Cauliflower (Brassica oleracea var. botrytis L.) is a vegetable belonging to the cruciferous family. This plant has high economic value and stable market demand. The purpose of this study was to determine the effect and determine the dosage of liquid organic fertilizer (POC) from bamboo shoots on pests and the growth of cauliflower (Brassica oleracea var. botrytis L.).
The research method used was a randomized block design (RAK) with 6 treatments and 4 replications. The treatments were as follows P0 = 0 ml/L of water (without treatment), P1 = 4 grams/L of NPK water , P2 = 50 ml/L of bamboo shoot POC water , P3 = 100 ml/L of bamboo shoot POC water, P4=150 ml/L of bamboo shoot POC water, P5 = 200 ml/L of bamboo shoot POC water. This research was conducted in October – December 2024 The experimental location was at Dsn. Banyuurip Rt 01/ Rw 01, Ds. Mundusewu, Kec Bareng, Kab. Jombang, East Java with an altitude of ± 500 mdpl. The parameters observed included plant height, number of leaves, plant wet weight, plant flower weight, mass weight per unit. The data analysis used was ANOVA (Analysis of Variance) with the Honestly Significant Difference (HSD) test at a level of 5 %.
The results of this study indicate that the treatment of liquid organic fertilizer from bamboo shoots significantly affects the growth and yield of cauliflower (Brassica oleracea var. botrytis L.). The optimal dose is between 150-200 ml/L on the parameters of plant height, number of leaves, flower weight, wet weight and flower mass weight per plant for cauliflower plants.
