Mazandaran province is an important area in rice cultivation but salinity is one the biggest constraint to obtain crop potential yield in some part of the coastal line of rice cultivated area in northern Iran. In order to find tolerant varieties and study the reaction of some newly released high yielding varieties to different levels of salinity of irrigation water a Factorial experiment was c...
ٍearly watergrass (echinochloa oryzicola (ard) fisher) is an aggressive specie of echinochloa and have mimicry chareterstics of rice . in order to evaluate competitive effect of aggressive specie of echinochloa on rice, an experiment was conducted at the rice research institute of rasht during 2007. the experimental design was complete randomized block with three replications. the treatment incl...
Observations of naturally occurring stem rust epidemics and seed yields in perennial ryegrass were taken in 19 field experiments conducted over the course of 9 years. Epidemic severity differed among years and also among experimental treatments (fungicide regimes) within years. In each experiment, attainable yield was represented by the nondiseased treatment, and yields of other treatments were...
The strategy for increasing the palatability of Hanwoo beef through fattening could lead to a decline in yield grade. The aim of this study was to examine the meat quality traits of Longissimus dorsi (LD) muscle from carcasses of Hanwoo steers at different yield grades. A total of 246 Hanwoo steers was divided into the following yield grades: A (n=77), B (n=76) and C (n=93). Meat quality traits...
