Abstract

This study aimed to evaluate the effect of cattle manure and ZA fertilizer on the growth and yield of shallots (Allium ascalonicum L.) cultivated on Ultisol soil. The experiment was conducted in Medan Selayang, from January to April 2024, using a two-factor Randomized Block Design (RBD) with three levels of cattle manure and four levels of ZA fertilizer. Data were analyzed using analysis of variance followed by Duncan’s multiple range test. The results showed that cattle manure at a dose of 30 g per polybag significantly increased fresh bulb weight per plot, but had no significant effect on plant height, leaf number, other bulb yield parameters measured. ZA fertilizer significantly affected leaf number and stored bulb weight per plot, but showed no significant influence on other growth and yield traits. The interaction between cattle manure and ZA fertilizer showed no significant effect on all observed parameters.

Abstract

This study aims to determine the effect of soaking time and coconut water concentration on the dormancy breaking of oil palm seeds (Elaeis guineensis Jacq.). This study used a Factorial Completely Randomized Design with two factors. The first factor is the concentration of coconut water (A): A1 = 25% coconut water/liter of water, A2 = 50% coconut water/liter of water, and A3 = 75% coconut water/liter of water. The second factor is the soaking time (L): L1 = 30 minutes, L2 = 60 minutes, and L3 = 90 minutes. Data analysis was conducted using variance analysis and Duncan's test. The results showed that the concentration of coconut water significantly affected germination power, germination age, plant height, and the number of leaves of oil palm seedlings. A 75% concentration of coconut water produced the best dormancy breaking of oil palm seeds. The soaking time in coconut water solution also significantly affected germination power, germination age, plant height, and the number of leaves of oil palm seedlings. A soaking time of 90 minutes resulted in the best dormancy breaking of oil palm seeds. The interaction between coconut water concentration and soaking time significantly affected the germination power of oil palm seeds. This study provides important information on the optimal soaking conditions to improve dormancy breaking success, which can be used to accelerate the germination and growth of oil palm seedlings.
