introduction water consumption improvement in agriculture is very important compare with other sections. because of existing complexity in production and exploitation processes and optimized application of irrigation water and nitrogen especially in dry and semi-dry areas facing with water constraint is an important goal in this field. yield gap analysis can help to identify how much yield incr...

introduction: this study was conducted to determine the pattern of maxillofacial fractures in three age groups of adults, adolescents, and children, using ct scan images. methods: in this cross-sectional study, ct scan images of 230 patients with maxillofacial trauma during one year were examined in terms of the number and site of fractures. the patients were divided into three age groups, chil...

Abstract The quality of the nursery media is very important to producing healthy and good Robusta coffee seeds. This study aims improve seedlings by application arbuscular mycorrhizal fungi (AMF) rock-phosphate (RP). AMF as first factor consisted four levels, namely 0, 5, 10, 15 g/polybag, while second RP 1.25, 2.50, 3.75 g/polybag. Each treatment was repeated three times whole treatments were ...

in order the the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis) an experiment in split plot randomized based on complete block design with three replications in 1393 at the agricultural research station of roudehen islamic azad university done. treatments were first factor drought in four levels (control, stress at vegetative stage, stress at flowering stage...

to evaluate canola cultivars response to physiological characteristics and grain yield end seasonal drought stress in weather condition of ahvaz, farm experiments were done at research farm of khuzestan agriculture and natural resources center. during 2007-2008 and 2008-2009 crop years. farm test comprised drought stress was done as split plot form with randomize complete block design with four...

ABSTRACT Environmental conditions can influence herbicide metabolism and interfere with the evolution of weed resistance. This study aimed to evaluate effect thermal regimes on control barnyardgrass (Echinochloa crus-galli) susceptible resistant herbicides imidazolinones chemical group. Factor A (biotypes) consisted one biotype that is imazethapyr; factor B (dose) comprised six imazethapyr dose...

to study the effects of different levels of water stress and nitrogen fertilizer on seed yield and yield components of two common bean genotypes (phaseolus vulgaris), an experiment in a split plot factorial based on crbd with four replications was conducted at the research farm of university of tehran (karaj-iran) in 2010. water stress treatments as the main factor included normal irrigation (6...

this study was carried out in the agro-industry complex of gohar kouh, khash in iranshahr. a split-plot experiment based on rcbd was employed with three irrigation intervals including 1: 30 day interval 2: 40 days of irrigation interval 3: 60 day irrigation interval along with three levels of nitrogen application including 1: no nitrogen fertilizer 2: 750 grams of nitrogen fertilizer per tree 3...

The effect of bio-fertilizers and super-absorbents on the modification water-deficit stress was studied in castor. A field experiment conducted with a split-plot design based completely randomized block three replications. first factor included four levels (70, 100, 130, 160 mm evaporation pan Class) main plot; sub-factor application bio-fertilizer treatments (Azospirillum, Citrobacter, Azospir...
