چکیده
Rice product after wheat has special importance as the second agriculture strategic product. Rice weevil as one of the most important stored pest has the main role in losses of stored product. So in this research, the pest effects was studied on 4 common varieties of rice in Guilan province "Taroum, Hashemi, Ali kazemi and Dylamani" in two conditions of facultative and obligatory nutrition. Results showed that Taroum variety was the most sensitive variety in conditional of facultative and obligatory nutrition and after it Hashemi variety was in the second category and had significant difference with Taroum variety. Ali kazemi and Dylamani varieties didn’t have significant difference with together and had the lowest sensitive. [Seyedeh Masoomeh Hasheminia.

Bipolaris oryzae causes rice brown spot disease which reduces rice yield with substantial global impact. Streptomycetes isolated from rice fields of Guilan Province, Iran, showed antifungal activity against the tested pathogen. From five active Streptomyces spp. isolates, isolate G showed high antagonistic activity. To determine its taxonomical identity, its colonies character...
متن کاملResponse of different rice cultivars (Oryza sativa L.) to water-saving irrigation in greenhouse conditions
Due to increasing water and growing demand for food a more efficient water use system is needed for agriculture. This is more evidence for rice production with a higher water use for economical production. A large cultivar×water regime interaction exists for grain yield in rice. Therefore, information is required to adopt new rice cultivars with high yield potential under water-saving condition...
