Lesson notes

Learning Objectives

Indicator: 2.1.3.LI.4 - Use the appropriate irrigation system to produce arable crops (cereals, legumes, and tuber crops).

By the end of the lesson, learners can:

Match each type of irrigation system (surface, sprinkler, drip, centre pivot, lateral move, sub-irrigation, manual) to the arable crop enterprise (cereals, legumes, or tuber crops) for which it is best suited, with reasons.
Set up a simple drip irrigation system and a simple sprinkler system using locally available materials on a school plot.
Irrigate a selected arable crop using the appropriate method, applying the correct water amount and frequency for that crop’s stage of growth.
Monitor soil moisture and crop response after irrigation, recording observations in a simple log book.
Justify their choice of irrigation system for a given crop, farm size, water source, and budget during a group presentation.

Content standard: 2.1.3.CS.1 - Demonstrate knowledge and skills in the use of various forms of irrigation systems in arable crop (cereals, legumes, and tuber crops) enterprises. 1.1.3.LO.1 Compare the production of crop enterprises (cereals, and tuber crops) under rainfed agriculture and irrigation. 1.1.3.LO.2 Explain the roles of farm machinery and equipment in arable crop (cereals, legumes, and tuber production.
Indicator: 2.1.3.LI.4 - Use the appropriate irrigation system to produce arable crops (cereals, legumes, and tuber crops).
Suggested placement: Semester 1, Week 14 (Week 14 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Experiential Learning: Embark on field trips to farms or gardens that use modern forms of irrigation e.g., Sprinkler, Surface irrigation - where water is distributed over and across land by gravity without mechanical pump, localised irrigation, drip irrigation, centre pivot irrigation, lateral move irrigation, sub-irrigation and manual irrigation.
Project-Based Learning: Practice irrigation using the various forms mentioned above on selected arable crop (cereals, legumes, and tuber crops).
