Comparison of effect of split application of nitrogen at different stages on growth and flower yield of gaillardia on red and black soils

Experiments were conducted separately on red and black soils to know the effect of split application of nitrogen on growth and flower yield gaillardia during 1995-96 at UAS, Dharwad. Application of nitrogen @ 150 kg/ha of two splits, i.e., 50% as basal dose and 50% at initiation of flowering recorded the highest flower yield (39.04 and 33.16 t/ha) on red and black soils, respectively. The increase in flower yield was mainly due to improved yield attributes like number of flowers per plant, flower size and yield per planting.
