Abstract

Cauliflower (Brassica oleracea var. botrytis L.) is one of the vegetables widely consumed by Indonesian people. Cauliflower productivity in Indonesia has decreased in recent years. Plant growth and production can be influenced by internal factors of the plant itself and external factors such as climate, soil, sunlight intensity, nutrients, and OPT. Fulfillment of plant nutritional needs is done by providing fertilizers, both organic fertilizers (biological and non-biological) and inorganic fertilizers. This study aims to test the use of organic solid biofertilizers on the growth and weight of cauliflower harvests. The research method used was a randomized block design (RAK) consisting of 6 treatments and 4 replications to obtain 24 experimental units. The treatments used were treatment A (100% solid biofertilizer), treatment B (solid biofertilizer + 75% dose of inorganic fertilizer), treatment C (solid biofertilizer + 50% dose of inorganic fertilizer), treatment D (solid biofertilizer + 25% dose of inorganic fertilizer), treatment E (100% dose of inorganic fertilizer), and treatment F (without fertilization/control). The results showed a significant effect on the provision of solid biofertilizer and inorganic fertilizer on plant height, number of leaves, and wet weight of the harvest, while the stem diameter had no significant effect. Meanwhile, there was no significant difference between the treatments of using solid biofertilizer and inorganic fertilizer.

Abstract

The aim of this research is to analyze the effect of different types of organic fertilizer (solid biological, liquid biological and foliar) on the growth and productivity of tomato plants. This research was carried out for 3 months starting from February to April 2024. This research used a Randomized Block Design (RAK) consisting of 14 treatments, namely: solid biological fertilizer (100%), liquid biological fertilizer (100%) and foliar organic fertilizer (100%) with inorganic fertilizer doses of 25%, 50% and 75%. There were 14 treatment combinations with 3 repetitions. The observation variables are plant height, number of leaves, stem diameter and plant weight. The results of the research showed that the best treatment for plant height was liquid biofertilizer + 25% dose of inorganic fertilizer (83.47 cm), for number of leaves, namely liquid biofertilizer and leaf organic fertilizer (7 pieces), for stem diameter, 100% biofertilizer (6.20 cm) and for plant weight, namely organic leaf fertilizer + 75% dose of inorganic fertilizer (56.39 g).
