 COVID-19 pandemic has become a major crisis in 2020. The pandemic has claimed thousands of lives and is spreading a negative economic impact around the global economy. The pandemic has caused a devastating impact on human life in many of the countries without a clear distinction among developed or developing nations. Sri Lanka is facing the heat of the pandemic gradually since January and has taken various measures to combat the situation. The COVID-19 pandemic forwarded a greater challenge to Sri Lanka since the country has faced various disasters in the recent past and question marks remain about the government’s response. The Sri Lankan government response to the current COVID-19 crisis has been largely successful and is ranked among the best responsive countries in the world. This paper discusses Sri Lanka’s strategies in dealing with COVID-19 pandemic and possible future challenges related to the issue.

This study aims to identify the effects of mycorrhiza arbuscular and phosphate source fertilizer on the growth and nutrients absorption of soybean on critical land. The research was carried out in the experimental garden of Agricultural Faculty, University of Syiah Kuala Darussalam, Banda Aceh. The research was done in an experiments using polybag of random design group (shelves) consisting 2 factors, namely mycorrhiza arbuscular consisting of 4 standards without mycorrhiza, glomus 10 g, mycorrhiza gigaspora 10 g, and mixture glomus 5 g + gigaspora 5 g and phosphate fertilizer consisting 4 factors namely without phosphate fertilizer, rock fosfat, guano, and SP-36. The result showed that the interaction effect of mycorrhiza glomus and guano phosphate application improved growth and nutrients absorption of soybean plants. Key words: Gigaspora, Glomus, guano, rock phosphate, soybean, SP-36/>

Phosphate solubilizing bacteria have the ability to solubilize the insoluble phosphates and to improve the quality of soil health and fertility. Efficacy of phosphate solubilizing microorganisms has been identified on the basis of kinetics and phosphorus accumulation. In this study, twenty eight soil samples were collected from different coal mines landfills of Chhattisgarh and occurrence of phosphate solubilizing bacteria (PSB) was isolated, purified and identified. In addition, the phosphate solubilizing capacity of bacteria based on the formation of visible or halo zone on Pikovskaya agar plates (PVK) and broth having tricalcium phosphate (TCP) and rock phosphate (RP) as a phosphate source was estimated at Dr. C.V. Raman University, Kota, Bilaspur (Chhattisgarh). The result revealed dominance of Pseudomonas syringae as major phosphate solubilizers, along with Bacillus subtillis followed by Pantoea dispersa, Bacillus circulans. Use of these PSB as bioinoculants increased the available P in soil to the extent of 194 and 246 µg/ml of P. the soluble P in case of rock phosphate was less than tricalcium phosphate. The maximum solubilization was observed after 15 days follow by a decrease in amount of soluble P.
