Abstract

The investigation on “Effect of fertigation and hydrogel on growth and flower yield of tuberose (Polianthes tuberosa L.) cv Mexican single” was carried out at Herbal Garden, college of Agriculture, UAS, Raichur during the year 2021-22. The experiment was comprised with four main treatments and three sub treatments laid out in split plot design with three replications. The results revealed that the treatment F1 at H1 (Fertigation with 100% RDF and Hydrogel as bulb dip @ 0.2%) recorded significantly higher plant height (68.82 cm), number of leaves per clump (225.92) and number of tillers per clump (24.51). The same treatment also recorded significantly higher flower yield (10.29 t/ha) was 29.49% increase over control (5.84 t/ha) which was due to increase in yield attributes viz, number of spikes per clump (21.76), flowers per spike (58.63), length of flower (6.21 cm), diameter of flower (4.75 cm), weight of 100 flowers (66.74 g) and flower yield per clump (161.99 g) confirmed as best treatment which could be recommended to the farmers for better income. Challenges during the study was proper supply of NPK through fertigation to all plants. It will be overcome with practice of proper maintenance of drippers supply of fresh form of fertilizers.

Conclusion

Among the different treatments, the treatment F1H1 (100% RDF through fertigation with 0.2% hydrogel as bulb dip) recorded higher yield (10.29 t/ha) which was due to improvement in vegetative and yield parameters. The same treatment was also found better for getting higher flower yield with quality and net returns with higher B:C ratio.
