Abstract

This study aims to determine the effect of biochar and microbial application on the growth and yield of sweet sorgum (Sorghum bicolor L.) in in seawater-intruded media. Biochar functions to improve soil structure and increase water retention and nutrient efficiency, while tobacco microbes have the potential to act as biological agents. The study employed a Split-Plot Design with two factors: biochar (0, 40, 80, 120 g/polybag) and microbes (0, 5, 10, 15 ml/polybag), each with three replications. Analysis results indicated that biochar application significantly influenced the parameters of seeds per panicle and seed weight per plot. The biochar treatment at a dose of 80 g/polybag produced the highest number of seeds per panicle at 74.54 seeds, while the treatment without biochar (B0) yielded the highest seed weight per plot at 57.65 g. The application of microorganisms and the interaction between biochar and microorganisms did not show a significant effect on all observed parameters. Biochar was proven effective in increasing sorghum yield on salt-intruded land through improved generative growth when applied at the optimal dose.

Abstract

Kesum (Persicaria minor Huds.), a plant rich in flavonoids such as quercetin and quercetin-3-glucuronide, holds significant value as a traditional medicine and distinctive culinary herb, particularly in West Kalimantan. This study evaluated the effects of five nitrogen concentrations (0, 50, 100, 150, and 200 mg L⁻¹) on the growth and phytochemical accumulation of kesum cultivated using a floating-raft deep water culture (DWC) hydroponic system. The experiment was conducted in a greenhouse at MARDI, Malaysia, employing a randomized block design with five replications. The results revealed highly significant effects of nitrogen (p < 0.01) on all measured growth and phytochemical parameters. Key findings include the highest plant height (80.33 cm) at 100 mg L⁻¹ nitrogen, maximum biomass production (fresh weight 176.64 g and dry weight 43.99 g per 30 plants) at 150 mg L⁻¹ nitrogen, and a substantial increase in phytochemical content at 50 mg L⁻¹ nitrogen, with quercetin-3-glucuronide reaching 98 µg/mg and quercetin 67 µg/mg—2 to 3 times higher than the control. In contrast, 200 mg L⁻¹ nitrogen caused toxicity, resulting in reduced biomass and phytochemical levels. Based on these findings, the optimal nutrient recommendations are 100–150 mg L⁻¹ nitrogen (with phosphorus maintained at 150 mg L⁻¹ and potassium at 200 mg L⁻¹) for commercial production aimed at maximizing fresh leaf yield and biomass, and 50 mg L⁻¹ nitrogen for cultivation focused on maximizing bioactive compound content for phytochemical extraction and the phytopharmaceutical industry.
