“…Moreira et al (2002) worked with different doses of P and found the highest concentration in the third, fourth, and fifth cutting of alfalfa. The contents of Cu, Fe, Mn, and Zn in our study were similar to those found by Moreira et al (2000).…”

“…The concentration did not reach the levels achieved by Moreira et al (2000), but was close to the maximum values described by Raij et al (1997). Lloveras et al (2004) conducted a similar study in Spain and did not observe statistically significant differences between treatments; however, they found values lower than in our study.…”

“…Moreira et al (2000) also found a higher level of B of the first cut of alfalfa and higher levels of Cu and Mn in the fifth section in an experiment to test the Ca: Mg ratio. However, unlike in our study, (Table 1) they found higher amounts of Zn in the sixth cutting.…”

The objective of this study was to evaluate the response of alfalfa (Medicago sativa L.) in the nutritional composition to the application of biofertilizers. The experiment was conducted with increasing doses of biofertilizers in a greenhouse at the Faculty of Veterinary Medicine / UNESP, Araçatuba -Sao Paulo, Brazil, from April to October 2010. The experimental design was completely randomized with six biofertilizer doses from cattle manure (0, 25, 50, 100, 200, and 400 m 3 ha -1 ) and five replications. Cuts were performed, on average, every 27 days, 10 cm above the ground when 10% of the plants were flowering. Biofertilization had a positive significant impact on foliar nitrogen, potassium, calcium, magnesium, sulfur, and shoot iron concentrations. The values of crude protein, acid detergent fiber, and neutral detergent fiber did not differ between doses of biofertilizers. Biofertilization is a viable alternative for nutrition of this species, showing positive results in the nutritional composition of alfalfa. However, but long-term studies are necessary to assess the environmental impact of these fertilizers.

“…The concentration of B decreased with increasing doses of biofertiliser (Figure 4) and most likely occurred with increased extraction yield of the DM with higher doses of biofertiliser. These data are consistent with Moreira et al (2000), who tested various Ca:Mg ratios, and Werner et al (1997), who required only a pound of boron per ha. biofertiliser (Figure 4) and most likely occurred with increased extraction yield of the DM with of biofertiliser.…”

The objective of this study was to evaluate the use of biofertilisers for the production of alfalfa shoot, root and nodule dry matter, and also, to evaluate the chemical properties of the soil. This study was conducted in the greenhouse of the Support Department, Animal Production and Health, Faculty of Veterinary Medicine/UNESP, Araçatuba -SP, from May to October 2010. The experimental design was completely randomised with six biofertiliser doses (0, 25, 50, 100, 200 and 400 m 3 ha -1) and five replicates. The biofertiliser doses were the primary treatments and the cuts (five) were subplots. The cuts were performed, on average, every 27 days at 10 cm above the soil. At the end of the experiment, the roots, nodules and soil from all experimental units were collected for chemical analysis. We observed a linear increase in dry matter production of the shoots relative to the doses studied. The dry matter production of the roots and nodules was not significantly different. The chemical properties of the soil significantly improved for calcium and magnesium as well as the sum of bases and base saturation with biofertiliser application. Biofertilisers can be used for agricultural production and favourably alter the soil characteristics.

O experimento foi realizado em casa de vegetação do Departamento de Apoio, Produção e Saúde Animal da Faculdade de Medicina Veterinária/UNESP, Campus de Araçatuba -SP, de maio a outubro de 2010. O delineamento experimental foi inteiramente ao acaso, sendo seis doses de biofertilizante (0, 25, 50, 100, 200 e 400 m 3 ha -1 ) e cinco repetições. As doses de biofertilizante foram consideradas como tratamentos principais e os cortes (cinco) como subparcelas. Os cortes foram realizados, em média, a cada 27 dias, a 10 cm de altura do solo. Ao final do experimento foram coletadas as raízes, nódulos e o solo de todas as unidades experimentais para análise química. Foi observado aumento linear na produção de matéria seca da parte aérea em relação as doses estudadas. A produção de matéria seca de raiz e nódulos não apresentaram diferença significativa. Para os atributos químicos do solo ocorreu resposta positiva para os teores de cálcio, magnésio, soma de bases e saturação de bases com a aplicação do biofertilizante. O biofertilizante pode ser utilizado como insumo na agropecuária para melhorar a produção e alterar favoravelmente os atributos do solo.

Sugarcane Response to Boron and Zinc in Southeastern Brazil

et al. 2011

View full text Add to dashboard Cite

The application of micronutrients on the sugarcane crop in Brazil is not a widespread practice, due to the few studies developed under Brazilian conditions. Nevertheless, the crop advance to lower fertility soils and the introduction of varieties with greater yield potential will change the nutrient management. In this context, two experiments were developed with boron (B) or zinc (Zn) application with the aim of evaluating yield, technological attributes and biometric indexes of sugarcane during the plant cane cycle and the residual effect of this fertilization on the first ratoon. The experiments were developed in Pirassununga, São Paulo, Brazil. In both trials, the doses of B (2 and 4 kg ha -1 ) and Zn (3 and 6 kg ha -1 ) were applied in top dressing. The crop was harvested around 13 months after the treatments application and, after the first harvest, all the plots received the same doses of N, P 2 O 5 and K 2 O, to evaluating the residual effect on the first ratoon. The B application reduced the above ground biomass, TSS (tons of sugarcane stalks per hectare) and sugar yield in the plant cane. However, the Zn fertilization improved the stalk technological quality, as well as providing a residual effect, increasing the above ground biomass, TSS and stalk yield (dry matter). The dry matter accumulation showed three growth phases during the plant cane cycle, similar to the B and Zn accumulation. The fertilization with B, especially with high solubility sources, must be careful to avoid yield reduction.
