Smart Phone Evapotranspiration-Based App for Optimal Irrigation Scheduling for Thai Crops

Thailand is known as a top producer of many essential agricultural commodities including canary seeds, cassava, mango, mangosteen, guava, and chili pepper. Due to global warming and population growth, droughts are increasing and water is becoming scarce, which have a direct impact on agriculture. Farmers are therefore facing difficulties in supplying their crops with sufficient water due to water scarcity and the increasing irrigation cost. This situation calls for optimal use of irrigation water in agriculture, which is sufficient to avoid crop water stress and at the same time help to sustain water and reduce irrigation expenses.
