in order to evaluate the morphological characteristics and lodging related traits and carbohydrate content of culm and carbohydrate remobilization in traditional and improved rice cultivars, a field experiment was laid out in randomized complete block design with three replications at rice research institute of iran )rasht( in 2012 and 2013. rice genotypes included three native rice cultivars (...
spiders are the powerful and efficient predators in almost all ecosystems which have effective role in different pest control. the fauna of these arthropods was surveyed during 2005-2009, and their population fluctuations and activities were studied in mazandaran paddy fields in 2005-2006. a total of 53 spider species of 44 genera were collected and identified from paddy fields of mazandaran pr...
Effect of nitrogen (N) fertilizer levels and its split applications on yield and yield components of rice (Oryza sativa L.) Cv. Khazar was investigated in a completely randomized block design with 3 replications in a paddy light soil at Guilan province, Iran, 2003. In this experiment, six treatments including: T1-control (no N fertilizer) T2- 40 kg/ha N (at transplanting time) T3- 80 kg/ha N (a...

this study was conducted to evaluate the water-use efficiency of rice (khazar cultivar) at rasht research institute of rice. the treatments were four different irrigation intervals (two, five, eight and 11 days) in a randomized complete block design (rcbd) with three replications. the plot size was 15 square meters in area and 50 cm in depth. the spacing between plants was 25 x 25 cm and the so...
* 1 Department of agronomy and plant breeding, College of Agricultural, University of Guilan, Guilan, Iran *Corresponding Author: [email protected] Abstract: In order to evaluate the effect of Pseuodomonas different strains on nutrients uptake efficacy and rice yield, an experiment was arranged in Rice Researches Institute of Guilan Province (Rasht) during 2009. The experiment...
Rice bacterial blight caused by Xanthamonos oryzae pv. oryzae is one of the most destructive bacterial diseases of rice in some areas of rice cultivation in the world, especially in the tropics of Asia. The low efficiency of disease management methods, especially chemical methods, has led to more research on recognizing resistant cultivars and understanding resistance mechanisms through the stu...
in order to investigate rice competition ability against weeds in direct-seeding and transplanting systems afield experiment was conducted at mahmud abad region of mazandaran province on 2011 growing season. experimental treatments were studied in a split plot factorial design based on randomized complete blocks with three replicates. direct-seeding and transplanting of rice in wet seedbed were...
in this study, the spatial distribution of overwintered adults of sunn pest, eurygaster integriceps puton, was investigated by using dispersion parameters and indices, mathematical distribution, and regression techniques in rainfed wheat fields by sample size of 1 m2 in 2009 and 2010. the dispersion parameters including: mean-variance test and clumping parameter () showed that the overwintered ...
