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 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 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 >

Abstract In the floriculture region of Tenancingo in the State of Mexico, the application of stabilized organic matter, such as vermicompost and leachates, contributes to improve the quality of the soil and plant nutrition. However, it is important to know the chemical composition of a vermicompost and the mineralization process. This is because the amount and speed of nutrient release which will be available to the crop will depend on that knowledge. The objective of the study was to evaluate the effect of the application of a vermicompost and leachates on various quantitative variables of Solidago x… More >

Abstract The objective of this work was to analyze the impact of a vermicompost treatment on anatomical and physiological modifications related to assimilate partitioning and growth in lettuce seedlings. The results showed that vermicompost increased growth, which was most likely due to an increased activity of the ground meristem of the leaf blade. A greater height and number of chlorenchyma layers were observed in the leaf blade. This was related to an increase in the photosynthetic activity, expressed by an increase in the net assimilation rate. Vermicompost also showed an effect at the procambium level, producing More >

Abstract The objectives of this study were to (1) isolate and identify pathogenic fungi from vegetative material with wilt symptoms in tomato plantations belonging to the Cienega of Chapala, Michoacán, Mexico, and (2) determine the antagonistic capacity of Trichoderma sp. and Aspergillus spp. isolated from chicken-manure vermicompost. Pathogens were isolated by means of a completely randomized sampling in 6 locations; 9 plantations were inspected and 45 plants with symptoms of the disease were selected. Portions of root and stem were disinfected and placed on potato-dextroseagar acidified (PDA). Antagonists isolation was made from a dilution of chicken-manure vermicompost… More >

Abstract In this paper, the effects of four vermicomposts are analyzed on a variety of growth and development parameters of Digitaria eriantha cv. Mejorada INTA. The vermicomposts used originated from cow, horse, goat and hen feaces combined with pure soil in the following proportions: T1: 0% worm humus + 100% soil; T2: 50% worm humus + 50% soil, and T3: 100% worm humus + 0% soil. Digitaria eriantha seeds were sown in trays which were kept under controlled light and moisture conditions. After the third week of treatment, the number of germinated seeds, and both leaf and More >

Abstract Rhizoctonia solani damping-off and root rot diseases are frequent in impatiens crops in Buenos Aires. Their control is based in fungicide use. In a sustainable nursery production, beneficial microorganisms that develop in organic amendments may suppress diseases and promote plant growth. The aim of this work was to evaluate the effect of different proportions of vermicompost on the growth and health of patience-plant (Impatiens wallerana). The experiment was carried out in a polyethylene greenhouse. Treatments were defined as follows: infested substrate, substrate, sterilized substrate, vermicompost, and vermicompost mixed with infested substrate at 75, 50 and 25% by More >
