Kern 112 F1 White Maize

Kern 112 is an F1 hybrid white maize for the Kharif season.

Land and sowing window

• Soil: well-drained sandy loam to silty loam. Maize does not tolerate standing water, so level the field and keep a drain at the lower end
• Sowing: April to June
• Best window: last week of May to end of June in Punjab (PAU); 25 June to 20 July under irrigation in Haryana (HAU). In fields that get waterlogged, sow by early June so the crop is established before the rains
• Rotation: fits maize–wheat, maize–potato and maize–berseem rotations; green manure or FYM before maize pays

How to sow

• Seed rate: 8 kg per acre is enough
• Spacing: 60 cm between rows × 20 cm between plants (about 33,000 plants per acre). On ridges, sow on the side of 60 cm ridges; on beds, 67.5 cm beds with 18 cm between plants
• Depth: 3–5 cm, in lines with a maize planter or seed-cum-fertiliser drill
• Thinning: if not planter-sown, thin to one plant every 20 cm at the first hoeing
• Pack size: 4 kg and 5 kg — two 4 kg packs cover one acre

Manure and fertiliser (per acre)

• FYM / green manure: green manure (dhaincha / sunhemp / cowpea) or well-rotted FYM before sowing. If 6 tonnes or more of FYM goes in every year, skip the basal P, K and zinc
• Nitrogen (N): 50 kg (about 110 kg urea) — one-third at sowing, one-third at knee-high stage, one-third just before tasseling
• Phosphorus (P₂O₅): 24 kg (about 55 kg DAP), all at sowing; reduce urea by 20 kg when DAP is used
• Potash (K₂O): 12 kg (20 kg MOP) at sowing, only where the soil test shows low potash
• Zinc: 10 kg zinc sulphate (21%) per acre at sowing where the last crop showed zinc deficiency (white bands beside the midrib of young leaves)

Water, weeds and pests

• Irrigation: 4–6 irrigations depending on rain. Never let the crop go dry at pre-tasseling, silking and grain filling. Drain out standing water within two days — young maize is killed by flooding
• Weeds: two hoeings at 15–30 days, or atrazine 50 WP within 10 days of sowing — 800 g per acre on medium to heavy soils, 500 g on light soils, in 200 litres of water (PAU)
• Fall armyworm (fauji keeda): scout the whorls from about 10 days after emergence and destroy egg masses. Spray only at threshold, directing the nozzle into the whorl — chlorantraniliprole 18.5 SC 0.4 mL or emamectin benzoate 5 SG 0.4 g per litre, as per label and state advisory
• Stem borer: attacks June–September. Pull out and destroy dead-heart plants at hoeing; Trichogramma cards at 10 and 17 days, or a recommended spray at 2–3 weeks if leaf injury is seen
• Diseases: keep the field well drained against bacterial stalk rot; remove crop residue against leaf blight

Harvest

• Stage: when the husk has dried and turned brown, even if the stalks and leaves are still somewhat green
• Shelling: dry the ears 3–4 days, shell at 15–20% grain moisture and market at about 15%
• Stover: the green part of the stalks can be fed to animals

Crop practices follow state agricultural university recommendations for North India; confirm doses for your district with your Kern dealer or KVK.
