SERAPAN HARA MAKRO PRIMER PADA BEBERAPA VARIETAS PADI LOKAL DENGAN PENGAIRAN SRI DAN KONVENSIONAL PADA MUSIM TANAM YANG BERBEDA

The aim of the study entitled "Primary Macro Nutrient Uptake in Several Local Rice
Varieties with SRI and Conventional Irrigation in 2 Planting Seasons" is to study various
varieties, irrigation and planting seasons in primary macro nutrient uptake. In addition to
knowing its effects, this study also aims to determine the interactions between varieties,
irrigation and the growing season in primary macro nutrient uptake. The research was
carried out in the Experimental Land, Soil and Plant Nutrition Laboratory, and Production
Laboratory II of the Faculty of Agriculture, University of Muhammadiyah Yogyakarta in
August to December 2020 and March to July 2019
The study was conducted with the field trial method, this study used a research
method that was conducted by designing factorial plot research plot within 3x2 arranged in
a Complete Randomized Block Design. The first factor is national superior rice varieties and
local varieties adding Rojolele early (VRL), Pandan fragrant (PW), Mentic fragrant (MW)
varieties. The second factor is the type of irrigation which consists of 2 types of irrigation,
namely conventional (A1) and 10 days of watering inundation and 5 days of dry (A2) spring
factors such as the rainy season (M1) and the dry season (M2)
The results showed several variations that affect the weight of the 8th week and the
absorption of N. The early varieties of Rojolele provide N uptake, the type of irrigation affects
the dry weight of rice plants in the 13th week, P uptake, and K absorption, kinds of dry season
dry weight of unhusked rice, dry season yields the highest yield, Interaction between varieties
and irrigation occurs in the parameters of dry weight of the harvested rice varieties Rojolele
early, with SRI irrigation in the Dry season
