PERTUMBUHAN DAN PRODUKSI TANAMAN SAWI (Brassica juncea L.) PADA BERBAGAI KOMPOSISI MEDIA TANAM DAN BOKASHI KOTORAN SAPI

Abstract

This study aims to determine the effect of the composition of growing media and cow dung bokashi on the growth and production of mustard greens. The research was carried out in the Greenhouse of the Faculty of Agriculture, Halu Oleo University, Kendari. This study used a Randomized Block Design (RAK) with two treatment factors and three replications. The first factor is the composition of the planting medium, consisting of 3 levels: soil (M0), a mixture of sand and soil in a ratio of 1:1 (M1), a mixture of sand and soil in a ratio of 2:1 (M2), and a mixture of sand and soil in a ratio of 1:2 (M3). The second factor was the dose of cow dung bokashi fertilizer, consisting of 3 levels, namely 0 t ha-1 (B1), 20 t ha-1 (B2) and 40 t ha-1 (B3). The results showed that the interaction between the composition of planting media and bokashi cow dung had a significant effect on height, number of leaves, leaf area, root weight, and plant crown weight. The treatment of planting media composition with a sand to soil ratio of 2:1 with the addition of 40 t ha-1 bokashi (M2B3) showed the highest growth and production of mustard plants.
