The Effect of Catfish (Clarias Sp.) Wastewater LOF Concentration and Nitrogen Fertilizer Dosage on The Production of Ridge Gourd (Luffa acutangula L. Roxb)

Abstract

The ridge gourd is a horticultural product that has a pleasant, fresh flavor and health advantages. Due to limited consumption and production, there is no data on the production and harvest area of ridge gourd in institutions. Based on a market survey, the price of ridge gourds is quite profitable  for the development of ridge gourd. Therefore, this study aims to determine the main interaction effect of liquid organic fertilizer from catfish wastewater and N fertilizer on ridge gourd (Luffa acutangula L.Roxb) production. The study used a completely randomized factorial design consisting of two factors. The first factor was liquid organic fertilizer from catfish wastewater which consists of 4 levels: 0, 200, 400 and 600 ml/L per plant. While the second factor was N fertilizer consisting of 4 levels: 0, 20, 25, 30 g/plot. The parameters observed were flowering age, harvest age, number of flowers, number of fruits per plant, fruit weight per plant, fruit length per plant, number of remaining fruits per plant. Furthermore, the data were analyzed statistically and continued at the HSD test at the 5% level. The results showed that both the main factors and the interaction of liquid organic fertilizer from catfish wastewater and N fertilizer affected all observation parameters. The best treatment was found in the concentration 600 ml/L per plant of liquid organic fertilizer from catfish wastewater and 30 g/plot of N fertilizer.
