Salinity in irrigation water with organic fertilizer application on growth of castor bean

Plants grown under salt stress are adversely affected, however, it has been suggested the use of organic inputs in order to mitigate the deleterious effects of salinity. As a result, it aimed to evaluate the effect of different electrical conductivities of irrigation water due to the application of organic fertilizers in the cultivation of castor bean. The experiment was conducted in greenhouse located at...

Analysis of levels and determinants of technical efficiency of wheat producing farmers in Ethiopia

Wheat is one of the most important cereal crops in Ethiopia, ranking fourth in total cereals production (16%) next to maize, sorghum and teff. Despite its potential for wheat grain production, Ethiopia falls short of being self-sufficient in wheat, and is currently a net importer of wheat grain. This study examines levels of and determinants of technical efficiency of wheat producing farmers in Ethiopia. Data was...

Antimicrobial action against of Macrophomina phaseolina and control of the grey stem in soybean by homeopathic remedies Nosode and Sulphur

The aims of the study were to evaluate the control of botrytis in the soybean stem, spraying homeopathic solutions of Sulphur and Nosode of Macrophomina phaseolina in the dynamizations 6, 12, 24, 36 and 48CH. As additional treatment, we used distilled water and hydroalcoholic solution at 30% ethanol. In vitro tests were performed so as to analyze the number of micro-sclerotia and mycelial growth of the fungi, and in...

Effect of egg storage temperature and fumigation on hatchability of Cobb 500 and Hubbard broiler strains

Hatchability of Cobb 500 and Hubbard broiler strain eggs subjected to different levels of egg storage temperature and fumigation was studied at Debre Zeit Agricultural Research Center, Ethiopia. The different egg storage temperature levels employed were 10, 16 and 23°C and fumigation levels employed were fumigated and unfumigated. Fertility and hatchability were tested during the experimental period. Fertility is...

Field assessment of baits for frugivorous flies (Tephritidae and Lonchaeidae)

Hydrolyzed proteins are used as attractive agents in McPhail traps for monitoring of fruit flies (Tephritidae). There has been no defined role for monitoring of insects belonging to the Lonchaeidae family. Currently, there is a great concern in using most efficient and low-cost attractive materials. Thus, this study aimed at assessing the attractiveness of solid and liquid baits in capturing of frugivorous flies...

The efficiency of wheat yields by nitrogen dose and fractionation

The biomass productivity and wheat grains efficiency is determined by nitrogen dose adjustment (full or fractioned), environmental conditions, and cropping system. The aim of this study was to improve the efficiency of N-fertilizer usage on wheat to maximize the biomass productivity and grain yield by adjusting the full or fractioned nitrogen dose in favorable and unfavorable year conditions, in succession systems with...
