Maize
– The Versatile “Indian Corn”
Maize, also known as Indian Corn, is like that all-rounder in cricket—used for food, fodder, and even industrial purposes. In India, it is consumed by humans, fed to animals, and also used in industries for making starch, alcohol, and other products. In fact, in the USA, it’s primarily grown not for human food but to feed livestock—especially cattle (because beef is a major product there).
So, maize is both a food crop and a commercial crop.
🧪 Scientific Adaptability: Why Maize Thrives
Let’s understand it under conditions for growth:
1. Climate Requirement
- Maize is a kharif crop, which means it is generally grown in the monsoon season.
- It needs moderate warmth—temperature between 21°C and 27°C is ideal.
- However, the uniqueness of maize is that it is adaptable. It can grow in:
- Semi-arid regions (where rainfall is between 25 to 75 cm).
- But it cannot tolerate very high rainfall. Areas with over 100 cm rainfall are unsuitable.
- Hence, in very wet areas, maize fails, and crops like rice dominate.
🌦️ Special Case – Tamil Nadu:
In Tamil Nadu, due to the monsoonal reversal, the Northeast Monsoon brings rain in November and December. So, maize is sown in September–October, just before these rains begin. Here, it behaves like a rabi crop.
This shows how the timing of rainfall (not just the total amount) affects the sowing season.
2. Soil Requirement
- Maize is like a student who can study anywhere but performs best in a peaceful, clean environment.
- Similarly, maize can grow in many types of soil, but the highest yield is in:
- Old alluvial soil (well-drained, fertile)
- Loamy soils that are rich in nitrogen and free from coarse particles
Loamy soil = a perfect mix of sand, silt, and clay = excellent water retention + good drainage.
So, maize is soil-flexible but has its favorite conditions.
3. Cropping Pattern: Maize is a Team Player 😊
In India, maize is often grown alongside:
- Pulses,
- Oilseeds,
- Vegetables
This system is called inter-culture or mixed cropping, which is very common in subsistence agriculture where farmers aim for maximum utility of land.
Just like a shared flat where multiple people stay in harmony, maize often shares land with other crops!
📊 Production & Distribution
🌍 Global Scenario:
- USA is the world’s top producer—growing maize mainly to support the meat industry.
- China and Brazil follow.
🇮🇳 In India:
In terms of percentage production: Karnatka (15.52%)> MP (12.13%) > Bihar (11.50%) > Maharashtra (10.29%)
- There’s no single concentrated maize belt. Instead, it is scattered throughout the country.
- Grown almost everywhere except in the high rainfall eastern and north-eastern states, where water-loving crops like rice dominate.
- Interestingly, yield is highest in the southern states, like Andhra Pradesh and Tamil Nadu, and gradually decreases towards central India.
This is mostly due to better irrigation, soil conditions, and farm practices in the south.
🎯 Why is Maize Important?
- It is multi-utility: food, fodder, industrial uses.
- Highly adaptable to different regions and soils.
- Crucial for farmers in semi-arid zones where neither rice nor wheat performs well.
- Strategically important in food security and animal husbandry.
