The correct answer is D. All of the above.
The Bhoochetana program in Karnataka promotes integrated nutrient management, soil and water conservation, and pest and disease management.
Integrated nutrient management is a holistic approach to plant nutrition that takes into account the needs of the plant, the soil, and the environment. It involves using a combination of organic and inorganic fertilizers, as well as other methods such as crop rotation and cover cropping, to ensure that plants have the nutrients they need to grow healthy and productive.
Soil and water conservation are essential for sustainable agriculture. Soil conservation practices such as terracing, contour farming, and mulching help to prevent soil erosion and improve water infiltration. Water conservation practices such as drip irrigation and rainwater harvesting help to reduce water use and improve water efficiency.
Pest and disease management is essential for protecting crops from damage. Pest management practices such as crop rotation, resistant varieties, and biological control help to reduce the use of pesticides. Disease management practices such as sanitation, crop rotation, and resistant varieties help to reduce the incidence of plant diseases.
The Bhoochetana program is a successful example of how integrated agricultural practices can improve crop yields, reduce environmental impacts, and increase farmer incomes.
