Abstract

This study aims to determine the optimum dossage of vermicompost to soil P levels, tissue P levels as well as corn growth and yield in Entisols. This research was conducted at Kandang Mas village, Bengkulu City from August 2019 until November 2019. The design used in this study is Randomized Complete Block Design (RCBD) one factor is the application of vermicompost dose with three replications. The dossage of vermicompost consists of seven levels, namely 0 tons ha-1, 5 tons ha-1, 10 tons ha-1, 15 tons ha-1, 20 tons ha-1, 25  tons ha-1, and 30 tons ha-1. The results showed that there was no optimum dossage of vermicompost to soil P levels, tissue P levels, and corn yield in Entisols.

Abstract

Soybean (Glycine max (L.) Merill) is the third most important food crop after rice and corn which contains protein and other nutrients essential for the body. Ultisol soil is a less fertile soil that has many limitations on its physical, chemical, and biological properties. Efforts that can be made include the use of liquid organic fertilizer (LOF) and arbuscular mycorrhizal fungi (AMF). This research was conducted from February to May 2020, in Beringin Raya, Muara Bangka Hulu District, Bengkulu City with an altitude of + 10 m above sea level. The purpose of this study was to explain the growth and yield of soybeans due to the application of liquid organic fertilizers and arbuscular mycorrhizal fungi in Ultisols. The research design used was a randomized complete block design (RCBD) with 2 factors with three replications. The first factor is the LOF dose which consists of four levels, namely: 0, 20, 40, and 60 mL L-1. The second factor is the AMF dose with three levels, namely; 0, 5, and 10 g plant-1. The results showed that there was no interaction between LOF and AMF. Giving a LOF concentration of 60 mL L-1 gave the highest yield on the growth and yield of soybeans, as well as the optimum concentration for seed/plant weight, which was 28.114 mL L-1, and the number of seeds was 37.589 mL L-1. AMF dosage of 10 g plant-1 gave the best growth and yield of soybean plants.
