Abstract

This study aims to determine the effectiveness of the duration of soaking garlic extract and the provision of shell fertilizer on the growth of rose plant cuttings (Rosa hybrida L). This study used a Factorial Randomized Block Design (RAK) method consisting of 2 factors with 48 plots, namely: The first factor is the duration of soaking garlic extract given the symbol "A" which consists of 4 levels of treatment A0: without soaking, A1: 40 minutes, A2: 80 minutes, A3: 120 minutes The second factor is the provision of shell fertilizer given the symbol "B" which consists of 4 levels of treatment B0: 0 g / polybag, B1: 50 g / polybag, B2: 100 g / polybag, B3: 150 g / polybag. So there are 16 combinations consisting of 3 replications. The parameters observed in this study are the age of shoot emergence, number of leaves, shoot length, number of leaves, leaf length, and percentage of survival. The results of the study showed that the duration of soaking garlic extract and the application of shellfish fertilizer on the growth of rose cuttings (Rosa hybrida L). The results of this study showed that the duration of soaking garlic extract and the application of shellfish fertilizer had no significant effect on all observed parameters.

Abstract

This study aimed to determine the effect of various growing media on the growth and production of lettuce (Lactuca sativa L.) in a hydroponic system. The study used several types of growing media, namely rockwool, cocopeat, hydrogel, oil palm empty fruit bunches, rice husk charcoal, and sand. The observed parameters included plant height, number of leaves, stem diameter, fresh weight per treatment, economic harvest weight, and root length. The results of the analysis of variance showed that different growing media had no significant effect on the number of leaves, stem diameter, fresh weight, economic harvest weight, and root length of lettuce plants. However, the plant height parameter showed a highly significant effect at 20, 25, and 30 days after planting (DAP). Descriptively, rockwool as the control medium showed the highest growth and production, while organic media such as cocopeat, oil palm empty fruit bunches, and rice husk charcoal were also able to support plant growth well. Overall, all tested growing media can be used as alternative media in hydroponic lettuce cultivation because they are able to support plant growth and production relatively equally.
