Abstract
The experiment was carried out at Regional Horticultural Research Station (RHRS), ASPEE College of Horticulture, Navsari Agricultural University, Navsari during the year 2017-18 to 2019-20. The experiment was laid out in Randomized Block Design having nine Treatments (T1: 200:200:250 NPK g/plant (RDF) + 10 kg FYM/plant, T2: 80% RDN + soil application of Azotobacter 20 ml per plant at the time of planting, 3 and 6 months after the first application, T3: 60% RDN + soil application of Azotobacter 20 ml per plant at the time of planting, 3 and 6 months after the first application, T4: 80% RDP + soil application of PSB 20 ml per plant at the time of planting, 3 and 6 months after the first application, T5: 60% RDP + soil application of PSB 20 ml per plant at the time of planting, 3 and 6 months after the first application, T6: 80% RDK + soil application of KMB 20 ml per plant at the time of planting, 3 and 6 months after the first application, T7: 60% RDK + soil application of KMB 20 ml per plant at the time of planting, 3 and 6 months after the first application, T8: 80% RDF + soil application of Azotobacter + PSB + KMB each 20 ml per plant at the time of planting, 3 and 6 months after the first application and T9: 60% RDF + soil application of Azotobacter + PSB + KMB each 20 ml per plant at the time of planting, 3 and 6 months after the first application) which repeated thrice. The results of three years pooled revealed that among the different treatments maximum plant height (133.74 cm) at 3 and 9 month was obtained with in T9 treatment (60% RDF + soil application of Azotobacter + PSB + KMB each 20 ml per plant at the time of planting, 3 and 6 months after the first application. While, maximum plant height (155.79) at 6 month was recorded in T8 which was at par with T9, T2 and T1. Treatment T9 recorded significantly highest stem girth (18.80, 28.33 and 38.81 cm) and number of leaves (18.31, 23.04 and 29.01) at 3, 6 and 9 month after planting, respectively. In case of soil nutrient analysis and microbial count, available N (293.49 kg ha-1), available P (70.18 kg ha-1), available K (441.60 kg ha-1), PSB count (122.44 x 105) and KMB count (238.11 x 105) were also recorded maximum in the treatment T9 (60% RDF + soil application of Azotobacter + PSB + KMB each 20 ml per plant at the time of planting, 3 and 6 months after the first application). Flowering characters and Azotobacter count were found non-significant.
