SERAPAN HARA MAKRO PRIMER BERBAGAI VARIETAS UNGGUL PADI DENGAN PENGAIRAN KONVENSIONAL DAN BERSELANG
Abstract
An aims of research “Primary Macro Nutrient Absorption of Superior Paddy Varieties with Conventional Irrigation and Intermittent Irrigation” to know the influence of varieties and irrigation on primary macro nutrient absorption. Beside that, this research to know correlation between variety and irrigation on primary macro nutrient absorption. The research has been done in experimental farm, soil laboratory, and second production laboratory of agriculture faculty, Universitas Muhammadiyah Yogyakarta on August 2018 until December 2018.
The research was done by farm experimental method, used experimental design on Randomized Completely Block Design (RCBD). The first factor was varieties consist of Inpari 33, Ciherang, Rojolele, Memberamo. The second factor was irrigation consist of intermittent irrigation and conventional irrigation.
The result of research showed that variety significantly effect on dry stover on eighth week and N absorption. The both parameter has correlation if N absorption more high then dry stover on eighth week high too. Memberamo showed highest dry stover on eighth week and N absorption than the other varieties. Irrigation significantly effects on dry stover on thirteenth week, P absorption, and K absorption. Conventional irrigation method showed dry stover on thirteenth week higher than intermittent irrigation method. There was correlation between variety and irrigation on on dry stover on eighth week and N absorption parameter. Both parameters showed that Memberamo with conventional irrigation gave highest N absorption and dry stover on eighth week than the other combination of variety and irrigation.
