Abstract

Microgreen is a popular food product that is interesting to study and can be produced in the building with the support of artificial light, especially in terms of smart lights. This study aims to analyze the growth and yield response of red amaranth, red radish, and coriander microgreens under different types of light color treatment from smart lights. The study was conducted in August 2022 at the microgreen culture room, Department of Agronomy, Universitas Padjadjaran, Indonesia, using a completely randomized design with two factors, namely three levels of plant species and five levels of smart light color. The results showed differences in seed viability, first-day count, and the day the cotyledons were open among three microgreen species. Seed growth into microgreens had the same pattern, namely linear and positive, even in the light absence condition as the evidence of etiolation occurrence leading to the production of thin and yellow pale color of microgreens. The difference in light color is specific to each type of plant.  Red radishes thrived in all colors, although red light tended to do better. On the other hand, red amaranth was inhibited in red light and coriander in white light. Blue light is strongly recommended for increasing red amaranth and coriander microgreens yields.

Abstract

Rice productivity in Inceptisols is often constrained by high phosphate fixation and low nutrient efficiency, despite high total nutrient reserves. This study aimed to evaluate the effectiveness of silicaenriched biochar in improving soil chemical properties and maintaining rice yield under reduced N, P, K fertilization. A field experiment was arranged in a Randomized Block Design with two factors: silicaenriched biochar (0, 1.25, and 2.5 t ha-1) and N, P, K fertilizer dosages (0, 50%, and 100% of the  recommended dose). Observed parameters included Cation Exchange Capacity (CEC), available phosphorus, total soil silica, and yield components. The results showed a significant interaction between treatments on soil chemical properties, particularly CEC and pH. Application of 2.5 t ha-1 silica-enriched biochar independently increased available phosphorus by 24.3% and total soil silica by 5.9% compared to the control, likely due to phosphate desorption mechanisms. Agronomically, while N, P, K fertilizer was the dominant factor for yield, the combination of 2.5 t ha-1  silica-enriched biochar  with 50% N, P, K dosage produced Milled Dry Grain (MDG) yields that were statistically comparable to the 100% N, P, K treatment. This indicated that silica-enriched biochar can substitute up to 50% of inorganic fertilizer requirements without compromised yield
