Abstract

Mahogany (Swieteniamacrophylla King) is a type of forestry plant that is often used as a raw material in the timber industry and as a land rehabilitation plant. Vegetative propagation by shoot cutting becomes one of the alternatives way to cultivate Mahogany to anticipateits short-life seeds. The treatment of organic Growing Regulators on Mahogany shoot cutting is expected to increase the success of shoot cutting. This research was conducted to find out the influence of organic Growing Regulators substances such as Shallot Extract, Coconut Water, and Cow Urine, on the growth of mahogany shoots cuttings. The research method used Complete Random Design (RAL) with 13 treatments that are Control treatment (Aquades), Growing Regulators substances Shallot Extract, Coconut Water, and Cow Urine with 25%, 50%, 75%, 100% contingency respectively. The results showed that the treatment of organic Growing Regulators substances (Shallot Extract, Coconut Water and Cow Urine) significantly affected (95%) on the variable observation of the percentage of life and the increase in the length of mahogany shoots and significantly (99%) affected on the parameters such as the number of leaves and the length of mahogany shoots cuttings, but had no significantly affected on the period of its shoots growth. The organic Growing Regulators Shallot Extract treatment showed the highest influence on 3 observation variables. Treatment Connotation of Shallot Extract 100% is a treatment that shows the best growth compared to other treatments because it shows a high influence on almost all observed variables.

Abstract

Plant propagation is easy to do and does not require a lot of money it is propagation through seeds (generative). Efforts that can be made to reproduce teak plants by vegetative propagation used the seeding of tree shoots or by shoot – cuttings. In the propagation of shoot – cuttings that need to be considered is the use of the type of media planting and the use of growth hormones to accelerate root growth. This study was conducted to determine the interaction between the application of media planting and the duration of immersion the substance of Rootone-F on the growth of teak (Tectona grandis L.) shoot – cuttings. The experimental design carried out was a 2 (two) – factorial factor experiment that arranged completely randomly. The first factor was the length of immersion in the growth substance of Rootone-F, which consisted of 3 (three) levels, namely, direct immersion, 5 minutes of immersion, and 10 minutes of immersion; the second factor is the influence of planting media which consists of several doses on 5 (five) media planting, which includes, 1 – 2.5 kg of soil, 2.5 kg of sand, 1 – 2 kg of husk charcoal, 1 – 2 kg of sand, and 1 – 2 kg of compost. The results showed that the interaction of the application of Rootone-F and the media planting showed a significant effect on the age of the shoots – out and the length of the shoots. The factor of giving Rootone-F and media planting had a very significant effect on the parameter of observing the number of leaves.

Abstract

This research was carried out in Oematnunu Village, West Kupang District, Kupang Regency and the study was carried out from February to April 2022. The aim of this study was to determine the effect of the dose of cow dung manure and inorganic NPK on the growth and yield of mustard plants. The purpose of this study was to determine the dose combination of cow dung manure and inorganic NPK fertilizer that could provide the best growth and yield of mustard plants. This study is a single factor experiment designed in a completely randomized design (CRD) with 5 treatments in the form of doses of rice straw mulch. Each treatment combination was repeated 6 (six) times so that a total of 30 experimental units were obtained.The results showed that 1). The combination of cow dung manure and inorganic NPK had a very significant effect on plant height, number of leaves, total fresh weight, and total net weight of mustard plants. 2). The combination treatment of manure dose of 5 tons/ha and NPK 300 kg/ha, combination dose of 10 tons/ha and NPK 200 kg/ha, and 400 kg/ha NPK fertilizer gave the best results on plant height, number of leaves, total fresh gross weight of mustard plant, and total net weight of mustard plant.
