Question

In seed drill, the area is covered by one revolution is 10 $m^{2}$, seed drop in one revolution is 40 grams, then what is the seed rate}

• A. $40~kg/ha$
• B. $30~kg/ha$
• C. $20~kg/ha$
• D. $10~kg/ha$

Hint:

Multiply your "Grams per 10 $m^{2}$" by 1 to get "Kilograms per hectare." It's a quick conversion shortcut.

Answer 1

The Correct Option is A

Step 1: Concept
Seed rate is the amount of seed sown per unit area, typically expressed in kg per hectare (ha).

Step 2: Meaning
1 hectare = 10,000 $m^{2}$. We need to scale the sample measurement to this standard area.

Step 3: Analysis
Area = 10 $m^{2}$; Seed = 40 g. For 1 $m^{2}$, seed = 4 g. For 10,000 $m^{2}$ (1 ha), seed = 40,000 g.

Step 4: Conclusion
40,000 g = $40~kg$. Thus, the rate is $40~kg/ha$.
Final Answer: (A)
