Abstract

An experiment was conducted at IAAS Paklihawa, Bhairahawa from 6th October 2018 to 15th November 2018 (40 days). An open barrel Aquaponics system with a double factor RCBD type experimental design was used consisting of 3 replications and 2 factors under study. The two factors were boron concentrations (1%, 2% and 3%) and BLM varieties (Marfa Chauda Paat, Manakamana and chinese-430). Marfa Chauda Paat (47.35 gm.) was the highest yielding variety followed by Manakamana (36.42 gm.) and Chinese-430 (26.82 gm.). 1% Boron was found to be the most suitable concentration among the test concentrations for leaf yield. A maximum weight gain of the fish was observed in tank 3 (96.44%) followed by tank 1 (86.26%) and tank 2 (82.18%). An excellent survival percentage of fish was observed as 88.89%, 95.56% and 91.11% in tank 1, 2 and 3 respectively. Similarly, the Average Daily Growth Rate (ADGR) was recorded to be 126.5mg, 91.5mg and 128.25mg in tank 1, 2 and 3 respectively. The Specific Growth Rate (SGR %) was obtained to be 1.26, 1.38 and 1.46 for tank 1, 2 and 3 respectively. Furthermore, final harvest weight of fish was obtained to be 437g, 349.21g and 428.2g in tanks 1, 2 and 3 respectively.
