Abstract:
A field experiment with application of liquid jeevamrutha in marigold cv. Calcutta Orange at different dosages and frequent intervals was carried out at Horticultural Research and Extension Centre, Kanabargi (Belagavi Dist.) (Under University of Horticultural Sciences, Bagalkot) during rabi season of 2019-20 and 2020-21. The objective is to study the performance of marigold under different dosages and frequency of application of jeevamrutha. In pooled data, application of liquid jeevamrutha @ 1000 litre per hectare with an interval of 15 days (D₃F₁) recorded significantly maximum growth and yield parameters like plant height (37.90 cm), plant spread (E-W and N-S direction) (23.80 and 24.47 cm), number of primary branches (9.22) and stem diameter (1.11 cm) at harvest stage. Flowering or yield parameters are days to first flowering (34.50), days to 50% flowering (45.07), flower diameter (3.42 cm), individual flower weight (3.92 g), number of flowers per plant (64.67), shelf life (4.40 days), flower yield (9.59 t/ha), fresh biomass (14.13 t/ha) and dry biomass (3.87 t/ha) was compared to other interaction treatments. In control (recommended package of practice) recorded significantly maximum plant height (39.40 cm), plant spread (E-W and N-S direction) (26.73 and 27.40 cm), number of primary branches (9.18) stem diameter (1.23) and leaf area per plant (179.63 cm²) at harvest stage and maximum flower diameter (3.46 cm), individual flower weight (4.07 g), number of flowers per plant (69.83), flower yield (10.71 t/ha), fresh biomass (15.43 t/ha) and dry biomass (4.30 t/ha) were compared with other treatments.
