The experiment was carried out to study the effect of different combinations of NPK and biofertilizers on zinnia (Zinnia elegans J.) at SKUAST – K, Shalimar, Srinagar, Jammu and Kashmir. The experiment was laid out in Randomised Block Design with three replications. The experiment consist of three levels of chemical fertilizers (NPK @ 28:16:10, 21:12:7.5, and 14:8:5 g/m2) along with different combinations of biofertilizers [Azotobacter, PSB (Phosphorous Solubilizing Bacteria), KSB (Potassium Solubilizing Bacteria), Azotobacter + PSB, Azotobacter + PSB + KSB]. The results revealed that treatment combination of (NPK 21:12:7.5 g/m2 + Azotobacter + PSB + KSB) recorded maximum plant height (125.32 cm), number of primary branches (9.73), plant spread (66.55 cm2), minimum days taken to anthesis (48.88 days), maximum flowering duration (42.42 days), seed yield per plant (21.19 g) respectively compared to control.
