Abstract

Shallot production in Indonesia has not been able to meet market needs due to the scarce availability of subsidized chemical fertilizers. Another alternative to replacing chemical fertilizers can be using Liquid Organic Fertilizer. The aim of this research was to determine the effect of watering time and concentration of liquid organic fertilizer on the growth and production of shallots (Allium ascalonicum L.). The design in this study was a Randomized Block Design (RAK), consisting of 2 treatment factors, namely watering time (W) consisting of 2 treatment levels, namely: W1= 1x1 week, W2= 1x2 weeks and POC concentration (P) consisting of 4 treatment levels namely: P1= 2 ml/240 ml water/plant, P2= 4 ml/240 ml water/plant, P= 6 ml/240 ml water/plant and P4= 8 ml/240 ml water/plant. Data analysis uses analysis of variance, if the treatment factor has a significant effect on the variance test, a mean difference test is carried out using the Duncan Multiple Range Test (DMRT) at 5% level. The results showed that POC watering time had a significant effect on tuber diameter and number of tubers per sample, but had no significant effect on fresh weight of tubers per sample and dry weight of tubers per sample. POC concentration had a significant effect on tuber diameter, number of tubers per sample, fresh weight of tubers per sample and dry weight of tubers per sample.

Abstract

Generative propagation of Mucuna bracteata is complicated and requires special treatment to germinate. Mucuna has a thick, rigid, and impermeable seed coat, which becomes a mechanical barrier to water or gas entry, making the imbibition process challenging to occur. Breaking dormancy in mucuna seeds aims to increase germination. This study aims to determine the effect of soaking time for mucuna seeds (Mucuna bracteata) at different water temperatures on breaking dormancy. This study used a completely randomized design factorial. This study consists of 2 treatment factors. The first factor is the length of soaking (L), which consists of 3 levels: 30 minutes, 60 minutes and 90 minutes. The second factor is water temperature (K), which consists of 3 levels: 30 °C, 60 °C and 90 °C. Data analysis used variance analysis and simple regression analysis. The results of the study showed that water temperature had a significant effect on increasing germination power, accelerating germination, increasing the number of normal sprouts, and the dry weight of mucuna (Mucuna bracteata) sprouts..

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.
