Effect of Cropping System and Variety on the Incidence and Severity of Black Bean Aphid in Western Kenya
- D. W. Wosula; M. Ndong’a; J. Ogecha
- Beans (Phaseolus vulgaris, L) are among the most important food legume crop in Kenya. However, damage by black bean aphid (Aphis fabae, Scopoli) has greatly reduced bean yields. This study was undertaken with a general objective of determining A. fabae incidence and severity on common bean varieties under different cropping systems in western Kenya. Plots were planted with three bean varieties (KK8, GLP X92 and GLP 1127) in pure stand and intercropped with maize (WH505) on Masinde Muliro University of Science and Technology farm during the short and long rain seasons of 2013 and 2014 respectively. Randomized complete block design in four replications was used. Twenty plants per plot were randomly selected and sampled for data collection on incidence and severity. Analysis of variance was used to compare means of aphid incidence and severity in pure stand and intercropped bean plots; means of leaf width, plant height, number of pods and number of seeds per pod for common bean varieties and means of grain yield among varieties. LSD was used to separate means at P
