Site Specific Nutrient Management for Maize on Ultisols Lampung
Lampung is the third major maize producing province in Indonesia after East Java and Central Java. In Lampungmaize is cultivated mainly in upland areas with ultisols and only some cultivated on paddy field as a secondary cropin the dry season. The average maize yield in Lampung is still 3.4 Mg ha-1...
