Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Measurement of solar radiance demands expensive devices to be used. Alternatively, estimator models are used instead. In this paper, a new method based on the empirical equations is introduced to estimate the monthly average daily global solar radiation on a horizontal surface. The proposed method uses Intelligent Water ...

in order to evaluate physiological and morphological characteristics and yield of soybean (glycine max l.) cultivars under different planting ratios a field experiment was conducted based on randomized complete block design with four replications at the gaem shahr agricultural research centre of mazandran province, iran, during 2008. two soybean cultivars (032 and sari) were planted in row inte...

The Earth is continually exposed to the cosmic radiation of both solar and galactic origin. Solar eruption and solar activity may affect cosmic radiation flux density which has a secondary effect on the flux of particles in the atmosphere as well. Such one event was recorded in the last week of October 2003, where the measured dose rate of the cosmic radiation in the aircraft ATR 42 was 1.8 tim...

to study the effect of plant density and planting pattern on iranian ox-tongue, an experiment carried out with two factors: planting pattern (square and rectangular pattern) and plant density (2, 4, 6, 8 plant m-2) in a factorial test performed based on rcbd in 3 replications during 2009-2010 in latmahalleh eshkevarat village in guilan province, iran. characteristics that measured included: dry...

although self incompatibility in walnut has not been reported, but the dicogamy limits self pollination of walnut cultivars. as the density of female flowers produced by the tree is low, if a high fruit set occurs, yield especially in terminal bearing cultivars will not be high. so breeding of a pollinizer cultivar with proper pollen shading period is highly necessary for increasing fruit produ...
