Due to increasing scarcity of fresh water, use of unconventional water source (e.g., wastewater) in irrigation has now become important. However, inclusive information on the effects of wastewater on crop production and soil health is necessary for such intervention. This study was designed to evaluate these effects by demonstrating the contribution of municipal wastewater (hereafter called was...

this study aimed at evaluating some quantitative and qualitative properties of potato as one of the main commercial products in iran. to this end, a split plot experiment on the basis of randomized complete bloke design with silicone and iron was carried out in jiroft as one of the commercial area of planting potatoes. the main factor included different levels of silicon (0, 10, 20, 30 mm.l-1) ...

this study set out to investigate the effect of bio-fertilizers containing nitrogen-fixing bacteria and phosphorus on grain yield and yield components of faba bean. to this end a factorial experiment on the basis of randomized complete block design with four replications was conducted in behbahan region at south eastern part of khuzestan province of iran. the experimental treatments included ni...

estimated at 4.0 to 4.5 t ha 1 (Illy, 1997; Wopereis et al., 1999), and in general two crops per year are grown. Development of improved fertilizer recommendations entirely based This compares to average yields in the Sahelian and on field experiments is time-consuming and costly. We employed a comSavannah regions of 3.0 to 5.5 t ha 1. The cropping bination of two simulation models and selected...

Traditional rice cultivars in Sri Lanka conserve different abiotic and biotic tolerant traits but the yield of traditional rice cultivars is not as much of improved cultivars. Abiotic stress tolerance of some traditional rice cultivars were evaluated in previous studies at Faculty of Agriculture, Mapalana, Sri Lanka and this study attempted to understand the possibility of enhancing the yield a...

to evaluate the effects of phosphate solubilizing bacteria and chemical phosphorous fertilizer on turnip (brassica rapa) forage yield under limited irrigation regimes, a field experiment was conducted in research farm of college of agriculture and natural resources, university of tehran, in karaj/iran during 2009 growing season. the experimental treatments were arranged as split plots. five lev...

Treatments to reduce solids content in liquid manure have been developed, but little information is available on gaseous N emissions and plant N uptake after application of treated liquid swine manure (LSM). We measured crop yield, N uptake, and NH3 and N2O losses after the application of mineral fertilizer (NH4 NO3), raw LSM, and LSM that was decanted, filtered, anaerobically digested, or chem...

The effect of seed inoculation by phosphate solubilizing microorganisms and different levels of phosphorus chemical fertilizer on yield and yield components of barley (Karoon x Kavir cultivar) was studied in Experimental Farm of College of Agronomy and Animal Sciences, University of Tehran during 2006-2007 growing seasons. The experimental treatments were arranged in split plot factorial based ...
