| Abstract Information on radiation use and physiological development such as leaf area of crops planted under screen-house and ambient environments is very scarce in the sub-Saharan part of Africa, This research therefore was aimed at investigating the radiation use of tomato under screen-house and ambient environment with a view to determine its leaf area index (LAI) under different irrigation water treatments: 100% Field capacity (100%FC), 75% FC, 50% FC and rain-fed condition in ambient environment. AccuPAR LAI 80 Ceptometer (Decagon Device) was used for direct measurement of the Above and Below canopy Photosynthetic Active Radiation, Fraction of beam inception (Fb), leaf distribution coefficient (chi), leaf area index (LAI), zenith angle θ, and ratio of... |
