Question

Explain any one method of crop production which ensures high yield.

Answer 1

Hint: The technique which promises and ensures the maximum yield of the crop is crop rotation. It is a practice of farming in which different kinds of plants are grown in a serial order based on their individual growing seasons.

Complete answer:
The branch of agriculture that studies the development and improvement of the crop with better efficiency for use of food and shelter is called crop production. Crop rotation is the exercise of growing different types of crops in a serial manner in the same area transversely an order of growing seasons. It reduces dependence on one set of nutrients, pest and weed burden, and the possibility of emerging resistant pests and weeds.

The underlying reason for practising crop rotation is, growing the same crop in the same place repeatedly for several years in a row progressively exhausts the soil of certain nutrients and chooses for an extremely modest pest and weed community. Without balancing nutrient use and expanding pest and weed communities, the efficiency of monocultures is highly reliant on external efforts. Contrariwise, well-designed crop rotation can diminish the necessity for synthetic fertilizers and herbicides by better using ecosystem amenities from a varied set of crops. Additionally, crop rotations can advance soil structure and organic matter, which lessens erosion and upsurges farm system flexibility.

A primary valuation of crop interrelatedness can be originated in how each crop:
a) Donates to soil organic matter (SOM) content.
b) Offers for pest management.
c) Achieves scarce or excess nutrients.
d) Interbreeds with other crops to yield hybrid offspring, and
e) It contributes to or manages soil erosion.

Note: A great advantage of crop rotation comes from the interrelationship of nitrogen-fixing crops with nitrogen-demanding crops. Legumes, like alfalfa and clover, collect available nitrogen from the atmosphere and store it in nodules in their root structure.
