Description |
The present investigation was conducted during 2005 at vegetable research farm of CCS HAU Hisar to study the effect of Azotobacter and nitrogen on tomato production. There are four nitrogen levels (0, 50, 75,100 kg/ha) and five Azotobacter strains (0, Ala-27, Mac-21, Mac-27, Mac-68). Experiment was layout in Spilt Plot Design allocating nitrogen levels to main plots. Transplanting was done on 31 Jan 2005. Application of 100 kg N/ha significantly improved plant height, number of fruits per plant and total fruit yield but it delayed flowering in comparison to other nitrogen levels. Maximum fruit yield per plant and 12 per hectare was recorded with 100 kg N/ha. However, it was statistically at par with 75 kg N/ha and significantly superior to other doses of nitrogen. Similar results were observed in case of seed quality (weight of seed per kg fruits, test weight, germination %). Inoculation of Azotobacter strains improved the growth and yield attributes significantly over control. Maximum fruit yield per plant and total fruit yield (q/ha) was recorded with strain Mac-27 which was closely followed by Mac-68 and these were significantly superior to control. Interaction effect of nitrogen and Azotobacter strains was significant on growth, fruit yield and seed weight per kg fruits. Highest fruit yield per plant and total fruit yield (q/ha) was under the combination of 100 kg N/ha and Azotobacter strain Mac-27. However, it was at par with all the treatment combinations of 100 kg N/ha and remaining Azotobacter strains and 75 kg N/ha plus Mac-27 and significantly superior to other treatment combinations. |
