Zea mays
Sunlight
Full sun — requires maximum light for optimal yield. Does not tolerate shade.
Water
500-800 mm per crop. Critical water demand period is tasseling through early grain fill (VT-R2). Drought at silking causes severe yield loss.
Soil
Deep, well-drained loam or sandy loam. pH 5.5-7.0. High organic matter beneficial. Avoid waterlogged soils.
Temperature
Optimal 25-33°C. Growth stops below 10°C. Pollination fails above 38°C.
Humidity
Moderate. High humidity during grain fill promotes ear rots and mycotoxin contamination.
Season
Warm season — 80-140 days depending on variety. Plant after soil temperatures exceed 12°C.

Overview
Maize is the world's most produced grain by tonnage and a staple food for hundreds of millions of people in sub-Saharan Africa, Central America, and parts of South America. It is used as food (maize flour, ugali, tortillas, posho), animal feed, and industrial feedstock (ethanol, starch). In Africa, maize is the most important cereal crop, providing 30-50% of calories in eastern and southern Africa. The crop is remarkably adaptable, growing from sea level to 3,000 m elevation and in rainfall zones from 400-2,500 mm. Major producers include the United States, China, Brazil, Argentina, and Mexico. Maize is a C4 plant with high photosynthetic efficiency, making it one of the most productive crops per unit of water and land.
Plant Health
Maize (Corn) is susceptible to 4 known diseases. Early detection is critical — use the CuraPlant app to scan leaves and get an instant AI diagnosis.
मक्का का घातक परिगलन रोग
मक्का का घातक परिगलन MCMV और SCMV विषाणुओं के संयुक्त संक्रमण से होता है। पत्तियों पर मॉटलिंग से लेकर पूरे पौधे की मृत्यु तक लक्षण दिखते हैं। प्रमाणित बीज, कीट नियंत्रण और फसल चक्र से रोकथाम करें। संक्रमित पौधों को नष्ट करें।
मक्का स्ट्रीक विषाणु रोग
मक्का स्ट्रीक विषाणु लीफ़हॉपर कीट द्वारा फैलता है। पत्तियों पर शिराओं के समानांतर पीली धारियाँ बनती हैं। पौधे बौने रह जाते हैं। MSV प्रतिरोधी किस्में, लीफ़हॉपर नियंत्रण और समय पर बुवाई से रोकथाम करें।
मक्का का ग्रे लीफ़ स्पॉट
मक्का का ग्रे लीफ़ स्पॉट सर्कोस्पोरा ज़ीएमैडिस से होता है। पत्तियों पर लंबे, आयताकार, भूरे धब्बे शिराओं के समानांतर बनते हैं। फसल चक्र, प्रतिरोधी किस्में और फफूंदनाशकों से प्रबंधन करें।
मृदुरोमिल आसिता (डाउनी मिल्ड्यू)
मृदुरोमिल आसिता ऊमाइसीट प्रजातियों से होती है। पत्तियों पर पीले धब्बे और नीचे भूरी-बैंगनी फफूंद बनती है। मैंकोजेब, मेटालैक्सिल या कॉपर फफूंदनाशक से प्रबंधन करें। हवा संचार और ड्रिप सिंचाई से रोकथाम करें।
Cultivation Guide
Plant at 75 × 25 cm spacing for optimal plant population (53,000 plants/ha)
Apply nitrogen in 2 splits: at planting and at knee height (V6)
Control weeds early — maize is most sensitive to competition in first 6 weeks
Scout for fall armyworm weekly from emergence through tasseling
Harvest when grain moisture is below 20% for safe storage
Store grain at <13% moisture to prevent aflatoxin and weevil damage
Companion Planting
Strategic companion planting reduces pest pressure, improves pollination, and can significantly increase yields.

Common Questions
Maize (Corn) grows best during the warm season — 80-140 days depending on variety. plant after soil temperatures exceed 12°c.. It requires optimal 25-33°c. growth stops below 10°c. pollination fails above 38°c. and full sun — requires maximum light for optimal yield. does not tolerate shade.. In tropical regions with consistent warmth, it can often be grown year-round with proper irrigation.
Maize (Corn) is commonly affected by Maize Lethal Necrosis, Maize Streak Virus, Maize Gray Leaf Spot and 1 others. Regular crop monitoring, good air circulation, avoiding overhead irrigation, and using disease-resistant varieties are the most effective prevention strategies.
Maize (Corn) grows best in deep, well-drained loam or sandy loam. ph 5.5-7.0. high organic matter beneficial. avoid waterlogged soils.. For irrigation: 500-800 mm per crop. critical water demand period is tasseling through early grain fill (vt-r2). drought at silking causes severe yield loss.. Maintaining proper soil moisture without waterlogging is critical — Maize (Corn) is sensitive to both drought stress and root rot from excess water.
Maize (Corn) grows well alongside bean, squash, groundnut. These companions help repel pests, improve pollination, or provide ground cover. Avoid planting near tomato, which can inhibit growth or share susceptibility to the same pests and diseases.
