Concept:Improve crop yieldsWhen plants of the same kind are cultivated in one place on a large scale. It is called a crop.Crop yields mean the production of the crop per unit area.More increase in crop yields means less manpower needed in the field.We can find or calculate crop yield by seed ratio.There are different kinds of factors present that improve crop yields.There are 3 types of improvement methods cultivation improvement, variety improvement, and protection improvement.Explanation:?Storage improvementThey must store the grains in airtight containers to protect them.Farmers store them in metal containers or jute sacks on a small or medium scale.Silos or granaries are preferred on a greater scale.This whole process is called 'storing'.Storing improvement does not help in the improvement of crop yield.Storage improvement is NOT a method to improve crop yields in India.Additional InformationCultivation improvementCultivation improvement is also known as product improvement.Farmers are able to make use of various farming practises and technologies because of the money or financial conditions.They include "no-cost" manufacturing procedures, "low cost" production practices, and "high cost" production practices. Verity improvementThe good seeds of crops can increase crop yield.By using disease resisting good high production quality seed, seeds that respond to fertilizer can increase it.Protection improvementThe field crops are infested with a significant number of insects, insect pests, and illnesses.If weeds and pests are not handled at the appropriate times, crops can be severely harmed, resulting in the loss of the majority of the yield.
