Dense planting effectively increases maize yield while increasing stalk lodging risk. Appropriate row spacing can improve the population structure and resistance, but its physiological ecological mechanisms interaction with density are unclear. Here, a two-year field experiment to determine joint effects of on stem characteristics quantitative relationship light condition within resistance indi...

lignin is one of the major characteristics of plant secondary cell wall that provides structural rigidity for the cells and tissues and hydrophobicity to tracheary elements. internode tissues of aeluropus littoralis as a halophyte grass were sampled at different developmental stages (from the first to the fifth internodes ) and under different nacl concentrations. the influences of nacl and int...

in order to evaluate the interference effect natural population weeds and plant density, an experiment with randomized complete block design in factorial arrangement with 4 replications was conducted in 2006 in a field experiment at ramin agricultural and natural resources university, khouzestan. treatments included two factor, plant density of corn at three levels (4, 7 and 10 plants m-2) and ...

in order to evaluate the effects of different plant densities and nitrogen levels on growth, yield and qualitative characteristics of marigold, a field experiment was conducted as split plot based on randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, during growing season of 2008-2009. main and sub plots were four nitro...

to evaluate the effects of sowing density, deferred harvesting, and harvest intensity on forage yield and an some vegetative characteristics of annual medic (medicago scutelatta var robinson) an experiment was conducted on the research farm of college of agriculture ,university of tehran ,karaj, during 2005 growing season. the expremental treatments were arranged in split-split plots based on a...

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...
