Abstract

Lettuce (Lactuca sativa L.) is a horticultural plant that is beneficial for health. Efforts are being made to expand the plant area. One of them is by utilizing marginal land such as peatlands.  Peatlands in Indonesia are the most extensive soils in various tropical countries in the world that have low soil fertility and high acidity so that they are not optimal for lettuce growth. The provision of organic material can increase soil fertility by improving physical, chemical, and biological soil properties so that it can support lettuce growth. This study aims to determine the dose of cow manure and the dosage of oil palm empty fruit bunch fertilizer and the optimal dose interaction for growth and yield of lettuce. This research was conducted from June 2019 to August 2019 in Bengkulu City. This study uses a Completely Randomized Design consisting of two factors, which are repeated three times. The first factor is the dose of cow manure with three levels, namely: 0 tons ha-1, 15 tons ha-1, and 30 tons ha-1. The second factor is the dose of oil palm empty fruit bunch fertilizer, which consists of four levels, namely 0 tons ha-1, 5 tons ha-1, 10 tons ha-1, and 15 tons ha-1. The results showed that the dosage of cow manure 15 tons ha-1 and without the application of empty fruit bunches fertilizer gave the best results in leaf length of 18.674 cm. The best dose of cow manure for growth and yield of lettuce is 15 ha-1. The application of OPEFB fertilizer has not been shown to affect the growth and yield of lettuce.

Abstract

Shallots (Allium ascalonicum L.) are one of the horticultural commodities with high economic value and are needed by the community as food. Shallots also contribute to national inflation. Shallots become potential commodity to be developed in the region of North Sumatra, especially in the Toba region. One of the efforts to increase the growth and production of shallot plants can be done by applying SP-36 Fertilizer and Red Devil Fish Liquid Organic Fertilizer. This research aims to determine the best SP-36 and Red Devil Fish Liquid Organic Fertilizer, growth and production of shallots. The research was conducted from September to December 2023 in Lumban Silintong Village, Balige District, Toba Regency, North Sumatra with an altitude of ± 945 m above sea level. The design used was a factorial Randomized Group Design with three replications. The treatments studied were the first factor of SP-36 dose with four levels of treatment (0 (control), 112.5 Kg/Ha, 225 Kg/Ha, 337.5 Kg/Ha and the second factor was the dose of liquid organic fertilizer of red devil fish (0 (control), 3 g/plot, 5 g/plot). The results showed that the provision of SP-36 had a significant effect on the observed variable, namely the fresh weight of plants per plot. Giving Red Devil Fish Liquid Organic Fertilizer can significantly increase plant height, plant fresh weight per plot, plant fresh weight per sample, number of tubers per plot and tuber diameter.
