Answer:
We check the soil moisture regularly and water plants based on their needs. We use drip irrigation for efficient watering without over-saturating the soil.

Question 5.
How is optimal humidity maintained?
Answer:
We water plants regularly and use humidifiers if the air is too dry. Keeping water trays nearby also helps increase humidity around the plants.

Question 6.
Is there anything else that plants need for their healthy growth?
Answer:
Yes, plants need nutrients from the soil, good air circulation, and protection from pests. Regularly checking these factors helps them grow strong and healthy.

Question 7.
How do you prevent damage to plants from external factors, like pests, animals, or human activity (e.g., are there pathways between plant beds and protective fencing)?
Answer:
We create pathways between plant beds and use protective fencing. We also regularly inspect plants for pests and use natural repellents to keep them safe.

Question 8.
How are plants transported from the nursery to home gardens/farms?
Answer:
We carefully pack plants in boxes or pots to prevent damage. We ensure they are well-watered before transport and keep them shaded during the journey.

Note important information related to these plants in table 1.1 with the help of the expert.

Answer:

Activity 2 : Planning and laying out plant nursery (Page No. 12)

Question 1.
What is the available space for the nursery?
Answer:
The available space for the nursery should ideally be around 150 to 200 square feet. This area is enough to grow various plants while allowing space for pathways and access to water. If there is no land available, we can use pots or any unused space, like a parking lot or pathway, to create our nursery.

Question 2.
What factors were considered while choosing the particular location?
Answer:
While choosing the location for the nursery, we considered several important factors. First, the area should receive at least 2-3 hours of sunlight daily, which is essential for plant growth. Second, we need to avoid waterlogging, so the site should have good drainage. Lastly, it should be accessible for watering and maintenance.

Draw a layout or sketch of the nursery with dimensions (length, width). Show as many details as you can pathways, source of water, layout of beds, and so on.
Answer:

Activity 3 : Preparing land and setting up shade-net (Page No. 14)

Question 1.
What kind of shade-net or clothes did you use to provide shade to the plants?
Answer:
I used a green shade-net with a 50% shading percentage to protect the plants from too much sunlight. This helps keep them cool and healthy.

Question  2.
Which materials did you use to fix the shade-net (e.g., bamboo, wooden pole, mild steel pipe, etc.)?
Answer:
I used bamboo poles to fix the shadenet. They are strong and lightweight, making them perfect for supporting the net over the nursery area.

Activity 4 : Germinating seeds (Page No. 16)

Question 1.
Which seed did you use for conducting the seed germination test?
Answer:
I used tomato seeds for the germination test. Tomato seeds are easy to handle and grow quickly, making them perfect for learning about germination.

Question 2.
How many seeds were used for the germination test?
Answer:
I used 10 seeds for the germination test. Using a small number of seeds helps me observe how many will sprout and understand the germination rate better.

Question 3.
How many days did it take for the seeds to germinate?
Answer:
It took 7 days for the seeds to germinate. This is a typical time frame for tomato seeds, as they usually sprout within a week under the right conditions.

Question 4.
How many seeds germinated?
Answer:
Out of the 10 seeds, 8 seeds germinated. This means that most of the seeds were healthy and able to sprout, which is a good sign for planting.

Question 5.
What was the germination rate?
Answer:
The germination rate was 80%. I calculated this by dividing the number of seeds that germinated (8) by the total number of seeds (10) and multiplying by 100.

Germination Rate
\(=\left(\frac{\text { Number of germinated seeds }}{\text { Total seeds }}\right)\) x 100
=\(\left(\frac{8}{10}\right) \)x100=80

Activity 5 : Raising plants in the nursery (Page No. 18)

Method 1: Sowing seeds on raised-bed nursery

Question 1.
Which seeds did you sow in the raised-bed?
Answer:
In the raised-bed, I sowed tomato and cucumber seeds. These seeds are easy to grow and are great for beginners. They need warm weather and sunlight to thrive.

Question 2.
What have you done to provide optimal conditions for growth of seedlings?
Answer:
To help the seedlings grow well, I mixed small seeds with sand for even sowing. I kept the soil moist by watering gently and covered the seeds lightly with soil.

Method 2: Sowing seeds in plug or seedling trays

Question 1.
Which method did you use for sowing the seeds? (If you have used more than one method, please mention all of them.)
Answer:
In our plant nursery activity, I used two methods for sowing seeds. First, I sowed seeds in seedling trays filled with soaked cocopeat. This method is great for managing moisture and nutrients. Second, I also used raised beds, where I gently sowed seeds directly into the soil after mixing them with fine sand. Both methods help in growing healthy seedlings.

Question 2.
What steps have you taken to provide optimal conditions for the growth of seedlings?
Answer:
To ensure the seedlings grow well, I took several important steps. First, I soaked the cocopeat before filling the trays, which helps retain moisture. Second, I covered the trays with a tarpaulin sheet to keep them warm and humid for germination. After the seeds sprouted, I moved them to a shaded area to protect them from direct sunlight. Lastly, I watered them regularly to keep the soil moist but not soggy.

Method 3: Raising plants using stem cuttings

Question 1.
Which kind of plants did you use for plant propagation using cuttings? Did you use a cutting of hard, semi-hard or softwood?
Answer:
For plant propagation, I used cuttings from semi-hardwood plants like roses and guavas. These cuttings are partially mature and help the plants grow well.

Question 2.
What have you done to ensure conditions for growth?
Answer:
To ensure good growth conditions, I kept the cuttings in a warm, shaded area and watered them regularly. I also used cocopeat to maintain moisture and nutrients.
