Abstract

The decreasing area of agricultural land and declining water sources are forcing rice farmers to adopt various farming technology. Soil-less farming and alternate wetting-drying (AWD) irrigation can alternatively fix the problems (water substitutes soil as a proper growing media, while in AWD irrigation systems water can be saved), especially in the urban area. This study aimed to observe the growth of two rice varieties grown under soil-less media with AWD irrigation systems. The study was conducted in Sumberjeruk village, Jember city of Indonesia, from June-September 2021. A completely randomized design (CRD) within two factors and three replications was used in the experiment. The first factor was growing media, namely control (soil) + non AWD, water media + rice husk + non AWD, water media + non AWD, and water media + 1 day (once) AWD. The second factor was rice variety specifically Mapan 05 and Ciherang. The result showed that water media + rice husk gave the highest performance at plant height (73,88 cm), the number of the stem (35,25 stems), and the number of leaves (108,92 leaves). Moreover, there was a significant difference in stem diameter number between Mapan 05 and Ciherang (6,95 mm and 5,80 mm respectively).
