- Kharif season lasts from June to October and requires warm, wet weather.
- Rabi season lasts from October to February and requires cooler, dry weather.
- Summer crops grow from February to May and require hot, dry weather.
- Millets like sorghum and pearl millet are drought-resistant and important for food security in dry regions.
- Pulses are vital for protein intake and crop rotation, improving soil nitrogen content.
- Oilseeds like groundnut and sunflower are used in cooking and industrial applications.
- Sugarcane is used for sugar production, with by-products like molasses and bagasse used in various industries.
- Cotton is an important fiber crop, with the lint used in textiles and seed for oil production.
- Rice is the staple food for a large portion of the global population.
- Groundnut is a major oilseed and source of edible oil, with both the seeds and haulm used in various applications.
- Tea and coffee are major export crops in India, with tea cultivated primarily in Assam and Darjeeling.
- Spices like turmeric, coriander, and chillies are cultivated extensively in India and used worldwide.
- Coconut is an important tropical crop, providing oil, fiber, and other by-products.
- Wheat is a major food crop, grown primarily during the Rabi season in India.
- Barley is grown for both food and fodder, especially in the temperate regions.
- Sugar beet is a cold-season crop, primarily grown in temperate climates for sugar extraction.
- Jute is a fiber crop used for making bags, ropes, and other industrial products.
- Lentils are a crucial source of protein in vegetarian diets, especially in India.
- Soybean is an important pulse and oilseed crop, widely grown in India for its high protein content.
- Fodder crops like Napier grass and alfalfa are important for livestock feed.
- Sesame seeds are rich in oil and are used in cooking and medicinal applications.
- Castor is grown for its oil, which is used in industrial applications, particularly in the aviation industry.
- Mustard oil is widely used for cooking and in the production of biodiesel.
- Black gram (Urad dal) is essential in Indian cuisine and crop rotation.
- Sunflower oil is popular for its health benefits due to its high unsaturated fat content.
- Coconut oil is used in cooking and various industrial applications, especially in cosmetics.
- Rapeseed and mustard are important oilseed crops in India and are also used in biodiesel production.
- Millets require less water and are drought-tolerant, making them ideal for arid regions.
- Sugarcane is mainly grown in tropical regions and requires large amounts of water.
- Soybean is high in protein and used extensively in both food and animal feed.
- Red soil is commonly found in semi-arid regions and supports crops like cassava and groundnut.
- Laterite soils are acidic and found in areas with high rainfall, supporting crops like tea, rubber, and cashew.
- Black soil is particularly suited for cotton cultivation due to its high moisture retention.
- Alluvial soils are the most fertile in India and support a wide range of crops including rice, wheat, and sugarcane.
- Saline soils have high salt content and require crops that are salt-tolerant, such as rice and sugarcane.
- Alkali soils are high in sodium and can be improved using gypsum.
- Acidic soils require liming to neutralize acidity and improve crop growth.
- Desert soils are low in fertility and require irrigation for successful crop cultivation.
- Forest soils are rich in organic matter and support diverse vegetation.
- Peaty soils are waterlogged and have high organic matter content but are not suitable for most crops.
- Alluvial soil is ideal for rice cultivation due to its high nutrient content.
- Lateritic soil has high iron and aluminum content and is suitable for crops like rubber and tea.
- Black soil supports crops that require moisture retention, such as cotton and soybean.
- Red soil is suitable for groundnut and other drought-resistant crops.
- Problem soils like saline and alkali soils need specific reclamation techniques to support crop growth.
