nitrogen is the primary nutrient that shows deficiency in saline areas, therefore, proper nitrogen fertilizer management is one of the strategies to achieve higher wheat grain yield.  a field experiments in a saline soil was performed on wheat with a factorial arrangement in randomized complete block design with four replications, in rostagh area, 25 km from yazd. the first factor was nitrogen ...

in order to study the effects of nitrogen fertilizer on yield and growth of soybean (glycine max l.) an experiment as factorial in rcb design with three replications was conducted during 2006 and 2007 years at north khorasan. factors were cultivar (hobbit, l.w.k., and williams), and nitrogen fertilizer (0, 50, 100, and 150 kg n/ha from urea source). results indicated that cultivar and n fertili...

Centrifugal fertilizer spreaders are by far the most commonly used granular fertilizer spreader type in Europe. Their spread pattern however is error-prone, potentially leading to an undesired distribution of particles in the field and losses out of the field, which is often caused by poor calibration of the spreader for the specific fertilizer used. Due to the large environmental impact of fer...

The research described in this report was conducted as part of the Brown County Waste Transformation Initiative (BCWTI). The BCWTI is a public-private partnership of various stakeholders in northeast Wisconsin that is exploring methods of improved solid waste utilization through the development of commercially viable products that are appealing for public use. Many of these materials are curren...

OBJECTIVE The study aimed to assess the N use efficiency (NUE) of pig slurry (in comparison with chemical fertilizer) for each regrowth yield and annual herbage production and their nutritive value. METHODS Consecutive field experiments were separately performed using a single application with a full dose of N (200 kg N/ha) in 2014 and by four split applications in 2015 in different sites. Th...

due to importance of nitrogen on the agronomic traits of linseed oil, a factorial experiment was conducted in randomized complete block design with three replications at the field research station of faculty of agriculture at shahrekord university in 2012. five different treatments of fertilizer including urea, azomin, nitroxin, supernitroplus and control (without nitrogen) as the first factor ...

more nitrogen use efficiency in crops is important for maintaining and developing sustainable agriculture. in order to study the effect of different levels of mushroom compost and different resource of nitrogen on yield, yield attributes and nitrogen use efficiency of wheat (triticum aestivum l.), an experiment was conducted at faculty of agriculture, ferdowsi university of mashhad, iran, durin...
