Title: Growth, flowering, yield, quality and ecomomics of calendula (Calendula officinalis Linn.) as influenced by nutrients and bionoculants
Abstract: Studies were conducted on celendula (Calendula officinalis Linn.) var. Red Orange, to ascertain the influence of bioinoculants (Azotobacter @ 200 g/ha and VAM @ 15.6 g/plant) with different levels (100% 75% and 50%) of nitrogen and phosphorus on growth, flowering, yield, quality and vase life. The one month old seedlings raised in seed pans were transplanted at a spacing of 30 x 20 cm. Significantly tall statured plants (19.60 cm), higher number of branches (8.87/plant), higher number of leaves (49.30/plant), advancement of flowering (by 2 day), extension of longevity of flowers on the plant (by 2.5 day), duration of flowering (by 4 day), higher yield of flowers in terms of number (19.67/plant) and weight (72.20 g/plant and 14.46t/ha) and also resulted in significantly larger flowers (6.80 cm), longer flower stalks (7.27 cm) and vase life (5.33 day) with application of 135:90:60 kg N, P2Osand K2 O/ha + Azotobacter and VAM. Reducing the recommended dose on N and P by125% and substituting the same with Azotobacter and VAM coupled with application of recommended dose of K resulted in the highest benefit cost ration of 1.82.
