Preliminary studies on termite damage on rural houses in the Central Rift Valley of Ethiopia
Termites are serious pests of agricultural crops and rural houses in Ethiopia. Some attempts were made to control termites on crops. However, termite problem on rural houses is a neglected area regardless of the intensity of the problem which at times results in total collapses of newly constructed houses. To collect preliminary information on status of termite infestation to rural houses, surveys were conducted in...

Major pearl millet diseases and their effects on-farm grain yield in Uganda
Pearl millet (Pennisetum glaucum) is an important food and cash crop for many people living in the semi arid areas of Uganda. But information about the common diseases and their effect on yield is lacking yet it is important in designing a realistic and focused pearl millet breeding programme aimed at increasing yield. A disease survey was done in 2012 in the farmers’ fields in the predominantly pearl millet...

Morphophysiological characteristics of maize inoculated with Azospirillum brasilense and Herbaspirillum seropedicae as seed treatment, cultivated in different types of soil
This work aimed to evaluate the morphological characteristics of maize inoculated with Azospirillum brasilense (AbV5) and Herbaspirillum seropedicae (SmR1) by seeds treatment, grown in four different types of soil from the Western region of Paraná. The experiment was conducted in a greenhouse at State University of Western Paraná. The used experimental design was a randomized block, in factorial scheme...

Study on diversity of Phaseolus spp. landraces with reference to global climate change
The purpose of this study was to investigate the differences between Phaseolus vulgaris landraces and to determine their adaptation to local climatic conditions to enrich the genetic diversity of the collection of the Institute of Plant Genetic Resources (IPGR), Sadovo with original plant material better adapted to current climatic changes. The study was performed in four different geographical regions of Bulgaria...

Impacts of wetland cultivation on plant diversity and soil fertility in South-Bench District, Southwest Ethiopia
Wetlands provide enormous socioeconomic and environmental values. However, wetlands are threatened by conversion for agricultural land in southwestern Ethiopia. The study aims to assess the impact of wetland cultivation on plant species richness, composition and soil fertility. Plant species richness and composition was investigated for 30 plots in each site of adjacent uncultivated and cultivated wetlands sites and...

Assessment of on-farm diversity of wheat varieties and landraces: Evidence from farmer’s fields in Ethiopia
Analysis of spatial diversity, temporal diversity and coefficient of parentage (COP) were carried out along with measurements of agronomic and morphological traits to explain on-farm diversity of modern varieties or landraces of wheat (Triticum aestivum L. and Triticum durum L.) grown by farmers in Ethiopia. Farm level surveys showed low spatial diversity of wheat where only a few dominant varieties appeared to occupy a...

The effect of harvest conditions and drying temperature on drying kinetics of two popcorn genotypes
The present work aimed to assess the effect of the initial moisture content of grains (at harvest), velocity of the harvester cylinder and air temperature on the diffusion coefficient, as well as to achieve the activation energy of the drying process of two popcorn cultivars. Grains of popcorn from the cultivars Zélia and CMS 43 were mechanically and manually harvested and thrashed. The rotations of the threshing...
