| The small size of millet seeds is the main cause for lack of uniformity at sowing, especially because most farmers do not have appropriate seeders. Mixing seeds and phosphate fertilizers would improve seeding, resulting in a better crop stand. To study the effects of such mixture on the physiological quality of seeds, millet seeds were mixed with single superphosphate or triple superphosphate (1 kg of seeds: 2.5 kg of fertilizer), and stored in plastic bags for 0, 6, 12, 24, 48, 72, 96 and 120 hours before sowing, under laboratory conditions. After storage, seeds were separated and their moisture and electrical conductivity were determined. Seeds were then submitted to germination test under laboratory conditions. Seeds mixed with fertilizer and non-mixed... |

| The objective of this work was to evaluate the effect of fertilization with filter cakes enriched with soluble phosphate on sugarcane ratoons. The experiment was performed from November 2007 to December 2009 at Presidente Prudente, São Paulo State, Brazil, in a completely randomized block design in a 4 x 4 factorial arrangement, with the first factor consisting of doses of filter cake (0; 1; 2 and 4 mg ha-1) and the second doses consisting of phosphorus fertilizer (0, 50, 100, 200 kg ha-1 of P2O5) with 4 replicates. The following variables were evaluated: the number of tillers per meter, the leaf area index, soluble solids (ºBrix), stalk and sugar yield in the second crop cycle. We found a residual effect in the sugarcane ratoon after applying filter cakes... |
