The responses of soil enzyme and microbial activities of shallot plantation under treatments of Liquid Organic Biofertilizer and sprout extract and its effect on the yield

Abstract

Soil enzymes activities can be used to measures of microbial activity, soil productivity, soil ecology and fertility. Soil enzyme and microbial activities act as the indicators of soil health. The objectives of this study were to examine the influence of liquid organic biofertilizer and sprout extract on soil enzyme and microbial activities and their effect in shallot yield. The experimental design was completely randomized block design with three different treatments as following liquid organic biofertilizer (LOB), sprout extract (SE), and mixed of liquid organic fertilizer and sprout extract. The result showed that treatment of LOB gave the highest activity of phosphomonoesterase and urease measured, and followed by SE, LOB+SE and control. The LOB treatment showed the highest microbial respiration as also indicated in the highest population number of total bacteria. However, LOB + SE treatment gave the highest number of IAA producing bacteria as well as the yield of shallot. Therefore, it is confirmed from this work that application of liquid organic biofertilizer and sprout extract potentially could increase soil enzyme activities, microbial population number and the yield of shallot.

The role of rhizosphere microbes as phosphate solubilizing bio fertilizers in shallot: a review

“…Bio fertilizer of P solvent is a fertilizer enriched with beneficial microorganisms and growth regulators which function to overcome land degradation [128,129], able to increase shallot production and activity phosphomonoesterase enzymes by increasing the population of bacteria in the rhizosphere [130]. Penicillium, Pseudomonas, Flavobacterium, Bacillus, Micrococcus, Fusarium, Aspergillus, and Sclerotium are P-solvent microbes [131] which can be isolated from cassava and sunflower skin waste which produce the fungi Aspergillus flavus, A. niger, Enterobacter, and Burkholderia [132,133].…”

Efektivitas Beberapa Jenis Pupuk Hayati Terhadap Produksi Kacang Merah Varietas Inerie

“…Selain Bioboost, pupuk hayati lainnya yang digunakan dalam penelitian ini yaitu Liquid Organic Biofertilizer, Bion-Up, M-Bio, Bio-Konversi, Bio HYT, dan Bio CBA Grow rata-rata mengandung mikroba yang sangat membantu dalam pertumbuhan tanaman. Liquid Organic Biofertilizer mengandung mikroba penambat N, pelarut P, dan pelarut K, serta mengandung Fitohormon alami yang dihasilkan dari metabolisme mikroba (Dewi, et al, 2021). Bion Up mengandung bakteri pemfiksasi Nitrogen (Azotobacter chroococcum, A. vinelandi, Azospirilum sp, dan Acinetobacter), bakteri pelarut fosfat Pseudomonas cepacia, jamur Penicillium sp pelarut fosfat (Ansory, et al, 2021).…”

Influence of Organic-Biofertilizers and Foliar Spray with Different Biostimulants on Increasing Yield and Essential Oil of sweet marjoram (Marjorana hortensis L.) Plant

“…These enzymes activity can be a good indicator of the quality and quantity of organic matter that promote microbial growth in soils. Also, indicates for healthy and fertility soil (Dewi et al, 2021). The chemical composition of herbage -Endogenous phytohormones content of leaves Fig (3) shows the content of endogenous phytohormone of marjoram leaves such as auxine (indole acetic acid IAA and gibberellic acid GA3) as growth stimulating hormones.…”
