Influence of six years of no-tillage and conventional plowing on fertilizer response of maize (Zea mays L.) on an alfisol in the tropics por Lal, R.

“…The effects of four rates of N (0, 40, 80, and 120 kg/ha) and three rates of P (0, 13, and 26 kg/ha) on maize (Zea mays L.) response were investigated for no‐tillage and conventionally plowed plots on an Alfisol in southwestern Nigeria. These, experiments were conducted for three consecutive seasons. …”

Nitrogen contribution by leucaena (Leucaena leucocephala) prunings to maize in an alley cropping system por Mulongoy, K., van der Meersch, M.

“…The N uptake of maize was assessed on an Alfisol in a sole crop and in an alley cropping system in southwestern Nigeria. Although the application of prunings increased the maize N content in both sole and alley-cropped maize, the N contributed to the maize by the prunings was low, ranging between 4.4 and 23.8 kg ha−1. …”

Dynamics of the population sizes of cowpea and soybean rhizobia at three locations in West Africa por Mulongoy, K., Ayanaba, A.

“…Maradi, in Niger, is subject to temperature extremes and prolonged drought; the soil contained fewer rhizobia than those at Onne and at the International Institute of Tropical Agriculture both of which are located in the humid zone of Nigeria. Numbers of rhizobia, especially of cowpea rhizobia in the top 15 cm six weeks after planting, were significantly higher in fields cropped to cowpeas than fallow soil, indicating that cowpea crops built up the population of compatible rhizobia in the root zone.Bradyrhizobium japonicum specific for American soybean cultivars had the smallest population at all three locations, confirming the need for inoculating these cultivars with appropriate rhizobia in tropical soils. …”

Physical properties of earthworm casts and surface soil as influenced by management por Lal, R., Akinremi, O.O.

“…We compared physical properties of worm casts with the properties of the surface 0 to 5 and 5 to 10 centimeters of soil under different management systems for an Alfisol in southwestern Nigeria. Soil management treatments consisted of comparison of notillage with conventional plowing and harrowing, surface application of residue mulch with no mulch, and application of recommended rate of chemical fertilizer with no fertilizer application. …”

Evaluation of sampling methods for megalurothrips sjostedti (trybom) (thysanoptera: thripidae) on cowpea por Salifu, A.B., Singh, S.R.

“…Five sampling methods were evaluated for efficiency in estimating field populations of Megalurothrips sjostedti (Trybom) on cowpeas in Nigeria. The methods (sticky traps, water traps, sweep netting, shaking plants and the collection of whole plant samples) were judged on the basis of low sample variance, low cost and fidelity to absolute population trends. …”

Selected experiences with irrigation management transfer: Economic implications por Johnson, S.H.

“…This paper explores this transfer process in Indonesia, Colombia, New Zealand and Nigeria. From this sample it can be hypothesized that in countries where governments have had the political will to increase water fees to close to the real O&M cost, the process of irrigation management transfer has been smoother. …”
