Human and Economic Geography: UPSC Previous Year Questions (Geography)

Explanation

Mixed farming is an agricultural system where crop cultivation and livestock rearing are carried out on the same farm. Mixed farming integrates crop production and animal husbandry, balancing risks while recycling nutrients through manure and crop residues. It diversifies income and enhances sustainability. This practice is designed to maximize the use of available resources and diversify the income sources for the farmer. The integration of crops and animals is a key feature that distinguishes mixed farming from other farming systems.

Option (a) is incorrect: It involves crop diversification typical of commercial farming, not mixed farming with livestock.

Option (b) is incorrect: describes intercropping, which lacks the animal component essential to mixed farming.

Explanation

The crops which are predominantly rainfed in India are Groundnut, Sesamum and Pearl millets. Groundnut is a drought-tolerant crop that requires moderate rainfall for its growth and development. Rainfall for cultivation - 500 to 600 mm per annum, distributed rainfall pattern throughout the growing season. Groundnut can withstand a dry spell of 15-20 days during its vegetative stage, but it requires adequate moisture during the flowering and pod formation stages. Sesamum requires temperature is 25°C to 30°C, can tolerate up to 40°C, sensitive to frost required rainfall is 500-600 mm, its drought-tolerant, excessive rainfall during flowering can cause lower yields. It requires well-drained Soil type, rich in organic matter, pH range of 5.5 to 8.0. Pearl millet is a hardy crop that can grow in semi-arid regions. The ideal rainfall for pearl millet cultivation is between 400 to 600 mm per annum, with a well-distributed rainfall pattern throughout the growing season. Pearl millet can tolerate drought conditions and requires moisture during the early growth stages, especially during germination and tillering. Rainfed agriculture is carried out in a wide range of soil types, agro-climatic conditions, and annual rainfall ranges from 400 mm to 1600 mm. Rainfed areas account for percent of millet production, 88 percent of pulses, 73 percent of cotton, 69 percent of oilseeds including groundnut and Sesame.
