Conducting research on monitoring contaminated fields by heavy metals is necessary in order to achieve sustainable agriculture, increase product quality and keep public health. This study was carried out using split plot experiment based on randomized complete blocks design with three replications during 2014-2015 in Shavor Agricultural Research Center in order to evaluate the effect of croppin...

A field experiment was conducted to evaluate the residual effect of rock phosphate and waste mica enriched compost on phosphorus and potassium supplying capacity under soybean crop grown after wheat in a Typic Haplustept. Enriched compost prepared using rice straw, rock phosphate, waste mica and Aspergillus awamori had higher chemical (total P, K, Ca, Mg and micronutrients) as well as biologica...

In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150...

Effects of organic manure (poultry manure) applied alone and integrated with inorganic fertilizer (urea) on yield and yield component, N-uptake and soil fertility in wheat-maize cropping system was evaluated in a field experiment at Nuclear Institute for Food and Agriculture, Peshawar, Pakistan. Poultry manure was applied alone and were integrated in different proportions with mineral nitrogeno...

Chemical based phosphate (PO4-3) fertilizers occupies significant place in agricultural domainand ought to be dangerous (e.g. cause chronic kidney disorders, eutrophication). Hence, world isyelling for an efficient substitute of PO4-3 fertilizer. This fertilizer is being used escalate yieldof green leafy vegetables, which are loaded with health nutrients, consequently, fallingfor this Mediterra...

This experiment was laid out in order to evaluate the effects  of different biofertilizers on yield components of barley. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate  biofrtilizers (Phosphate barvar2, Biozarr and Superplass) with control for them and yield components we...

A cover crop management trial in butternut squash was planted at the Forgotten Harvest Ore Creek Farm (9153 Major Rd, Fenton, MI 438430) in a Miami loam soil with a 02% grade. The objectives were to determine how yields following a cereal rye cover crop were affected by three tillage systems and three at-plant fertilizer treatments in a split-plot Randomized Complete Block Design with four repl...
