Q1: What is agriculture?

Agriculture is the process of cultivating plants and raising livestock for food and other products. It involves soil preparation, sowing seeds, adding manure/fertilizers, irrigation, protection from pests, and harvesting crops at the right time.

Q2: Define tillage. Why is it necessary?

Tillage is the mechanical turning and loosening of soil. It is necessary to break up soil clods, aerate the soil, mix manure uniformly, remove weeds, and improve water retention. Well-tilled soil provides better conditions for seed germination and root growth.

Q3: What are the two main seasons for crop production in India?

Kharif (monsoon season: June-October) and Rabi (winter season: October-March). Kharif crops: rice, cotton, maize. Rabi crops: wheat, gram, mustard.

Q4: Distinguish between manure and fertilizer.

Manure is organic matter made from decomposed plant/animal waste, enriches soil structure and water-holding capacity. Fertilizer is chemically synthesized inorganic compound providing specific nutrients (N, P, K) in concentrated form, acts faster but can harm soil if overused.

Q5: What is crop rotation? State its benefits.

Crop rotation is growing different crops on the same land in successive seasons. Benefits: prevents nutrient depletion, breaks pest/disease cycles, reduces pesticide use, improves soil fertility, increases crop yield, and maintains ecological balance.

Q6: Name three methods of irrigation and explain drip irrigation.

Three methods: sprinkler, drip, and flood irrigation. Drip irrigation delivers water directly to plant roots through small perforated pipes. Benefits: saves 50% water, reduces weed growth, prevents soil erosion, and is ideal for hilly terrain and gardens.
