Effects of tillage practices, cropping systems and organic inputs on soil nutrient content in Machakos County

Low use efficiencies of inorganic fertilizers coupled with their rising costs has diverted attention of farmers towards organic sources. A study was conducted in Yatta sub-county between October 2012 to February 2013 short rains and April-August 2013 long rainy seasons to evaluate how tillage, cropping and organic inputs influenced soil nutrient status. A randomized complete block design with a split-split plot...

Chemical and biological managment of white mold (Sclerotinia sclerotiorum) disease in irrigated common beans (Phaseolus vulgaris) cultivation

The aim of this work was to study the effect of fungicides and biological agents on the control of white mold (Sclerotinia sclerotiorum) in common beans (cv. Pérola). Nine treatments were applied in six blocks (54 experimental units) using a randomized block design (RBD). The treatments were: T1 (control); T2, Bacillus subtilis strain QST 713 (4 L / ha); T3, B. subtilis strain QST 713 (4L / ha); T4, B. subtilis...

Impact of irrigation adoption on rural farmer’s welfare in Eastern Cape Province of South Africa: A propensity score matching approach

The aim of the present study was to assess the impact of irrigation adoption on farmer’s welfare measured by consumption expenditure and food consumption pattern. The paper was based on cross sectional farm household data collected in 2015 from a sample of 200 households in rural Eastern Cape of South Africa.  The study used a stratified random sampling method to select farming households from three district...

Correlation and path coefficient analysis in mid-altitude sesame (Sesamum indicum L.) germplasm collection of Ethiopia

The current investigation was aimed to study the genetic association of seed yield and its components in 81 mid-altitude sesame accessions based on morphological traits. The genotypes were evaluated in 9 × 9 simple lattice design at Melkassa Agricultural Research Center, Ethiopia, during the 2014 cropping season. The study mainly focused on determining the nature and extent of phenotypic and genotypic correlation...

OsHKT1;3 gene sequence polymorphisms and expression profile in rice (Oryza sativa L.)

Rice is sensitive to salt stress, but its sensitivity varies among genotypes, indicating natural variation in regulatory mechanisms and genetic makeup. High-affinity potassium transporters (HKTs) that transport cations across membranes play important roles in stress responses of plants. In this study, the gene sequence polymorphisms and expression level of OsHKT1;3 which is a member of the rice HKT gene family was...

Genetic diversity of rhizobia and plant growth promoting rhizobacteria of soil under the influence of Piliostigma reticulatum (DC.) Hochst and their impact on shrub growth

Piliostigma reticulatum shrub is a native legume found in fallow areas in dry and semi-dry savanna soil and is used in intercropping systems. The aim was to understand the functioning of the rhizosphere, particularly the involvement of symbiotic and free living-N fixing bacteria. Soil extracts collected from P. reticulatum roots were sampled in two contrasting areas and endophytic bacterial communities were isolated...
