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 ...

Objective: A field experiment was conducted in order to study the effect of phosphorus and manure application on agronomic performance and seed yield of groundnut. Methods: Factorial combination of two groundnut varieties (‘Werer 962’ and ‘Oldhale’), Three rates of phosphorus (0, 90 and 180 kg P2O5 ha-1) and three rates of manur...

Spatial and temporal characteristics of Zostera marina (eelgrass) in the Barnegat Bay-Little Egg Harbor Estuary are compared before (2004-2011) and after (2012-2013) major fertilizer legislation (Fertilizer Law A2290) was enacted in New Jersey (USA) to reduce nutrient inputs from fertilizers to water bodies in the state. A significant decrease of Z. marina biomass and areal cover occurred in th...

The transport characteristics of phosphorus in soil and the assessment of its environmental risk have become hot topics in the environmental and agricultural fields. The Sanjiang Plain is an important grain production base in China, and it is characterised by serious land use change caused by large-scale agricultural exploitation. Agricultural inputs and tillage management have destroyed the so...

Excessive fertilization with organic and/or inorganic P amendments to cropland increases the potential risk of P loss to surface waters. The objective of this study was to evaluate the effects of soil test P level, source, and application method of P amendments on P in runoff following soybean [Glycine max (L.) Merr.]. The treatments consisted of two rates of swine (Sus scrofa domestica) liquid...

to study the effects of biological and manure fertilizer on quantity and quality characteristics of roselle (hibiscus sabdariffa l.), an experiment was conducted as split plot based on a randomized complete block design with three replications at the agricultural research center of zabol university, iran during growing season of 2012-2013. treatments included three manure level; 0, 10 and 20 t....

The growth and yield of Egusi melon in response to application of an Organo-mineral fertilizer was investigated. The Organo-mineral fertilizer was Cow-dung generated from an Abattoir fortified with inorganic Nitrogen. The fertilizer had a pH of 6.1; 61.2 g kg Organic Matter; 35.5 g kg -1 -1 Organic Carbon; 3.6g kg Nitrogen; 372.54 mg kg Available Phosphorus and 14.8cmol kg -1 -1 -1 Exchangeable...

In situ application of inorganic fertilizer was used to simulate environmental eutrophication associated with the sugar cane monoculture. Meiofauna community structure is herein used to assess this experimental impact. Nine quadrangular areas (4m2 each) were randomly defined in the midlittoral estuarine area. Three of these areas received a high dose of sugar cane fertilizer (375 g/m2 Nitrogen-...

this research was conducted under greenhouse conditions to evaluate the optimum combination of irrigation and fertilizer levels to attain the best yield and quality of tomato crop. the experiment was conducted by using a split-plot design with three replicates. irrigation levels were applied to the main plots and fertilizer levels to the sub-plots. for each experimental unit, the irrigation lev...
