Plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. In this study, field experiment carried out as factorial Randomized Completely Block Design (RCBD) in 3 replications. Different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. Second factor was different plant spaces (10, 15, 20 and 25 cm). Results showed th...

The experiments were carried out at the Regional Agricultural Research Station, Rahmatpur, Barisal during the rabi seasons of 2001-2002 and 2002-2003 to study the impact of different sulphur levels on bulb yield, storability and economic return of onion. Sulphur application had significant effect on yield components and bulb yield of onion. The highest bulb yields (19.75 and 19.88 t/ha) were ob...

in this research seed of twelve population of iranian onion were gathered from different part of country (horand ahar, germez rey, goligesa zanjan, germez azarshahr, sefid kashan, zard neishabur, sefid gom, dorche esfahan, sefid neishabur, germez neishabur, sefid fathabad, es hag abad neishabur). the experiment was factorial based on a randomized complete block design (rcbd) was conducted in ag...

production of onion all thruough the year particularly in semi tropical regions has been considered as an alternative to fulfil the local markets needs. in order to determine the best amount and method of urea fertilizer application so that to have higher yeild and lower amount of nitrate content the effects of seven levels of urea fertilizer including 0, 90, 180, 270, 360, 450 and 540 kg of ni...

Onion (Allium cepa L.) is a spice crop and valuable economic cultivated in variety of environments around the world. Because its export demand, it extremely important terms foreign exchange. Drought stress, waterlogging heat cold salinity stress all have an impact on onion growth, production, yield different ways. A lack water causes low productivity, therefore to increase yield, constant suppl...

abstract an experiment was conducted to study growth analysis and evaluation of change in simple non- structural carbohydrates (sucrose, glucose and fructose) during bulb formation of ghermez azarshahr , zargan, safid naishaboor and safid qom cultivars in randomized complete block design containing three replications. seeds were sown in nursery in early february and seedlings were transplanted ...

Increasing onion yield and improving bulb quality are essential aims for growers to fulfill the requirements of the market and the consumers. Two field experiments were carried out during two successive seasons; 2011/2012 and 2012/2013 at the experimental station of National Research Centre, Beheira Governorate (North of Egypt) to find out the influence of some bio-stimulants i.e., yeast extrac...
