BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Improve saving water in irrigated agriculture and thereby improving water use efficiency is of paramount importance in water-scarce regions. OBJECTIVES: This study was conducted to assessment effect of different levels of irrigation re...

Mineral nitrogen (N) fertilization in cereals is commonly split into three or four applications. In order to simplify N fertilization, a single N application either broadcast or placed on the soil surface was compared to conventionally split fertilization for winter wheat (Triticum aestivum L.). The 4-year experiment (2007-2010) was performed using a participatory approach on farmers' fields on...

The paper presents an account of a ®eld plot experiment to investigate the in ̄uence of soil applications of neem-based (Achook and Suneem G) and crop fertilizer (urea and cattle manure) treatments, separately and in combination on free-living, and plant-pathogenic nematode populations and crop productivity. All the treatments signi®cantly decreased the number of plant-parasitic nematodes with i...

a split plots experiment based on randomized complete blocks design was carried out at field research center of islamic azad university, shoushtar branch during 2012 to find out the suitable sowing date and urea fertilizer used in chamomile (matricaria recutita). main plots including three sowing date (9, 19 and 29 february 2012) and subplots including four levels of urea fertilizers (5, 10, 15...

Farmer in different parts of Ethiopia uses a similar type fertilizer and amounts that are below the crop requirements, even low soil fertility which limits production general. To solve over-blanket application over agroecology Ethiopian Soil Information System (EthioSIS) mapped recommended types for specific location. A NPSB where Beko village, but rate this was not studied so far. So, field ex...

in order to investigate the effect of vermicompost (vc) application on amount of micro elements in soil and plant organs of the medicinal plant of borage (borago officinalis), an experiment was carried out in split plot based on complete randomized block design with three replications in the research farm of the sari university of agricultural science and natural resources. fertilizer treatment...

Highlights The Integrated Farm System Model appropriately represented average emission rates measured in corn production. Compared to the use of feedlot manure, application bedded pack manure generally increased N and P losses. inorganic fertilizer use, cattle soluble loss while reducing GHG emission. Production environmental differences among production systems were similar under recent future...

Abstract High quality turfgrass requires adequate amounts of nitrogen (N) fertilizer. However, excess N application can increase losses via leaching and gaseous emissions. Enhanced efficiency fertilizers (EEF) humic substances have been used to decrease the environment. A two‐year field experiment was conducted on a native soil with Kentucky bluegrass ( Poa pratensis L.) investigate if addition...

Salicylic acid (SA) is a phyto-hormone that regulates physiological and biological processes in plants and can be used to improve plant growth under different environmental conditions, including water stress. Thus, a field experiment as split plot factorial based on randomized complete blocks design with three replications was conducted in 2014 to investigate the effects of fertilizer and salic...
