“…The results of the three years of testing in the present study suggest that exclusive fertilization with tomato plant debris produces a yield and crop quality similar to that obtained with traditional inorganic manure in production cycles of 215 DAT. Several authors have reported a similar result when they analyzed the production of tomato crops with only organic fertilizer (compost, bone meal, blood or hoof meal, chicken, sheep or turkey manure, and plant debris) versus conventional fertilization, both with or without using pre-transplant solarization and conventional fertilization [ 61 , 62 , 63 , 64 , 65 , 66 ] to obtain a tomato fruit of similar quality [ 62 , 63 , 64 ]. Some investigations have also reported decreases in the production of a bell pepper crop nourished with tomato plant debris and compost compared to the conventional crop.…”

Greenhouse agriculture typically generates large amounts of waste with plant residue (agricultural biomass) being the most abundant. This residue is generated on a seasonal basis, which complicates the external management of the material. Recently, the European Union (EU) has been implementing a policy based on sustainability through the circular economy that seeks to minimize waste generation. The effect of reusing 3.5 kg·m−2 tomato plants from the previous season as the only fertilizer versus no fertilization and inorganic fertilization in 215-day tomato cycles after transplanting was studied in this trial. The study was carried out during three seasons in greenhouse agriculture in Almeria (Spain) with the repeated use of the solarization technique. The plant debris had similar production results during two of the three seasons and fruit quality parameters were similar to inorganic fertilization. In addition, some physicochemical variables improved and the biological depressive effect of solarization was mitigated. The results suggest that the reuse of the tomato plant debris as the only fertilizer could be an alternative to conventional fertilization under the conditions tested.

“…De las propiedades del fruto, se ha reportado que, en la producción orgánica, los frutos de tomate contienen cantidades más altas de SST en comparación con tomates cultivados convencionalmente (Bilalis et al, 2018;Rickman-Pieper y Barrett, 2008), pero no todos los estudios han coincidido en este aspecto (Polat, Demir y Erler, 2010;Guajardo et al, 2018). Según los resultados, los frutos de las plantas tratadas orgánicamente obtuvieron 11.20% más de SST que los frutos con el tratamiento inorgánico.…”

En el ámbito de la agricultura sostenible, el uso de fertilizantes orgánicos es una opción viable ante el impacto ambiental causado por los fertilizantes convencionales. El objetivo de este trabajo fue evaluar el efecto de abonos orgánicos como fuente de N sobre el crecimiento, rendimiento, calidad y atributos morfológicos en frutos de tomates uva. Se evaluaron siete tratamientos de fertilización, los cuales consistieron de una solución nutritiva inorgánica (solución Steiner) y diferentes mezclas de varios fertilizantes nitrogenados de origen animal certificados por OMRI a una concentración del 100 y 120%. Los resultados mostraron que los tratamientos orgánicos T5 y T6 presentaron similar crecimiento que el tratamiento convencional (T7). El índice SPAD fue 13.8% mayor en los tratamientos orgánicos respecto al tratamiento inorgánico T7. En los parámetros de producción de fruto, el tratamiento orgánico T5 asemejó al tratamiento convencional en el número de frutos por racimo, pero en peso fresco de fruto, rendimiento y diámetro longitudinal el tratamiento convencional superó a los tratamientos orgánicos por un 21, 31.6 y 5.8%; mientras que, el diámetro transversal fue similar en los tratamientos T1 y T7. La firmeza de fruto fue mayor en los tratamientos orgánicos T1 y T4, superando al tratamiento inorgánico por 10.3 y 6%, respectivamente. Los sólidos solubles totales fueron mayores en el tratamiento orgánico T4, superando al tratamiento inorgánico T7 por un 18%. El tratamiento inorgánico T7 presentó mayores valores en la mayoría de los atributos morfológicos, aunque los efectos fueron estadísticamente similares a los de T3, T5 y T6.

“…The release of nutrients in organic fertilizer is slower than inorganic fertilizer because they must pass through a decomposition process first (Guajardo-Ríos et al, 2018). Therefore, combining the two is needed to create good soil physical, chemical and biological properties that will produce maximum plant growth and yields.…”

The nutrients of plants and the physical condition of the soil must both be considered to increase corn productivity. The continuous use of inorganic fertilizer without manures will cause a decrease in the physical properties of the soil. Therefore, this study aims to obtain doses of organic fertilizer from cow manure and inorganic fertilizers namely urea, KCl and SP-36 that will give the best effect on the physical properties of Alfisols, growth and yield of hybrid corn. The experiment was carried out using the randomized complete block design (RCBD) with two factors namely organic and inorganic fertilizers. Each factor was given at four dosages: 1, ¾, ½ and ¼ of the standard dose each with three replications. Observation parameters include bulk and particle density, soil porosity, aggregate stability, root volume and fresh weight, plant height, as well as the weight of corn with and without husks. The results showed that organic and inorganic fertilizers significantly affected bulk density, soil porosity, aggregate stability, root fresh weight, root volume, as well as the weight of corn with and without husks. Additionally, treatment with 7.5 to 10 tons of organic fertilizer as well as ¼, ¾ and 1 dose of inorganic fertilizers produced the best effect on soil physical properties of Alfisols, growth and yield of hybrid corn, while the lowest results were obtained in the control treatment. This indicates that organic treatment can reduce the use of inorganic fertilizers between ¼ to ¾ of the standard dose.
