Exploring Crop Production and Management: Engaging DIY Activities for High School Teachers & Homeschooling Parents
Welcome to our DIY activity blog post designed specifically for high school teachers and homeschooling parents. In this guide, we will present three exciting hands-on activities that will educate and inspire students to delve into the world of crop production and management. These activities are designed to foster curiosity and promote a deeper understanding of agricultural practices. Let's get started!
A crop is a group of plants grown together at a place on a large scale. It is usually grown for commercial purposes. The two main types of crops in India are: Kharif crops; grown in the rainy season. Eg; Paddy, maize. « Rabi crops; grown in the winter season. Eg; wheat, pea.The following steps are involved in crop production and management and are known as ‘Agricultural practices’ :
Activity 1: Seed Selection
Teaching the importance of seed quality and selection for successful crop production.
- Ragi seeds
- transparent container
- Begin by gathering ragi seeds and examining them for any signs of damage or defects. Mix the seeds with water in a glass.
- Observe the behavior of the seeds in water and note that damaged seeds tend to float, while healthy seeds sink.
- Take the healthy seeds into the transparent container Discuss with the students the significance of choosing high-quality seeds for optimum crop growth and yield.
Did you find some seeds floating above, while others sink to the bottom of the container? The seeds that float are damaged seeds. This is because damaged seeds become hollow and light while the good seeds will be dense due to accumulation of nutrients from the plant during its growth. Thus, you can easily separate and remove the bad seeds from the good ones. Later fill the coir pots with little soil and put the good seeds , then fill the rest of the pot with soil .
Be the Techy frame:
Any plans on beginning a garden of your own using good seeds? Install Seeds-planting on your device to guide you through plantation of seeds; when and how, what more should be done etc. Get appropriate instructions and contribute to a better yield!
Now that we have successfully selected seeds, is it time to sow them in the soil? Before we sow the seeds, we need to ensure that the soil is good enough to hold them and give a good yield. The nutritional quality of the soil is affected by various factors such as pH,availability of nutrients such as nitrogen, potassium, phosphorus, etc; texture of the soil, organic matter, soil-water relations, and so on. Among these, nitrogen content is one major influential factor. The levels of nitrogen in the soil depends on the ‘Nitrogen cycle’ The cycle explains the movement of nitrogen from the atmosphere into organic forms, which is later incorporated into plant matter.
Activity 2: Nitrogen Testing
Explore the role of nitrogen in plant growth and learn basic soil testing techniques.
- Soil samples
- testing tubes
- nitrogen capsules
- nitrogen soil testing chart
- Collect soil samples from different locations, ensuring a variety of soil types.
- Mix the soil with water in a 1:2 ratio and transfer a portion into a testing tube.
- Add a nitrogen capsule to the sample in the testing tube and mix thoroughly.
- Use the nitrogen soil testing chart to determine the percentage of nitrogen in the sample.
- Engage students in a discussion about the importance of nitrogen for plant growth and the significance of soil testing in crop management.
Activity 3: DIY Drip Irrigation System
Introduce the concept of efficient water management through a hands-on model.
- Small tube
- small tap
- grass, coir cups.
- Take a small tube with a small diameter and connect a syringe to one end of the tube.
- Create small holes at equal intervals along the length of the tube using a pin or needle.
- Attach a small tap to the other end of the tube.
- Hold the syringe in a vertical position and slowly push the plunger to simulate water flow.
- Observe as water drips from the holes in the tube, representing a DIY drip irrigation system. Explain the advantages of drip irrigation, such as water conservation and efficient nutrient delivery to plants
