The Influence of Conventional and Ratoon Planting System on the Presence of Main Pests Growth and Rice Production (Oryza sativa L.)

Abstract

Rice is an important commodity in Indonesia because it is the main food source consumed daily by people in Indonesia. Farmers often fail in cultivation of rice plant thereby affecting availability of foodstuffs. One factor of the rice production failure and the decreasing cultivation is the pests attack on the land plantation. Affecting factors of the pests existence is cropping system. This research was conducted to find out the presence of pest in ratoon and conventional cropping systems. Observations on this research used random sampling technique on the diagonal line with conventional and ratoon cropping systems. The variety used was Sertani 13 with planting distance 25 x 25 on 50 m x 20 m acres. The observation parameters are plant height, pest population, pest attack intensity, number of shoots and results of production. The data obtained will be analysed descriptively by comparing Conventional and Ratoon cropping systems. The results showed that conventional cropping systems and ratoon has good effect on pest growth and populations however both system have bad effect on rice production.
