“…The need for Mg in the stages of plant growth varies between 1.5-3.5 g.kg -1 (Hawkesford et al, 2012). The Mg contents of PM1, PM2, and SV were higher than the values considered ideal for plant growth.…”

A B S T R A C TThe green manure, through the simultaneous sowing of different species, can be a strategy to mitigate the environmental impact due to the use of fertilizers in irrigated environments in the Brazilian semi-arid. This study aimed to evaluate the dry matter production and the nutrients concentration and accumulation by phytomass of two types of plant mixture and natural vegetation cultivated between lines of a mango orchard, in two soil systems management, during five production cycles. The experiment was conducted in a complete randomized block design with four replications and treatments arranged in subdivided plots scheme. The plots consisted of two soil management systems (tillage and no-tillage), and the subplots consisted of 3 types of green manures: plant mixture 1 (PM1); plant mixture 2 (PM2) and spontaneous vegetation (SV). The dry matter, contents, and accumulation of N, P, K, Ca, Mg and S were evaluated. Plant mixture, independent of their composition, produced higher amounts of dry phytomass compared with natural vegetation and, consequently, accumulated higher amounts of nutrients. The N and P contents were lower in the phytomass of the spontaneous vegetation and the plant mixture with a predominance of grasses and oilseeds, respectively, in the tillage systems. The Ca contents were higher in the plant mixture with a predominance of grasses and oilseeds (PM2), and Mg in the plant mixture with a predominance of legumes (PM1) and the spontaneous vegetation (SV).

“…The amount of Ca required for monocotyledonous is lower than for dicotyledons (Hawkesford et al, 2012). Thus, in the present study, to interpret the effect of soil management and the types of plant mixture, it is important to perform an analysis of the contents and amounts of Ca accumulated by each species that compose them.…”

“…Una def iciencia de P se caracteriza por el desarrollo de una pigmentación roja en las hojas por acumulación de antocianinas, una limitada expansión de la superf icie foliar, y un limitado desarrollo de la parte aérea, mientras que el desarrollo de las raíces es menos afectado (Hawskesford et al, 2012). En el presente estudio no se detectaron síntomas de pigmentación ni reducción en el tamaño de las hojas, sin embargo, la producción de biomasa, el rendimiento de fruto (Cuadro 1) y la exudación de AO en la rizósfera (Cuadro 2) fueron afectadas por las dosis de RF y la aplicación de Al.…”

“…However, the efficiency of N fertilization is affected by factors such as soil, climate, genetic material, and cultural practices (Westerveld et al, 2003b;Oktem et al, 2010;Hawkesford et al, 2012). Consequently, the application of N should be studied under the conditions of the crop because the N nutritional status, as determined by the amount of N provided to the plants, interferes directly with the rate of absorption of the other nutrients and the dry matter accumulation of the plant (Aquino et al, 2009;Kolota and Chohura, 2015).…”

) and nitrogen doses (0, 100, 200, and 300 kg ha -1 ) on the accumulation of macronutrients by cabbage plants was studied in Jaboticabal, Brazil, from February 18 to June 2, 2004. The experimental design was a randomized complete block in a 2 × 4 factorial scheme, with three replications. Differences in the amount of macronutrients accumulated by cabbage as function of N dose and plant population, were observed. The largest amounts of macronutrients were detected at the end of the plant cycle when the plant population was the lowest. The amounts of N, P, K, and S were not significantly different when the N dose was increased from 100 to 300 kg ha -1 . The accumulated amounts of Ca and Mg were not significantly different when the N dose was increased from 200 to 300 kg ha -1 . The decreasing sequence of macronutrient extraction (Ca, N, K, Mg, P, and S) was not altered by the treatments. The period from 40 to 60 days after transplantation was responsible for half of the macronutrient accumulation by the cabbage plants.
