the purpose in this research was to study the effects of vermicompost and poultry manure on yield and yield components of the medicinal plant coriander (coriandrum sativum l.) in the shahr-e- ghods region. a factorial experiment using the randomized complete block design with three replications was conducted in the islamic azad university of shahr-e- ghods. the first factor was three levels of ...

in order to investigate effects of optimum use of manure and nitrogen fertilizer on yield and yield components of corn single cross 704 (late maturing, non-prolific and dent) in different levels of irrigation water. a field study was conducted in 2005 year in agriculture experiment station of college agriculture, arak university (34o 32′ n, 50o 31′ e; 1759 m above mean sea level). design of exp...

In In order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (RCBD) with 4 replications in Saat-Loui agricultural station of West Azerbaijan province. In this research, the first factor (A) contained two levels 20 and 40 cm inte...

water scarcity in arid and semi-arid climate of iran has made deficit irrigation as a strategy for optimal water use and conservation in agricultural sector. this study aimed at evaluating the effects of water-deficit stress and n fertilizer levels on sugar beet performance. the study was conducted in split block design based on randomized complete block design arrangement. the row factor consi...

This experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in Iran. The experiment was a factorial design with three replications. Treatments were four nitrogen biofrtilizers (control (N1), Nitroksin (N2), Azotobacter (N3) and Supernitroplat (N4)) and three phosphate biofrtilizer...

This study investigates the sensitivity of design variables such as ultimate strength of concrete, yield stress of reinforcing steel and damping ratio to the seismic response of staggered wall structures. Two different methods for sensitivity analysis, the tornado diagram method and the first-order second-moment method, are applied to two types of model structures. Non-linear dynamic analyses a...
