Effect of jeevamruta on growth, flowering and yield of tuberose (Polianthes tuberosa L.) cv. Arka Prajwal

Abstract

This investigation was conducted with the aim to find out the effect of jeevamruta on growth, flowering and yield of tuberose (Polianthes tuberosa L.) cv. Arka Prajwal. The experiment was laid out in a Randomized Block Design (RBD) with three replications and seven treatments were evaluated in the present study viz., T1: 100% RDF; T2: 80% RDF; T3: 80% RDF + application of jeevamruta at 30 days interval; T4: 80% RDF + application of jeevamruta at 45 days interval; T5: 60% RDF; T6: 60% RDF + application of jeevamruta at 30 days interval; T7: 60% RDF + application of jeevamruta at 45 days interval. The results revealed that among different treatments, maximum growth and yield attributes viz., plant height (43.67 cm & 66.11 cm at the first harvest & 180 days after planting respectively), number of leaves per plant (119.80), earliness to spike emergence (89.47 days), first floret opening after spike emergence (17.13 days), number of spikes per plant (5.80), yield of florets per plant (207.67 g), per plot (2.26 kg), per hectare (20926 kg) and maximum benefit cost ratio (2.63) were recorded with T3 (80% RDF + application of jeevamruta at 30 days interval).
