“…Other studies showed that organic farming was also superior in the content of total nitrogen, NH 4 + , soil pH, microbial carbon and particulate organic matter carbon [7], [8], [9], [10]. The addition of N fertilizer to organic fertilization, however, did not provide an effect of total soil nitrogen of Ultisol as reported by [11].…”

Solid organic fertilization in organic farming practices should be supplemented with liquid organic fertilizer to accelerate the availability of plant nutrients. The study aimed to determine performance and major nutrient uptake by sweet corn following application of vermicompost supplemented with liquid organic fertilizer (LOF) and to find out combined vermicompost and liquid organic fertilizer for sweet corn production. The experiment was conducted at CAPS Research Station (1054 m above sea level) from April to June 2016, arranged in split plot design with 5 rates of vermicompost as the main plot and 5 rates of LOF as the subplot. Rates of vermicompost comprised 5, 10, 15, 20, and 25 Mg ha-1 , while LOF rates consisted of control, 25, 50, 75, and 100% (initial concentration). Treatment combination was replicated 3 times. Root application of LOF was carried out every week at 2-8 weeks after planting (WAP) with total volume of 950 ml plant-1. Result pointed out that vermicompost pronouncedly raised nitrogen (N), phosphorus (P) and potassium (K) uptakes and linearly enhanced growth and yield of sweet corn, indicated by plant height, plant leaf area, shoot fresh and dry weight, weight of husked and unhusked ears, diameter of ear, and weight of husked ear per plot but length of ear. The addition of LOF had a similar effect on major nutrient uptake, growth, and yield of sweet corn. Vermicompost at the rate of 25 Mg ha-1 supplemented with 100% LOF provided greatest growth and yield, suggesting that the fertilizer combination was the most effective complementary organic fertilization for sweet corn production in the organic farming system.

Red lettuce (Lactuca sativa L.) is widely consumed for its health benefits. With the a growing global population and limited land resources, there is a need to increase the nutritional content and bioactive compounds of vegetables or fruits. This research aims to increase the growth, productivity, and the content of anthocyanin, vitamin C and flavonoids in red lettuce leaves through exposure to magnetic fields during seeding. The research utilized red lettuce seeds as the research sample. Exposure was carried out using an alternating magnetic field (MF) with an effective magnetic flux density (MFD) of 0.4 mT, a frequency range of 25-125 Hz, and a dailyexposure time of 15 minutes. The treatment of each sample group was repeated for five days. The results showed that exposure to a MF with a frequency of 75 Hz resulted in optimum growth and weight, an increase of 65.15% and 60.18%, respectively. The optimum anthocyanin, vitamin C, and flavonoid content were obtained at an exposure to a frequency of 100 Hz, an increase of 22.52%, 40.70%, and 32.50%, respectively. Exposure to seeds uses an alternating MF; frequency is an important parameter for producing optimum enhancement.

Contexto: El incremento poblacional y la demanda de alimentos generan mayores demandas en la productividad, lo que estimula el uso de fertilizantes inorgánicos como una práctica habitual en los sistemas agrícolas, generando potenciales riesgos de contaminación por lixiviación de nutrientes, además de altos costos que pueden afectar la rentabilidad de los sistemas productivos. La aplicación de materiales orgánicos procedentes del compostaje de sustratos orgánicos es una fuente de fertilización común en sistemas de producción limpia, orgánica y con menores costos. Método: En este estudio se evaluó el efecto de la fertilización con una enmienda orgánica (EO) procedente del compostaje de biorresiduos de origen municipal (BOM) mezclados con cachaza, sobre la mineralización del nitrógeno (Nmineralizado) de un suelo ácido, evaluando seis tratamientos (tres controles: T1: 100% suelo; T2: 100% EO; T3: 100% urea-fertilización inorgánica: F) y 3 proporciones EO ( %): F ( %) (T4: 50-50, T5: 75-25, T6: 25-75) en un periodo de incubación de 16 semanas. Resultados: Se aplicaron los modelos de mineralización de Stanford y Smith, Broadbent, Lineal y Polinomial-Exponencial, encontrándose que T4 permitió alcanzar un aporte de Nmineralizado (12.546,39 mg/kg), el cual es un valor muy cercano al resultado obtenido por fertilización inorgánica (T3: 13.931,05 mg/kg); los modelos de Broadbent (R2 >0,98) y Lineal (R2 >0,90) alcanzaron los mejores ajustes. Conclusiones: Esta estrategia de reemplazo parcial del fertilizante inorgánico puede lograr hasta un 50% de reemplazo del fertilizante inorgánico.
