PENGARUH DOSIS PUPUK ORGANIK CAIR TERHADAP PERTUMBUHAN DAN PRODUKSI FODDER PADI (ORYZA SATIVA) HIDROPONIK

Abstract

Hydroponic rice fodder can be used as an alternative technology to produce forage to overcome the feed scarcity in the dry season and the lack of land used for animal feed. This research was aimed to determine the growth and production of rice fodder given with the addition of different doses of organic liquid fertilizer. This research was designed based on a completely randomized design (CRD) with 4 treatments. The treatments in this research were P0 = without adding organic liquid fertilizer, P1 = adding an organic liquid fertilizer dose of 30 g, P2 = adding an organic liquid fertilizer dose of 60 g, and P3 = adding an organic liquid fertilizer dose of 90 g. The variance test showed that different doses of organic liquid fertilizer showed no significant effect (P?0.05) toward the rice fodder height, the number of leaves, and fresh production of rice fodder. The average height of hydroponic rice fodder was (P0 = 10.46±0.34), (P1 = 11.33±1.60), (P2 = 10.45±0.50) and (P3 = 10.63 ±0.44). The number of hydroponic rice fodder leaves was (P0 = 200.75±44.81), (P1 = 194.00±21.76), (P2 = 211.00±42.64) and (P3 = 230.25±44 ,93). Fresh production of hydroponic rice fodder was (P0 = 332.25±3.59), (P1 = 340.50±7.93), (P2 = 337.00±11.43) and (P3 = 337.00±1 ,41). Based on the research results, it can be inferred that the addition of different doses of liquid organic fertilizer on hydroponic rice fodder planting has no significant effect on fodder height, the number of leaves, and fresh production of hydroponic rice fodder. This may be caused by several factors including uneven seed distribution, leaves formation that occurs at the age of 5-6 days of planting, and the nutrients contained in the planting media are not absorbed properly.
