in order to study the effect of irrigation interval, n fertilizer and superabsorbent on yield and qualitative traits of sesame (sesamum indicum l.), a split-split-plot experiment was coducted in a farm in khusf of birjand, iran in 2009 on the basis of a randomized complete block design. the main plot was devoted to irrigation interval at three levels of 6, 12 and 18 days, the sub-plot was devot...

in order to evaluate row spacing and microelements spraying on yield and some morphological traits ofpeppermint, a split plot experiment was conducted based on randomized complete block design with fourreplications in sari agricultural sciences and natural resources university during 2010-2011. threelevels of row spacing (50 × 10, 50 × 20 and 50 × 30 cm) and two levels of microelements (no spra...

in order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of goldasht spring safflower cultivars (carthamus tinctorius l.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the agricultural research station of islamic azad university of roudehen branc...

in order to study the effects of different irrigation levels on yield, yield components and drought tolerance of four chickpea cultivars, a farm experiment was conducted in mashhad climatic condition during 2008-2009 growing season. four irrigation levels including: t1= 100% etc (full irrigation), t2= 90% etc (deficit irrigation), t3=80% etc (deficit irrigation) and t4=50% etc (deficit irrigati...

this experiment was conducted at the agricultural research farm of isfahan university of technology in 2007-2008 to evaluate the effects of seed treatment and the levels of irrigation regimes on three safflower cultivars. a split plot factorial arrangement was used in a randomized complete block design with three replications. main-plot consisted of three irrigation regimes (60, 105 and 140 mm ...

Abstract This research aims to study the effect of number harvest rows under two digging depths and cultivars on quality harvesting potatoes (damage losses). The experiment was factorial, using a randomised complete block design with split-split plot three replications for each treatment. types were placed in main plot, type digger secondary split depth plot. results showed no significant diffe...

abstract- crop residue is applied to amend soil properties and increase crop yield. in this study, the effects of rapeseed residues and different rates of nitrogen on grain yield and yield components of sunflower and weed dry matter were investigated. the experiment was conducted at the experimental farm of college of agriculture, shiraz university, located at badjgah, shiraz, iran in 2007-2008...

in order to study the effect of irrigation and nitrogen fertilizer levels on yield of basil, an experiment was conducted as split plot based on randomized complete block design with three replications in birjand (moud region) in 2010. main plot factor was two irrigation levels (7 and 14 days interval) and nitrogen fertilizer (as urea) was considered as sub plot factor in four levels (0, 50, 100...

a field experiment was conducted to study the physical properties of maize grain in response to different urea fertilization methods (urea foliar spraying and soil application), three harvest times (grain moisture content of 20, 30 and 40 pecent) in four maize hybrids (three foreign hybrids e.g. ns640, jeta600 , konsur580 and one common hybrid, sc704 as control) at khorram abad agricultural res...
