Objective: In this study investigated effects of different amounts of pelleted manure with urea and micro elements on yield and seed quality of medicinal plants, pumpkin (Cucurbita pepo var. styriaca). Methods: The animal manure and urea as pellet with four levels (150 Kg urea, 50 Kg urea + 3.5 ton animal manure, 100 (Kg) urea+ 1.5 ton animal manure and 150 (Kg) urea+1.5 ton animal man...

The Haber–Bosch process for the commercial production of ammonia demonstrated in 1913 was a watershed event in the mass production of urea, the principal nitrogen fertilizer for modern agriculture. Today, thanks to the so-called “green revolution” starting in in the 1960s, nearly half of the world population relies on increased crop yields, through the use of nitrogen fertilizers, to access aff...

in order to investigate the effects of different levels of nitrogen and phosphorous fertilizers on flower yield , yield components and some quality components of german chamomile, a factorial experiment based on a randomized complete block design with four replications was carried out in the medicinal plant research farm of shirvan college of agriculture during growing season of 2007-2008. nitr...

management of soil fertility via biological fertilizers inoculation is one of the most important components based on sustainable agriculture. in order to investigate the effects of biological and chemical fertilizers on yield and some morphological traits of forage yield sorghum, a field experiment was conducted as factorial based on randomized complete block design with three replications at a...

The drawbacks to multivariate charting schemes is their inability to identify which variable was the source of the signal. The multivariate exponentially weighted moving average (MEWMA) developed by Lowry, et al (1992) is an example of a multivariate charting scheme whose monitoring statistic is unable to determine which variable caused the signal. In this paper, the run length performance of m...

BACKGROUND: Nutrients play a very important role in chemical, biochemical, physiological, metabolic, geochemical, biogeochemical, and enzymatic processes. Innovations for saving water in irrigated agriculture and thereby improving water use efficiency are of paramount importance in water-scarce regions. Conventional deficit irrigation is one approach that can reduce water use w...

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 ...

In order to investigate the effect of urea, Azocompost and cutting on growth characteristics of Oregano, a factorial split-plot experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 kg N.ha-1 each) for Yazd location )0, 43.5, ...

in order to study the effects of different irrigation system and different amounts of nitrogen fertilizer on yield and quality of sugar beet, an experiment was conducted at ekbatan research station, hamedan during 2005-2006 as split plot based on randomized complete block design  with three replications. the main plots were irrigation systems (furrow, sprinkler and drip irrigation) and subplots...
