🪤 The 5 Mistakes That Cost Marks

Not understanding the concept of crop rotation and its benefits

Not being able to calculate the increase ∈ crop yield due to fertilizers and irrigation systems
Not understanding the role of biotechnology ∈ crop production
Not being able to identify the advantages and disadvantages of different farming methods

✏️ 3 Solved PYQs

What is the ma∈ advantage of crop rotation? Answer: The ma∈ advantage of crop rotation is that it maintains soil fertility and reduces pests and diseases, increasing overall crop yield.
A farmer uses NPK fertilizer to increase crop yield. If the yield increases by 25%, what is the percentage increase ∈ yield per unit of fertilizer used? Answer: Let's assume the initial yield is 100 units. After using NPK fertilizer, the yield increases to 125 units. The percentage increase ∈ yield is 25%. To find the percentage increase ∈ yield per unit of fertilizer used, we need to know the amount of fertilizer used. Let's assume 10 units of fertilizer are used. The percentage increase ∈ yield per unit of fertilizer used is (25/10) × 100% = 250%.
A farmer uses drip irrigation to increase crop yield. If the yield increases by 30%, what is the percentage increase ∈ water savings? Answer: Let's assume the initial water usage is 100 units. After using drip irrigation, the water usage decreases to 70 units. The percentage decrease ∈ water usage is 30%. The percentage increase ∈ water savings is 30%.

🧠 The One Thing Most Students Get Wrong

Most students think that green revolution is a type of farming method, but it's actually a period of time when high-yielding varieties of crops were introduced, leading to a significant increase ∈ crop production.

👁️ Ayush's Note

To solve problems related to crop production, first identify the given information, such as the initial crop yield, the type of farming method used, and the amount of fertilizer or water used.
Then, use the formulas and concepts from the formula bank to calculate the increase ∈ crop yield or the percentage increase ∈ yield per unit of fertilizer used.
Finally, use the concepts from the formula bank to identify the advantages and disadvantages of different farming methods and to calculate the percentage increase ∈ water savings.
