Factors affecting crop production, climatic, edaphic, biotic, physiographic, and socio-economic factors MCQ for ICAR-JRF/SRF, ICAR-UG, NET, IBPS-AFO, CUET-PG, AAO, FCI, IFFCO, FSO, JET, State exams, Agriculture Supervisor and other agriculture competitive exams.

Crop production can be affected by a variety of internal and external factors, including:

Climatic factors: such as precipitation, temperature, atmospheric humidity, solar radiation, wind velocity and atmospheric gases.
Edaphic factors: soil-related factors such as soil pH, fertility, texture, and drainage.
Biotic factors: pests and diseases that can cause significant damage to crops.
Physiographic factors: physical characteristics of the land such as slope, elevation, and aspect.
Socio-economic factors: such as market prices, government policies, labour availability, and technology.
These factors are important for exams like ICAR-JRF/SRF, ICAR-UG, NET, IBPS-AFO, CUET-PG, AAO, FCI, IFFCO, FSO, JET, State exams, Agriculture Supervisor and other agriculture competitive exams.
