Inferring Transpiration Control from Sap Flow Heat Gauges and the Penman-Monteith Equation [PDF]
Transactions of the ASABE, 2012 In situ measurements of crop transpiration can enhance field studies of crop water use and productivity. Our objectives were to develop and evaluate a canopy resistance model, to evaluate operational characteristics of sap flow heat gauges (SFHG) for field corn (Zea mays L.), and to compare transpiration flux calculated by SFHG with evapotran ...

Irrigation demand modelling using the UKCP09 weather generator: lessons learned [PDF]
, 2013 The determination of irrigation demand is typically based on crop modelling using a long historic record of local daily weather data. However, there are rarely adequate weather station records near to given sites; often any local records cover a limited ...

Design of Fuzzy Controller Based on Penman-Monteith Equation for Drip Irrigation
International Journal of Recent Technology and Engineering (IJRTE), 2019 The agriculture sector plays vital role in overall socio-economic status of India. The involvement of Indian population in agriculture and associated activities is 54.6% (census 2011). The net cropped area is 43% of entire geographical region of India and area under irrigation is 68 million hectares.
