Abstract
A new resource capture model, RESCAP, (Monteith, in press), places equal
emphasis on the role of leaves in relation to the interception of light and to the role
3
of roots in relation to the uptake of water. A central feature of the model is the
comparison each day beiween the accumulated extractable water and the net
decrease of soil water content since the start of growth. If the demand in the plant
system is met from the available soil water then dry matter production is a function
of intercepted light (light-limited), but if the demand exceeds supply, the rate of
transpiration reverts to total potential extraction by the root system (water-limited).
Post rainy season provides excellent conditions to validate a crop model and this
study entitled "Interaction of water and nitrogen in relation to growth and yield of
rabi grain sorghum" was framed to achieve the following objectives:
