Abstract:
The investigation was carried out during 2021 and 2022 for evaluation of the effect of inorganic fertilizers along with bio fertilizers on vegetative and yield characters of tomato. At 30 DAT, maximum plant height was recorded under the treatment T₈ (Azotobacter 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus) followed by treatment T₁₂ (Azospirillum 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus). At 60 DAT, maximum plant height (110.85 cm) was recorded under the treatment T₈ (Azotobacter 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus). At 90 DAT, again maximum plant height (159.42 cm) was recorded under treatment T₈ (Azotobacter 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus) followed by treatment T₁₂ (153.86 cm). At 120 DAT, maximum plant height was recorded under the treatment T₈ (Azotobacter 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus) recording a plant height of 180.84 cm. This was followed by treatment T₁₂ (Azospirillum 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus) recording a plant height of 175.28 cm. During the next year of experiment (2022), at 30 DAT, maximum plant height of 89.27 cm was recorded in treatment T₈ (Azotobacter 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus) followed by treatment T₁₂ (Azospirillum 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus). At 60 DAT, maximum plant height of 112.02 cm was recorded under the treatment T₈ (Azotobacter 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus) followed by treatment T₁₂ (Azospirillum 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus). At 90 DAT, again maximum plant height of 162 cm was recorded under the treatment T₈ (Azotobacter 1 kg/ha + 120 kg Nitrogen + 60 kg Phosphorus) followed by treatment T₁₂ (156.44 cm). At 120 DAT, similar trend was observed and maximum plant height (182.02 cm) was recorded in treatment T₈ followed by treatment T₁₂ (176.46 cm) whereas minimum plant height was recorded in control (129.54 cm).
