Abstract

Common waste materials like eggshells (ES), spent coffee grounds (SCG), and banana pseudostems (BS) are abundant in both society and agriculture. However, their underutilization leads to their accumulation in landfills, resulting in significant environmental problems. This research aims to investigate the potential of banana pseudo-stem. spent coffee ground and eggshell waste in improving Kangkong (Ipomoea reptans. Poir) vegetable growth parameters. The research was conducted at a shaded plantation site located at Tunku Abdul Rahman University Management and Technology from January–May 2024. The ES, SCG and BS waste used in this study was collected, dried, grinded, and sieved before being used in the experiment. Three different types of soil which are organic soil, normal soil and cocopeat with ratio 2:1:1 as a growing medium. The study used the complete random design (RAL) method of 15 repetitions and 8 factors: P0 = Negative control (0%), P1 = 50% banana pseudostem + 20% of eggshell liquid, P2 = 35% banana pseudostem + 20% of eggshell liquid, P3 = 5% banana pseudostem + 20% of eggshell liquid, P4 = 50% banana pseudostem + 5% of eggshell liquid, P5 = 35% banana pseudostem + 5% of eggshell liquid, P6 = 5% banana pseudostem + 5% of eggshell liquid, P7 = Garbage enzyme and P8 = NPK 15-15-15 as a positive control. The experiment was carried out over 35 days, with measurements of the plant's height, number of leaves, area of the leaves, fresh weight and dry weight of the plant, root length, shoot length and root to shoot ratio. The chemical analyses of eggshell, spent coffee ground, banana pseudostem, garbage enzyme, chemical fertilizer, organic soil, normal soil and cocopeat were performed using CHNS/O, MP-AES and Kjeldahl method to determine the nutrient content which is nitrogen, phosphorus and potassium. The data were analyzed using SPSS version 27 one way ANOVA. The results of this study could lead to further investigation of the suitable amount of EC, SCG and BS in the soil medium growth and potential to supplement fertilization to support the plant growth. P5 shows the highest growth yield with average height, area of leaves, shoot length and root length of 14.40 cm, 29.53 cm2 and 9.050 cm, respectively compared to other treatments except for P8.
