io-fertilizers are living microorganisms, derived from roots or soil, which improve the soil microbial content, growth and yield
attributes in rainy season tomato. In an experiment, 14 treatments comprising of various combinations of bio-fertilizers, organic
manures and chemical fertilizers were compared to assess the impact of different sources of nutrients on performance of tomato.
The results revealed that plant height after 30, 60 and 90 days of transplanting, number of branches per plant, number of fruits per
plant and leaf surface area was found to be maximum with the application of
Azotobacter
along with recommended dose of fertilizers
(T
1
). Likewise, application of
Azospirilum
along with recommended dose of fertilizers (T
3
) produced maximum fruit weight, fruit
diameter and total yield. Highest soil organic carbon content (0.38 %) was observed in the treatments T
11
(FYM @ 20 t/ha along
with
Azotobacter
and
Vesicular-Arbuscular Mycorrhizae
(VAM)) and T
12
(Farm Yard Manure (FYM) @ 20 t/ha). Highest bacterial
count (26.2×10
6
) and actinomycetes count (36×10
4
) was recorded in treatment T
12
(FYM @ 20 t/ha). It can be concluded that, the
application of
Azotobacter
along with recommended dose of inorganic fertilizers improve vegetative growth, while
Azospirillium
along with recommended dose of inorganic fertilizers improves yield attributes in rainy season tomato as far as the sustainability and
environmental considerations are concerned. The present study highlights the need of usage of bio-fertilizers along with organic and
inorganic manures/fertilizers to enhance the nutrient availability and improve soil health.
