Integrated management of pigeon pea pests improves yields in Kenya

Résumé fourni par la source

This study was conducted in lower eastern Kenya to compare the impact of various management practices on pigeon pea pests. Six and eight farms planted with pigeon pea crops were used in seasons one and two, respectively, based on Agro-Ecological Zones (UM & LM). In each farm, three plots were established where pests were managed using integrated pest management (IPM), farmer practice (FP), or control without pest management, as a check. Results showed a highly significant difference (p<.001) in the pigeon pea grain yields with 1.66±0.041; 0.91±0.042 tons per Ha for UM and LM Agro-ecological zones, respectively. An increase of 43.29% and 52.35% in the number of pods was recorded in IPM and FP-managed plots, respectively, compared with the control. Furthermore, pod weight (g) for the IPM plot increased by 39.24%, while in the FP-managed plots, it increased by 48.22%. Additionally, grain weight (g) increased by 34.77% in the IPM and by 51.60% in the FP-managed plots. A significant (p=0.05) increase in percent protein content was recorded, with 16.85%, 16.67%, and 14.64% from FP, IPM, and control-managed plots, respectively. Pest management is a key input in pigeon pea production, and farmers need to manage pests for improved yields.
