irrigation water and nitrogen fertilizer are two important factors in increasing the yield and yield components of cotton. in order to evaluate effects of irrigation methods, various levels of water and nitrogen fertilizer on yield and yield components of cotton were studied at hashemabad cotton research station of gorgan in 2008. the experiment was conducted in split-split plots design with th...
A study was conducted in 2007 to investigate the effect of nitrogen fertilizer rates (0, 30, 60 Kg ha-1) on some agronomic characteristics, seed yield and oil percentage in three Sesame(Sesamum indicum L.) cultivars (Dashtestan, Darab 14, and Zarghan) in Kaki region (Bushehr Province). The type of design was completely randomized block with factorial arrangement and three replications. Nitrogen...
In order to study the effects of terminal heat stress and nitrogen on morphophysiological characteristics, ANUE (Agronomical Nitrogen Use Efficiency) and yield of canola, an experiment was conducted at research farm of Ramin Agricultural Sciences and Natural Resources university. The experiment was arranged in split plots based on randomized complete block design with four replications. Main pl...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...

Corn production management including nitrogen consumption will be different at different circumstances. In order to investigate the effect of different levels of nitrogen fertilizer on yield and yield components of seed corn hybrids in Khuzestan weather conditions, this research was carried out in the summer of 2013 in the lands of Safi Abad Agriculture and Natural Resources Research Center-Dez...
objective: an experiment was performed in ardabil (2012) to investigate the effects of manure consumption in different amounts on reducing nitrogen fertilizer consumption in potato cv. agria. methods: this research was conducted in factorial design based on randomized completely blocks design in three replication in which two manure factors in three levels (control, 30 and 60 tons/h) and nitro...
This study was carried out under temperate climate condition of Ilam province, Iran, during 2012-2013 growing season to determine the suitable crop rotation for enhancing nitrogen uptake, utilization, and use efficiency of wheat. A two factor experiment was laid out as split plot arrangement (RCBD) with four replications. The main plots consisted of 6 pre-sowing plant treatments (control, Perko...
