In order to examine the effects of plant density on the morohological traits, yield and essential oil of peppermint, an experiment was conduced in Agricultural College of Tabriz University during 2005 and 2006. The treatments included four plant density levels ( 8,12 ,16,20 plants.m-2) with three replications. The treatments were based on a split plot design in time and result analysis of compo...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
in order to evaluate the effect of water stress and plant density on growth and seed yield of safflower, a study was conducted during 2009 growing season at agricultural college of shiraz university. the experimental design was split plot based on randomized complete block design with three replications. the treatments were deficit irrigation (100, 75, and 50% of field capacity-fc) as main plot...
in order to determine the responses of morphological characteristics, yield and yield components of rapeseed (brassica napus l.) to plant density and weed interference duration, a factorial experiment was conducted using a randomized complete block design with 3 replications at the rice research institute of iran (rrii) in rasht, in the 2008 growing season. the factors comprised plant density a...
To evaluate the effect of different concentrations of humic acid on guar (Cyamopsis tetragonoloba L.) yield and nutrient uptake in different sowing densities, an experiment was carried out by using a split plot design with three replications based on a randomized complete block design, in Agricultural Sciences and Natural Resources University of Khuzestan, Iran at summer 2016. Experimental fact...
to evaluate the effects of planting date and plant density on morphological characteristics, including essential oil content of ajowan (trachyspermum ammi) a study was conducted during the years 2003 and 2004 at the experimental farm, faculty of agriculture, ferdowsi university of mashhad. treatments were laid out in a factorial form based on a complete randomized block design of three replicat...
according to the contradictory reports of researchers, tillers may have positive or negative effect on wheat yield. thus, this study was conducted to investigate the role of tillers on wheat yield under two row spacing of 12.5 and 25 cm and four plant densities of 125, 250, 375 and 500 plants per m2, at gorgan university of agricultural sciences and natural resources farm in anbare-ololum reign...
To study the effects of planting date and density on yield and its components in chickpea (Cicer arietinum L.) genotypes under dryland conditions of Khorram-Abad, an experiment was conducted during 2005-2006 growing season at the Agricultural Research Station of Lorestan Weather Department. Three sowing dates (March 6, March 21, and April 5) and two chickpea genotypes (Greet and Flip 93-93) wit...
