Abstract:
The objective of this study was to find the effect of controlled release fertilizers (CRF), jeevamrit and PGPR on Dendranthema grandiflora Tzvelev. The experiments were laid out in 6-inch clay pots with 12 treatments replicated thrice consisting of two genotypes i.e. ‘UHFS Chr-56’ and ‘UHFS Chr-68’. CRF A (7.5 g/pot), CRF B (11.2 g/pot) and jeevamrit @ 5% (250 ml/pot at monthly interval) along with PGPR (KS₅ + KS₆) were used. Out of the two genotypes, plant height, spread, and flower diameter was more in the genotype ‘UHFS Chr-68’ where as ‘UHFS Chr-56’ had greater number of flowers and pot present ability score. Application of CRF B (11.2 g/pot) along with jeevamrit @ 5% (250 ml/pot at monthly interval) were effective in increasing the plant height, plant spread, number of flowers per plant and pot present ability score. However, CRF B (11.2 g/pot) + PGPR (KS₅ + KS₆ as root dip method) were effective in increasing the flower diameter.
