Abstract

The fluctuating and decreasing production of shallots impacts the national stock. Its cultivation using high inorganic fertilizers requires high costs, reduces soil fertility, and affects long-term production.  Efforts are needed to increase production at a lower cost, reduce the use of inorganic fertilizers, and be more environmentally friendly.  One of them is using eco-enzymes that can be used as fertilizers, soil conditioners, and as a source of plant nutrients.  This study aims to evaluate and analyze the effectiveness and potential of eco-enzymes to increase the growth and production of shallots, while reducing the amount of inorganic fertilizer.  The study used a Randomized Block Design, four replications. There were three levels of treatment: P1 eco-enzyme; P2 eco-enzyme + N, P, K fertilizer 50%; P3 N, P, K fertilizer 100%. Each treatment consisted of 8 experimental units, for a total of 96, with a dose of N= 150 kg urea.ha-1, P= 200 kg SP-36.ha-1 and K= 150 kg KCl.ha-1. Eco-enzyme was given every week with a concentration of 1 ml.l-1; half was given by spraying the plants and half by watering the media.  The results showed that eco-enzyme is effective and can potentially increase the growth and production of shallots and reduce the use of inorganic fertilizers N, P, and K by up to 50%. The eco-enzyme + 50% N, P, K fertilizer produced shallot with the highest number of leaves per bulb and clump, number of bulbs per clump, circumference of bulbs, weight per bulb, and weight of bulbs per clump.

Abstract

The performance of hydroponic lettuce cultivation significantly depends on the precision of nutrient solution formulation, thus requiring the availability of nutrient elements in an optimal composition with high bioavailability. In hydroponic systems, AB Mix nutrients, which consist of two solution components (A and B), have become the standard application. Potassium, as an essential macronutrient, plays a crucial role in plant growth, particularly through enzymatic activation mechanisms that support metabolic processes and cellular biosynthesis. One of the challenges in hydroponic lettuce cultivation is the unknown optimal nutrient dosage and relatively high nutrient prices. The impact of K fertilizer application on the development and yield of lettuce plants is influenced by the amount of nutrient elements supplied through AB mix fertilizer, as well as the concentration levels used. This study aims to determine the concentration of AB mix nutrients and the addition of K fertilizer on the growth and yield of lettuce (Lactuca sativa L.) in a hydroponic setting. This research was conducted at The Zafarm. The method used in this study is a Randomized Block Design (RBD) with one factor divided into 9 treatment levels. Each treatment was conducted with three repetitions, resulting in a total of 27 experimental units. Since each unit consists of 4 individual plants, the total number of plants used is 108. The results of this study concluded that the application of AB mix general vegetable fertilizer at 1200 ppm + Potassium 250 ppm provides the best lettuce plant results, which can be measured by the increase in plant height, leaf area development, fresh weight, dry weight, as well as root length and volume, and dark green color, sweet taste, and crispy texture. The application of artificial formulation AB mix fertilizer has not been able to match the growth of plants using AB mix general vegetable fertilizer across all variables.
