This study compares, on a simulator, drivers' performance (eye fixations and yielding behavior) at marked mid-block crosswalks in multi-threat scenarios when the crosswalks have advance yield markings and pedestrian crosswalk prompt signs versus their performance in such scenarios when the crosswalks have standard markings. Advance yield markings and prompt signs in multi-threat scenarios lead ...

A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...

Phosphorus (P) addition ameliorates the adverse effects of water stress on seed yield soybean (Glycine max L.). Previous studies focused effect P root traits, but little information is available changes to aboveground traits. In this paper, we show how affects shoot traits and reduces yield. Two genotypes, with contrasting architectures, were grown in pots compare canopy architecture, leaf dry ...

water deficiency is one of the most important factors for limiting crop yield in arid and semiarid regions. symbiosis with a variety of microorganisms in these regions is one of the modern ecological approaches for sustainable agriculture to reduce damages caused by environmental stresses. symbiotic of arbuscular mycorrhizal fungi (am) with the roots of crops has shown positive effects on agric...

in order to study the intercropping of barley (hordeum vulgare l.) and faba bean (vicia faba l.) an experiment was conducted as factorial based on randomized complete block design with two factors and three replications at sari agricultural science and natural resources university during 2009. the first factor was two seed ratios include d1: 75 and 150 kg.ha-1 of faba bean and barley, respectiv...

oilseed pumpkin is an introduced medicinal plant, the seeds as well as some other organs of which are being utilized in treating an array of human diseases in iran. considering the plant's significance in the health products' industry on the one hand, and the countrywide drought stresses and a lack of information on mineral nutrition of the oilseed pumpkin, the present study was aimed...

BACKGROUND A better understanding of the relationship between stand structure and productivity is required for the development of: a) scalable models that can accurately predict growth and yield dynamics for the world's forests; and b) stand management regimes that maximize wood and/or timber yield, while maintaining structural and species diversity. METHODS We develop a cohort-based canopy c...

The effect of temperature on ligand photodissociation from protoheme and the heme proteins hemoglobin (Hb) and myoglobin (Mb) has been examined. The quantum yield of photodissociation (phi) is greater at 40 degrees than at 0 degrees; in general, larger increases are seen in the less photosensitive complexes, while phi does not change in the most photosensitive complexes. The ratio of phi at 40 ...

The continuing depletion of nutrients from agricultural soils in Sub-Saharan African is accompanied by a lack of substantial progress in crop yield improvement. In this paper we investigate yield gaps for corn under two scenarios: a micro-dosing scenario with marginal increases in nitrogen (N) and phosphorus (P) of 10 kg ha(-1) and a larger yet still conservative scenario with proposed N and P ...
