Maize (Makka) Farming Guide: Kharif and Rabi, Grain and Feed

Kharif maize is sown with the monsoon and relies mainly on rainfall, which means yield is more exposed to erratic rainfall, waterlogging risk in heavy downpours, and generally higher pest and disease pressure in the warm, humid conditions of the rainy season. Rabi maize is sown after the monsoon under assured irrigation, and generally benefits from more even moisture supply, cooler nights during grain fill (which favours better grain quality and often higher yield potential), and somewhat lower pest pressure — though it demands a reliable irrigation source, which not every farmer has.

Variety choice should reflect the season: many hybrids are bred and recommended specifically for kharif or specifically for rabi performance, so always check the seed packet or dealer recommendation for the season you're sowing rather than assuming one hybrid suits both equally well.

Maize yield responds very strongly to hybrid vigour, and using certified hybrid seed from a reliable source — rather than saved grain from a previous harvest — is one of the highest-return decisions in the whole crop, since hybrid vigour does not carry through reliably to the next generation of seed. Choose a hybrid suited to your season (kharif or rabi), your soil and rainfall/irrigation pattern, and, where fall armyworm is a known local problem, look for hybrids with better tolerance where these are available and recommended in your area.

A common recommendation for maize is roughly 60-75 cm between rows and 20-25 cm between plants, adjusted for the specific hybrid's growth habit and your target plant population — hybrid seed packets usually state a recommended plant population per acre or hectare, and hitting that target closely (not just approximately) matters more for maize than for many other cereals, since maize doesn't compensate for poor stands through tillering the way rice or wheat can.

Thin overcrowded stands early if germination comes in denser than intended, since maize plants compete hard with each other for light in a dense stand, at real cost to cob size and grain fill.

Fall armyworm is a relatively recent invasive pest in India (first reported in 2018) and has become one of the most serious threats to maize specifically, since it feeds deep inside the whorl of young plants where it's hard for sprays to reach. Look for the caterpillar's distinctive inverted-Y marking on its head, along with characteristic 'window-pane' feeding damage on leaves (thin, papery patches scraped through but not eaten all the way through) and visible frass packed into the whorl.

Scout the whorl of young maize plants weekly from early growth stages, since catching an infestation before the caterpillar burrows deep into the whorl is far more effective than trying to treat it afterward. Hand-picking caterpillars on small plots, encouraging natural predators, and applying targeted biopesticides early all help; avoid relying on any single chemical repeatedly, since fall armyworm develops resistance quickly. (See our full identification guide, Good Insects vs Bad Insects, for a photo and detailed description of this pest.)

Maize is a heavy nitrogen feeder with a fairly demanding fertilizer schedule: a basal dose of nitrogen, phosphorus, and potash at sowing, followed by top-dressed nitrogen split across two or three later applications — typically around knee-high growth stage and again around tasseling — rather than applying it all upfront. Splitting nitrogen this way matches the crop's actual uptake pattern and reduces both nutrient loss and the risk of excessive early vegetative growth at the expense of grain fill later.

Adjust the general schedule against an actual soil test where possible, particularly for phosphorus and potash, since requirements vary meaningfully with soil type and cropping history.

Maize serves two genuinely different end markets that are both worth understanding before you sow: food-grain maize, sold for direct human consumption and processing, and feed maize, which is the dominant raw material in poultry and animal feed formulations across India. Feed-grade maize demand has grown substantially alongside the growth of India's poultry industry, and in many regions the feed market is now a significant, steady buyer alongside the traditional food-grain trade — worth checking local mandi and feed-mill demand before deciding which variety and marketing channel to target.

Maize is ready to harvest when the husk has dried and turned papery brown and the kernels have hardened and reached physiological maturity (often visible as a black layer at the base of the kernel). Harvesting too early gives higher moisture grain that is harder to dry safely and more prone to mould; harvesting too late in wet conditions increases the risk of ear rot and pre-harvest sprouting.

Dry harvested maize down to around 12-14% moisture before storage or sale, since maize stored wetter than this is genuinely prone to aflatoxin-producing mould, which is a serious quality and safety concern for both food-grain and feed-grade maize.
