Seed cotton yield and fiber qualities may be significantly altered by a number of agronomic practices. The present study investigates the effect of nitrogen levels on cotton cultivar's seed cotton yield and fiber quality traits. Three cotton cultivars (NIAB-111, CIM496 and FH901) were tested against four nitrogen levels (0, 60, 120 and 180 kg ha) to check reliability, the highest yielding and g...

ABSTRACT- Crop residue is applied to amend soil properties and increase crop yield. In this study, the effects of rapeseed residues and different rates of nitrogen on grain yield and yield components of sunflower and weed dry matter were investigated. The experiment was conducted at the Experimental Farm of College of Agriculture, Shiraz University, located at Badjgah, Shiraz, Iran in 2007-2008...
In order to determine the effects of water deficit stress, nitrogen fertilization and zeolite on chlorophyll fluorescence, pigments, trigonelline content and seed yield in, a split factorial experiment was laid out in a randomized complete block design with three replications. Five irrigation regimes were randomly applied to the main plots. Subplots included six treatments and consisted of a fa...
To investigate the effect of depth of planting holes on yield and yield components of three cultivars of watermelon in dry land conditions, a two-year study (2006-2007) was carried out in Varamin Agricultural Research Center, using a split plot randomized complete blocks design in three replications. Three cultivars of watermelon (Mahbube, Charleston Gray and Sugar Baby) were assigned to main p...
Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...
The experiment was completed to evaluate the responses of forage yield and silage quality of dual-purpose corn hybrids to urea fertigation. For this purpose, two studies were conducted each as a split plot experiment based on a randomized complete block design with three replications at two locations in research farms of College of Agriculture, Isfahan University of Technology, Isfahan, Iran, i...
recently, biofertilizer application is growing to meet sustainable agriculture goals. the present experiment was designed to evaluate four nitrogen levels (0, 60, 90 and 120 kg n.ha-1) as main plots, two supernitroplus biofertilizer levels) with and without biofertilizer) as sub-plots on yield and yield components of three sesame cultivars (naz, oltan and varamin (as sub-sub-plots in a split-sp...
in order to study on the effect of nitrogen, vermicompost and nitroxin biofertilizer on growth indices and phenology of sesame a field experiment was carried out at behbahan in summer of 2009. treatments were arranged in a factorial experiment based on rcbd with three replications. three rates of nitrogen fertilizer (50, 75 and 100% of region recommended nitrogen rate,) as a first factor, three...
in order to study the effects of different amounts of nitrogen and plant density on yield, yield components and seed oil percentage of pumpkin (cucurbita pepo l.) an experiment was conducted as split plot based on randomized complete block design with two factors and three replications at agricultural research field station of ferdowsi university of mashhad, iran, during growing season 2010-201...
