high nitrogen and plant density cause increasing vegetative growth and reducing harvest index. the objective of this study was to evaluate the effect of cycocel at high nitrogen and plant density on safflower yield and yield components. for this purpose a field experiment was carried out as a factorial-split plot based on randomized complete block design with three replications with esfahan 14 ...
in order to evaluate plant density and different nitrogen levels on protein percent, yield and nitrate accumulation in potato tuber cv. agria, a factorial experiment based on randomized complete block design with three replications was conducted in ardabil in 2006. factors included nitrogen levels: 0, 80, 160 and 200 kg ha-1 net nitrogen and plant densities: 5.5, 7.5 and 11 plant m-2. results s...
To evaluate the effects of different levels of nitrogen (N) and salinity on yield and growth indices of tomato, a factorial experiment with a completely randomized design and three replications was performed in greenhouse conditions. Treatments included four levels of salinity (0.5, 2.5, 4.5 and 6.5 dS/m as NaCl) and four levels of N (0, 60, 120 and 240 kg/ha). The results showed that fruit yie...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
plant population density (ppd) and nitrogen (n) have large effects on chickpea growth and yield. to study these effects on chickpea (var. kourosh) a factorial experiment (4×3) in randomized complete block design with four replications was carried out at research farm of college of agriculture & natural science, karaj (iran) in 2006. four ppd treatments were 16, 32, 48 and 64 plant m-2 and n amo...
To study the effect of cycocel, nitrogen and planting density on nitrogen (N) content, remobilization and use efficiency of Esfahan 14 safflower cultivar, a field experiment was carried out as a factorial split-plot based on randomized complete blocks design with three replications at Research Farm of College of Agriculture, Yasouj University, in summer of 2010. Main plots were the factorial ...
In this study, the effects of nitrogen fertilizer and plant growth regulator (ethephon) application on leaf chlorophyl, stem height and diameter, stalk yield, total sugar and bioethanol of sweet sorghum were determined. Four nitrogen treatments 0, 100, 200 and 300 Kg Urea ha-1 and four ethephon concentrations 0, 800, 1000, and 1200 ppm were applied on sweet sorghum in a split plot on randomized...
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...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
Among soil and agronomic factors affecting growth, nutrition and plant density have a great effect on the growth and yield of crops such as Flax (Linum usitatissimum L.). In order to study the effect of different levels of nitrogen and plant density on yield and yield components, oil percentage and yield of Flax, a split plot experiment was conducted in a randomized complete block design with f...
