“…The promiscuously nodulating soybean contributes residual soil-N to maize following in rotation, in addition to providing the farmers with seeds and fodder for food and feed, and income from the marketing of these products (Vanlauwe et al 2001b;Sanginga et al 2002Sanginga et al , 2003. Some of the soybean varieties also have additional benefits of controlling nematodes and noxious parasitic weed (Striga hermonthica) in the production systems (Weber et al 1995a, b;Carsky et al 2000). Upland NERICA rice is grown in similar production systems to maize, but limited studies are available on integrating grain legumes such as promiscuously nodulating soybean into upland ricebased systems in the savannas.…”

Integrated soil fertility management (ISFM) involving a nitrogen-fixing grain legume, limited chemical fertilizer, and a resilient rice variety may reduce the rate of soil fertility loss and enhance rice productivity in fragile upland rice ecosystems. A 2-year, on-farm study was carried out at Eglimé in the southern Guinea savanna (SGS) and Ouake in the northern Guinea savanna (NGS) of the Republic of Benin to evaluate the contribution of dual-purpose soybean cultivars (Glycine max) to grain yield of upland NERICA Ò rice receiving low fertilizer N. In 2005, four dual-purpose, promiscuous soybean varieties (cv. TGX 1440-IE, TGX 1448-2E, TGX 1019-2EB, and TGX 1844-18E), a popular soybean variety (cv. Jupiter), and a popular rice (control) were sown in ten farmers' fields. In 2006, resilient upland interspecific rice (NERICA1) and popular rice (IRAT-136) were sown in all plots with only 15 kg N ha -1 . Soybean cv. TGX 1440-1E (late-maturing) ranked highest in nodulation, dry matter, shoot-and grain-N accumulation, and N-balance (21 kg ha -1 ) in NGS, while TGX 1448-2E (medium-maturing) surpassed other varieties in the SGS. Nitrogen fertilizer replacement value for growing cv. TGX 1440-1E in NGS prior to rice ranged from 17 to 45 kg N ha -1 depending on the reference rice. Grain yield of NERICA1 following 1-year rotation with soybean cv. TGX 1440-1E or TGX 1019-2EB was 1.5 Mg ha -1 greater than the yield obtained from farmers' control of 2-year continuous IRAT 136 rice cropping. Results indicate that integrating appropriate dual-purpose soybean in an ISFM package can enhance rice productivity in resource-limited smallholder production systems.

Further work involved testing the effect of a soybean crop as compared to sorghum as control on S. hermonthica parasitism in a subsequent maize crop and this study also assessed the effects of increasing soybean plant density and phosphorus fertilizer application on Striga reduction (Carsky et al, 2000). Application of phosphorus to soybean at higher soybean densities resulted in higher root length density, lower emerged S. hermonthica on maize and significantly higher maize yield (Carsky et al, 2000).…”

Application of phosphorus to soybean at higher soybean densities resulted in higher root length density, lower emerged S. hermonthica on maize and significantly higher maize yield (Carsky et al, 2000). These investigators reported that soybean rotation increased maize yield by 90% and suggested that the use of an efficacious soybean cultivar reduces Striga parasitism on a succeeding maize crop and that the effect is increased by application of phosphorus to the soybean.…”

“…However, it remains difficult to quantify to what extent changes in soil biota relate to variations in cereal yield. Legumes in cereal-based rotations can also reduce weed pressure; for example, that of the obnoxious weed Striga hermonthica (Carsky et al 2000;Franke et al 2006).…”

Legume-maize rotation and maize nitrogen (N)-response trials were carried out simultaneously from 1998 to 2004 in two distinct agro-ecological environments of West Africa: the humid derived savannah (Ibadan) and the drier northern Guinea savannah (Zaria). In the N-response trial, maize was grown annually receiving urea N at 0, 30, 60, 90 and 120 kg N ha -1. In Ibadan, maize production increased with N fertilization, but mean annual grain yield declined over the course of the trial. In Zaria, no response to N treatments was observed initially, and an increase in the phosphorus (P) and sulphur (S) fertilizer application rate was required to increase yield across treatments and obtain a response to N applications, stressing the importance of non-N fertilizers in the savannah. In the rotation trial, a 2-year natural fallowmaize rotation was compared with maize rotated with different legume types: green manure, forage, dualpurpose, and grain legumes. The cultivation of some legume types resulted in a greater annual maize production relative to the fallow-maize combination and corresponding treatments in the N-response trial, while there was no gain in maize yield with other legume types. Large differences in the residual effects from legumes and fallow were also observed between sites, indicting a need for site-specific land management recommendations. In Ibadan, cultivation of maize after the forage legume (Stylosanthes guianensis) achieved the highest yield. The natural fallow-maize rotation had improved soil characteristics (Bray-I P, exchangeable potassium, calcium and magnesium) at the end of the trial relative to legume-maize rotations, and natural fallow resulted in higher maize yields than the green manure legume (Pueraria phaseoloides). In Zaria, maize following dual-purpose soybean achieved the highest mean yield. At both sites, variation in aboveground N and P dynamics of the legume and fallow vegetation could only partly explain the different residual effects on maize.
