“…In addition, correlation between the time pass after liming with leaf manganese levels was found. Two chemical forms are mostly used for the correction of Mn deficiency of fruit trees, the inorganic (MnSO 4 ) and organic (Mn EDTA) forms (Papadakis et al, 2005). According to results of some experiments on apple trees (Thalheimer and Paoli, 2002) and orange trees (Papadakis et al, 2005), foliar application of manganese sulfate was more effective than manganese chelate in increasing leaf Mn concentrations.…”

Broschat (1991) Balakrishnan et al (1996) reported that foliar application of 0.25% each of zinc sulfate, manganese sulfate and iron sulfate combined with 0.15% boric acid, significantly increased fruit yield and juice content of pomegranate fruit.…”

Effects of foliar sprays of zinc and manganese sulfates on the fruit yield and quality as well as leaf nutrients concentration of pomegranate were studied during 2010 growing season in an orchard with a soil pH of 7.5 and EC of 5.2 (dS m -1 ). Zinc and manganese sulfates were applied two times at the rate of 0, 0.3 and 0.6 percent under a factorial design on the base of completely randomized blocks. Mn sprays had positive significant effects on the fruit yield, the aril/peel ratio, TSS, weight of 100 arils, juice content of arils, anthocyanin index, fruit diameter and leaf area. Zn effects were also significant for TSS, TSS/TA ratio, juice content of arils and leaf area. Foliar spray of Mn significantly increased Mn and N but decreased Zn and Cu concentrations in leaves. Foliar sprays of Zn significantly increased Zn but decreased Mn and P concentrations in the leaves. According to the results, the suitable combination of these two micronutrients for studied characters of pomegranate under prevailing conditions was foliar spray of 0.6% MnSO 4 and 0.3% ZnSO 4 .

“…Manganese is available to the plant in acidic and waterlogged soils (Shi et al 2005); deficiency of Mn occurs in neutral and alkaline reaction soils. The most rapid and efficient way to prevent and/or correct Mn deficiency is foliar application of solutions containing inorganic or organic Mn (Papadakis et al 2005). Silicon (Si) is involved in enhancing disease resistance of plants.…”

The aim of the study was to assess whether an extra fertilization with manganese, commercial fertilizer Alkalin (N, K and Si), and combined treatment (manganese + Alkalin) affect the chemical composition of chokeberry fruits (Aronia melanocarpa (Michx) Elliot), especially sugar content and the quantity and profile of phenolics. Dry weight, soluble solids, titratable acidity, total sugar, reducing sugar, sucrose, vitamin C, total polyphenol (gallic acid equivalents); 2, 2-diphenyl-1-picrylhydrazyl radical scavenging activity; and phenolics profile were measured from the fruits harvested from different treatments. Chokeberries treated with manganese showed high content of non-identified phenolic acids [101.15 mg per 100 g fresh weight (FW), these compounds were not detected in fruit treated with Alkalin and manganese + Alkalin], and the highest content of cyanidin glycosides (813.75 mg per 100 g FW). The fruits treated with Alkalin displayed the highest content of quercetin derivatives (40.88 mg per 100 g FW) and eriodictyol 7-glucuronide (26.43 mg per 100g FW). Chokeberries in control treatments had the highest content of dry weight (30.76% FW), soluble solids (24.1% FW), total sugar (20.92% FW), vitamin C (8.4 mg 100 g -1 FW), total polyphenol (2377.1 mg gallic acid equivalents per 100 g FW), the highest 2, 2-diphenyl-1-picrylhydrazyl radical % inhibition (38.1%), highest content of chlorogenic acids (210.38 mg per 100 g FW), (-)epicatechin (32.18 mg per 100 g FW) and the highest degree of procyanidin polimerization (59). The results indicate that applied fertilization exerted differential influence on chemical composition of aronia fruits.

“…Las aplicaciones de Mn suelen realizarse en banda subsuperficial y al follaje, siendo el sulfato de manganeso (MnSO 4 ) la fuente más empleada (Papadakis et al, 2005). La baja dis-ponibilidad del Mn para las plantas se debe en gran medida a la formación de óxidos insolubles Mn III y Mn IV , constituyendo la fracción dominante del Mn en los suelos (Binner y Schenk, 2013).…”

“…En otros casos, para suelos con bajo contenido nativo del Mn, calcáreos y orgánicos se recomienda fertilizaciones foliares con quelatos de Mn y así reducir su inmovilización (Lucena, 2009). La fuente orgánica (Mn-EDTA) puede ser ineficiente después de ser aplicado al suelo porque el Mn es rápidamente sustituido en el quelato por Fe, Cu o Zn (Papadakis et al, 2005).…”

Foto: A.I. Prato RESUMENEn la agricultura orgánica de hortalizas, el uso de sustratos a base de vermicompost es una alternativa cada vez con mayor aceptación. La fertilización eficiente de manganeso (Mn) requiere manejos agronómicos diferenciados dadas las complejas variables de absorción y disponibilidad de este micronutriente en el suelo. Nuevos productos de fertilizantes deben ser estudiados extensamente. Se evaluó en condiciones de invernadero, el efecto de la fertilización de Mn en espinaca, híbrido Panther, empleando dos fuentes -sulfato y gluconato-en aplicación líquida edáfica y foliar, a una concentración de 50 mg L -1 (1,5 kg ha -¹), y sin la aplicación del micronutriente. La fertilización fue parcializada en 10 aplicaciones. Plántulas con 15 días desde germinación fueron trasplantadas en materas de 2 L en un sustrato vermicompost. Desde los 12 días después de iniciar los tratamientos, las plantas evidenciaron efecto según la fuente y método de aplicación para la masa seca aérea y área foliar. Al final del periodo de estudio, la fuente de MnSO 4 edáfico presentó la mejor respuesta, con mayor acumulación de masa seca aérea, número de hojas y altura planta frente a las plantas control, 86,7; 56,8 y 28,0%, respectivamente. Tanto la aplicación foliar y edáfica del gluconato de Mn resultaron en valores próximos, sin síntomas visibles de toxicidad a la dosis evaluada. Este producto podría llegar a ser una opción viable de fertilización de Mn en espinaca. Additional key words: complex micronutrient, fertilization, dry mass, plant height. Fecha de recepción: 21-07-2014Aprobado para publicación: 10-11-2014 ABSTRACTIn the organic farming of vegetables, the use of vermicompost-based substrates is an alternative with increasing acceptance. Efficient fertilization with manganese (Mn) requires different agricultural management variables given the complex variables of absorption and availability of this micronutrient in the soil. New fertilizer products must be studied extensively. The effects of Mn fertilization on spinach were evaluated under greenhouse conditions using two sources -sulfate and gluconate -in liquid foliar and soil applications at a concentration of 50 mg L -1 (1.5 kg ha -1 ) and without the application of this micronutrient. The fertilization was separated into ten applications. Fifteen days after germination, seedlings were transplanted into 2 L pots filled with a vermicompost substrate. Starting at 12 days after the beginning of the treatment, the plants showed effects that depended on the source and method of the application for the aerial dry mass and leaf area. By the end of the study period, the edaphic source of MnSO 4 presented the best response with a higher dry matter, number of leav...
