Potensi Abu Daun Bambu dan Kompos Jerami untuk Mengendalikan Wereng Coklat
This study aims to determine the effect of the bamboo ash and straw compost on brown planthopper and rice production. This research was conducted in Bakaran, Sukosari Village, Jumantono, Karanganyar in 12ndDecemberMarch 2017. The study was conducted using Complete Randomized Block Design (RCBD) in paddy fields consisting of 16 plots, each was 16 m2 with Bamboo Leaftreatment, Straw Compost, and Chemical Silica with SiO2of 200 kg 1ha dosage. The variables observed were: Population of brown planthopper, stem hardness, plant height, number of tillers, number of productive tillers, weight of 100 seeds, weight of filled seed, hollow seed weight and percentage of hollow seeds. The data obtained were analyzed by Analysis of Variance (ANOVA) and if there was a significant difference, it followed by Duncans Multiple Range Test (DMRT) at 5% level. The results showed that bamboo leaf ash and straw compost not significan increase the hardness of the rice plant stems and brown planthopper population. Straw compost has the highest potential compared to other treatments because it produces the hardest stem rice and the lowest brown planthoppers population at 11 Weeks. The application of silica from various sources has no direct role in rice production.
