to determine the effects of steckling weight and planting density on seed quantitative and qualitative characteristics of monogerm sugar beet c.v. 9597, this experiment was carried out in ardabil agricultural research station in two years (1998-99). in this study, steckling weight with three different sizes(including 4.5 mm seed portion, velocity and unifomity of germination and decreasing of g...

in order to determine of the proper sowing date of steckling (rootlet) and harvesting date of seed, an experiment was conducted in ardabil agricultural research station (alarough) in 2004- 05 growing season in split-plot in randomized complete block design arrangement with four replications. four different planting dates viz. 5th march, 20th march, 4th april and 19th april– were allocated to th...

in this study, analysis of actual data collected from sugar beet hybrid monogerm seed producers in the 2001 growing season and laboratory seed samples showed that delay in steckling sowing resulted in the reduction of raw and pure sugar beet seed yield and the increase of undersize seed portion. non-significant effect of sowing dates on unkernel seed percent showed that the high temperatures wi...

in order to evaluate the effect of priming on germination of black cumin under different levels of salinity, a factorial experiment on base of completely randomized design was conducted with three replications. the main factors consisted of five levels of priming (osmopraiming with kno3 (1 and 3%), salicylic acid (sa) (0.2 and 0.5 mm) and a hydropriming)) and four salinity levels (zero, 75, 125...

the present study was conducted to evaluate the effects of these two factors as well as their interaction on seed germination of eucalyptus (e. camaldulensis). a factorial experiment based on a completely randomized design with three replications was used. five salinity levels including 0, 50, 100, 150, 200 mm sodium chloride were tested on seed collected at top, middle and bottom of the tree. ...

                In order to determine the best developmental stage of three common bean cultivars (Talash, COS16 and Khomain) at which maximum seed quality is attained under different irrigation regimes (I1-irrigation after 60 mm, I2-irrigation after 80 mm and I3-irrigation after 100 mm evaporation from class A pan), a split plot experiment (using R.C.B. design) with 3 replications was conducte...
