“…The effects can be positive or negative depending on how the minerals are utilised or immobilised. This can be influenced by microbial biodiversity and the addition of organic material, which in combination affect plant productivity [32].…”

Research objective: The objective of this work was to evaluate the properties and effect of certain organic fertilizers that can be used in organic farming in comparison with fertilizers of inorganic origin on Abelmoschus esculenthus plants. In addition, the interactions that can develop with microorganisms in the rhizosphere and the possible beneficial effects on transplant stress, nutrient uptake by roots and reduction of plant mortality were investigated. Materials and Methods: The experiments, which began in May 2022, were conducted in the greenhouses of CREA-OF in Pescia on plants placed in pots 12 cm in diameter and on which fertilizers of organic and inorganic origin were evaluated. In September 2022, plant height, number of leaves, leaf surface area, vegetative weight, root volume, root length, seeds per plant, number, weight, girth and length of pods, total substrate bacteria, substrate pH and number of dead plants were analysed. Results and Discussion: The experiment showed that the application of organic nitrogen and potassium fertilizers can significantly improve the quality and yield of Abelmoschus esculenthus plants. In general, a significant increase in height and vegetative and root growth of the plants was observed, especially in nitrogen and potassium synthesis, with an improvement also in the number of fruits and seeds per plant. Plant mortality also decreased significantly compared to the control with synthetic fertilizers, and microbial colonisation of the substrate increased, which probably affected the plants by influencing both vegetative and root growth and defence against biotic stressors. Conclusions: Organic fertiliser trials showed that these products can significantly improve plant growth by positively affecting the soil microbial component. This is an additional opportunity, especially for those farmers who not only seek to reduce the use of synthetic fertilizers, but also want to use sustainable techniques that better preserve plants and soils, while guaranteeing the production of quality products.

“…This fruit crop has been gaining commercial interest around the world, and under intensive cultivation under soilless and glasshouse culture yields reach from 81 t ha -1 [6] up to 109.5 t ha -1 [7]. Under this production system and other, more conventional systems [8,9], organic or combined fertilization is required to enhance fig productivity, regardless of plant guiding, pruning, pest, disease and weed control, irrigation [10], and plant nutrition [3,9,11,12]. The seasonal variation of macro-and micronutrients in high-and low-vigor fig tree orchards in California was studied [11], but no production values were offered.…”

Aims: The effect of a complete NPK matrix on leaf nutrient concentrations and dry biomass of ‘Black Mission’ fig plant organs was tested under an intensive culture system and protected environment. Study Design: A randomized complete block design with four blocks was employed. Place and Duration of Study: The experiment was conducted from April to November 2016 at the Campo Experimental La Laguna, located in Matamoros, Coahuila, Mexico. This research station belongs to the Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP) of Mexico. The experiment was set up under a macro tunnel equipped with a shade mesh with 50% sunlight attenuation. Methodology: Two-year-old fig plants (cv. ‘Black Mission’) previously propagated from stem cuttings were used. There were three application rates each for N (0, 80, and 160 kg ha-1), P (0, 40 and 80 kg ha-1), and K (0, 80, and 160 kg ha-1) arranged in a balanced factorial matrix of 27 treatments. After harvest, leaf samples were collected to determine nutrient concentrations and they were split into roots, shoots, leaves, and fruit Results: The greatest total dry biomass was produced by the interaction of 80 kg ha-1 N and 40 kg ha-1 P and yielded the following leaf nutrient concentrations (mean ± SD): N 2.9 ± 0.3%, P 0.11 ± 0.01%, K 2.1 ± 0.4%, Ca 1.4 ± 0.7%, Mg 0.34 ± 0.03%, Fe 166.4 ± 49.5 mg kg-1, Cu 6.3 ± 1.7 mg kg-1, Mn 83.3 ± 20.9 mg kg-1, and Zn 22. 6 ± 3.8 mg kg-1. Application of 80 kg ha-1 N and 40 kg ha-1 P could be suggested for commercial fig production. Conclusion: Application of 80 kg ha-1 N and 40 kg ha-1 P could be tested under similar commercial production systems; however, the addition of supplemental K deserves further study.

“…Azeez, Averbeke e Okorogbona (2010) consideram limitado o conhecimento acerca da resposta das culturas à aplicação de diferentes tipos de esterco, embora seu uso seja bastante difundido, porém, foram observados aumentos da produção de figueiras (LEONEL; TECCHIO, 2009), de milho (SAMPAIO et al, 2007 e de milheto (NICOLAU SOBRINHO et al, 2009). O efeito do esterco foi maior do que o de adubo industrial em milho ; suficiente para fornecer nutrientes, na ausência de adubo industrial, para produção de mudas de mamoeiro (CANESIN; CORRÊA, 2006) e para o fornecimento de N para alface Neste trabalho o termo "adubo industrial" refere-se aos adubos sintéticos, fontes de N, P e K na forma mineral e orgânica, produzidos industrialmente.…”
