The effects of P rate and placent on the yield of corn were studied on na Oxisol in Central Brazil. Residual effects of P applications were measured by corn growth and soil analyses. With five crops of corn grow in two and-half years about 20% of the applied P was utilized in grain and stover where grain yield appeared to be a maximum ( assuming no contribution from soil). Maximum yields of corn grain were obtained wich na initial broadscast application of 560 Kg P/há which gave a soil solution concentration of obout 0.05 ug P/ml as measured by sorption curves. The highest combination of yield and utilization occurred with an inicial broadcast application of 140 Kg P/Há and consecutive band aplications of 35 Kg P/há. The band application of P provided for rapid initial growth and also provided effective residual effects due to localized zones of high P concentration. Both double acid and .5N NaHCO3 methods of extracting soil P provided reliable estimates of critical levels, 10-15, 6-10 ug P/g, respectively, which were similar to values obtained min other areas in Brazil. Basing P requirements on field calibration of these soil test extractants should provide for 80 to 85% maximum yields using only one half the amounts of fertilizer P as that estimated by the requirement for maximum yield based on amounts of adsorbed P required to provide . 05 ug P/ml in the soil solution.

Agroindustrial residues, such as leaves of fruit plants, can be sources of bioactive molecules, thus adding value to co-products that are rarely explored in agroindustry. In this context, this study aimed to look into the phytochemical profiles in detail and to explore the antitumor potential of S. tuberosa and S. mombin leaves. We observed that, S. tuberosa leaf extract was cytotoxic in both tumor and healthy cells. S. mombin extracts selectively inhibited cell proliferation in the tumor cell line for prostate cancer (PC3) and did not significantly affect healthy cells. The metabolic profiles of the extracts were evaluated by gas chromatography coupled with mass spectrometry and twenty-three metabolites were identified. The correlation of metabolic profiles with cytotoxic tests indicated possible chemical markers that may be responsible for the inhibition of cell proliferation. This study revealed that the unexplored co-products in agroindustry may have great therapeutic potential, and therefore should be screened for biologically active compounds |
