Answer:
In agriculture , crop yield (also know as "agricultural output") refers to the both the measures of the yield of a crop per unit are of a land cultivation and the seed generation of the plant itself ( example if three grains are harvested for each grain seeded,the result yield is 1:3.
There are three basic approaches that are adopted in our country to increase the yield from agricultural fields. They are:
Crop variety improvement
Crop production management
Nutrient management
Crop variety improvement:
Varietal improvement means combining desirable characteristics in one and multiplying it. Plant breeders select plant varieties with desired character and cross them. The developed offsprings combine the qualities of both plants. These varieties are multiplied and supplied to farmers.
Crop production management:
India is an agriculture based country. Three fourth of the population engaged in agriculture.
Farmer’s purchasing capacity for inputs decides the cropping system and production practices. These include ‘no cost’ production, ‘low cost’ production and ‘high cost’ production practices.
Nutrient management:
Like other living organisms, plants also require inorganic elements for building their structure and maintaining their metabolic process. These inorganic elements are called nutrient. There are sixteen nutrients which are essential for plants. Nutrients are supplied to plants by air, water and soil.
Macronutrients: The essential elements, which are utilized by plants relatively in large quantities, are called macronutrients.
Micronutrients: The essential elements, which are used by plants in small quantities, are called micronutrients.
