Abstract:
CORONA is a spatially explicit model designed to efficiently estimate the quantity of shortwave radiation intercepted by individual tree crowns. Radiation interception is determined from intersections of light rays with tree crowns for rays originating throughout the sky hemisphere. CORONA comprises a flexible, asymmetric description of crowns, a computationally efficient ray-tracing procedure, numerical solution of ray × crown intersections, and several alternative within-crown light interception functions. The interception functions were calibrated and evaluated in two plots located in black

Abstract:
The study on radiant energy distribution in guava was carried out to optimize the planting density with respect to solar radiation interception by the plants to get higher yield of good quality fruits per unit area. The present investigations reveals that with increase in plant spacing from 6x2m to 6x4m the interception of radiation increased significantly during both rainy and winter crop seasons. However, it starts declining with further increase in plant spacing to 6x5m level. The interception of radiation remains somewhat static during the summer and rainy season months (May-September) and

Abstract:
Horticultural tree crop yields tend to be linearly correlated with the percentage of photosynthetically active radiation (PAR) intercepted by the canopies, at least for part of the PAR interception range. Models of PAR interception by hedgerows have been used in the design of orchards for temperate tree crops, especially apples, but not for subtropical tree crops, such as lychee and macadamia. Subtropical crops need special consideration because of the latitudes at which they are grown, the specific shapes and dimensions of the hedgerows, and the evergreen habit, which requires an understandin

Precision drilling established a more uniform plant distribution than øyjord drilling; visual differences observed soon after emergence were not observed at flowering.

AbstractEstimating the interception of radiation is the first and crucial step for the prediction of production for intercropping systems.

Abstract:
Abstract This chapter focuses on developing general model of community growth and the production of yield by grain crops. Murata's (1969) three-stage system provides such a model. It is useful because it is simple (only three stages), it applies equally well to all grain crop species (although there are some species variation in minor details), it clearly identifies the sequential nature of the yield production process and the three stages relate to the primary drivers of the yield production process at the community level. First, the crop must accumulate the leaf area that drives community photosynthesis (Stage I), then seed number is determined (Stage II), and finally seed filling occurs (Stage III) and the production of yield is finished. High yield of any variety/location combination requires, at a minimum: (i) the production of enough leaf area index (LAI) during Stage I to maximize solar radiation interception and community photosynthesis; and (ii) an absence of stress during Stage II to maximize seed number and during Stage III to allow the seeds to fill to their maximum potential size. The scheme provides a powerful framework for us to think about how management decisions and environmental conditions affect yield.

Abstract:
Light-emitting diodes (LED) are advancing the development of indoor vertical farming due to their varied light spectrum and photon flux density. The substantial energy cost of lighting systems requires improvement. This chapter reviews three major spectra applied to lettuce cultivation in indoor vertical farming systems. Red and blue light are the most efficient spectra for chlorophyll absorption and far-red light promotes light interception and increases photochemical efficiency. Research shows that the photon flux ratio between red and blue light affects plant architecture, leaf and photosynthetic characteristics, biomass production and phytochemical compound accumulation. Additional far-red over photosynthetically active radiation triggers shade avoidance responses and increases light interception, which combines with planting density effects. Aside from the above spectra, biomass production and quality, utilization of other light spectrum and dynamic lighting as well as plant modelling should be considered to promote light use efficiency in indoor vertical farming.

Abstract:
Abstract A well intercept operation has the scope to drill into an existing well. Similarly, some infill drilling operations are conducted with the scope of avoiding interception with other wells. A prototype of a tool for Active Magnetic Ranging While Drilling (AMR) without the use of a wireline operation has been developed. The main scope of the current article is presenting the results of a prototype test of this new tool in attest well. The ranging tool emits a low frequency alternating current into the formation to reach the target well, and then run through that's casing back to the well
