Abstract A field experiment was conducted to investigate the influence of agricultural machines (AM) LDSM and Nordsten planting depths (PD) on wheat/ Abu-Ghraib 3 cultivar. The included two types AM (LDSM Nordsten) three PD levels (PD1 6, PD2 8 PD3 11 cm) application. split -split plot arrangement in RCBD with replications used, results indicated that (Nordsten type) major impact than all studi...

in order to investigate the indices of drought tolerance, correlation coefficient and path analysis at deficit irrigation and nitrogen experiment, this experiment was conducted as split plot arranged in a randomized complete block design (rcbd) with three replications during 2000-2003 for wheat at maragheh agricultural research station of dari. the treatments were included four levels of defici...

to study the effect of planting dates and genistein application on nitrogen content and nodulation of three annual medic species (medicago polymorpha cv. santiago m. rigidula cv. ragidula, and m. radiata cv. radiata), an experiment was conducted during 2005-2006 in the research farm of faculty of agriculture, shahed university, tehran. the treatments were arranged as split split plot in a rando...

due to limitation of conventional water resources, the use of unconventional water for agriculture is unavoidable. therefore, in order to investigate the effect of using different amounts of municipal wastewater on yield, yield components and water use efficiency of cotton in drip irrigation systems, a field experiment was carried out during 2010 and 2011 growing season at experimental farm of ...

this research was conducted to evaluate the effect of different nitrogen and zinc combination on grain yield and its component in maize by path analysis. this experiment was carried out through split plot based on rcbd, varieties as main plot and fertilizers as sub plot, with three replication at badjgah (experimental farm of shiraz university). nitrogen fertilizer in (120,260 and 400 kg/ha) an...
