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.

Abstract

The purpose of this study was to determine the effect of Potassium Fertilizer and Chicken Manure on the Growth, Production and Potassium Absorption of Sweet Corn Plants. This study used a Randomized Block Design (RAK) consisting of 2 factors. The first factor is Potassium Fertilizer (K) consisting of 4 levels, namely:K0 = Control (Without fertilizer), K1 = 7.2 g/plot, K2 = 14.4 g/plot, K3 = 21.6 g/plot. The second factor of Chicken Manure Fertilizer (C) consists of 3 treatment levels, namely: C1 = 2160 g/plot, C2 = 2880 g/plot, C3 = 3600 g/plot. The results of this study indicate thatPotassium fertilizer treatment had a significant effect onplant height, weight of cobs with husks per plant, weight of cobs per plot.The treatment of chicken manure has a significant effect onplant height, weight of cobs with husks per plant, and weight of cobs per plot.The interaction between potassium fertilizer and chicken manure had no significant effect on all observation parameters.

Abstract

This study aims to determine the effect of cow manure and liquid organic fertilizer eco farming on the growth and production of shallots (Allium ascalonicum L.). This research method uses a Factorial Randomized Block Design (RAK) consisting of 2 factors. The first factor is cow manure (P) consisting of 4 treatment levels, namely: P0 = Control (Without Compost), P1 = 0.5 kg/plot (5 tons/ha), P2 = 1.0 kg/plot (10 tons/ha) and P3 = 1.5 kg/plot (15 tons/ha). The second factor: Eco Farming consists of 3 treatment levels: C1 = 150 ml/plot, C2 = 250 ml/plot, and C3 = 350 ml/plot. The study's results showed that the provision of cow manure significantly affected plant height, number of leaves, wet weight of tubers per sample, and wet weight of tubers per plot. Providing eco farming impacts plant height, number of leaves, dry weight of tubers per sample, and wet weight of tubers per plot. The interaction between cow manure and eco farming had no significant effect on plant height, number of leaves, dry weight of tubers per sample, and wet weight of tubers per plot.
