Abstract:
A field experiment was carried out in the Agri-farm of Horticulture of Lovely Professional University, Kapurthala district, Punjab, India during the year 2021-2022 on “Effect of organic and inorganic fertilizer on growth and development of Calendula officinalis L.” to elucidate the effectiveness of integrated nutrient management on crop calendula. The experiment was laid out in randomized block design with 10 treatments and 3 replications and the treatments included T1 [control], T2 [NPK dose (45:90:75 kg/ha)], T3 [75% NPK+ Azotobacter 3kg/ha+ PSB 3kg/ha], T4 [75% NPK+ Azotobacter 3kg/ha+ PSB 3kg/ha+ FYM 5ton/ha], T5 [75% NPK+ Azotobacter 3kg/ha+ PSB 3kg/ha+ FYM 5ton/ha+ Vermicompost 2.5ton/ha, T6 [75% NPK+ Azotobacter 3kg/ha+ PSB 3kg/ha+ FYM 5ton/ha+ Vermicompost 2.5ton/ha+ Neem cake 2.5ton/ha], T7 [ 50% NPK+ Azotobacter 5kg/ha+ PSB 5kg/ha], T8 [50% NPK+ Azotobacter 5kg/ha+ PSB 5kg/ha+ FYM 5ton/ha], T9 [50% NPK + Azotobacter 5kg/ha+ PSB 5kg/ha+ FYM 5ton/ha+ Vermicompost 2.5ton/ha], T10 [50% NPK+ Azotobacter 5kg/ha+ PSB 5kg/ha+ FYM 5ton/ha+ Vermicompost 2.5ton/ha+ Neem cake 25q/ha]. The result of the study revealed that there was significant difference between the treatments. The treatment T6 [75% NPK+ Azotobacter 3kg/ha+ PSB 3kg/ha+ FYM 5ton/ha+ Vermicompost 2.5ton/ha+ Neem cake 25quintal/ha] seems to shows significant increase in all the parameters that being plant height, number of branches per plant, stem diameter, number of leaves per plant, leaf area, plant spread, flower weight, number of flowers per plant, flower diameter and vase life.
