Study Notes
Crop Production and Management
- India has diverse climatic conditions and a wide variety of crops grown in different regions.
- Two broad cropping patterns are kharif (rainy season, June to September) and rabi (winter season, October to March).
- Kharif crops include paddy, maize, soyabean, groundnut, and cotton.
- Rabi crops include wheat, gram, pea, mustard, and linseed.
Basic Practices of Crop Production
- Preparation of Soil: First step in crop production, loosening and turning the soil to allow roots to penetrate deep.
- Plough: Used for tilling, adding fertilizers, removing weeds, and turning the soil.
- Manure and Fertilizers: Adding organic matter (manure) improves soil texture, water-holding capacity, and replenishes nutrients. Fertilizers are chemical nutrients that can lead to soil depletion and water pollution if overused.
- Irrigation: Providing water to crops, especially during dry seasons.
- Traditional Irrigation Methods: Moat (pulley-system), Chain Pump, Dhekli, and Rahat (lever system).
-
Modern Irrigation Methods:
- Sprinkler System: More useful for uneven land where water is scarce, uses rotating nozzles to sprinkle water.
- Drip System: Water falls drop by drop directly near roots, minimizing water waste, suitable for gardens and fruit trees.
Protection from Weeds
- Weeds: Unwanted plants that compete with crops for resources like water, sunlight, and nutrients.
-
Methods of Weed Control:
- Manual Removal: Pulling out weeds by hand.
- Herbicides: Chemical substances used to kill weeds.
Harvesting
- Harvesting: The process of gathering mature crops from the field.
- Threshing: Separating the grain from the chaff (straw).
- Winnowing: Separating light chaff from heavier grains using wind.
Storage
- Storage: Properly storing harvested crops to prevent spoilage and insect infestation.
- Drying: Reducing moisture content in grains to inhibit the growth of pests and organisms.
- Neem Leaves: Used for storage as a natural pest-repellent.
Food from Animals
- Animals provide us with food, milk, meat, eggs, and other products.
