This study aims to present a systematic data-driven bibliometric analysis of the water hyacinth (Eichhornia crassipes) infestation problem around the globe. As many solutions are being proposed in academia for its management, mitigation, and utilization, it requires investigation through a systematic scrutinizing lens. In this study, literature records from 1977 to June 2020 concerning research on water hyacinth are taken from Scopus for text analysis. Trends in the publication of different article types, dynamics of publication, clustering, correlation, and co-authoring patterns between different countries are observed. The cluster analysis indicated four clusters viz. (i) ecological works related to species, (ii) pollutant removal process and methods, (iii) utilization of biofuels for biogas production, and (iv) modelling works. It is clear from the networking analysis that most of the publications regarding water hyacinth are from India, followed by China and the United States. Sentiment analysis with the AFINN lexicon showed that the negative sentiment towards the aquatic weed has intensified over time. An exploratory analysis was performed using a bigram network plot, depicting and outlining different important domains of water hyacinth research. Water hyacinth research has passed the pioneering phase and is now at the end of a steady growth phase or at the beginning of an acceleration phase. In this article, an overview is given for the entirety of water hyacinth research, with an indication of future trends and possibilities.

This study investigates the potential of biogas production from water hyacinth, water lettuce and water fern. Laboratory experiments were carried out at the Faculty of Agriculture laboratory, University of Benin, Nigeria. The aquatic weeds which are major constituents of the substrate were contained in the conical flasks used as digester. The cow dung and aquatic weeds were mixed in the ratio of 1:1; 1:2; 1:3; 1:4; and 1:5 in the different samples used for each of the three aquatic weeds and gas produced measured.The results obtained showed that no gas was produced in any of the flasks containing the aquatic weed within 21days. Gas production was however recorded in those with cow dung alone which gave 302ml of biogas within the 21 days retention period with an average of 21ml of gas produced within the active 14 days of production. The results also showed variations in gas production between daytime and night hours with minimal gas production recorded at night hours and peak production during the daytime. It was concluded that cow dung requires shorter retention time to initiate production of biogas when compared with that of the aquatic weeds and therefore can be used to sustained biogas production in aquatic weed at the early stage.

O objetivo deste estudo foi avaliar a influência de diferentes períodos de chuva ocorridos após a aplicação do herbicida imazapyr, em sua eficiência de controle sobre plantas de Pistia stratiotes e Eichhornia crassipes. Foram estudadas chuvas de 10 mm, aplicadas durante 5', em diferentes períodos de tempo (0h, 2h, 4h, 6h, 8h, 12h, 24h e não simulação de chuva) após a aplicação de imazapyr, na formulação Arsenal NA, a 250 g i.a. ha-1(1,0 L p.c. ha-1). O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições. As plantas foram avaliadas visualmente aos 7, 14, 21, 28 e 35 dias após a aplicação (DAA), sendo os resultados obtidos submetidos à análise de variância pelo teste F e as médias dos tratamentos comparadas pelo teste de Tukey (p<0,05). A ocorrência chuvas em até 6 horas após a aplicação do herbicida imazapyr, em plantas de P. stratiotes, afetou negativamente sua eficiência de controle e, chuvas após intervalos acima de 8 horas não influenciaram no controle. A ocorrência de chuva em todos os intervalos de tempo, não interferiu no controle de plantas de E. crassipes.   UNITERMOS: aguapé, alface-d'água, controle químico, fitointoxicação     CAMPOS, C.F.; SOUZA, G.S.F.; PEREIRA, M.R.R.; MARTINS, D. EFFECT OF RAINFALL ON  IMAZAPYR  ACTION IN AQUATIC WEED CONTROL     2 ABSTRACT   The aim of this study was to evaluate the influence of different periods of rainfall that occurred after the application of the imazapyr herbicide on the control efficiency of Pistia stratiotes and Eichhornia crassipes. We studied 10 mm rainfall, applied for 5' at different time periods (0h, 2h, 4h, 6h, 8h, 12h, 24h, not simulated rainfall) after the application of imazapyr formulation Arsenal NA, 250 g ai ha-1 (1.0 L cp ha -1). The experiment had completely randomized design with four replications. Plants were evaluated at 7, 14, 21, 28 and 35 days after application (DAA), and the results submitted to analysis of variance by F test and treatment means compared by Tukey's test (p <0. 05). The occurrence of rainfall up to 6 hours after herbicide application, plants of P. stratiotes, negatively affected its efficiency and control; rainfall intervals over 8 hours had no effect in control. The occurrence of rainfall at all time intervals  did not affect the control of E. crassipes plants.  KEYWORDS: water hyacinth, waterlettuce, chemical control, phytotoxicity

Pre Treatment

Aquatic macrophytes are important components of aquatic habitats. However, the overgrowth of aquatic plants can cause severe problems for the management of bodies of water. As a result, these plants must be removed and disposed of as waste. However, the usage of this biomass as a substrate in biogas plants would appear to be more beneficial. The present work deals with the anaerobic digestion (AD) of macrophytes species that cause inconvenience to power generation at hydroelectric plant in Minas Gerais - Brazil. The study examines the following macrophytes species; Salvinia molest Oxycarium cubense, Eichhornia crassipes, Pistia stratiotes and Brachiaria. The experiments were carried out as stainless steel reactor with temperature, agitation and pressure control. As pre-treatment of macrophytes was used heat treatment at 120°C and pressure of 1.6 atm. The maximum methane content was 60% during 40 days digestion time, for Brachiaria of higher lignin content. The result obtained, mainly with Brachiaria demonstrates the efficiency of pre-treatment for the lignocellulosic samples.

Salvinia Molesta

Salvinia molesta is an aquatic weed having very high growth rate. The high abundance of this species biomass could be utilized as a source of alternative energy. This research was aimed to utilize S. molesta as a substrate for biogas production using batch system in order to reduce euthrofication effect in a lake. Cow manure was used as starter for anaerobic process because containing bacteria. Proximate test was conducted to analyze the chemical characteristics of the aquatic weed. Chemical oxygen demand, total solid, and total volatile suspended solid of weed and manure were analyzed according to the APHA 2012 method. Biogas composition was analyzed with gas chromatography. The results showed that the S. molesta contained high lignin content and low C:N ratio. Hydrolisis and acidification process occured very rapid, resulting in an increase of the weed and manure mixture COD. In the other hand, the decreased of COD removal was caused by the massal death of methanogenesis bacteria. The total solid and total volatile suspended solid content were not significantly decreased. Potential biogas production from S. molesta was 58.16 L.kg-1 with 318.29 mL.gram VS-1day-1 of methane production. This production value was still low or compared to that of cow manure which have been established as biogass materials and need modification to improve the biogas production.
