KETAHANAN BEBERAPA VARIETAS PADI TERHADAP PENGGEREK BATANG PADA EKOSISTEM SAWAH MASUKAN BAHAN ORGANIK DAN ANORGANIK

This study aims that knowing the level of resistance several rice varieties to stem borer in organic and inorganic input paddy ecosystems. The research was conducted fields Nonong Village, Batui District, Banggai Regency, from March June 2020. used Split Plot Design method. main plot field ecosystem, namely fields, while subplots were 4 types varieties, namely: Ciherang, Cisantana, Ciliwung Towuti. Each treatment unit repeated three times order obtain 24 experimental units. results showed towuti variety planted ecosystem with more resistant borer. intensity attack population lowland matter higher than ecosystem. There is no interaction between ecosystems (input materials) on production
