(1) Background: the production of onion seeds is limited by competition between and vegetative organs scape lodging. However, information on effects plant growth regulation seed scarce. Aim present study was to evaluate yield components germination ability as affected timing dose an ethylene application, a regulator able modulate shoot–flower competition; chitosan, elicitor defense mechanisms i...

Aerosol filter samples were collected at a highelevation mountain observatory (4180 m a.s.l.) in the northeastern part of the Qinghai–Xizang (Tibet) Plateau (QXP) during summer 2012 using a low-volume sampler and a micro-orifice uniform deposit impactor (MOUDI). These samples were analyzed for water-soluble inorganic ions (WSIs), organic carbon (OC), elemental carbon (EC), watersoluble organic ...

Onion bulb crop production using sets as planting material has been increasing for the last decade in response to high demand and because of their yielding capacity adaptability continuously changing growing environment. The objective this experiment, therefore, was investigate effect seed rate on yield quality onion setsas a highly demanded material. Treatments comprised two cultivars (Kamlin ...

Relying on Power Holding Company of Nigeria (PHCN) for power distribution in University Port Harcourt (Uniport) has not really helped satisfying the overall requirements, considering fact that alternative renewable sources exist its environs and tapping into it will help ameliorate these challenges. This work involves proposing utilization photovoltaic (PV) source using Uniport as a case study....

Submit Manuscript | http://medcraveonline.com ecological zones of Pakistan includes Phulkara, Swat-1, Sariab Red, Chiltan-89, Desi Red and Nasarpuri. There always remains need to widen the genetic diversity in onion. Therefore germplasm (five entries) received from Asian Vegetable Research and Development Centre (AVRDC), Taiwan, was primarily evaluated during 2005-06 and 2006-07 along with six ...

thrips tabaci is one of the most important pests causing serioues damages on onion s in iran despite several chemical sprayings. to assess the population density and damage of the thips on onion, improved sefid-e-khomein genotype along with seven other iranian cultivars of onoin were planted in a rcb design with four replications in two separate experiments (sprayed and non-spray ed ) in arak f...
