Abstract

[CHANGE IN SOIL CHEMICAL CHARACTERISTICS AND YIELD OF MAIZE IN AN INCEPTISOL AS AMENDED WITH COMPOST]. Vast area of inceptisol in Indonesia is a potential natural resource for improving the domestic maize production. The amendment of organic material is expected to make correction on the fertility problem inherent in the soil. Objective of this study was to determine the optimum dose of compost for some soil chemical properties and maize performances. The doses of compost consisted of 0, 2.5, 5, 7.5, 10, and 12.5 ton/haa were allotted randomly on the experimental plots according to completely randomized design with three replications. Observations were made on  the exchangeable Aluminum (Al-dd), pH, organic carbon, water content, plant height, unhusked and husked ear weight, and grain yield. Analysis of variance showed that the dose of compost had significant (P?0.05) effects on pH and C-organic in soil. Giving compost at a dose about 12.5 ton/ha could increase the pH about 4.9, whereas giving compost at a dose about 10 tonha-1 could increase C-organic about 3.09 %. In other hand, the giving of compost with various dose did not give significantly (P>0.05) affect towards  Aluminium (Al-dd), pH, C-organic, water content, height of plants, weight of without husk, weight of cob with husk, weight of dry corn beans. The highest grain yield (2,415.75 kg/ha) was observed on compost applied at  dose  12.5 ton/ha.

Abstract

Public gold mining carried out without permission and not organized is rife in Riau. Until now there is still lack of information about Unlicensed Gold Mining (UGM) in Kuantan Singingi District specifically Singingi subdistrict, Kuatan Tengah, Sentajo Raya and Logas Tanah Darat. The former gold mining land cannot be used for agricultural activities. To overcome this problem reclamation needs to be done on the former gold mine land. However, before the step is taken, the initial step is mapping the point of the location of the former gold mine, general conditions, land ownership status and mining processes, vegetation in UGM land and the impact of UGM in Singingi subdistrict, Kuatan Tengah, Sentajo Raya and Tanah Darat Logas. This study aims to map the distribution of land of the former gold mine, determine general conditions, land ownership status and mining processes, vegetation of former UGM land and the impact of UGM in Singingi District, Central Kuatan, Sentajo Raya and Tanah Darat Logas, in Kuantan Singingi District. The parameters observed were: point of distribution of the location of the former gold mine, general conditions, land ownership status and the mining process, vegetation of former UGM land and the impact of UGM. The results showed that in all subdistricts sample namely Singingi, Kuatan Tengah, Sentajo Raya and Tanah Darat Logas in Kuantan Singingi Distric there were unlicensed gold mining along the river flow area. Overall land ownership status is owned by individuals/individuals (people with capital) and land used for mining activities that are owned by others rent. There are three types of species that grow on the former gold mine land that is Melastoma malabathricum L., Cyperus halpan L. and Scleria sumatrensis Retz. While the real impact of unlicensed gold mining activities is the loss of river water bodies.

Abstract

The need for soybean commodities is increasing in line with increasing changes in population and public awareness of the importance of food nutrition. One of the efforts to increase soybean production is to improve crop cultivation by selecting superior varieties. The purpose of this study was to obtain soybean varieties that had the best growth response and yields by adding dolomite to a saturated soil culture (SSC). This research was carried out from November 2020 to February 2021 in the experimental land of the Department of Agricultural Cultivation, Faculty of Agriculture, University of Bengkulu. The design used was a randomized completely block design (RCBD) factorial pattern consisting of two factors. The first factor was the dolomite dose which consisted of 4 levels, namely 0 x Al-dd, 0.5 x Al-dd, 1 x Al-dd, and 1.5 x Al-dd. The second factor was soybean varieties consisting of Gepak Kuning, Dering 1, and Derap 1 varieties. The results showed that Gepak Kuning produced the best growth response and yield by adding dolomite to SSC.

Abstract

Improvement of Ultisol soil chemical properties can be done by adding organic matter. In this study, vermicompost was used from various animal wastes (chickens, goats and cows), and the optimal growth parameters and nutrient uptake were observed. Research results showed The chicken manure vermicompost had the maximum available P, the goat manure vermicompost had the highest available K, and cow manure vermicompost had the highest total N value. In terms of pH, goat manure vermicompost had the highest pH and the chicken manure vermicompost had the most excellent C/N ratio. Analysis of variance (Anova) showed that the type and dosage of vermicompost had a significant effect on growth parameters (plant height, number of leaves and stem width) and nutrient uptake of N, P and K
