Technology for Maize Cultivation in Andhra Pradesh

Maize is mainly grown in Karimnagar, Warangal, Medak, Nizamabad, Adilabad and Randgareddy districts of Andhra Pradesh. This area forms the maize belt of this state. About 2.5 lakh hectares of maize is grown under rainfed situation in kharif season while around 0.6 lakh hectare is grown during Rabi under irrigated conditions. There is an immense scope for growing maize as an irrigated crop under Srirampadasagar and Nagarjunasagar projects and also in the non-traditional areas of the remaining districts of Andhra Pradesh.


Maize can be grown on a variety of soils ranging from sandy to clayey. But it performs best on well drained, aerated deep-loams and silt loams containing organic matter and nutrients. Maize may be raised on moderately acid soils, but the optimum PHrange is from 6.5 to 7.5. Highly saline, acidic, alkaline and water logged soils should be avoided. Deep ploughing twice, followed by leveling and making of ridges and furrows is required before sowing.


Experimental results have indicated that optimum time for sowing kharif crop is the fortnight before the onset of monsoon. This is possible in the situations where irrigation is available. In the absence of any irrigation facilities, sowing with the onset of monsoon will be ideal. Thus, in kharif the crop may be sown from the middle of June t middle of July. For Rabi maize, the most suitable date of sowing is between October 15 and November 15 in Telangana area and up to the first week of January in the coastal area.


Maintenance of optimum plant population is essential to realize higher yields. Experimental evidence obtained so far indicated that 66,000 plants/ha is the optimum, to obtain maximum yields. The optimum plant stand can be obtained if the planting distance is 75 cm between rows and 20 cm within rows. It is better to grow maize on ridges and furrows after the land is thoroughly prepared. The seed rate required is 20 kg/ha. Two to three seeds may be dibbled 2-3 cm deep on the right side of the ridge, at one-third distance from the top. The choice of optimum date of sowing is of greater importance in kharif as well as in Rabi seasons. Any marked delay in sowing is likely to result in lower yield. Also in late sown crops there is an increased incidence of leaf-blight and other pests and diseases. Excessive seedlings should be thinned 10 days after the emergence to have a single seedling per hill.

Weeding and Intercultivation

Pre-emergence spray of Atrazine (A trataf) at 1.5 kg/ha in case of light soils and 2.0 kg/ha in case of heavy soils mixed in 500-600 litres of water will control most of the broad leaf weeds effectively. When crop is 30-35 days old, intercultivation is done mainly for checking weed growth and for loosening the soil for proper aeration and conserving moisture. Under heavy weed infestation, manual weeding is necessary. Combination of intercultivation and use of weedicide in an integrated manner can be employed beneficially. During intercultivation a cultivator may be run followed by the ridger, for earthing up.


Farmyard manure or compost should be applied at the rate of 50 cartloads per hectare. The recommended dose of chemical fertilizer is 120 kg nitrogen and 60 kg phosphate for irrigated crops and 90 kg nitrogen and 45 kg phosphate per hectare for rainfed crop. Potash and zinc may be applied as per the soil test recommendations. All phosphate and all potash and zinc may be applied as a basal dose. Nitrogen may be applied in 3 splits in light soils one fourth at planting half at one month after sowing and the balance at the time of preflowering stage. Soils deficient in zinc, should receive 50 kg of zinc sulphate should not be mixed with phosphatic fertilizers. If zinc deficiency symptoms are observed in plants, 0.2 % zinc sulphate solution may be sprayed 2 or 3 times at weekly intervals.


Maize requires about 6-10 irrigations depending upon the maturity of a grown hybrid/variety. To get a good crop, irrigations should be given as and when required. Maize needs less irrigation till the crop attains a knee high state (30 to 40 days). As growth period advances the intervals between irrigation can be reduced and more quantity of water applied till the completion of milk stage. During the initial stages of crop growth, drainage is very important since waterlogged conditions impede the crop growth. Critical stages of water requirement in maize crop which restrict yield are tasselling, silking, and milk formation and dough stages. Maize sensitive to water stagnation at seedling stage and water stress at flowering, grain-filling and dough stages.

Plant Protection

Pests: The striped borer (Chilo partellus) infests the crop during kharif and the pink borer (Seasamia infers) during Rabi. These borers cause dead hearts in early stage of crop. Generally hybrids are tolerant to these pests. In endemicareas a prophylactic spraying of endosulfan 35 EC at 0.1 % is recommended when the crop is about 10-12 days old. If needed this may be followed by an application of carbofuran 3G granules in whorls at the rate of 7.5 kg/ha a fortnight after the first spray.

Diseases: The important diseases of maize are leaf blight (Helminthosporium turcicum), late wilt (Cephalosporium maydis) and charcoal rot (Macrophomina phaseolina). The use of recommended hybrids and varieties considerably reduces the incidence of these diseases. Therefore no chemical control measures are recommended. In case of seed production plots three sprayings of 0.3% dithane Z-78 (3 gms/litre) at weekly interval starting from knee high stage of the crop controls the leaf-blight.

Seed treatment with Capan followed by soil drenching with bleaching power (1,000ppm, Chlorine) at 45, 55 and 65 days as the age of the crop reduces the intensity of two kinds of stalk rots.


Harvesting is done when grain moisture reaches 20-25%. This can be noticed when the cobs-shealth (husk) dries up completely. After harvesting cobs should be dried in sunlight for about a week. The cobs are then ready for shelling. Hand-sheller, and powersheller driven by current or tractor are available and they can be used for shelling. After shelling, the grain can be dried for 2 to 3 days, cleaned and graded. The seed treatment with thiram@2gram per kilo of seed can be done and stored safely when seed moisture is about 8 to 10% . Storing in air tight containers reduces and other storage pests and diseases.
