Abstract
A field experiment was carried out at College farm, College of Agriculture, Professor Jayashankar Telangana State Agricultural University (PJTSAU), Hyderabad, Telangana during rabi season 2022 to study the effect of drip irrigation and fertigation levels on yield attributes and yield of marigold. The results revealed that the drip irrigation scheduled at 1.2 Epan recorded significantly higher number of flowers per plant (55.3), flower diameter (5.8 cm), flower fresh weight per plant (557.2 g), flower dry weight per plant (101.9 g) and flower yield (12.11 t ha-1) than 1.0 Epan and 0.8 Epan. Whereas among the fertigation levels, 125% recommended dose of NK recorded significantly higher number of flowers per plant (53.7), flower diameter (5.6 cm), flower fresh weight per plant (538.4 g), flower dry weight per plant (92.8 g) and flower yield (11.48 t ha-1) than 100%RDF and 125%RDF.
