to study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (medicago scutellata cv. robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (sararood dryland agricultural research institute and soil fertility research station in mahidasht) during 2009 growing season. the experimental treatments consi...

Finger millet is extensively cultivated in the tropical and sub-tropical regions of Africa known to save lives small income farmers from starvation at times extreme drought. Therefore, this field experiment was carried out study integrated effect vermicompost inorganic fertilizer blended NPSB with urea on yield components finger millet. Treatments consisted four levels (25, 50, 75, 100%) three ...

The application of urea fertilizer has always been associated with heavy N losses therefore, improving its efficiency is critical to minimize economic and environmental losses associated with its application. One possible approach to improve the nitrogen losses from the surface applied urea is to coat it with sulfur, urease inhibitor (agrotain) and other biodegradable materials. A pot experimen...

Efficient management of fertilizers and irrigation could mitigate greenhouse gas (GHG) emissions increase crop yields. Field experiments were conducted to determine the effects an integrated plant nutrient system (IPNS) water regime—alternate wetting drying (AWD) continuous flooding (CF)—on GHG rice yield. Fertilizer treatments included control (no N), prilled urea (PU), deep placement (UDP), I...

Nutritional management is an important factor in the success of crop production. In order to evaluate different level of nitrogen, potassium and zinc fertilizers on agro physiological characteristics of green bean a field experiment was conducted as split-plot based randomized complete block design in three replications, in Varamin university field research during 2011. The main plot included u...

A study on six plots of corn was conducted on the St. Andrews School farm near Townsend, DE to compare the runoff water quality characteristics between pelletized broiler litter (PBL) and conventional fertilizers, in this case urea. The objective of this comparison was to see whether or not PBL is a suitable replacement for conventional fertilizer. Within the six corn plots, three of the plots ...

to study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at college of agriculture, shaheduniversity in tehran, 2011. the main plots were allocated to different levels biofertilizer...

The revolving algal biofilm (RAB) system is a wastewater treatment method that effective at removing nutrients from wastewater, and as result produces algae could be used sustainable fertilizer source. A two-year greenhouse study was conducted to investigate if algae-based fertilizers produced the RAB an turfgrass fertilizer. Fertilizer treatments included pure (PA), + cellulosic filler (Blende...

BACKGROUND The aim of this study was to evaluate the effects of nitroxin biofertilizer and chemical fertilizer on the growth, yield, and essential oil composition of dill. The experiment was conducted under field condition in randomized complete block design with three replications and two factors. RESULTS The first factor was the concentrations of nitroxin biofertilizer (0%, 50%, and 100%) o...
