In order to investigate the effect of micronutrients foliar application on seed yield and essential oil of black cumin, a field experiment was conducted based on Randomized Complete Block Design (RCBD) with three replications at the farmlocated in Naqadeh city, West Azerbaijan province, Iran, during 2015-2016 growing season. Treatments were separate application of Nano-Iron, Nano-Zinc and Nano-...

introduction: the need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. on the basis of environmental and economic considerations, these materials require treatment and management. anaerobic digestion and creation of biogas are the most effective methods of waste management. several parameters affect the anaerobic digestion of ...

in order to evaluate nitrogen fixation ability and nutrients uptake in three cultivars of common bean (phaseolus vulgaris l.) inoculating with some types of inoculants containing different strains of rhizobium leguminosarum; bv. phaseoli an experimental design was conducted in khoramdarah region in 2006 and 2007. in this investigation three types of biological fertilizers including rb117, rb123...

sclerotinia stem rot (ssr), caused by sclerotinia sclerotiorum, is the most important diseases of canola (brassica napus) in iran. in order to study of the impact of ssr on canola yield, infection situation and yield of 80 fields in four different regions of golestan province (gorgan, ali abad, kalaleh and gonbad) in north of iran, was recorded during two growing seasons (2006 and 2007). ssr se...

xanthomonas campestris pv.musacrearum causes banana wilt disease (bxw disease) which occurs at different epidemic phases in east and central africa (eca). in the endemic areas, there are many banana fields with over 80% bxw disease incidence. this study aimed at rehabilitating banana fields heavily infected with bxw disease in uganda, kenya and dr. congo. farmer managed trials were established ...

the objective of the present work is to analyse the potential of using non-classical additions in concrete and mortar compositions such as coal bottom ash (ba) and biomass ash (bio), as partial replacing binder of ordinary portland cement. it is intended to deal with production of these type of wastes and its accumulation and contribute to the minimisation of carbon and embodied energy in const...

This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...
