Nitrogen and cutting management in the production of seeds of Panicum maximum BRS Tamani

The objective of this study was to evaluate the efficiency of nitrogen, and dates of standardization cuts in yield, productivity and seed quality of Panicum maximum cv. BRS Tamani. Nitrogen fertilization, applied when inflorescence differentiation started, did not influence seed productivity and this seems to be due to the availability of N in the organic matter of the soil and by the fertilization of cover made 30 days after sowing. The average values of seed yield in the first year were up to 331.5 kg pure seeds.ha-1. The cultivar in the second year produced 86.37% less seeds than the first year, regardless of nitrogen doses and standardization cuts.
