dcterms.abstract: The Irrigation Scheduling Reference Manual provides in-depth information for effectively managing agricultural water use through irrigation scheduling. This manual serves as reference material for the Standard Operating Procedure (SOP) for Developing Irrigation Scheduling.

It covers the basic principles of crop water requirements, soil-water relationships, and the role of climate in crop water requirements. It also introduces different scheduling methods – from simple visual assessments and farmer experience to more technical tools like soil moisture sensors and evapotranspiration estimates. The different scheduling methods can be used in different contexts based on local conditions, available resources, and capacity. It also emphasizes the importance of scheduling irrigation according to the crop growth stages.

The handbook focuses on participatory approaches – recognizing that farmers bring valuable knowledge, and that effective scheduling often comes from blending scientific tools with local insight. The handbook includes hands-on examples, decision-making tips, and guidance on interpreting field data, making it suitable for a wide range of users – from extension workers and planners to farmers themselves.

Based on what kind of data and resources are available, the handbook provides a toolkit for building context-specific irrigation strategies. It encourages observation, learning, and adjustment over time. The manual aims to help stakeholders in making informed decisions that support healthy crops, conserve water, and improve resilience in a changing climate.
