Three distinct groups i.e. Pish, Valencia and Virginia are popular varieties. A seed rate of 110 to 150 kg/ha is required. The spacing of the groundnut is 30 x10 cm or 30x15cm.

As the crop is a closely spaced crop, sprinkler irrigation is ideal for irrigating maize. The recommended models of sprinklers are M110ST & RAYNTM normally spaced at 12m x 12m or M150ST sprinklers spaced at 18m x 18m.
The sprinkler application rates should not exceed the safe intake rate of the soil to avoid run-off and wastage of water. Refer to the table below for basic intake rates of soils:
|S No.||Soil Type||Good Soils with
High Organic Content
|Poor Soils with
Low Organic Content
|1.||Coarse sand||20 - 25 mm/hr||12.5 mm/hr|
|2.||Fine sand||12.5 - 20 mm/hr||9.00 mm/hr|
|3.||Fine sandy loams||12.50 mm/hr||7.50 mm/h|
|4.||Silt loams||10.00 mm/hr||6.85 mm/hr|
|5.||Clay loams||7.50 mm/hr||6.35 mm/hr|
The fertilizer requirement for maize in kg/ha is as under:
Kc = Crop co-efficient.
ETo = Reference evapo-transpiration (mm)
ETm = Maximum evapo-transpiration = Kc x ETo (mm)
ETa = Evapo-transpiration actual (mm)
Ya = Actual yield
Ym = Maximum yield
