Effect of different levels of nitrogen and weed management practices on flower quality and yield of gaillardia (Gaillardia pulchella Foug.) under Hyderabad conditions

Abstract

The present investigation was carried out during the year 2018-2019 at Floricultural Research Station, Hyderabad to study the effect of different levels of nitrogen and weed management practices on flower quality and yield of gaillardia (Gaillardia pulchella Foug.) under Hyderabad conditions. The experiment was laid out in FRBD comprising of 20 treatment combinations with three replication. The results revealed that 180 kg N/ha (N1) and mulching with (T1) black and silver polythene sheet recorded highest flower diameter (6.77 cm), flower yield per plant (193.83 g and 196.33 g), flower yield per hectare (165.13 q and 164.39 q) compared to other nitrogen levels. However, flower diameter was highest (6.77 cm and 7.08 cm) in 180 kg N/ha (N1) and control plot (without weeding) with poor quality of flowers.
