APLIKASI PUPUK KANDANG SAPI DAN AIR LIMBAH LELE TERHADAP PERTUMBUHAN KELENGKENG (Dimocarpus longan L.) DI KEBUN BUAH AGROFORESTRI UNIVERSITAS LANCANG KUNING

Abstract

Longan (Dimocarpus Longan Lour) in the Unilak Agroforestry Orchard has the potential to be developed. The aim of this study was to analyze the effect of cow manure and catfish wastewater on the growth of longan. The study was conducted for 3 months, namely January-April 2022. The study design used factorial RAL with two factors, namely the dose of cow manure with 3 levels (control, 300 g, and 600 g) and catfish wastewater with 4 levels (control, 250 ml, 500 ml, and 750 ml). The variables measured were the increase in height, diameter, and width of the canopy. The results showed that giving a dose of 250 ml of catfish wastewater resulted in the greatest increase in height of 20.00 cm compared to 13.67 cm without giving catfish wastewater. Giving a dose of 300 gr cow manure resulted in the greatest height increase of 18.50 cm compared to 17.17 cm without cow manure. The control interaction of cow manure and catfish wastewater at a dose of 250 ml resulted in the greatest height increase of 23.67 cm compared to that without cow manure and catfish wastewater of 8.33 cm.
