Long Answer Type Questions

Question 1.
Write about possibilities of profit and risk in the enterprise of seed production.
Answer:
The enterprise of certified seeds production is profitable. Such seeds have more selling price than the other seeds. But there is some initial cost involved e.g. cost of foundation seed, certification fees, cost to remove off-type plants, seed grading, packaging of seed, attaching tag, sealing and storing of seeds. During 2014-2015, minimum support price of one quintal of wheat was Rs. 1450. But certified seed of wheat was sold at a price of Rs. 2000-2500 per quintal. This way enterprise of seed production of certified and hybrid seed is very profitable.

There is also a fear of loss in this business also, as in other businesses. Some times the seed remains unsold and it can fail in laboratory test also. But the possibility of unsold seed is very less because already there is huge demand of seed in the market, which is not being fulfilled. So, this business is very profitable.

• seed germination
• physical purity of seed.
• a number of diseased seeds
• number of seeds of weeds in the seeds, seeds of other crops.
• moisture percent in the seed.
