The present study was carried to standardize the dose of micro - nutrients and KNO3 for improving vegetative growth, flower yield and pigment production of Tagetes erecta cv. „Pusa Narangi‟. The seedlings were sprayed with different combinations of micro - nutrients and KNO3 treatments after one month of transplanting. The results showed that minimum time to bud initiation and anthesis was recorded under KNO3 + FeSO4 @ + . days and days, respectively. The longest flowering duration of days was recorded in KNO3 + FeSO4 @ + . The maximum plant height ( cm) was recorded in KNO3 () and maximum plant spread ( cm) was observed in ZnSO4 + MgSO4 @ . The maximum flower yield/ plant () and flower yield/m2 ( kg) was recorded under KNO3 @ . The treatment KNO3 @ produced bigger flowers ( cm) with longer stalk length of cm and higher flower weight g. The maximum chlorophyll content of was recorded in FeSO4 + ZnSO4 ( + ) and xanthophyll content in FeSO4 + Na2MoO4 @ . | Effect of micro - nutrients and KNO3 on vegetative growth, flower yield and pigments of Tagetes erecta cv. ‘Pusa Narangi’
