Effect of Azotobacter and nitrogen on growth and yield of Tomatocrop (Lycopersicumesculantum) cv. “Pusa Rubby”

The present investigation was carried out at the Horticultural Research farm, Department of Horticulture, Ch. Charan Singh University, Meerut to assess the effect of different treatments of azotobacter culture with different levels of nitrogen on growth and yield parameters. Twenty three days old seedlings were transplanted in experimental field. There were nine treatment combinations consisting two methods of Azotobacter chroococcum application (soil treatment with 2 kg per hectare and Seedling root dip treatment @ 2 kg per 10 liters of water) two levels of nitrogen application 75 kg per hectare and 150 kg per hectare and one control. Result revealed that seedling treatment with Azotobacter performed superior to soil treatment for all growth and yield parameters. The different levels of nitrogen exhibited pronounced effect of improving the various yield contributing traits were recorded maximum at 150 kg. nitrogen in each case. The parameters were recorded maximum under the treatment combination Seedling treatment with Azotobacter culture @ 2 kg+10 liters of water and 150 kg nitrogen/ha. Followed by Soil treatment with Azotobacter @ 2kg / ha. and 150 kg Nitrogen / ha.), Seedling treatment with Azotobacter @ 2 kg +10 liters of water and 75 kg Nitrogen / ha. and Soil treatment with Azotobacter @ 2 kg / ha. and 75 kg Nitrogen/ha.
