Abstract

This study aimed to determine the effect of biourin on the growth and yield of sweet corn (Zea mays Saccharata Sturt). This research was conducted at the Bengkulu Agricultural Instrument Standards Implementation Center (BPSIP). This research was carried out using a Completely Randomized Design (CRD), with four treatments of biourin liquid organic fertilizer. P0: Control (NPK fertilizer), P1: 50 ml/l water, P2: 100 ml/l water, P3: 150 ml/l water each treatment was repeated seven times.  The results of this study showed that the provision of goat biourin had no significant effect on the parameters of plant height (14 and 28 hst), the number of leaves (14, 28, and 42 hst), stem diameter (14, 28 and 42 hst), cob length, cob length without cob, the diameter of the cob with weighed cob, the diameter of the cob without weighed cob, crown wet weight, crown dry weight, root wet weight, root dry weight and which significantly influenced the parameters of plant height (42 hst), weight of the cob with weighed cob, and weight of the cob without weighed cob.

Abstract

The use of natural growth regulators offers a sustainable alternative to synthetic compounds in hydroponic systems. This study evaluates the effect of natural plant growth regulators (PGRs) from coconut water and bamboo shoot extract on the growth of green lettuce (Lactuca sativa L.) in a Deep Flow Technique (DFT) hydroponic system and determines the optimal concentration. The experiment, conducted at BPSIP from October to November 2024, used a Completely Randomized Design (CRD) with nine treatments: a control, coconut water, and bamboo shoot extracts at concentrations of 10, 20, 30, and 40 ml L?¹, with three replications. The results showed that PGR applications did not significantly affect most parameters, including plant height at 21 and 35 days after transplanting (DAT), leaf dimensions, fresh shoot weight, and root weight. However, significant effects were observed on plant height at 28 DAT and leaf number at 28 and 35 DAT. Coconut water at 10 ml L?¹ produced the best response for these parameters. These findings confirm that the effectiveness of natural PGRs in DFT hydroponics is concentration-dependent and that under optimal nutrient conditions, their addition does not consistently enhance lettuce growth.
