Objective: An experiment was performed in Ardabil (2012) to investigate the effects of manure consumption in different amounts on reducing nitrogen fertilizer consumption in potato cv. Agria. Methods: This research was conducted in factorial design based on randomized completely blocks design in three replication  in which two manure factors in three levels (control, 30 and 60 tons/h) and nitro...

to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...

BACKGROUND: Wheat produces more than 50 percent of requirements protein and calorie for human nutrition in Iran. Management of nitrogen fertilizing is important to increasing wheat production. So, among chemical fertilizer a high correlation reported between nitrogen and yield. Also to improve physical, chemical and biological properties of soil, organic fertilizer such as verm...

The present research was conducted to mitigate the environmental contamination and with the aim of evaluating the possible impacts of the application of sugarcane bagasse sewage sludge-based compost (BSC), vermicompost, and fish compost on different aspects of physiology, growth, and development of Lilliumlongiflorum var Ceb-Dazzle. The bulbs were planted in four different prepared soil mixture...

this experiment was conducted to study the effects of single and combined application of organic, biological and chemical fertilizers on qualitative and quantitative characteristics of vegetative part of coriander, (coriandrum sativum l.). the experiment was carried out as split plot in time based on complete randomized block design with three replications and 12 treatments at research station,...

in order to study the effects of drought stress and organic fertilizers (compost and vermicompost) on some physiological and biochemical characteristics of borage, an experiment with complete randomized block design in split plot arrangement with three replications was conducted in zabol university, zabol, iran. the treatments included 3 levels of stress as a witness or 100% of field capacity, ...
