in order to study the effect of different nitrogen fertilizer rates and source-sink limitation treatments on yield and yield component of contrast rice (oryza sativa l.) cultivars, a field experiment was carried out in the rice research institute of iran-deputy of mazandaran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 f...
This study was carried out in order to determine the more suitable seedling age on rice cultivars in Chaparsar Rice Research station of Mazandaran province in 2009. This experiment was laid out as split plot in a randomized complete block design with 3 replications. The main plots were seedling age with four levels (20, 33, 37 and 40 days) and sub plots were rice cultivars (Hashemei, Khazar, hy...
Simplifying the selection procedure to improve yield of new genotypes of rice is necessary. in order to evaluate relationship among grain yield and other agronomic traits, an experiment was conducted in agricultural and natural resoures research center in 2015-2016 year. In present study, 10 rice genotypes were studied in randomized complete blocks design with three replications. Grain yield al...
A field experiment was conducted during 2001-2003 to evaluate the effect of water stress on the yield and yield components of four rice cultivars commonly grown in Mazandaran province, Iran. In northern Iran irrigated lowland rice usually experiences water deficit during the growing season include of land preparation time, planting, tillering stage, flowering and grain filing period. Recently d...
This study aimed at evaluating the effect of different planting dates (different ambient temperature conditions) on the characteristics of rice panicle and yield of its cultivars in Khuzestan climate in 2010. The experimental design was a split plot in a Randomized Block Design with four replications. The main factor was the planting date with three dates (May 25th , June 9th , and June 25th ) ...
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 conditions. The objectives of this study were to analyze the ...
In order to investigate the effects of water deficit stress on grain yield and some traits three sunflower cultivars, have been used based on randomized complete block design using a split plot experiment at Agricultural Research Station of Azad University of Tabriz in 2007. Five levels of water deficit (50, 100, 150, 200 and 250 mm evaporation from evaporation pan, class A) were assigned as m...
the aim of this study was to investigate the genotype effect on nitrogen remobilization and its relationship with yield and grain protein concentration in genotypes of wheat during grain filling. twelve wheat cultivars different in origin and varying with grain yield and grain protein percentage were selected. a randomized complete block design was used. plants were harvested at anthesis and ma...
In order to assessment of relationships between effective traits on grain yield and also determination of cause and effect relationships between of them, 121 native and exotic cultivars available in the collection of Rice Research Institute of Iran were evaluated in a simple lattice design (11×11) with two replications for 12 important agronomic traits. The results of analysis of variance showe...
In order to investigate the best planting time and rice cultivars for the conditions in Khuzestan Province, seven high quality cultivars of rice namely Domsiah, Binam, Ramasanali Tarom, Sang Tarom, Hasansarai, Tarom Mahalli, Daylamani and Anboori were selected and studied in 4 planting dates starting in Mid-May, with intervals of 15 days. The experiment was conducted as a split plot design in r...
