Growth and N Fixation of Some Tropical Forage Legumes as Influenced by Solar Radiation Regimes
Decreased solar radiation due to cloud cover or shading by plantation crops or associatedass can severely limit the production of tropical forage legumes. We therefore evaluated the response of six legumes (three replicated and three not replicated) to four radiation regimes (100, 70, 45, and 27% of unshaded solar radiation, hereafter termed "full sun") with polypropylene netting in the field. ...
متن کاملeffect of sowing date, planting density and cultivar on solar radiation interception indices in sugar beet. ii. radiation use efficiency
in order to evaluate the effect of sugar beet sowing date, planting density and cultivar on solar radiation interception, a study was conducted in kamal-abad agricultural research station of sugar beet seed institute (sbsi) in 2005 and 2006. the experimental design was split-split plots based on randomized complete block design (rcbd) with three replications with two sowing dates as the main pl...

متن کاملModelling and measurement of radiation interception by olive canopies
We present the formulation, calibration and validation of a model to estimate photosynthetically active radiation (PAR) intercepted by olive (Olea europaea L.) canopies. The model calculates the PAR transmittance at any point located within the four central trees of the orchard. The spatial and time integration of this process allows calculation of PAR transmitted to the ground and, thus, the P...
متن کاملSolar Energy Potentials and Radiation Map of Lorestan Province
Solar energy is the most unique renewable energy source in the world and is the main source of all energy on Earth. Solar energy can be converted into other forms of energy directly and indirectly. In general, the energy given off by the sun about 3. 8 two 1023 kW per second. In the present study, the potential of solar energy in the province of surveillance data 9 synoptic stations located in ...
