Improvement in Food Resources
Main Concepts
Crop Production- It contains improving yield and quantity. Improving
yield means if we get 20quintal rice from 1 acre land so when we
improve it we get increased amount of rice from that same 1 acre land.
Animal Husbandry- It contains cattle(cows, buffaloes), poultry(hen),
fisheries.
Need- The need of crops in increasing due to the increase in the
population of the world.
10 Key Facts
Crop varieties: Hybrid (high yield) + Improved (disease
resistant)
Nutrient management: Manure (organic) vs Fertilizers
(chemical)
Irrigation: Drip, sprinkler (water saving)
Cropping patterns: Mixed, Intercrop, Crop rotation
Pest control: Weedicides, Pesticides, Bio-agents
Storage: Silos, Granaries (prevent spoilage)
Cattle breeds: Indigenous (Sahiwal) vs Exotic (Jersey)
Poultry: Broiler (meat) vs Layer (eggs)
Fish farming: Marine + Inland + Aquaculture
Bee-keeping: Honey + Wax (Apiculture)
