“…In general, the Mn concentration was on average almost twice as much in leaf (268 mg•kg -1 ) than in root (141 mg•kg -1 ), while the concentration in stem (20 mg•kg -1 ) was 14 times less than in leaf. The same behavior could be observed in the study carried out by Lavres-Junior et al (2012) since the Mn was more concentrated in leaf than root and stem. The application of biosolids increased the concentration in the three organs more than the application of AS (Table 4).…”

“…Applying biosolids significantly increased the Zn concentration in the three organs evaluated; the higher the application rate, the greater the Zn concentration in root and stem, but not in the leaves (Table 4). Lavres-Junior et al (2012) observed that Zn was concentrated to a greater extent in root (62.3 mg•kg -1 ) and leaf (59.2 mg•kg -1 ). In the present study, the average concentration in leaf was 73 mg•kg -1 .…”

“…Es probable que la higuerilla requiera poca cantidad de Cu y por eso limita su transporte desde raíz y tallos a las hojas. Aun así, los resultados concuerdan con lo reportado por Lavres Junior et al (2012), quienes encontraron concentraciones en hojas de higuerilla de 2.7 a 5.2 mg•kg -1 , cuando el cultivo fue en soluciones nutritivas con diferentes concentraciones de Cu.…”

Concentración de elementos menores en plantas de higuerilla (Ricinus communis L.) que crecieron en suelo fertilizado con biosólidos

Los suelos alcalinos y calcáreos, típicos de las zonas áridas, limitan la disponibilidad de micronutrientes en el suelo para algunos cultivos. El objetivo del presente trabajo fue evaluar los contenidos de elementos menores en suelo y plantas de higuerilla cuando se usaron sulfato de amonio y dos tipos de biosólidos como fertilizantes. Los tratamientos se definieron al considerar tres fuentes (fertilizantes) y tres dosis de N, así como un testigo (sin fertilización). Las fuentes de N fueron sulfato de amonio (SA), biosólidos de plantas de tratamiento de agua residual con lagunas de oxidación (BLO) y con lodos activados (BLA). Las dosis de N fueron de 0 (testigo), 134, 200 y 260 kg∙ha-1. El diseño experimental fue bloques al azar con cuatro repeticiones. El rendimiento de materia seca y el contenido de aceite en semillas se incrementaron al aumentar las dosis de N. Las concentraciones mayores de Cu y Fe en el suelo después de la cosecha correspondieron a los tratamientos con BLO, con medias de 0.98 mg∙kg-1 de Cu y 5.20 mg∙kg-1 de Fe. Los resultados indican que los biosólidos utilizados en el presente trabajo aportaron los micronutrientes necesarios para un desarrollo adecuado de plantas de higuerilla, sin riesgo de toxicidad y contaminación.

“…B is the second most demanded micronutrient in cowpea (Ara ujo et al, 1984;Oliveira and Dantas, 1984), and its deficiency limits crop productivity. This B deficiency may induce changes in the cell wall and cause middle lamella thickening, chloroplast deformation in castor (Ricinus communis) (Lavres J unior et al, 2012), and starch grain accumulation in cowpea (Vigna unguiculata) leaf chloroplasts (Inbaraj and Muthuchelian, 2011).…”

Additional index words. Vigna unguiculata, plant nutrition, crop quality, nutrient management, sorbitolAbstract. This study aimed to evaluate the effects of boron (B) omission on cowpea nutrition and to compare the impact of foliar B fertilization with and without sorbitol on cowpea growth, nutritional status, and B uptake. Two trials using a completely randomized experimental design were conducted. During the first experiment, nutrient solution was provided without B (LB) and with B (+B) in 10 replicates. During the second experiment, a 5 3 2 factorial treatment scheme was used. Five B concentrations (0, 1.25, 2.5, 3.75, and 5.0 g · L L1 ) were administered foliarly in the form of boric acid with or without sorbitol (500 mmol · L L1 ) in four replicates. B omission symptoms, root growth, plant organ dry mass and B content, and grain yield were evaluated. B omission induced greater losses in reproductive organ and root growth than in leaf and stem production. It also caused deformation of the middle lamella and accumulation of starch in the chloroplasts. Foliar applications of 2.6 to 2.9 g · L L1 B improved cowpea production. The addition of sorbitol did not enhance plant growth. However, it increased B absorption in the vegetative parts of the plant but did not enhance seed production.
