Leaf and seed yield of jute mallow (Corchorus olitorius L.) accessions under field conditions for two consecutive growing seasons
(Taylor & Francis Group, 2017-04-11)Jute mallow is a nutritious leafy vegetable used by many people in Africa. The purpose of this study was to select accessions with high leaf yield and seed yield. We investigated seven agronomic traits that are related ... -
Leguminous cover crops differentially affect maize yields in three contrasting soil types of Kakamega, Western Kenya
(Journal of Agriculture and Rural Development in the Tropics and Subtropics (JARTS), 2011)Maize production in smallholder farming systems in Kenya is largely limited by low soil fertility. As mineral fertilizer is expensive, green manuring using leguminous cover crops could be an alternative strategy for farmers ... -
Levels and distribution of progesterone in receiving waters and wastewaters of a growing urban area.
(Water Science & Technology, 2019-09-01)This study aimed at investigating the levels and distribution of progesterone in receiving waters and wastewaters in Arusha, a fast-growing urban area and the third largest city in Tanzania. Specifically, the study was ... -
Levels of community participation and satisfaction with decentralized wildlife management in Idodi-Pawaga Wildlife Management Area, Tanzania
(Taylor & Francis online, 2017-09-14)Participatory approaches to conservation are viewed as a plausible alternative to the old ‘fortress conservation’ approach. The design and implementation of these approaches in developing countries have tended to embrace ... -
Leveraging peer-to-peer farmer learning to facilitate better strategies in smallholder dairy husbandry
(SAGE journal, 2020-12-02)Peer-to-peer learning paradigm is seldom used in studying how farmers can increase yield. In this article, agent-based modelling has been applied to study the chances of dairy farmers increasing annual milk yield by learning ... -
