| Abstract: Automate drip irrigation in greenhouse was conducted at Elhssen Agriculture Authriuts, Giza governorate, Egypt. The aim of this researcher is to use the new Laser Leaf Control Unit (LLCU) as a tool to operate the automate drip irrigation system in greenhouse. Comparative study between Laser Beam Transmit (LBT) build in the (LLCU), different temperature (dt) and Soil Moisture Content (SMC) were carried for irrigated cucumber. Three instruments used; 1) Laser Leaf Control Unit (LLCU); 2) Infrared Thermometer (IR) used to measure canopy temperature around plant leaf (Tc) and air temperature (Ta) to estimate dtc °C; 3) Soil Moisture Meter (SMM) to measure Soil Moisture Content (SMC). The result exhibited that there is a relationship between the LBT,... |
