In order to evaluate the effect of sugarcane (Sacharum officinarum L.) filter muds and chemical and biological fertilizers application on macro- and micronutrient elements and some heavy metals (Pb and Cd) absorption by canola (Brassica napus L.) grains, a factorial experiment was conducted in 2012 in the Experimental Farm of Ramin (Mollasani) Agriculture and Natural Resources University of Kho...
Today, due to positive effect of nitrogenous fertilizers on growth, yield and quality of agricultural crops, irregular use of fertilizers is increased. In order to evaluate the effects of different sources and quantities of nitrogen fertilizers on some of physiological properties of Fenugreek (Trigonella foenum- graecum L.) medicinal plant, an experiment was carried out as a randomized block de...
an experiment was conducted as randomized complete block design with three replications and 14 fertilizer treatments in year 2014. the treatments were including the control, application of chemical fertilizers according the soil analysis, application of 15, 30 and 45 tons of municipal waste compost per ha as simple and with 25, 50 and 75% of chemical fertilizers. the results revealed that the ...
Synthetic (e.g. urea) and organic fertilizers (e.g. compost) differed markedly in N isotope composition and the greater the difference between organic and synthetic fertilizer the more robust will be the differentiation of crops and vegetable grown under different farming systems. The objective of this study was to compare nitrogen and carbon isotope composition of organic fertilizers and manur...
In order to investigate the effects of salinity stress and three nitrogen fertilizers on some traits of psyllium (Plantago ovata) plants, a factorial experiment, as completely randomized design with three replications, was carried out at University of Zabol, in 2010. Salinity at three levels (0, 100 and 200 mM sodium chloride) was the main plot and three forms of nitrogen source (nitrate from c...
