“…Lagoa Seca, EMEPA, 2007. in comparison to its application to the plant leaves (Figures 2 and 3). However, Oliveira et al (2007) obtained productivity of 12.9 t ha -1 of commercial roots of sweet potato with the utilization of cattle manure and a concentration of 20% of biofertilizer. On the other hand, Barbosa (2005) produced 13.4 t ha -1 of commercial sweet potato roots with the application of biofertilizer at the concentration of 20%.…”

“…As concentrações de 29 e 28% de biofertilizante, aplicadas no solo e via foliar, respectivamente, proporcionaram as maiores produtividades total de raízes (15,4 e 13,1 t ha -1 ) e as concentrações de 30 e 27%, também aplicadas no solo e via foliar foram responsáveis, respectivamente, pelas máximas produtividades comerciais de raízes (11 e 9,7 t ha -1 ). reasons, by the poor knowledge about the crop organic and mineral nutritional necessities (Oliveira et al, 2007). The utilization of animal organic manure is believed to improve the quality of soil and to provide economic benefits for the vegetable crop growers, since it promotes soil fertility by the nitrogen accumulation, increasing the mineralization potential of this element and, consequently, improving the nitrogen availability to the crop (Galvão et al, 1999).…”

In Northeastern Brazil, the sweet potato is cultivated in small farms, in a family farming systems, constituting themselves an alternative way for the generation of food, employment and income. This study aimed to assess the effect of cattle manure levels and biofertilizer concentrations on the sweet potato cultivar White Queen productivity. The experiment was carried out from March to September 2007 at the EMEPA Experimental Station in Lagoa Seca, Brazil. The experimental design was randomized blocks, in split split plot 6 x 4 x 2 + 1 scheme, with four replications. The plots consisted of cattle manure levels (0, 10, 20, 30, 40 and 50 t ha -1 ), the subplot of biofertilizer concentrations (0, 15, 30 and 45%) and the sub subplots consisted of methods of biofertilizer application, to the soil or leaves. Also, there was an additional control treatment using N, P and K mineral fertilizer. Commercial and total root productivity was evaluated. The levels of 30.8 and 31.2 t ha -1 of cattle manure were responsible for the highest commercial and total sweet potato root productivity (17.4 and 13.1 t ha -1 , respectively). Biofertilizer concentrations of 29 and 28%, applied to soil and to leaves provided, respectively, the greatest productivities of total roots (15.4 and 13.1 t ha -1 ), whereas concentrations of 30 and 27%, also applied to soil and leaves were responsible, respectively, for the highest commercial root productivity (11 and 9.7 t ha -1 ).

Neste trabalho objetivou-se avaliar o rendimento do inhame, cultivar Da Costa, adubado com doses de esterco bovino e biofertilizante. O delineamento experimental utilizado foi o de blocos casualizados, em parcelas subdivididas, 6 x 2 + 1 em três repetições. Nas parcelas foram testadas seis doses de esterco bovino (0; 6; 12; 18; 24 e 30 t ha-1), combinadas fatorialmente com a presença e ausência de biofertilizante e, nas subparcelas, duas formas de aplicação do biofertilizante no solo e na folha e um tratamento adicional com adubação convencional (esterco bovino e NPK). A dose de 30 t ha-1 de esterco bovino e o biofertilizante aplicado no solo e na folha produziram túberas de inhame com peso médio ideal para o comércio. O esterco bovino na dose de 19,2 t ha-1 e na ausência do biofertilizante proporcionou produtividade máxima de 20,3 t ha-1 de túberas comerciais. Nas subparcelas em que o biofertilizante foi aplicado no solo e na folha, a dose de 30 t ha-1 de esterco bovino foi responsável, respectivamente, pelas produtividades máximas de 22,8 e 24 t ha-1 de túberas comerciais. A adubação orgânica e a convencional não causaram alterações significativas no peso médio de túberas; porém, a adubação convencional aumentou a produtividade de túberas comerciais.

“…The effects of manure application have also been analyzed by other authors (Scherer et al, 2006;Oliveira et al, 2007), showing a significant increase in productivity through a quadratic effect, except at the highest doses. Machado et al (1983) also observed the effect of cattle manure with the application of 20 t ha -1 , where the yields of two harvests of irrigated rice (Oryza sativa) were similar to those of control plants.…”

Production, nutritional status and chemical properties of soils with addition of cattle manure, reactive natural phosphate and biotite schist in Massai cultivar

et al. 2010

-The objective of this work was to evaluate the effects of cattle manure, reactive natural phosphate and biotite schist on the soil fertility, yield and nutritional status of Megathyrsus spp. cv. Massai. The experiment was conducted under field conditions, in a dystrophic Red Yellow Latosol (Oxisol). It was used a randomized block experimental design with the following treatments: three natural reactive rock phosphate from Algeria (Djebel-Onk) doses (0, 100 and 200 kg ha -1 of P 2 O 5 ), three biotite schist doses (0, 150 and 300 kg ha -1 of K 2 O) and three cattle manure doses (0, 20 and 40 t ha -1 ).The application of natural phosphate increased dry matter yield, however, application of cattle manure and biotite schist did not influence this variable. Foliar levels of nitrogen, potassium and magnesium (cattle manure), phosphorous and boron (natural rock phosphate) and potassium (biotite schist) were influenced by the applied fertilizer doses. Only the levels of phosphorous in the soil and in the plant and levels of magnesium and boron in the plant show interaction with dry matter yield of Massai cultivar.
