Question

explain any one method of crop production which ensures high yield

Answer 1

Crop rotationis one of the methods of crop production that ensures high yield. It is the method of growing two or more varieties of crops on the same land in sequential seasons. A crop utilises some particular nutrients in larger quantities from the soil. Then, if the same crop is grown in subsequent seasons those nutrients will get depleted in the soil. Therefore, crops having different nutrient requirements are rotated. For example, legumes which have nitrogen-fixing bacteria in their root nodules supply the soil with nitrogen. Therefore, these legumes are rotated with nitrogen requiring cereals such as wheat and maize. This method reduces the need of fertilizers, thereby increasing the overall yield of crops.

Answer 2

Answer♡

Hybridization is one method through which we can produce the crop and which ensures high yield.

Steps involved in hybridization:

• Selection of parent plants with desired qualities.

• Removal of stamens from the male flower.

• Collection of pollen grains from the male flower.

• Pollinating the female flower using the collected pollen grains.

• Covering the mother plant with polythene bag.

• Collection of mature seeds from the mother plant.

• Selecting and growing better varieties of offsprings.
