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.
