A diallel analysis of eight bread wheat (Ttriticum aestivum L.) cultivars was conducted to determine genetic parameters and the type of genetic control for yield and yield components. The parents and their F1 hybrids were evaluated in a randomized complete block design with 3 replications. General and specific combining ability effects were estimated by the method 2 of the Griffings model I, an...
Abstrac t— Predicting and understanding the dynamics of a population requires knowledge of vital rates such as survival, growth, and reproduction. However, these variables are inf luenced by individual behavior, and when managing exploited populations, it is now generally realized that knowledge of a species’ behavior and life history strategies is required. However, predicting and understandin...
A plea for linking assessment and management to the broader ecosystem state has been made several times in the fisheries literature. The need for ecosystem considerations is obvious for Baltic herring stock which has experienced large fluctuations in growth and natural mortality rate. Biological reference points, based on stock-recruitment data, have gained importance under precautionary approa...
This study was conducted to determine the virtual population analysis, recruitment pattern and cohort analysis of blue swimming crab (Portunus segnis) in coastal waters of the Persian Gulf and the Oman Sea (Hormozgan province). Sampling was carried out monthly by bottom trawl from May 2010 to October 2011. Results of Thompson and Bell prediction analysis showed that the maximum sustainable yiel...

This experiment was conducted at the Agricultural Research Farm of Isfahan University of Technology in 2006 to evaluate the effects of row spacing and plant distance on the row on yield and yield components of sunflower, Hisun-36 hybrid. A split plot layout was used with a randomized complete blocks design and three replications. Row spacing (60 and 75 cm) was the main plot and plant distance o...
Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...
In the current research, the simultaneous application of 0, 5 and 10 tons per hectare of vermicompost organic fertilizer and biochar on growth and grain yield of Camelina sativa as a factorial experiment based on a randomized complete block design with three replications in East Azarbaijan province (crop year 2020-2021) was evaluated. The highest oil yield (1073 kg/ha) was obtained in the appli...
in order to deliberate correlation coefficient between grain yield and yield components among 31 cowpea genotypes under normal irrigation (non-stress) and drought stress (water withholidng after flowering stage until maturity) an experiment was performed in a randomized complete block design (rcbd) with three replications at research field of university of tehran located at karaj during 2011-20...
in order to study the phenological and morphological characteristics, comparison of yield and yield components, correlation between traits and determination of the parameters affecting seed yield, a field experiment was carried out at the research farm of shahrekord university in 2007. ten lentil genotypes were compared by a randomized complete block design with three replications. the analysis...
