Curing in sweetpotato is a crucial pre- or postharvest practice that could guarantee improved shelf life,but rarely practised by sweetpotato farmers in Sub-Saharan Africa, principally due to lack of knowledge. Wound healing ability of cultivars has been associated with good root storability. In t...
Eight cassava (Manihot esculenta) cultivars were grown with or without mycorrhizal inoculation in flowing solution cultures containing approximately 0.1, 1, 10 or 100 ?M phosphate. Rice (Oryza sativa), maize (Zea mays), cowpea (Vigna unguiculata) and French bean (Phaseolus vulgaris) were included...
Field studies were conducted in 1991 and 1992 on a sandy loam soil in the derived savanna zone of south-western Nigeria to assess the effect of the underground organs of Imperata cylindrica (L.) Raeuschel on maize grain yield. Total dry matter of I. cylindrica in abandoned arable land averaged 16...
The effects of drought and plant density on fractional interception (f), radiation-use efficiency (RUE) and dry matter accumulation and partitioning to seeds in cowpea (Vigna unguiculata) need to be quantified in order to calibrate cowpea simulation models for West Africa. Accordingly, a short du...
To investigate the introduction of vetch/barley forage mixtures with a range of harvesting treatments in the winter season of Mediterranean-type environments, studies were carried out during 1994–97 at the National Agricultural Research Centre (NARC), Islamabad, which has an annual rainfall of ar...
