Study Notes

Crop Variety Improvement

Crop variety improvement focuses on finding varieties with desirable characteristics for high yield
Breeding for disease resistance, fertilizer response, product quality, and high yields are key aspects
Hybridisation involves crossing genetically dissimilar plants, which can be intervarietal, interspecific, or intergeneric
Genetic modification introduces genes for desired characteristics, leading to genetically modified crops
New crop varieties must perform well in different environmental conditions for farmer acceptance
Quality seed is crucial for uniform germination and performance of a particular variety

Crop Production Improvement

Crop production depends on practices like irrigation, fertilization, and pest control
Most agriculture in India is rain-fed, making timely monsoons crucial for crop success.
Irrigation methods address water scarcity and ensure water availability during critical growth stages.
Canal systems distribute water from reservoirs or rivers
River lift systems draw water directly from rivers for supplementary irrigation
Tanks store run-off from smaller catchment areas
Rainwater harvesting and watershed management initiatives help increase water availability for agriculture

Cropping Patterns

Different cropping patterns can maximize benefits and resource utilization.
Mixed cropping involves growing two or more crops simultaneously on the same land for reduced risk and insurance against failure
Intercropping involves growing two or more crops in a specific pattern within the same field, maximizing nutrient utilization and pest control
Crop rotation involves switching crops over time, breaking pest and disease cycles and enhancing soil fertility
Weeds compete with crops for resources, necessitating their removal during early growth stages

Pest And Disease Control

Pests damage plants through root/stem/leaf cutting, sap sucking, or boring into stems/fruits
Plant diseases are caused by pathogens like bacteria, fungi, and viruses.
Proper storage conditions protect harvested crops from spoilage and pests
Suitable storage conditions include well-ventilated sheds, protected from rain, heat, and cold, with sloping floors for drainage
The floor of cattle sheds should be sloping for drainage and to facilitate cleaning.
Balanced rations containing appropriate nutrients are essential for maintaining healthy dairy animals
Feed additives containing micronutrients improve animal health and milk output.
Disease prevention is key to maintaining a healthy herd and increasing milk production
Healthy cattle show regular feeding habits and maintain a normal posture
Cattle diseases can be caused by internal and external parasites.
External parasites live on the skin and can cause skin irritations.
Internal parasites live within the body and can cause various health issues.
