Major Rice Pest Development after Increasing Rice Planting Index and Acceleration of Planting Time in Lampung Province

Abstract

Agriculture development in Indonesia has been targeted to attain food resilient by increasing rice production. Lampung has been involved in rice production increasing activity since 2008 up to now. Rice transplanted area in Lampung was increased by distinctive effort by mean of increasing rice planting index and acceleration of planting time to boost rice planting areas as well as production. The objectives of this study were to observe pest before and after; as well as ongoing rice field with and without increasing rice planting index and acceleration of planting time, and to analyze factors involved in the pest attack. The results showed that brown planthopper and rat were main pest problem. Infested area by brown planthopper and rat were negatively correlated with delayed planting but were increased by increasing planting index. The rise of brown planthopper populations was affected by pest management, planting system, integrated crop management implementation, and resistant variety planted. Meanwhile, the increase of rat attack was influenced by increasing of rice planting index, acceleration of planting time, and the dose of urea fertilizer. The brown planthopper and rat threaten sustainability of rice production in which increasing rice planting index and acceleration of planting time were implemented.
