Abstract
The present investigation entitled “Effect of Bio-vita on Tomato
Production” was carried out at Vegetable Research Farm CCS H.A.U., Hisar
during 2004-05 to study the effect of fertilizers, Bio-vita granules and Bio-vita
liquid spray levels on tomato CV. Hisar Arun (Sel-7). Data were recorded on
flowering, fruit yield and quality characteristics.
Earliest flowering and more number of flowers per cluster and fruits
per truss were recorded in 75% of RDF+ application of Bio-vita granules @
20kg/ha + one Bio-vita liquid sprays at early bloom stage of tomato plants.
Fruit set was early under treatment 50% of RDF+ without Bio-vita granules +
1 Bio-vita liquid spray at first fruit set stage of tomato plants.
Highest fruit set percentage (75.4%) was recorded under the treatment
75% of RDF+ without Bio-vita granules + two Bio-vita liquid sprays (one at
pre-bloom and one at early bloom stages of tomato plants). The number of
fruits per plant was maximum (36.2) in treatment 75% of RDF + application
of Bio-vita granules @ 20kg/ha + three Bio-vita liquid sprays (one at
pre-bloom, one at early bloom and one at first fruit set stages). Maximum
number and weight of A-grade fruit was observed in treatment 100% RDF+
Bio-vita granules @ 20kg/ha + three Bio-vita liquid sprays (one at pre-bloom,
one at early bloom and one at first fruit set stages), while number of B-grade
fruit was obtained in 50% RDF+ Bio-vita granules @ 20kg/ha + one Bio-vita liquid spray at first fruit set stage. The maximum number and weight of
C-grade fruit was recorded in 100 % RDF + Bio-vita granules @ 20kg/ha +
two Bio-vita liquid sprays (one at pre-bloom and one at first fruit set stages).
Average fruit weight was significantly influenced by Bio-vita granules
and Bio-vita liquid spray levels. It was observed highest (53.5g) in treatment
100% RDF+ Bio-vita granules @ 20kg/ha + two Bio-vita liquid sprays (one at
pre-bloom and one at early bloom stages). The application of Bio-vita granules
and Bio-vita liquid spray significantly increased the fruit yield. Maximum
fruit yield per plant (1.8 kg), per plot (108.6 kg) and per ha (434.4q) was
recorded in treatment 75% RDF+ Bio-vita granules @ 20kg + three Bio-vita
liquid sprays (one at pre-bloom, one at early bloom and one at first fruit set
stages).
Total soluble solids and acidity of fruits were not affected significantly
by application of different treatments. Ascorbic acid was slightly influenced
by application of Bio-vita, seaweed extract. It was found maximum (26.7) in
treatment of 50% RDF+ no granules + three Bio-vita liquid sprays (one at
pre-bloom, one at early bloom and one at first fruit set stages).
The gross returns ranged from Rs.83520 to Rs.173760/ha. The benefit
to cost ratio also varied from 0.54 to 2.15. The highest net returns of
Rs.118487 was realized from the treatment 75% of RDF + application of
Bio-vita granules @ 20kg/ha + three Bio-vita liquid sprays (one at pre-bloom,
one at early bloom and one at first fruit set stages). It was followed closely by
Rs.116053 from the treatment 50% of RDF+ without Bio-vita granules + 3
Bio-vita liquid sprays (one at pre-bloom, one at early bloom, and one at first
fruit set stages). Similarly, there were five other important treatments for
higher returns.
It was concluded that for increasing tomato production the use of both
formulations of Bio-vita as a source of nutrients, for stimulating the
utilization of other plant nutrients to fullest extent, and saving on the cost of
chemical fertilizers by reducing their requirement for the crop will prove a
very helping venture for the farmers. The study needs further confirmation of
these results at farmer fields on commercial lines.
