(Pergamon, 2008-07-01)This paper assessed the relative economic efficiency and output supply and input demand responses of women farmers in western Kenya. The results showed that women are as technically and allocatively efficient as men. ... -
Integrated management of Striga hermonthica, stemborers, and declining soil fertility in western Kenya
(Elsevier, 2008-05-10)Striga hermonthica (Delile) Benth., stemborers, and declining soil fertility are serious threats to sustainable food production in the Lake Victoria zone of Kenya. To address these constraints, promising integrated crop ... -
Amplification of 1-amino-cyclopropane-1-carboxylic (ACC) deaminase from plant growth promoting rhizobacteria in Striga-infested soil
(Academic Journals (Kenya), 2003)Experiments were conducted in pots to determine the growth effect of different rhizobacteria on maize under Striga hermonthica infestation. Three bacteria were selected based on their plant growth promoting effects. Whole ... -
Smallholder market participation under transactions costs: Maize supply and fertilizer demand in Kenya
(Pergamon, 2008-08-08)This paper assessed the effects of transactions costs—relative to price and non-price factors—on smallholder marketed surplus and input use in Kenya. A selectivity model was used that accounts for the effects of transactions ... -
Livelihood strategies of resource-poor farmers in Striga-infested areas of western Kenya
(2008-11)Striga hermonthica (del) Benth is threatening rural livelihoods in western Kenya where maize is the major food and cash crop. Vulnerability analysis was conducted on a sample of 802 households in eight districts of ... -
Increasing imazapyr-resistant maize yield by increasing plant density under natural Striga hermonthica infestation
(ScienceHuß, 2010)Maize (Zea mays L.) is one of the most important crops in East Africa serving both as a staple food and cash crop to millions of people. As a vegetable, it is produced as green maize cobs, sweet corn or baby corn. Yields ... -
