Explain any one method of crop production which ensures high yield.
Solution and Explanation
Inter cropping is a method used for a high yielding crop production. In this method, two or more crops are grown simultaneously on the same field in definite pattern. A few rows of one crop alternate with a few rows of second crop.
Example: soybean, maize or finger millet (bajara) and caw pea (labia).
The selected crops should have different nutrient requirements. This ensures maximum utilisatian of the nutrients supplied. It also prevents pests and diseases from spreading to all the plants belonging to one crop in a field. This method gives a better crop yield.

Strategies For Enhancement in Food Production
Animal Husbandry
The raising and breeding of livestock are known as animal husbandry. Dairy farm management and fisheries are also included under animal husbandry and responsible for the selection of good breeds for better yield, maintaining a well-ventilated house and proper cleanliness and hygiene, and regulating proper disposal of waste.

Animal Breeding
The practice of raising a group of animals belonging to a common species. Inbreeding and outbreeding are the two types of animal breeding.
- Animals of superior male and female breed are made to mate for 4 to 6 generations. According to Mendel's experiment, true-breeding species or pure lines are created by Inbreeding which results in homozygosity.
- The breeding involving animals that are not related is known as outbreeding.
- Bee-keeping: The rearing of bees for the production of honey and beeswax is known as apiculture. One of the most common species of the honey bee is Apis indica. Beeswax is used to prepare polish, cosmetics, etc.
- Fisheries: Cultivation or breeding of aquatic flora and fauna for a commercial purpose is known as aquaculture. Fish and fish products for consumption are known as pisciculture.
Plant Breeding
In order to get rid of nutrient deficiency diseases, crops need to have a specific nutrient value besides disease resistance, pest resistance, and high yield capacity. There are many strategies for enhancing food production through plant breeding.
- Somatic Hybrids
- Totipotency
- Biofortification

Single-Cell Protein
One of the ways to meet the growing demand of nutrients in plants and animals is a single-cell protein which is biomass that is rich in protein. microbes are produced on an industrial scale to get single-cell protein.
