The Maize streak virus (MSV) disease has been one of the most devastating diseases of maize (Zea mays L.) in all the countries of West and Central Africa (WCA). For a long time, breeding for resistance to the disease was frustrating because of lack of facilities for uniform artifi cial inoculatio...
Collecting missions under the auspices of the IITA to Zimbabwe, Tanzania, Chad, Swaziland, Lesotho and Somalia covered over 24 000 km and collected 2023 accessions of cultivated crops and wild material. Details are given for each of the 6 missions, with information on routes taken, regions visite...
Stem borers are one of the major constraints limiting maize productivity in Africa. The most important species reducing maize yield in West and Central Africa are Sesamia calamistis, Eldana saccharina and Busseola fusca. Both the pink stem borer (Sesamia calamistis Walker (Pyralidae) and the sug...
Soil water management is critical for sustainable crop production, particularly in drought-prone environments. A range of strategies can be used to address spatial (need to improve in-situ infiltration) and temporal (need to improve water holding capacity /storage) to increase soil water availabi...
Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affe...
On a Ferralic-haplic Acrisol (terre de barre non degradee) in Southern Benin Republic, four years after the establishment of the hedgerows, yields of maize and cassava alley cropped with Leucaena leucocephala and Cajanus cajan were no better than those in control plots without hedgerows. Reduced ...
Tillage practices contribute greatly to the labour cost in modern intensive agriculture in any crop production system resulting in lower economic returns, especially in developing countries where there is most concern for sustainable production without degradation of the natural resource base (Ja...
Crop residue use for soil mulch and animal feed are the two major competing purposes and the basic source of fundamental challenge in conservation agriculture (CA) where residue retention on farm plots is one of the three CA principles. Using survey data from Kenya and applying bivariate ordered ...
