چکیده
in order to evaluate the effects of sugar beet sowing date, planting density and cultivar on solar radiation interception, the present study was conducted in kamal-abad agricultural research station of sugar beet seed institute (sbsi) in 2005 and 2006. the experiment arranged was in split-split plots based on randomized complete block design (rcbd) with three replications. the sowing date, planting density and cultivar were assigned to main, sub and sub-sub-plots, respectively. results showed that the photosynthetically active radiation (par) rised from 8 mj.m-2.day-1 during late april and after reaching the maximum amount (17.61-17.75 mj.m-2.day-1) during june started to gradually decrease through growing season. total intercepted par (ipar) had significance differed significantly (p

متن کاملdetermination of sugar beet extinction coefficient and radiation use efficiency at different plant density and nitrogen use levels
extinction coefficient (k) is an important index that shows the rate of light decrease in canopy. net biomass accumulation is linearly related to cummulative light interception. the slope of this relationship is termed radiation use efficiency. a split plot experiment within randomized complete block design with three replications was conducted in april 2001 in sugar beet research station in ka...
متن کاملLight interception and radiation use efficiency response to narrow-wide row planting patterns in maize
The light deficiency in the canopy is not the main factor limiting maize (Zea mays L.) production but the lower radiation use efficiency (RUE). Conservation tillage planting patterns were used to construct a sustainable agricultural system for soil protection and higher RUE. On these bases, we tried to create more uniform light distribution in crop canopy for increasing radiation use efficiency...
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 کاملCanopy architecture and radiation interception measurements in olive
In this work we tested techniques suitable for a future validation of the RATP model to simulate transpiration and photosynthesis of mature olive trees under field conditions. Canopy architecture was characterised with an electromagnetic 3D digitiser and the software 3A. Although the capability of the software to deal with big data sets has to be improved, the system seems to meet the RATP requ...
