut.…”

An experiment was conducted at the Savanna Agricultural Research Institute (SARI) to determine the response of groundnut varieties to spacing with regard to nodulation and nitrogen fixation. . Based on the two year average performance, the Jenkaar variety was found to be superior in terms of nitrogen fixation. However, more benefits would be derived if the variety is established using the SP1 arrangement under sole groundnut system.

“…Searle [1] stated that corn grain yield was not affected by legume intercrop, indicating neither competitive depression nor N transfer from the legume. Nair [2] showed that intercropping corn with soybeans increased yield 19.5% when compared to monoculture corn. Scott [3] noted that corn yield increases following medium red clover (Trifolium pratense L.) were equivalent to the addition of 17 kg ha À1 fertilizer-N.…”

Many alternative management systems have been evaluated for corn (Zea mays L.), soybeans (Glycine max L.), and wheat (Triticum aestivum L.) production, however, most have involved rotations from one year to the next. Legume interseeding systems which employ canopy reduction in corn have not been thoroughly evaluated. One such study was initiated in 1994 at the Panhandle Research Station near Goodwell, OK, on a Richfield clay loam soil, to evaluate five legume species interseeded into established corn: yellow sweet clover (Melilotus officinalis L.), subterranean clover (Trifolium subterraneum L.), alfalfa (Medicago sativa L.), arrowleaf clover (Trifolium vesiculosum L.), and crimson clover (Trifolium incarnatum L.). In addition, the effect of removing the corn canopy above the ear (canopy reduction) at physiological maturity was evaluated. Canopy www.dekker.com 1335 reduction increased light interception beneath the corn thus enhancing legume growth in late summer, early fall, and early spring the following year prior to planting. Forage growth from legumes incorporated prior to planting were expected to lower the amount of inorganic nitrogen (N) fertilizer needed for corn production. Crimson clover appeared to be more shade tolerant than the other species, and interseeding this species resulted in the highest corn grain yields when no N was applied. In the last two years, interseeding crimson clover at physiological maturity, followed by canopy reduction resulted in a 1.32 Mg ha À1 increase in yield compared to conventionally grown corn with no N applied. In 1999, interseeded legumes (except subterranean clover) in conjunction with the application of 56 kg N ha À1 and crimson clover interseeded without the addition of fertilizer N (with and without canopy reduction) resulted in grain N uptake levels equal to the 112 kg N ha À1 treatment.
