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

This study was conducted to investigate the effects of processing aids and techniques such as talcum powder (2% w/w), calcium carbonate warm water dipping (45 °C), combined treatment (warm dipping+2% carbonate) control (without adding aid) on extractability quality ‘Tarom 7’ olive oil randomized complete block design with three replicates. The results showed that there were no significant diffe...

in order to evaluate the effect of ducks number on weeds diversity and density in paddy fields, an experiment was conducted at sari agricultural sciences and natural resource university during growing season of 2011-2012. experiment was arranged in split plot based on complete randomized block design with four replications. main factors were duck number at three levels (consisting of control, 4...
