“…Recently, the AfricaRice and partners extensively compared growth and yield performance of upland NERICA cultivars, especially NERICA 1, 2, and 4, with that of their O. sativa (WAB56‐104) and O. glaberrima (CG 14) parents (Ekeleme et al, 2009; Koné et al, 2009, 2010; Oikeh et al, 2009; Saito and Futakuchi, 2009; Kamara et al, 2010; Saito et al, 2010a, b, c; Sokei et al, 2010; Y. Sokei, unpublished data, 2010). These studies assessed cultivar differences in responsiveness to N and P fertilizer applications, weed competitiveness, and yield performance under different management practices (e.g., plant density, fallow system).…”

Rice yields have stagnated in West Africa at 1 to 2 Mg ha"^ because of unfavorable rice environments and poor management practices. Interspecific rice cultivars, the New Rice for Africa (NERICA), were developed by crossing Asian rice {Oryza sativa L.) and African rice (O. glaberrima Steud.) to improve upland and lowland rice productivity in resource-poor farmers' fields. This paper provides an overview of recent studies, performed by the Africa Rice Center and its partners, on evaluation of growth and yield performance of upland and lowland NERICA cultivars and modern Asian rice cultivars including the improved upland indica cultivars often termed aerobic rice. Upland NERICA cultivars were found to lack the expected combination of superior yield potential with weed suppressive ability (WSA) and adaptation to low soil fertility, instead sharing similarity in these characteristics with their O. sativa parent WAB56-104 but remaining inferior to their O. glaberrima parent CG 14 in terms of tillering ability and WSA. Some aerobic rice cultivars were identified for high yielding ability, strong WSA, and superior adaptation to low-fertility uplands and waterlimited lowlands. Some lowland NERICA cultivars outyielded improved lowland O. sativa checks and aerobic rice cultivars in favorable lowlands, whereas they did not perform well in water-limited lowlands. The implications of these findings for future challenges for genetic improvement in West Africa are discussed.

“…Such result could be explained by the positive effect of the cotton (as it is the only crop which benefit mineral fertilizer) on the soil due to the residual effect of certain nutrient especially P ( Van der Eijk, 2006). In fact, phosphorus may either stay in the soil and result in carry-over effects to the next crop or be lost by leaching or run off or fixed by oxide and hydroxide as usually occurring in the tropical acid soil (Koné et al, 2009 ;Koné et al, 2010b).…”

Four on-farm experiments in central Benin examined whether land-use succession and fertilizer treatments for prior cotton would sustain subsequent maize crop yields and achieve balanced plant nutrition. Treatments consisted of three prior land use successions, i.e. before planting maize (egusi melon-cotton-cottonmaize, cotton-maize-cotton-maize and cassava-maize-cotton-maize) including for each, four replications of three fertilizer treatments: recommended practice [150 kg ha -1 of 14-23-14 (NPK) plus 5S-1B, applied 25 days after sowing and 50 kg ha -1 of urea on 40 days after sowing], NPK-SB mixed with urea (the recommended amount of NPK-SB and urea are mixed then applied 40 days after sowing) and reduced NPK-SB dose (recommended practice, but the amount of NPK-SB is reduced to 100 kg ha -1 ). Prior cotton and subsequent maize yields and nutrient uptake were not significantly affected by fertilizer treatments. Furthermore, fertilizer treatments had no significant effect on soil chemical properties before planting the subsequent maize crop. Land use types had significant effect on cotton yields, soil chemical properties, subsequent maize yields and nutrient uptake. The lowest yield and nutrient uptake were registered in the cotton-maize-cotton-maize land use succession and the highest in the egusi melon-cotton-cotton-maize succession. For sustainable soil fertility management, adoption of adequate crop succession system and recommended fertilizer application practice are suggested.

“…Thus we conclude that the incorporation of cowpea or native grass residues can prevent from P content depletion in acid soil. The effect native grass of P as observed in actual study is an essential finding that can help in management of agricultural land in tropical zone where P-deficient in acid soil in among the major limiting factors [18].…”

Abstract-Tropical soils have low fertility and chemical fertilizers are not affordable for most of the farmers, especially in West Africa. The development of low cost technologies for amending agricultural soils in this environment is needed. Biological and organic fertilizers were tested in 20 farmers' fields in central Benin for rainfed rice production on acidic plinthosol under monomodal rainfall pattern conditions. Short time matured cowpea and native grass fallow were preceding NERICA1 and Ina Okpè rice cultivars that are interspecific (Oryza glaberrima × Oryza sativa) and local varieties respectively. Cowpea and bush residues were incorporated into soil before rice seeding. Soil nutrients (C,N,K, Ca and Zn) contents were significantly depleted whereas null balance was observed for soil available-P content. An increased of soil content in Fe (>130 mg kg -1 ) was significantly observed in all the treatments. Highest yield of 1.6 t ha -1 was recorded in the treatment composed of cowpea and NERICA1. The study technology was deemed suitable in deficient-P acid soil whereas the land foot slope position was excluded to avoid potential increasing of Fe content (iron toxicity of rice) in soil of the subsequent lowland. Minimum chemical fertilizer was required for improving rainfed rice cultivation on plinthosol in monomodal rainfall pattern ecology.
