Development of application tools for determining cropping patterns based on water availability

Abstract

Innovative irrigation is a vital factor in increasing water efficiency, gaining benefits, and reducing environmental burdens. Fulfilling irrigation water demand appropriately from time, space, quantity, and quality is the main factor in the irrigation water distribution pattern. A simple information system process, transparent and real-time reporting can reduce water sharing conflicts and improve irrigation operator performance. This research aims to determine the planting area refers to water availability through an automatic calculation application, where the water distribution is carried out based on the condition of the plant’s water demand at that time and several days after. The process of collecting the latest data by installing sensors or recording devices related to the analysis of water demand and availability parameters, such as climatological conditions, plants, and water in the rice fields and their sources, was needed as an input process the application. When the automation of operations operates, sensors on the rice fields plots send information directly to data companies that perform information analysis and send agronomic instructions to machines that regulate the release of the amount of water to the motion weir (smart agriculture management system). The way for determining the planting area and planting pattern calculated using the calculation application of the irrigation water demand, which developed with potential evapotranspiration values, reliable rain (R80), crop coefficient (Kc), and dependable discharge data (Q80) as the input data. This system’s output data consist of a table of irrigation water demand, a graph of the relationship between irrigation water demand and discharge availability for a year.
