Study Notes
Crop Improvement Factors
- Weather conditions, soil quality, and water availability affect crop yield and cultivation practices.
- Developing crop varieties that can thrive in diverse climatic conditions is essential.
- Varieties tolerant to high soil salinity have been developed.
Objectives of Variety Improvement
- Increase crop yield per acre to improve productivity.
- Enhance quality considerations, such as baking quality in wheat, protein quality in pulses, and oil quality in oilseeds.
- Develop resistance to biotic stresses (diseases, insects, nematodes) and abiotic stresses (drought, salinity, water logging, heat, cold, and frost).
- Reduce maturity duration to increase the number of crop cycles per year and minimize production costs.
- Promote uniform maturity for efficient harvesting and reduced losses.
Desirable Agronomic Characteristics
- Wider adaptability to stabilize crop production under different environmental conditions.
- Tallness and profuse branching are desirable for fodder crops.
- Dwarfness is desired in cereals to reduce nutrient consumption and increase productivity.
Crop Production Management
- Farming practices vary depending on land ownership, financial conditions, and access to information and technologies.
- Financial conditions influence farmers' choices of farming practices and agricultural technologies.
