Plant Nutrition

The video discusses nutrient deficiencies in plants, highlighting the importance of micronutrients like nitrogen, magnesium, potassium, and phosphorus for plant growth. It explains how deficiencies affect plant health and growth, leading to symptoms like yellow leaves and stunted growth. The video also covers agricultural practices for managing nutrients, such as hydroponics, crop rotation, and the use of fertilizers, emphasizing the significance of nutrient availability for optimal crop yield.

What is the primary role of nitrogen in plant growth?

• To make chlorophyll

• To increase photosynthesis rate

• To produce protein

• To enhance root absorption

Why does a magnesium deficiency cause yellowing in plants?

• It causes nutrient leaching

• It reduces chlorophyll production

• It limits root growth

• It affects the plant's immune system

What symptom is associated with a potassium deficiency in plants?

• Falling leaves

• Purple veins

• Yellow leaves with green veins

• Dark green leaves

How does phosphorus deficiency affect plant growth?

• It causes yellowing of leaves

• It stunts growth and affects energy transfer

• It increases fruit production

• It enhances root development

What is a key advantage of hydroponics over traditional farming?

• It requires less water

• It allows better control over nutrient supply

• It is cheaper to set up

• It uses natural fertilizers
