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...

Abstract This study investigated the effects of seaweed extract (SWE) made from brown algae Durvillaea potatorum and Ascophyllum nodosum on plants soil. The application SWE to soil growing tomato showed dual effects. comprehensively improved plant growth (flower clusters, flower number, fruit root length, shoot dry weight, SPAD) increased productivity (yield quality). Similarly, effected biolog...

Damask rose (Rosa damascena Mill.) is one of the most high-value essential oil-bearing plants in the world. However, the flower yield and quality of essential oil of R. damascena are largely influenced by the pruning practices and balanced supply of plant nutrition. The objective of this study was to test the hypothesis whether the pruning system and foliar fertilization of MgSO4 would influenc...

Background and Aims: Climate variation contributes to fluctuations in reproductive output, and spring temperature is thought to influence flower production in grapevines. For 3 years, we studied the influence of temperature from before budswell through to the appearance of individual flowers on reproductive development in field-grown Cabernet Sauvignon while minimising the influence of other mi...

introduction: in iran, tuberose is ranked the forth after gladiolus, rose and carnation. these flowers are known as high quality products among which maximum exportation belongs to tuberose and gladiolus. in plant cultivation and development, adequate provision of nutrients is of crucial importance. tuberose needs plenty of nutrients to obtain the desirable quality and flowering. hence, tuberos...

The crop will be free from the control of apical dominance and axillary buds develop into branches after topping. However, there are relatively few studies on this subject soybean. In order to further improve soybean grain yield, unbranched type high-yield variety was used as test material, effects topping at first trifoliate stage plant growth, dry matter accumulation, yield components five pl...

using plant growth regulators at the stresses environment can improve plant growth and crop production. hence, in this research response of photosynthesis rate, chlorophyll, soluble sugar and flower dry weight of chamomile to methyl jasmonate under different salinity levels was studied. values of 0 (control), 75, 150, 225 and 300μm methyl jasmonate (meja) with salinity levels of 2, 6, 10 and 14...

An experiment was conducted at the research farm of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh, during November 2013 to April 2014 to determine the growth and yield performance of four varieties of black cumin (Exotic variety, BARI kalozira-1, Faridpur local and Natore local) as influenced by three levels of fertilizers ...
