Abstract

Nursery is the activities in order to the plants grow uniformly. One of the factors affecting cacao nursery is watering. It aims to fulfill the water needs of plants. Water is important because it is a major component in the cells as compiler of plant tissue. So, the objective of this study was to determine the best volume of water on the growth of cacao seedlings. The research was conducted on September 2019 until January 2020 located in the greenhouse of 3rd Campus Andalas University, Dharmasraya, West Sumatra. The research method was a Completely Randomized Design (CRD) by 4 treatments and 5 replications so obtained 20 experimental units, each of it consisted of 2 cacao seedlings so that 40 plant samples were obtained. Several treatment levels were 150 ml water volume / polybag (V1), 300 ml water volume / polybag (V2), 450 ml water volume / polybag (V3), and 600 ml water volume / polybag (V4). The observation variables were plant height, leaf width, stem diameter, number of leaves, root length and plant dry weight. Regression analysis was performed to know the relationship among observed variables. The results showed that the application of 450 ml water / polybag (V3) generate the best results for plant height, leaf width, stem diameter, number of leaves, plant dry weight, and root length of 1-4 months cacao seedlings. The result of regression analysis showed that there was a close relationship among the plant dry weight of cocoa seedlings with the plant height, stem diameter and number of leaves.

Abstract

Rubber plants are an important plantation commodity as a source of non-oil and gas foreign exchange for Indonesia so they have a bright future. Propagation of rubber plants by grafting depends on the quality of the rootstock, and the graft as well as the grafter. The rootstock for rubber seedlings comes from seeds classified as recalcitrant. They have high moisture content, short shelf life, quickly loose their ability to germinate, and their cells freeze if stored at temperatures below 0oC. This study aimed to extend the shelf life of rubber seeds using a wax coating technique. The study was carried out for 2 months at the Unand campus III laboratory. A completely randomized divided plot design consisting of two factors, namely application of wax layer and shelf life was used. Application of wax slowed rubber seed germination. Various explanations are possible for this observation. One is that the ratio of wax/water in the suspension used to apply the wax layer was not appropriate. The longer the seeds were stored the lower the percentage germination observed. Therefore, further research should be conducted using less than 50% wax in the suspension use to coat the seeds.
