Abstract

Pakcoy (Brassica rapa subsp. chinensis) and caisim (Brassica juncea) are leafy vegetables of the Brassicaceae family that are widely cultivated using hydroponic systems due to their fast growth, favourable economic value, and strong demand in urban markets. However, hydroponic cultivation of both commodities remains constrained by insect pest infestations that may reduce the quality and quantity of the harvest. This study aimed to identify insect species associated with hydroponically grown pakcoy and caisim under two installation systems, Deep Flow Technique (DFT) and Nutrient Film Technique (NFT), at the Experimental Garden of the Faculty of Agriculture, Universitas Muhammadiyah Palembang, and to quantify the resulting plant damage. The study employed a survey method through direct observation and damage scoring of sample plants over four weeks of observation. Data were analysed descriptively and presented as insect population tables and damage intensity values. Eleven insect species were recorded, comprising six pest species (aphids (Aphididae), diamondback moth larvae (Plutella xylostella), rice bug (Leptocorisa oratorius), southern green stink bug (Nezara viridula), leaf-footed bug (Leptoglossus zonatus), and the torpedo bug), three natural enemies from the family Coccinellidae, and two additional species (Platypezidae and Milichiidae) considered ecologically neutral. Aphids were the most dominant pest, with a population exceeding 1,000 individuals. Damage intensity increased from 0% in the first week to the fourth week of observation, with pakcoy showing higher damage (12.00%) than caisim (5.44%), and the DFT system showing higher damage than the NFT system. These findings provide a basis for integrated pest management in hydroponic pakcoy and caisim cultivation.

Abstract

Black rice (Oryza sativa L. indica) is a functional food rich in anthocyanins with health benefits, although its cultivation among farmers remains limited. This study aimed to determine the growth and yield response of various black rice genotypes grown on irrigated paddy fields. The study was conducted in Rantau Durian Village, Ogan Komering Ilir Regency, South Sumatra, using a Randomized Block Design with three genotypes, namely Intan Semar, Jeliteng, and Cempo Ireng, each replicated nine times. Data were analyzed using analysis of variance, followed by the Honestly Significant Difference (HSD) test at the 5% and 1% levels. The results showed that genotype had a highly significant effect on all observed variables. The Cempo Ireng genotype showed the best growth and yield response compared to Intan Semar and Jeliteng, with a plant height of 143.40 cm, total tiller number of 21.40 hills, filled grain weight per plot of 1.90 kg, 1000-grain weight of 24.33 g, and grain yield of 9.90 ton ha⁻¹, followed by Intan Semar with relatively similar performance, while Jeliteng consistently showed the lowest values for all observed variables. Cempo Ireng and Intan Semar are recommended as more adaptive black rice genotypes for cultivation in irrigated paddy field agroecosystems.
