Diversity of plant parasitic nematodes associated with common beans (Phaseolus vulgaris) in the Central Highlands of Kenya

Common beans (Phaseolus vulgaris L.) are the most important legume staple food in Kenya coming second to maize. In Central Highlands of Kenya, the 0.4-0.5ton ha-1 output is below the genetic yield potential of 1.5-2ton ha-1 partly due pests and diseases. Plant parasitic nematodes (PPN) have been reported to cause yield losses of up to […]

Potential of intercropping pesticidal plants with common bean in promoting natural enemies for pest management in agroecosystems

Use of pesticidal plants (PPs) is now evolving as one of the essential means to be used in protection of crop plants or produces from pest attack and substitute synthetic chemical pesticides. The PPs possess an array of properties such as toxicity, anti-feedance, repellency, deterrents and attractants and insect growth regulatory activities against important pests. […]

Effects of Rhizobium inoculation and cropping systems on micronutrients uptake and partitioning in common bean (Phaseolus vulgaris) and Lablab (Lablab purpureus)

The current study was conducted to assess the effects of Rhizobium inoculation and cropping systems on the availability and uptake of Cu, Zn, Fe and Mn in common bean (P. vulgaris) and lablab (L. purpureus). To achieve this aim, field experiments were conducted at Selian Agricultural Research Institute (SARI) for two cropping seasons in a […]

Influence of water stress and rhizobial inoculation on growth and yield of selected common bean cultivars (Phaseolus vulgaris L.)

Two season’s field experiment and single season screen house experiment were conducted to assess the effect of water stress periods and rhizobial inoculation in five P. vulgaris cultivars. The experiment consisted of two levels of rhizobia (with and without inoculation), two stress levels (with and without water stress) and five cultivars of P. vulgaris (KAT […]

Influence of water stress and Rhizobial inoculation on accumulation of flavonoids and anthocyanins in selected Common bean (Phaseolus vulgaris L.) cultivars

A two season field experiment and a single season screen house experiment were conducted to assess the effect of water stress periods and rhizobial inoculation in five (5) P. vulgaris (L.) cultivars. The experiment consisted of 2 levels of rhizobia (with and without rhizobial inoculation), two stress levels (with and without water stress) and five […]

Effects of Rhizobium inoculation and cropping systems involving common bean and lablab on water use efficiency, weeds and insects pests’ infestation

Field experiments were conducted during two cropping seasons (2015-2016) at Selian Agricultural Research Institute (SARI) farm to determine the effect of Rhizobium inoculation and intercropping systems of maize and legumes (common bean and lablab) on soil moisture content, weeds and insect pests’ infestation. The experimental design followed a randomized complete block design (RCBD) in a […]

Phenotypic characterization of common bean (Phaseolus vulgaris L.) accessions conserved at the Genetic Resources and Biotechnology Institute

The purpose of this study was to access variability in qualitative and quantitative traits among ten accessions that were obtained from Genetic Resources and Biotechnology Institute (GRBI) in Zimbabwe. The accessions were planted in a Randomized Complete Block Design, with three replicates. The qualitative and quantitative characteristics were recorded using the International Board for Plant […]

Role of Zn nutrition in membrane stability, leaf hydration status, and growth of common bean grown under soil moisture stress

Under controlled conditions four common bean genotypes (KS21486, D81083, Akhtar, and COS16) were exposed to drought by reducing soil moisture content from 100±5 % FC to 55±5 % FC, which supplied whether with 4.5 mg Zn kg-1 soil, or did not receive Zn. Superoxide dismutase activity; SOD, malodialdehyde content; MDA, membrane stability index; MSI, relative […]

Generation mean analysis to estimate genetic parameters for morphological traits in common bean (Phaseolus vulgaris L.)

Six generation (P1, P2, F1, F2, BC1 and BC2) derived from two crosses ((A.1007 × DER.) and (GOLI × D81)) of common bean were grown in a randomized complete block design with three replication in 2010 at research field of Razi University, Kermanshah, Iran. Experiment was executed to estimate different genetic effects of five morphological […]

Effect of straw mulch application on agronomic traits and grain yield of common bean (Phaseolus vulgaris L.) cultivars under drought stress

In order to investigate the agronomic traits and grain yield of common bean (Phaseolus vulgaris L.) cultivars under irrigation and straw mulch treatments, an experiment was conducted as factorial based on randomized complete block design with three replications at the research farm of the Faculty of agriculture, University of Tabriz, Iran in 2012. Treatments were […]
