A number of insect pests are associated with maize in Indonesia. This article examines the species composition and status of maize pests in Donggala district of Central Sulawesi province in order to identify an appropriate control strategy and make location-specific integrated pest management recommendations. The study was carried out in seven villages in 2007, in which 50 samples were collected in each location from maize plots of 0.25-1 ha. Observations were recorded visually using sweep nets.
The paper examines the adoption of site-specific nutrient management (SSNM) by maize farmers in North Sumatra and its impact on production and farmers' income. The SSNM introduced to farmers was recommended by a study conducted in the region in 2004-2007: 160 kg ha-1 N, 72 kg ha-1 P2O5 and 90 kg ha-1 K2O. The study also disseminated a new high-yielding variety of maize together with recommendations for planting density and the number of seeds per hole. Research was carried out in five sites in Tigabinanga sub-district—a dryland farming region located 600-700m above mean sea level.
