Abstract

Microgreens represent a novel approach to urban farming, characterized by its simplicity, straightforwardness, and cost-effectiveness. This research aims to evaluate the use of coconut water waste as a liquid organic fertilizer (POC) in promoting the growth of green bean microgreens (Vigna radiata). The study was conducted over one week in the Kotapinang District of South Labuhanbatu Regency, utilizing analysis of variance (ANOVA) to assess four treatments with varying doses of coconut water POC: P0 as the control, 10 ml, 20 ml, and 30 ml. The data collected were analyzed using SPSS version 25.00, and the BNT test was applied at the 5% significance level to evaluate the differences between treatments. The results of the observations indicated that at 4 days after planting (DAP), the P3 treatment yielded the greatest plant height, averaging 13.83 cm. Conversely, at 7 DAP, treatment P1 exhibited the highest growth, with an average plant height of 19.66 cm. In terms of leaf width, treatment P1 also performed the best, with an average leaf width of 1.2 cm. These findings suggest that the application of coconut water as POC can significantly enhance the growth of green bean microgreens.

Abstract

Corn (Zea mays L.) is a primary agricultural commodity in Indonesia, alongside rice and soybeans. This study aims to evaluate the growth of local corn plants in North Sumatra after applying various doses of bokashi fertilizer. The research was conducted in Perbaungan Village, Bilah Hulu District, Labuhanbatu Regency, North Sumatra, from December 2024 to February 2025. The study employed a Completely Randomized Design (CRD) with a one-factor experiment, focusing on applying bokashi fertilizer to corn plants. Five treatments were tested: Control (no application), 80 grams per polybag (4 x 20 grams every 2 weeks), 120 grams per polybag (4 x 30 grams every 2 weeks), 180 grams per polybag (4 x 40 grams every 2 weeks), and 200 grams per polybag (4 x 50 grams every 2 weeks). The parameters observed included plant height, number of leaves, and stem diameter. Data analysis was performed using the Tukey Test (BNJ) at a significance level of 5%. The results indicated that the application of bokashi fertilizer significantly influenced the growth of local corn in North Sumatra, with the most favorable outcomes observed at 8 weeks after planting (WAP). The highest plant height recorded was 141.65 cm (P4), the number of leaves was 11.50 strands (P3), and the stem diameter measured 2.73 cm (P4).
