Abstract Applying organic waste and inorganic additives during composting can be an effective and easy-to-control strategy for optimizing humification, maturation, and the availability of essential mineral elements in compost. In this respect, this study aims to evaluate the effect of organic (olive-mill waste and horse manure) and inorganic (phosphogypsum) additives on the evolution of maturity indices, aromatic compounds, and nutrient availability during composting. Four mixtures [horse manure + green waste (M1), olive-mill + green waste (M2), sewage-sludge + phos-phogypsum + green waste (M3), and green waste (M4)] were carried out. Physicochemical (temperature, pH, phosphorus, nitrogen, and… More >

Abstract Quinoa (Chenopodium quinoa) has recently gained popularity as a pseudo-cereal cultivated in various countries due to the nutritional and antioxidant benefits of its seeds, and its capacity to persist in water-stressed environments. Our study aimed to assess the effects of native arbuscular mycorrhizal fungi (AMF) and local organic amendments on the metabolic responses and antioxidant activity of quinoa seeds under water-stressed conditions. To this end, quinoa plants were grown in soils inoculated with an indigenous mycorrhizal consortium AMF and amended with two types of compost from horse manure (HM) and green waste (GW) under two water… More >

Abstract This study assesses the effectiveness of using arbuscular mycorrhizal fungi (M) and compost applied alone or in combination (vs. conventional chemical fertilizer application (NPK)) on tomato resistance to vascular wilt caused by Verticillium dahliae. In this study, ten treatments were applied: (1) Control (2) M: Rhizophagus irregularis (3) C: Compost (4) MC: The combination of M and compost (5) NPK: conventional chemical fertilizer (6) V: plants infected with V. dahliae (7) MV: plants infected with a conidial suspension of V. dahliae and M, (8) CV: The combination of compost and V. dahliae, (9) MCV: The combination of M, compost and V. dahliae,… More >

Abstract Due to the unpredictable climate change, drought stress is being considered as one of the major threats to crop production. Wheat (Triticum aestivum L. cv. BARI Gom-26) being a dry season crop frequently faces scarcity of water and results in a lower yield. Therefore, this experiment aims to explore the role of different organic amendments (OAs) in mitigating drought stress-induced damage. The pot experiment consisted of different organic amendments viz. compost, vermicompost and poultry manure @0.09 kg m⁻² soil, biochar @2.5% w/w soil and chitosan @1% w/w soil which was imposed on the plants grown under both… More >

Abstract The safe and efficient disposal and utilization of sludge are major issues to be solved in solid waste treatment and environmental protection due to the complex characteristics of sludge and the low rate of innocuous treatments. Composting is a process of decomposing organic matter and transformed low-molecular organic acids into high-molecular humus substances under the action of microorganisms. Although land-use after composting has become an important direction for sludge treatment, heavy metal pollution is still the bottleneck problem restricting land use of sludge compost. Adding zeolite, hydroxyapatite, and other conditioning agents to the composting process More >

Abstract Vermicompost is an organic fertilizer contains multiple nutrient elements. However, the application of vermicompost in fragrant rice production is rarely reported. In order to study the effects of vermicompost application on fragrant rice (Oryza sativa L.) seedling performances, present study was conducted with two fragrant rice cultivars and four vermicompost rate treatments (0 (CK), 2.5 (Wo1), 5.0 (Wo2) and 10.0 (Wo3) g kg⁻¹ ). The results showed that vermicompost treatments significantly increased dry weight of fragrant rice seedling by 8.31–32.56% compared with CK. 21.10–59.13% higher net photosynthetic rates and 10.66–59.16% higher chlorophyll contents (chlorophyll a, chlorophyll b More >

Abstract The aim of this investigation was to analyze the effect of vermicompost and phosphate rock on plant growth and biochemical responses of Moringa oleifera exposed to water deficit and waterlogging conditions. Treatments included 152 g of vermicompost (V) and 1.3 g of phosphate rock (PR) added to each cultivation bag. Control was prepared with 2.3 g of urea. All treatments were irrigated under different watering conditions [water deficit: irrigated at 20% water holding capacity (WHC); control (40% WHC) and waterlogging (60% WHC)]. The overall average in plant height was 90, 86 and 68 cm, whereas chlorophyll… More >

Abstract It is documented that vermicompost increases germination and productivity of crops, but little is known of its effect on plant physiological responses under soil water deficit. The aim of this study was to analyze the effect of vermicompost and irrigation interruption on stomatal conductance, gas exchange, and yield of common bean cultivars (drought tolerant -cv. 92 and drought susceptible-cv. 122). Plants were cultivated in unamended soil or soil amended with 1.5 and 3% of vermicompost, with irrigation during the whole cycle but irrigation interruption at the flowering stage. Changes in soil moisture, stomatal conductance (g_s), transpiration… More >

Abstract The Streptomyces genus comprises a large and diverse group of bacteria, many of which are commercially exploited for the production of antibiotics and lytic enzymes. The thermophilic species are less studied than the predominant mesophilic species. However, the first ones are a potential source of thermostable bioactive products and enzymes with novel properties. In this study, two selected thermophilic streptomycetes were identified and their chitinolytic activities were evaluated. The identification of these two isolates was performed by microscopic morphology, partial 16S rDNA sequences, and its phylogenetic analysis. To study the chitinolytic activities of these isolates, the… More >

Abstract The aim of this study was to establish the dynamics of growth and allocation of photosynthates in squash (Cucurbita pepo L.) cultivated in a semiarid region under greenhouse conditions and in an organic substrate. Squash seeds were sown in two substrates (one mineral and other organic). The first consisted of a mixture of sand and pumice on a volume basis, while the organic consisted of sand and pumice mixed with vermicompost, both in plastic pots. The substrates were for two treatments [Inorganic (IT) and Organic Treatment (OT)] with sixteen repetitions on a completely randomized design. After… More >
