“…The use of heavy machinery can induce compaction on the field which could have a consequential effect on the amount of soil that can adhere to the root of groundnut during harvesting. The nonsignificance of soil loss due to groundnut harvesting was similar to the findings of Dada et al (2016) who reported no significant difference in soil loss due to yam harvesting from two locations (FUNAAB and Alabata) in Nigeria. This result also corroborated Lindemans (2002) who identified a reduction in soil loss through compaction but stated that this relationship has an elastic limit.…”

“…Nowadays in Nigeria, research efforts in curbing water erosion increase (Babalola et al 2007;Babalola 2007;Oshunsanya et al 2010;Oku et al 2016;Ewetola 2017) among several others. Most of these efforts focused on water and tillage soil erosion, whereas the significant amounts of soil that is lost from arable land during harvesting of root, tuber, and bulb crops are receiving low attention (Oshunsanya 2016;Dada et al 2016Oshunsanya et al 2018.…”

The research was conducted to study the growth and the yield of the groundnut plant and to quantify the soil loss after groundnut harvesting as influenced by induced soil compaction. A ten kilogram of soil was packed in the pots with an initial bulk density of 1.05 Mg m-3, then it were compressed to1.57, 1.72, 1.88, 2.04, and 2.42 Mg m-3. The research was conducted in a completely randomized design with three replications. Groundnut seeds were sown in pots and the plant growth data were collected in a 2-week interval while force and energy of harvesting and soil loss due to groundnut harvesting were determined at 12 weeks after sowing. Data were analyzed using ANOVA and Fishers LSD at P= 0.05. Soil compacted to1.88 Mgm-3 produced more taller plant, more higher number of leaves and branches than control. Soil compaction significantly reduced the number of pods, roots, and fresh root weight compared to control. Bulk density (2.04 Mgm-3) required a significantly higher force (42.47 N) and energy (45.73 J) in harvesting than control and other compaction levels. Soil loss due to the groundnut harvesting increased (13- 42%) in all compaction levels although statistically not different. Soil compaction beyond 1.88 Mg m-3 could affect the growth and the yield of groundnut and could increase the soil loss at harvesting.

“…In Sub-Saharan Africa with Nigeria inclusive, effort have been made to reduce soil erosion, particularly water and wind erosion. However, considerable soil masses are exported from cropped land during harvesting of root, tuber, bulb and some legume crops such as yam, cassava, onion and groundnut (Dada et al, 2016;Isabirye et al, 2007;Mwango et al, 2015). Soil and associated nutrients sticking to harvested crop that is removed from the field is referred to as soil loss due to crop harvesting (Poesen et al, 2018;Ruysschaert et al, 2004.).…”

Soil loss due to crop harvesting is a recognized erosion process which has significantly contributed to soil degradation. Despite its significance, soil loss due to crop harvesting has been given little attention in Benue state and Nigeria at large. This is evident in the paucity of information on soil loss due to crop harvesting in Nigeria. Therefore a field experiment was conducted to quantify soil and nutrient loss due to yam harvesting in two local government areas (Kwande and Ushongo) of Benue state and to identify factors which could contribute to soil loss in these areas. Data collected on soil loss were subjected to t-test at α = 0.05. Average crop yield in Kwande was 18.9 t ha-1 and 16.3 t ha-1 in Ushongo with corresponding soil loss of 3.26 t ha-1 harvest-1 and 1.97 t ha-1 harvest-1 respectively. Higher soil loss observed in Kwande compared to Ushongo can be attributed to higher crop yield and clay content of the soil. Crop yield, clay content and soil organic matter correlated positively with soil loss in Kwande (r = 0.75, r = 0.58, r = 0.65) while in addition to crop yield and clay content sand correlated negatively with soil loss in Ushongo (r = 0.77, r = 0.60, r = -0.60). Soil nutrient losses for nitrogen, phosphorus and potassium were significantly higher in Kwande compared to Ushongo by 2.71, 2.67 and 2.02 times respectively. The findings suggest that soil loss in these areas could degrade the land within a short time, especially where mono-cropping of yam is practiced. Farmers are therefore advised to hand-rub yam tubers while harvesting on the field and practice crop rotation.

“…La production mondiale d'igname a presque triplé au cours des trois dernières décennies, en particulier au Nigeria, au Bénin et au Ghana ; le potentiel de l'igname laisse à penser qu'elle pourrait être, dans un proche avenir, un recours pour répondre aux besoins alimentaires grandissants des populations (Asiedu et Sartie, 2010). En Afrique, bien que la zone de production d'igname se concentre dans les pays côtiers du Golfe de Guinée (Vernier et Dansi, 2006 ;Olufemi et al, 2016), sa culture s'étend ces dernières décennies vers les zones tropicales humides d'Afrique centrale (Cameroun, République Centre-africaine, Tchad, Gabon) ainsi qu'à Madagascar. Le Brésil, la Colombie, la Jamaïque, Haïti, la Dominique, la Papouasie-Nouvelle Guinée et Sao-Tomé sont aussi des pays producteurs d'igname (FAOSTAT, 2019).…”

Cette revue de littérature couvre la botanique, la domestication, l'écologie, les systèmes de culture, la transformation ainsi que les contraintes et perspectives pour une production durable des ignames en Afrique tropicale. L'igname est un taxon d'espèces essentiellement tropicales qui nécessitent des températures élevées. Ainsi, la germination est optimale entre 25 et 30°C, alors que des températures inférieures à 15°C ou supérieures à 35°C la retardent. La culture de l'igname se pratique avec succès dans des zones où la pluviométrie varie entre 1000 et 1800 mm ; toutefois, il est possible de cultiver l'igname avec une pluviométrie de 600 mm mais le rendement reste faible. L'igname, pour la croissance végétative et une bonne tubérisation, préfère des sols limono-sableux ou sablo limoneux, ayant une conductivité hydraulique de 15 cm/h, une densité apparente comprise entre 1,1 et 1,6 g.cm À3 et surtout légers, profonds (> 0,6 m), bien drainés, riches en matière organique, en azote, en potasse, en magnésium et en calcium ; un pH compris entre 5 et 7 est aussi propice à une bonne culture d'igname. Au-delà des paramètres édaphiques et des facteurs climatiques, les pratiques culturales, notamment le type de cultivar, la densité de plantation, la date de plantation, les adventices, les maladies et ravageurs, sans occulter l'histoire des parcelles et les pratiques paysannes de gestion du sol, ont un effet sur la productivité des ignames. Les facteurs déterminant le choix des variétés d'igname cultivées par les producteurs sont principalement : la qualité culinaire des tubercules, la productivité, la valeur commerciale, la facilité de multiplication, la qualité des cossettes, la précocité de tubérisation, la conservation, la facilité de culture, le rôle dans l'alimentation et l'importance pour les cérémonies rituelles. Mots clés : sécurité alimentaire / tubercules / déforestation / consommation / BéninAbstract -Yam: ecology, cropping systems and food uses in tropical Africa. A literature review. This paper presents a literature review about botany, ecology, cropping systems, processing, constraints and prospects of sustainable yam production in tropical regions of Africa. Yam is a taxon of mainly tropical species requiring high temperatures. Germination is optimal between 25 and 30°C, whereas temperatures below 15°C or above 35°C delay it. Yam is successfully cultivated in areas with rainfall ranging from 1000 to 1800 mm; however, it is possible to cultivate yam with a rainfall of only 600 mm, but yield remains low. To reach vegetative growth and good tuber formation, yam prefers sandy-loamy or loamy soils, with hydraulic conductivity of 15 cm/h, apparent soil density between 1.1 and 1.6 g.cm À3 and light and deep soils (> 0.6 m), well drained, rich in organic matter, nitrogen, potash, magnesium and calcium. A soil pH from 5 to 7 is suitable for a good yam production. Beyond the edaphic and climatic factors, cultivation practices, including cultivar, plantation density, date of planting, management of weeds, diseases an...
