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

Salacca sumatrana (Becc.), known locally as the Sidimpuan snake fruit, is one of the prime local commodity specialties of Padangsidimpuan City in Sumatra. The fruit is known for its sweet, sour, and astringent taste, which differentiates it from Pondoh and Balinese snake fruits. Recently, snake fruit farmers have noticed a continuous decrease in production due to failure in fruit set, particularly during the off-season. The use of fertilization and drip irrigation during the off-season has therefore been explored as a potential solution. Hence, this research investigated the use of these methods to overcome fruit-set failure and to ensure continuous production of Sidimpuan snake fruit throughout the year. Specifically, this study aimed to determine the optimal dosage of ammonium sulfate fertilizer and the appropriate drip irrigation level to improve fruit setting during the off-season. This research employed a split-plot design, with drip irrigation as the main plot and ammonium sulfate fertilization as the subplot. The observed parameters included the number of flower and fruit bunches, fruit-set percentage, and leaf nutrient content. Drip irrigation significantly affected fruit-set percentage and the number of harvested fruit bunches. The best treatment combination was 400 g ammonium sulfate fertilizer per plant combined with drip irrigation at 3,000 mL per plant. Fertilization applied during July–September resulted in an off-season harvest that was comparable to the on-season harvest fertilized during April–June, with differences of 10.76% in fruit-set percentage and 25.65% in the number of fruit bunches. These results indicate that the application of ammonium sulfate fertilizer combined with drip irrigation can overcome fruit-set failure in Sidimpuan snake fruit, particularly during the off-season.
