Abstract:

One of the alternatives to fulfil food needs, especially rice in Indonesia, is upland rice. Especially in the development of dry land and the development of cropping patterns on critical lands. Some of the obstacles that will be faced for upland rice cultivation are the risk of water stress, as well as the need for nutrients and soil organic matter. This research aims to see the effect of Application of Various Concentrations of Chitosan and Bacillus subtilis Biofertilisation on the Growth and Production of Upland Rice. The research was arranged based on a 2-factor factorial experiment with a Completely Randomised Block Design (CRBD) pattern, the first factor was Chitosan Application consisting of 3 levels, namely 0 (Control), 0.5, and 1.0 ml.L-1 The second factor is Baccilus subtilis biofertilisation with 3 levels of 1, 1.5, and 2 ml.L-1. Parameters observed included plant height (cm), number of tillers, flag leaf area (cm2), number of panicles per clump, and number of seeds per clump. Observation results showed that the application of chitosan 1.0 ml.L-1 gave better results on plant height increase with an average of 79.33 cm, flag leaf area (average 31.67 cm2) and Baccilus subtilis 2 ml.L-1), while the application of Baccilus subtilis 1ml.L-1 gave the best results on Yield per clump with an average of2273.2 per clump.

Abstract:

Piriformospora indica, classified as an Agaricomycetes fungus, has garnered significant interest due to its remarkable capacity to enhance plant growth, fortification, and resilience to stress factors. Its ability to inhabit various plant species stems from its direct influence on plant hormone signalling pathways. This colonisation stimulates increased root proliferation by generating indole-3-acetic acid, facilitating better nutrient absorption and ultimately leading to heightened crop yields. Furthermore, P. indica initiates resistance against fungal and viral threats while reinforcing the plant antioxidant defences, fortifying its resilience to stressors. It aids in successfully acclimating micro-propagated plants upon transplantation. It can establish complex symbiotic relationships, including tripartite symbiosis, which enhances the population dynamics of plant growth-promoting rhizobacteria. Overall, P. indica is a multifaceted facilitator of plant growth, a source of biofertilisation, a barrier against pests and diseases, a regulator of biological functions, and a promoter of overall plant development. Understanding the physiological and molecular mechanisms underlying the mutualistic interaction between P.indica and crop plants can provide valuable insights for enhancing crop protection and productivity, thereby contributing to the sustainability of agricultural practices.

Abstract:

Apple replant disease (ARD) impacts the economic yield of orchards by physiological and morphological suppression of apple trees on replanted soils. The complexity of replant disease caused by a plethora of biological interactions and physical properties of the soil requires complex management strategies to mitigate these effects. Based on expert recommendations, we selected two management strategies linked to agroecological principles of (a) organic fertilisation with a specific mulch composition (MDK) and (b) biofertilisation with arbuscular mycorrhizal and bacterial strains (AMFbac), applied by a composition of existing products. For both management strategies we provide a proof-of-concept, by pot and field experiments. Both treatments have the potential to mitigate ARD effects on plant vigour. ARD effect was fully mitigated by MDK treatment in the short-term (one year) and was mitigated by up to 29% after seven years of MDK treatment (long-term). MDK provides an additional substrate for root growth. AMFbac has the potential to mitigate ARD effects on plant vigour but with non-replicable plant-beneficial effects in its current form of application. Thereby our results show a principal potential to mitigate economic effects but not to overcome replant disease inducing effects. While the MDK treatment is found resource intensive but reliable, the AMFbac treatment was found more user-friendly.

Abstract:

En Côte d’Ivoire, la pratique des cultures continues ont entrainé la pauvreté des sols en éléments nutritifs. Pour y remédier, des espèces biofertilisantes en occurrence des légumineuses subligneuses susceptibles d’influer sur la disponibilité des éléments nutritifs du sol sont plantées dans les jachères pour la restauration de la fertilité. Cette étude sur le recensement et les caractérisations physicochimiques du sol et des légumineuses utilisées comme biofertilisants dans les jachères a été conduite à Daloa. La caractérisation chimique de ces végétaux réalisée sur la biomasse racinaire fraîche séchée au four à 65 ° C pendant 72 heures puis broyée et tamisée à une taille de 0,5 mm, a porté sur les compositions totales en N, P, K, Ca, Mg, C. Quant à la caractérisation du sol prélevé à 0-20 cm de profondeur, le pH, la taille des particules, l'azote total, le carbone organique, la capacité d'échange de cations, le P disponible et le K ont été analysés. Les prospections réalisées dans ces jachères ont permis de recenser six légumineuses comme culture principale. Ces légumineuses sont majoritairement lianescentes (50 %) contre 33 % des herbacées et 17 % d’arbustes. Les caractéristiques chimiques des racines ont montré une différence de variation de l’azote du témoin (13 g kg-1) à Mimosa invisa (28 g kg-1). Les concentrations en N, P, K ont été maximales chez toutes les espèces à l’exception de Mimosa invisa et Crotalaria retusa. Cependant, chez Mimosa invisa , les fortes concentrations de CEC (13,8 cmolc kg-1) et de C (27 g kg-1) ont été enregistrées. Les concentrations de phosphores (3,9 g kg-1) et de potassiums (53 g kg-1 de K) sont maximales respectivement chez Crotalaria goreensis et Crotalaria retusa. L’usage de ces légumineuses semble indispensable à la reconstitution de l’horizon humifère donc susceptible de restaurer la fertilité du sol et d’influencer la croissance des cultures non fixatrice d’azote.

ABSTRACT In Côte d'Ivoire, the practice of continuous cultivation has resulted in poor nutrient soils. To remedy this, biofertilizing species in the form of subligneous legumes likely to influence the availability of soil nutrients are planted in fallows to restore fertility. This study on the inventory and the physico-chemical characterization of the legume species used as biofertilizers in fallows was conducted in Daloa. The chemical characterization of these plants was carried out from fresh root biomass dried in an oven at 65 ° C for 72 hours then crushed and sieved to a size of 0.5 mm. The analyses related to the total compositions in N, P, K, Ca, Mg, and C. As for the characterization of the soil sampled at 0-20 cm depth, the pH, the size of the particles, Total nitrogen, the organic carbon, cation exchange capacity, available P and K were analyzed. Surveys carried out in these fallows have identified six legumes as the main crop. These legumes are mostly creeping (50%) compared to herbaceous (33%) and shrubs (17%). The chemical characteristics of the roots showed a difference in the variation of nitrogen from the control (13 g kg-1) to Mimosa invisa (28 g kg-1). Concentrations of N, P, and K were highest in all species except Mimosa invisa and Crotalaria retusa. However, in Mimosa invisa, high concentrations of CEC (13.8 cmolc kg-1) and C (27 g kg-1) were recorded. Similarly, the concentrations of phosphorus (3.9 g kg-1) and potassium (53 g kg-1 K) are maximum in Crotalaria goreensis and Crotalaria retusa respectively. The use of these legumes seems essential to the reconstruction of the humiferous horizon, therefore likely to restore soil fertility and influence the growth of crops that do not fix nitrogen.

Abstract:

Oak forests are facing multiple threats due to global change, with the introduction and expansion of invasive pathogens as one of the most detrimental. Here, we evaluated the use of soil biological fertiliser Biohumin® to improve the response of Quercus ilex L. to the soil-borne pathogen Phytophthora cinnamomi Rands by using one-year-old seedlings fertilised at 0, 12.5, and 25% concentrations of Biohumin® (v/v). Our hypothesis was that plant vigour and response to the pathogen would improve with Biohumin®. The effects of soil infestation and fertilisation were tested by assessing plant survival, growth, and physiology. The soil infested with P. cinnamomi negatively affected all the studied traits. We observed that a moderate concentration of Biohumin® (12.5%) increased plant survival. However, a high concentration (25%) reduced the survival compared with the control, probably as a result of the stress caused by both biotic (infection) and abiotic (soil toxicity) factors. Biohumin® at the highest concentration reduced the plant height-to-stem diameter ratio (H/D) and negatively affected plant biomass and physiological activity. Combined biofertilisation and infection induced synergistic negative effects in the leaf water potential compared with infection and fertilisation applied alone. A higher concentration of Biohumin® may favour pathogens more than plants. Further studies should explore the causes of the negative effect of the high concentration of Biohumin® observed here and evaluate if lower concentrations may benefit plant survival and physiology against soil pathogens.

Abstract:

L’objectif de cette étude est de proposer, par approche intégrée, une voie de gestion des déchets agro-industriels : halieutique, avicole, agrumicole. La valorisation énergétique du point de vue de la production de biogaz et aussi la valorisation du digestat qui en découle sont étudiées. Dix mixtures sont établies dans le cadre d’un plan simplexe-centroïde, leur digestion anaérobie dure environ 5000 min, suffisante pour atteindre la stabilité. L’évolution de plusieurs paramètres physico-chimiques tels que le pH, la conductivité, la matière sèche est déterminée. La conversion du carbone organique total (COT), le phosphore (P) et l’azote (NT) sont étudiés et modélisés par les surfaces d’isoréponses. Les contrôles microbiologiques pour vérifier l’hygiénisation des digestats sont menés. Le volume de biogaz produit pour les différents mélanges est mesuré en fonction du temps en utilisant la méthode du liquide déplacé. Finalement, le digestat est valorisé dans la fertilisation des sols agricoles, pour cela des tests de fertilisation sont ainsi conduits sur des cultures de poivrons (Capsicum annum). Les résultats montrent qu’il est possible de générer, après processus de digestion anaérobie optimale, un digestat, intéressant pour une application dans la fertilisation des sols agricoles, hygiénique par l’absence des micro-organismes d’altération, riche en azote, phosphore, potassium, caractérisé par un pH idéal pour la culture de poivrons.

Abstract:

Abstract Aquaculture effluent generation, an environmentally crucial process requires effective treatment. Simple methods like coagulation and flocculation are considered effective. In this study, chitosan from Black tiger shrimp, Penaeus monodon, was used to remove ammonia (NH3) and turbidity. Response surface methodology-optimised dosages (5.00, 12.50, and 20.00 mg·L−1), pH (5.00, 6.25, and 7.50), and settling times (5.00, 7.50, and 30.00 min) were applied. Water spinach, Ipomea aquatica, received an application for organic fertiliser after the nutrient status of the recovered floc was later determined. Results showed that at a dose of 16.25 mg·L−1, a pH of 7.5, and a settling time of 17.5 min, chitosan cleared 92.16% of the turbidity. After 30 min of settling, 84.42% of the NH3 was eliminated at 5 mg·L−1 and 7.5 pH. Both macronutrients (P, K, N, Mg, and Ca) and micronutrients (Co, Cu, Fe, Mn, Ni, Se, and Zn) are present in the newly discovered floc. Floc had safe low Pb and Ni levels. Plants treated with floc showed superior growth compared to those with commercial liquid fertiliser, confirming nutrient absorbability. Conclusively, this study provides an eco-friendly wastewater treatment method.

Abstract:

Abstract Background Endophytic bacteria possess a range of unique characteristics that enable them to successfully interact with their host and survive in adverse environments. This study employed in silico analysis to identify genes, from Bacillus sp. strain MHSD_37, with potential biotechnological applications. Results The strain presented several endophytic lifestyle genes which encode for motility, quorum sensing, stress response, desiccation tolerance and root colonisation. The presence of plant growth promoting genes such as those involved in nitrogen fixation, nitrate assimilation, siderophores synthesis, seed germination and promotion of root nodule symbionts, was detected. Strain MHSD_37 also possessed genes involved in insect virulence and evasion of defence system. The genome analysis also identified the presence of genes involved in heavy metal tolerance, xenobiotic resistance, and the synthesis of siderophores involved in heavy metal tolerance. Furthermore, LC-MS analysis of the excretome identified secondary metabolites with biological activities such as anti-cancer, antimicrobial and applications as surfactants. Conclusions Strain MHSD_37 thereby demonstrated potential biotechnological application in bioremediation, biofertilisation and biocontrol. Moreover, the strain presented genes encoding products with potential novel application in bio-nanotechnology and pharmaceuticals.
