“…et al, 2004). However, similar grain yields of maize were reported (Ennin et al, 2004) when maize followed the medium maturing cowpea variety "Soronko'' and mucuna. Maize yields following soybean at both locations were similar to maize yield in continuous maize cropping system.…”

“…There have been several studies on Mucuna (Mucuna pruriens var. utilis) cover crop in West Africa in recent times (Boateng, 1998;Osei Bonsu et al, 1998;Carsky et al, 2001b;Ennin et al, 2004). The primary benefit derived from mucuna in cropping systems, which has resulted in its adoption across agroecologies in West Africa and in Latin America is its weed suppression ability especially of noxious weeds such as Rottboellia, Imperata cylindrica, and Chromolaena odorata (Carsky et al, 2001).…”

“…The LGU recommendations for peanut (Arachis hypogaea) N credits ranged from 22 to 50 kg N ha -1 , but we did not find any North American studies that reported a peanut N credit. However, Ennin et al (2004) determined the peanut N credit to corn to be 0 for their site conditions in Ghana, Figure 2. Box plots showing the reported legume N credits recommended by U.S. land grant university cooperative extension services (green, right) and determined empirically by peer-reviewed studies (yellow, left).…”

HighlightsAdjusting nitrogen (N) fertilization rates for corn following legumes can reduce N losses.Including perennial legumes in corn rotations can reduce nitrate-N losses and improve water quality.Crop rotations that include three or more years of legumes can be cost-effective.Corn-soybean was the most cost-effective, with a net benefit in nitrate-N loss reduction compared to continuous corn.Abstract. Legumes included in corn-based crop rotation systems provide a variety of benefits to the subsequent crops and potentially to the environment. This review aims to synthesize available data from the literature on legume N credits and the effects of crop rotations on water quality, as well as to analyze the cost benefits associated with different legume-corn rotation systems. We found that there was much variation in reported values for legume N credits to subsequent corn crops, from both empirical results and recommendations made by U.S. land grant universities. But despite inherent complexity, accounting for this contribution is critical when estimating optimal N fertilizer application rates as part of nutrient management. Results from research on the influence of crop rotations on water quality show that including legumes in corn-based rotation systems generally decreases nitrate-N concentrations in subsurface drainage discharge. Our cost analysis showed that incorporating legumes in cropping systems reduced N fertilizer and pesticide costs compared to conventional cropping systems, i.e., continuous corn and corn-soybean rotations, but extended rotations, such as corn-soybean-alfalfa-alfalfa-alfalfa, are not as profitable as conventional systems in the U.S. Midwest. In comparing continuous corn and corn-soybean rotations, although their impacts on water quality are not significantly different when using overall means from the literature data, corn-soybean rotations are more profitable than continuous corn. When using data from papers that directly compared the two, we found that switching from continuous corn to corn-soybean can provide a benefit of $5 per kg N loss reduction. The cost analysis methods used could be tailored to any location or management scenario with appropriate inputs and serve as a useful tool for assessing cost benefits for other agricultural conservation practices. Legume-corn crop rotations have the potential to be an effective conservation practice with the ultimate goal of improving water quality, and, with further research, these rotations could be made even more effective by integrating them into a multi-practice system. Keywords: Conservation practice, Cost analysis, Crop rotation, Nitrate, Nutrient management, Water quality.

“…A few studies have assessed N 2 fixation and N contribution by groundnut to cropping systems in Ghana (Dakora et al 1987 ; Ennin et al 2004 ; Konlan et al 2013 ). Only a limited number of genotypes were tested using the N balance and/or N difference techniques.…”

About 70% of the groundnut (Arachis hypogaea L.) produced in Ghana is from the Guinea savanna. However, low soil nutrients, especially N, together with erratic rainfall distribution have often resulted in poor grain yield. The aim of this study was to evaluate plant growth, N2-fixing efficiency, N contribution, water-use efficiency and pod yield of 21 elite groundnut genotypes in the Guinea savanna of Ghana, using the 15N natural abundance technique. The data revealed significant variations in plant growth, symbiotic N contribution, and pod yield among the 21 genotypes tested at each field site. Average N contribution by groundnut genotypes ranged from 48 to 108 kg N ha−1. Also, mean pod yield ranged from 0.58 to 2.1 t ha−1. Genotypes ICGV-IS 08837, ICG 6222, ICGV 03315 and NKATIESARI demonstrated superior plant growth, symbiotic N contribution and greater pod yield. In fact, ICGV-IS 08837 yielded almost 2.5 fold more than CHINESE which is the most widely cultivated variety in the region. Genotypes ICGV-IS 08837, ICG 6222, ICGV 03315 and ICGV 99247 are therefore recommended for development into varieties for the Guinea savanna of Ghana. Genotypes ICG (FDRS) 4, ICGV00362 and ICGV99247 exhibited increased water-use efficiency, but were low in N2 fixation and N contribution, and would therefore be good parental material in breeding programs aimed at enhancing water-use efficiency in high N2-fixing genotypes.
