water shortage and its consumption resulted in development of a suitable rice cultivation system which use less water. therefore, this preliminary research was carried out to study the possibility of coversion of irrigated system of rice cultivation to aerobic. we tested 61 aerobic rice genotypes, in which were developed at international rice research institute (irri), together with 3 diverse l...

due to variation in economic value of different varieties of rice, reports indicating the possibility of mixing different varieties on the market. applying image processing and neural networks techniques to classify rice varieties is a method which can increase the accuracy of the classification process in real applications. in this study, several morphological features of rice seeds’ images we...

a study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. two lines were crossed with five testers in line × tester fashion to produce 10 f1 hybrids. analysis of variance revealed significant differences among genotypes and cros...

The use of soil as one the main factors in manufacture agricultural products for human consumption must be carried out using right basis and scientific principles. One ways to achieve this important goal is assess land suitability common crops study area. It also necessary determine product compatibility based on climate conditions reduce risk investment because there no history studied plant’s...

the use of resistant cultivars remains one of the most reliable methods to manage the pests. in this study the mechanism of resistance in 10 lines of rice for 3 kinds of resistance (antixenoses, antibioses and tolerance) was studied. the egg set of striped stem borer on the leaf of considered lines for antixenoses and larva weight mean and survival percentage of larva were evaluated for antibio...

papaverfugax poiret population tarom was shown to contain one major alkaloid, mecamberine (0.4%), and six minor alkaloids, roemerine, pronuciferine, protopine, thebaine, nornuciferine and salutaridine. nornuciferine was detected for the first time in p. fugax

to evaluate of rice genotypes in various modified systems, an experiment was carried out as split plot in randomized complete blocks design with four replications at neka region, mazandaran province, iran in 2011-2012. cropping systems were chosen as main plots including conventional, improved and system of rice intensification (sri) and genotypes as sub plots including: sang tarom, hashemi tar...
