Effect of Micro - Nutrients and KNO3 on Vegetative Growth, Flower Yield and Pigments of Tagetes erecta cv. ‘Pusa Narangi’
Year: 2019
Type: article
Abstract: 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 @ 1.25% + 0.5% i.e. 52.00 days and 70.67 days, respectively. The longest flowering duration of 62.50 days was recorded in KNO3 + FeSO4 @ 1.25% + 0.5%. The maximum plant height (77.33 cm) was recorded in KNO3 (1.25%) and maximum plant spread (69.04 cm) was observed in ZnSO4 + MgSO4 @ 0.5%. The maximum flower yield/ plant (357.78g) and flower yield/m2 (2.23 kg) was recorded under KNO3 @ 1.25%. The treatment KNO3 @1.25% produced bigger flowers (6.69 cm) with longer stalk length of 6.93 cm and higher flower weight 7.27 g. The maximum chlorophyll content of 2.040mg/g was recorded in FeSO4 + ZnSO4 (0.5% + 0.5%) and xanthophyll content in FeSO4 + Na2MoO4 @ 0.5%.
