Use of
infrared thermometer for water stress detection in faba bean
Mahmoud F. Ahmed , Ibrahim Dawi and Omer H. Ibrahim
Abstract:
Response of two faba bean (Vicia faba L.) cultivars, viz H72 and BB7 to
water stress was studied by subjecting them to water stress duration for
24 days at vegetative stage (S1), flowering or pod set (S2) and pod
filling stage (S3) in a field experiment conducted for two successive
seasons (1998-99 and 1999-00) at Hudeiba Research Station Farm. The
different treatments were arranged in a factorial randomized complete
block design. Vegetative growth attributes, reproductive structure
abscission and crop phenology were examined. Soil moisture content,
actual and potential daily evapotranspiration and crop coefficient
values for different growth stages were monitored. Water use efficiency
(WUE) was also calculated. The infrared thermometer was calibrated with
the gravimetric method for soil moisture detection. The modified Penman
equation was correlated with the canopy temperature difference (CTD).
They were found to be well correlated (r = 0.94) and can be used for
detection of water stress in faba bean.
