Abstract

[UTILIZATION OF MICROBE TO INCREASE GROWTH AND YIELDS OF SOYBEAN IN COASTAL LAND]. This study aims to obtain the precise combination of variety and biofertilizer to increase soybean productivity in Bengkulu coastal land. The research was conducted from March to July 2017, located at Beringin Raya Village, Muara Bangkahulu Sub-District, Bengkulu. The study was conducted using a split-plot design which was repeated three times. The main plot was two soybean varieties (Grobogan and Wilis). The subplots were two types of biofertilizers, arbuscular mycorrhizal fungi and phosphate solubilizing fungi. The result showed that the seed weight of the Grobogan variety (equivalent to 3.38 tons/ha) was significantly higher than the Wilis variety (equivalent to 2.72 tons/ha). However, the increment of the Wilis variety (equivalent to 1.12 tons/ha) was higher than the Grobogan variety (equivalent to 0.61 tons/ha) according to the description of each variety. The combination of arbuscular mycorrhizal fungi and phosphate solubilizing fungi showed superior performance than arbuscular mycorrhizal fungi or phosphate solubilizing fungi alone. The interaction of Grobogan varieties with a combination of arbuscular mycorrhizal fungi and phosphate solubilizing fungi produced the highest seed weight (equivalent to 3.52 tons/ha) which was statistically similar to the interaction of Grobogan varieties and arbuscular mycorrhizal fungi (equivalent to 3.45 tons/ha). In terms of economics of resources, the use of arbuscular mycorrhizal fungi is not required to be combined with phosphate solubilizing fungi.

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 .

Abstract

[CHANGE IN SOIL CHARATERISTICS AND PERFORMANCE OF UPLAND RICE VARIETIES IN COASTAL AREA AS AMENDED WITH BIOFERTILIZER AND BIOCOMPOST]. Dryland in the coastal area has good potential for the cultivation of upland rice to reach food self-sufficiency and the development of future agriculture. Low fertility of the land the area can be overcome by using appropriate technology such as the use of superior varieties, bio-fertilizers, and bio compost. This study aimeds to (1) determine chemical and biological properties of coastal land to improve the growth of upland rice (2) find out the growth of upland rice in the coastal area using low input technology and (3) obtain upland rice varieties with high adaptability to a coastal area environment. The experimental design used was a split-plot design with the main plot of 3 upland rice varieties, namely Inpago 10, Serantan, and Local Variety, while the subplots are were fertilizer inputs namely [double inoculant P solubilized microbial p (pf) + K solubilized microbially + N fixation microbial N], [double inoculant P solubilized microbial (fma) + K solubilized microbially + N fixation micarobia], [biocompost at a dose of 10 tons/ha], and [inorganic fertilizer recommended by BPTP ie 200 kg Urea/ha, 100 kg SP36/ha, 100 kg KCl/ha]. The results showed that the coastal area has the potential for the development of upland rice cultivation. Also, the double inoculants of biological fertilizers were able to increase plant nutrient uptake, soil biological characteristics, and the growth of upland rice as compared to controls. Specifically, the best treatment is produced by application of [double inoculant microbial solvent p (pf) + microbial solvent K + microbial N fixation] combined with upland rice Inpago variety 10.
