Viability of Para grass (Brach-iaria mutica) seed and the effect of fertilizer nitrogen on seed yield

Abstract

The application of nitrogenous fertilizer significantly increased both the number of reproductive tillers and the yield of harvestable seed of para grass. There was no response to phosphate nor an~ N x P interaction. At the completion of general anthesis, mean seed yields of 11·86, 22 · 37 and 27 · 53 lb/ac were realized for nil, 50 and 100 lb nitrogen per acre treatments respectively.
