In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...

    In order to investigat e of Tobacco germplasm genetic diversity, 49 genotypes were grown in Tobacco Research Institute (Rasht, IRAN) as a simple lattice design 7×7 with 2 replications and 12 treatments were evaluated as well. Correlation analysis to studied traits showed that Fresh leaf yield with leaf number, leaf length, leaf width, leaf area index, plant height, flowering period and days...

Leaf diseases’ influence the relationship between the yield and yield components of winter wheat (Triticum aestivum L.). Field experiments were conducted during 2003–2006 on a light loamy gleyic cambisoil in the central part of Lithuania to determine how leaf disease severity level affects grain yield and yield components. The area under disease progress curves (AUDPC), grain yield and yield co...

This study was conducted to evaluate the genetic diversity of sugar beet half sib inbred lines (48 lines and one control cultivar) under water stress (200mm of class A evaporation pan) in field conditions in a randomized complete block design with three replicates in Khorasan Razavi Agricultural and Natural Resources Research and Education Center in 2015. In this research, traits such as root y...

Mulberry (Morus spp.) is a perennial tree cultivated for its foliage to rear the domesticated silkworm, Bombyx mori L. Mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. Leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for ...

Previous research indicates a correlation between leaf area index (LAI) and yield of full-season soybean [Glycine max (L.) Merrill], which is a single crop planted early in the season. Leaf area index values of at least 3.5-4.0 in the reproductive stages are required for maximum potential yield. It is unknown how yields of double-crop soybean, which is planted late into harvested small grain fi...

The effects of different levels of nitrogen (100, 200, 300 and 400 mg/L) and potassium (125, 250 and 375 mg/L) on yield and leaf N and K concentrations of tomato were investigated in perlit culture using a factorial randomized design with three replications. The highest fruit yield was obtained with 200 mg/L N. Higher levels of nitrogen decreased tomato yield. With increasing nitrogen concentra...

                The present study was undertaken to evaluate direct and indirect selection criteria for the improvement of grain yield and quality components in Chenopodium quinoa Willd. Correlated response (CR) and relative selection efficiency (RSE) were estimated for grain yield and three quality components, grain protein, grain carotenoid and leaf carotenoid based on different contributing ...
