Modelling of Water Requirements for Some Vegetable Crops under Ismailia Conditions

Résumé

The scarcity of water resources around the globe has generated a need for their optimum utilization. Further; an agriculture consume a lot of water to irrigate crops, trees and landscape with different processes relying on climate data or soil data...etc. thus, dealing with this data help to maximizing on farm water management and rationalize unit of water. Using smart devices for irrigation management can help in achieving optimum water-resource utilization. This paper presents an open-source technology (Arduino Board) based smart algorithm, to predict the irrigation requirements using the sensing of ground parameter like Soil Moisture sensor, Real Time Clock (RTC) module, SD card module, Liquid Crystal Display. And, applied (Arduino design) at the field to irrigate a Bottle Gourd crop and comparing with CropWat model as a method for calculate the water requirement using climate data. Using Arduino device helps to rationalize a significant amount of water by 66.5mm comparing with CropWat model. Furthermore, Arduino design with algorithm model gain a good value for (IWUE) by (2.003 kg.m -3 ), (5.09 ton .fed -1 ) for Yield production. In addition; this design helping for monitoring the changing in soil water content with reducing total water applied for Bottle Gourd crop. Keywords : Arduino UNO, Bottle Gourd production, irrigation use efficiency, modeling, soil moisture, and water requirement. DOI: 10.7176/JNSR/11-20-04 Publication date: October 31 st 2020
