Some effects of nitrogen on seed production of Setaria anceps cv. Nandi

Abstract

Nitrogen applied to an established stand of cv. Nandi resulted in a large increase in seed yield and germination percentage. An application rate of 224 kg ha-1 was no more effective than 112 kg ha-1 in increasing yield but did further improve germination percentage considerably. There was no carry-over effect on the second crop of nitrogen applied early in the life of the first. Splitting the nitrogen application had no effect on the first crop.
