Evaluation of phenolic content of common bean (Phaseolus vulgaris L.) in association to bean fly (Ophiomyia spp.) infestation

Common bean is the most important pulse crop in Kenya, though small scale farmers have limited access to pest resistant seeds. This has therefore made common bean yields remain below 1000kgha-1, while the potential is 2000kgha-1. However phenolics are secondary metabolites present in plants and this could be an attribute contributing to common beans resistance […]

Analysis of mungbean germplasm against mungbean yellow mosaic virus disease and its management

The present experiment was planned to manage yellow mosaic disease through resistant source, application of nutrients and indirectly by insecticides against whitefly. Ten genotypes (MPP 16082, MPP 16001, MPP 16024, MPP 16016, MPP 16075, MPP 16074, MPP 16005, MPP 16055, MPP 16015 and MPP 16073) were sown in augmented design to find out resistant source. […]

Growing Bush bean (Phaseolus vulgaris L.) and Kangkong (Ipomea aquatica) using natural pesticides and organic fertilizers

Two experiments were conducted to evaluate the use of natural pesticides to control pests in bush bean (Phaseolus vulgaris L.) and to study the effect of different organic fertilizers on growth and yield of Kangkong (Ipomea aquatica). In the first experiment Neem Seed Kernel Extract (T1), Tobacco Décoction (T2), Cow Urine (T3), and Synthetic Insecticides […]

Abundance of predators in country bean field during summer season

The study was conducted at the experimental field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during March to June 2009 in order to know the abundance of biological control agents (predators) in country bean ecosystem. During the study period the predators, black ant (Formicidae), lady bird beetle (Coccinellidae), Stink bug (Pentatomidae), Damsel fly […]
