The radiation interception and transmission in strip intercropping system
2023Intercropping, growing at least two different crop species simultaneously in the same field, is a significant cropping system for global food security with more practice and attention recent years. The most remarkable advantage of intercropping is producing a higher yield or income due to more efficient use of agricultural sources.

Mobile Radiation Source Interception by Aerial Robot Swarms
2019 International Symposium on Multi-Robot and Multi-Agent Systems (MRS), 2019This paper presents a motion planning approach to track a moving target for the purpose of classifying its radioactivity properties, using a team of micro aerial vehicles (MAV). The team falls into an optimal, from a sensing perspective, formation around the target and collectively decide, within seconds, if the target is even weakly radioactive.

Radiation interception, radiation use efficiency and growth of barley cultivars
Australian Journal of Agricultural Research, 1993Dry matter production and utilization of photosynthetically active radiation (PAR) was studied for barley (Hordeurn vulgare L.) in the field at Hermitage Research Station, Qld. In 1990, four cultivars (Gilbert, Tallon, Grimmett, Skiff) were sown at three times and grown with non-limiting soil moisture. In 1991, soil moisture limitations were imposed on

Radiation Interception, Radiation Use Efficiency and Crop Productivity
2016Photosynthesis is the set of processes whereby radiant energy is converted and stored as chemical energy in most plants, algae and cyanobacteria. This process depends on radiation, temperature and CO2 concentration. The maximum efficiency of the process is 6 % but it is usually well below.

Dry Matter Production and Radiation Interception of Potato
Crop Science, 1991The quantification of radiation‐use efficiency (RUE), the amount of dry matter produced per unit of intercepted photosynthetically active radiation, is important for yield modeling and determination of yield potentials in different environments. This study was conducted to determine the mean RUE value of potato (Solanum tuberosum L.) and its stability ...

Cultivars of Arabica coffee: Characterization and interception of solar radiation
CABI Reviews, 2023Abstract The importance of coffee crops in the global agricultural scenario goes beyond economic aspects, also encompassing political and sociocultural factors. Brazil stands out in this scenario as the largest producer and exporter of coffee in the world, with a particular emphasis on the state of Minas Gerais. Coffee production

Intercepted Radiation at Flowering and Kernel Number in Maize
Agronomy Journal, 2000When water and nutrients are not limiting growth, kernel number per plant (KNP) can be calculated for maize (Zea mays L.) using linear models based on intercepted photosynthetically active radiation per plant (IPARP). These models do not include the concept of a threshold IPARP for KNP.

Interception of photosynthetically active radiation by cacti of different morphology
Oecologia, 1980Ribbing, orientation of cladodes, and variations in stem height were examined theoretically and in the field to see whether the morphology of various cacti could be interpreted as adaptations for intercepting photosynthetically active radiation (PAR). The total daytime PAR incident on different parts of the stem was related to the nocturnal increase in

Modelling and measurement of radiation interception by olive canopies
Agricultural and Forest Meteorology, 2000We present the formulation, calibration and validation of a model to estimate photosynthetically active radiation (PAR) intercepted by olive (Olea europaeaL.) canopies. The model calculates the PAR transmittance at any point located within the four central trees of the orchard.

The effect of leaf-lobing on the interception of direct solar radiation
Oecologia, 1989The extent to which leaf-lobing influences the interception of direct solar radiation by individual plants was studied by means of computer simulations. The morphology, size and orientation ofAmbrosia artemisiifolia L. leaves were measured and used to construct a prototypeAmbrosia plant upon which a computer simulation was based. The leaf geometries of
