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.

Abstract

Soybeans are the third most important commodity after rice and corn. Soybeans are also a commodity rich in protein. Soy serves as a very important source of vegetable protein to improve people's nutrition because in addition to being safe for health is also relatively cheap compared to animal protein sources. Ultisol has a wide distribution but has constraints to be used as a medium of cultivation plants. The addition of some types of ameliorating or soil reformers such as chicken manure, cow manure, and composting oil palm bunches (OPB) is expected to overcome ultisol fertility. The purpose of this study was to compare the influence of varieties on the growth and component of soybean crop yields in Ultisol, compare the influence of ameliorating type on the growth and component of soybean crop yields in Ultisol, and get the interaction between the type of varieties with the type of amelioration to the growth and components of soybean crop yields in Ultisol. The research was conducted from February to May 2019 in the experimental garden of Integrated Agricultural Zone of the Faculty of Agriculture UNIB Medan Baru, Bengkulu City. This study used a Complete Randomized Design (CRD) that was compiled factorially with 3 times. The first factor is the variety type Anjasmoro and Gepak Kuning, the second factor of amelioration type is control (without amelioration), chicken manure 15 tons ha-1, cow manure 15 tons ha-1, husks burn 15 tons ha-1, and compost oil palm bunches (OPB) 15 tons ha-1. The results showed that the Gepak Kuning variety showed better growth than the Anjasmoro variety while the Anjasmoro variety showed better results than the Gepak Kuning variety. Chicken manure is the best type of amelioration compared to cow manure, rice husks, and compost OPB against the growth and component of soybean yields in Ultisol, and there is interaction in the Gepak Kuning variety with chicken manure amelioration and compost OPB.

Abstract

This study aims to identify the physical, chemical characteristics of the soil and determine the suitability of rice fields for new openings in Mukomuko. This research was conducted from September to October 2019, which consisted of fieldwork and laboratory analysis. This research uses a survey method, soil sampling is carried out by a composite method consisting of 5 soil samples. Composite soil sampling technique based on land unit work maps produced from the map of soil types Mukomuko district scale of 1: 100.000. The results showed that all samples had the same dominant limiting factors namely P2O5, K2O, and Base Saturation. Land suitability for lowland rice plants in Mukomuko District Af.1.2.1 (S3nr) land area with an area of 42.68 ha, Af.1.2.2 (S3nr) land area with an area of 56.65 ha, land unit Tf.2.1 (S3nr) with an area of 60.15 ha, and land unit Tf.3.1 (S3nr) with an area of 89.30 ha.

Abstract

This study aims to obtain N levels and N absorption as well as the growth and yield of mustard plants in ultisol soilapplied vermicompost cattle or goats. This research has been conducted from April 2020 – May 2020. Implementation of research on UNIB garden and Soil Science Laboratory of Faculty of Agriculture, University of Bengkulu. This study used a Complete Randomized Design (CRD) with a single factor consisting of 7 treatments, namely control, vermicompost cow dung with a dose of 10 tons ha-1 , 20 tons ha-1 , and 30 tons ha-1 , and vermicompost goat manure with a dose of 10 tons ha-1 , 20 tons ha-1 , and 30 tons ha-1 . The results showed that the administration of vermicompost cow dung at a dose of 30 tons ha-1 gave the best results for N tissue levels, N absorption, and mustard results in Ultisol. The same result was obtained from the administration of vermicompost goat manure at a dose of 20 tons ha-1 .
