this study was conducted to determine the effect of variable nitrogen supply on yield parameters of two sugar beet varieties, as well as on biomass allocation to different parts of sugar beet plant at safi-abad agric. res. center during 2003-4 and 2004-5. five nitrogen rates (0, 60, 120, 180 and 240 kgha-1) and two monogerm sugar beet varieties (shirin and rasol) arranged as factorial in a rand...

pishgam was selected from the progeny of a cross between barakat iranian bread wheat cultivar and chinese 90-zhong 87 winter-habit ( bkt/90-zhong 87) in 1995. the f1 generation seeds were planted in karaj station in 1995-96 cropping season. selected-bulk method was applied to segregating generations from f2 to f5 generations for characters such as winter hardiness, plant height, straw strength,...

research was conducted during 1999 to 2009 to develop and introduce a new common millet (panicum miliaceum) cultivar suitable for areas with short growing seasons in iran. several common millet populations collected from different locations of iran were evaluated in research farm of seed and plant improvement institute in karaj and based on yield, agronomic traits and tolerance to abiotic stres...

plant analysis is successfully used in monitoring nutritional status, recommending fertilizer rates and types, and maximizing fertilizer efficiency in sugar beet. diagnosis and recommendation integrated system (dris) is a comprehensive approach which does not have limitations of the critical value approach (cva) and sufficiency range approach (sra). over- dose application of fertilizer increase...

in the present study, twenty two selected lines from eleven iranian eggplant (solanum melongena l.) landraces along with varamin landrace, as control, were studied in a randomized complete block design with three replications in three locations (karaj, varamin and dezful). sum of yield and marketing score for each line was recorded. analysis of variance for yield showed significant differences ...

tomato is the most important agricultural crops in bushehr province. this experiment was conducted on a randomized complete block design (r.c.b.d.) with 15 treatments cultivars and 4 replications in the borazjan research station during two consecutive cropping seasons (1995-97) to find tomato cultivars with high yield and quality and suitable for the region. cultivars had been selected among 60...
