in order to study the effects of plant density and nitrogen rates on yield, nitrate and protein of silage maize (ksc 704) in shahrekord area, an experiment was conducted during 2007 growing season at the agricultural research farm of shahrekord university. the experimental design of the experiment was randomized complete blocks with factorial arrangement with four replications. treatment consis...

to investigate the effect of sowing density and growth habit on yield, yield components and weed community of red bean an experiment was conducted at research farm of zanjan university, during 2009. the experiment carried out using factorial-split plot design in completely randomized block arrangement with three replications. the main plots, included three red bean cultivars (goli, sayyad and d...

research on crop response to deficit irrigation is important to reduce agriculture water use in areas where water is limited resource. using drought resistant landraces with irrigation scheduling based on phenological stages in semi-arid and arid regions may provide an opportunity to optimize irrigation efficiency and water savings in these regions. in order to evaluate of yield and yield compo...

in order to determine radiation use efficiency and phenological and physiological characteristics of three maize hybrids on seven plant densities, an experiment was conducted during 2006 growing season in mashhad, iran. three maize hybrids including late-rippening maize (704), medium-rippening (504) and early-rippening maize (260) and seven plant densities including d1=3, d2=5, d3=7, d4=9, d5=1...

the anatomical and epidermal characteristics, as well as the physiological response, of 'colombia' ecotype cape gooseberry plants treated or untreated with foliar applications of kaolin at 2 irrigation levels (well-irrigated plants vs. water-stressed plants) were evaluated. relative water content (rwc), stomatal density, and chlorophyll index were reduced under water stress. water stress increa...

to investigate the effect of wild mustard plant density and nitrogen fertilizer on morphological characters, yield and yield components of canola a split-plot experiment based on a randomized complete block design with 3 replications was carried out in bu-ali sina university of hamedan, in 2009. 4 levels of nitrogen fertilization (100, 150, 200 and 250 kgn h-1) were assigned to main-plots and p...

in order to evaluate plant density and cultivar effects on rate and process of grain filling, yield and yield components of three dry bean cultivars a factorial experiment (using r.c.b. design) was conducted in 1386 at agricultural and natural research center of east azarbaijan (tabriz). three cultivars (khomeyn, g-14088 and 11816) were planted at four densities (14, 20, 30 and 60 plants/m2) in...
