Abstract
In this study, potential and effective strains of Trichoderma such as T. harzianum (Th. Azad) and T. viride (01PP)
have been investigated and their effect of pre sowing seed treatment on germination, seedling establishment,
seedling dry weight and vigour in chickpea genotype (Radhey) was observed. The different pre sowing seed
treatments showed different responses against all seven seed quality parameters. Chickpea seeds were treated with
different concentrations of Trichoderma bioformulation such as 5%, 10%, 20% gm/kg seed followed by treatment
with 0.2% Bavistin. As a result, the percentage of seed germination was found to be higher in T. harzianum (Th.
azad) & Trichoderma viride (01PP) treated seeds with 5% bioformulation as compared to the other concentrations.
Various attributes with their observations include seed germination (92% and 90%), root length (12.38 and 12.19
cm) shoot length (4.97 and 4.32 cm) seedling length (17.38 and 16.50 cm), dry weight (1.19 and 1.88 cm), vigour
index I (5197.12 and 1485) and vigour index II (109.48 and 169.20). Among all treatments, control showed the
poorest performance for all seven seed quality attributes.

Introduction
Chickpea (Cicer arietinum L.) remarkably predominates among
other pulse crops in terms of both area and production and the crop is
widely growing in` India as well as other tropical, sub-tropical and
temperate regions of the world. Its seeds contain high amounts of
protein (25.3-28.9%), even after dehulling [1]. Chickpea seeds are
eaten fresh as green vegetables, parched, fried, roasted, and boiled; as
snack food, sweet and condiments; seeds are ground and the flour can
be used as soup, dhal, and to make bread; prepared with pepper, salt
and lemon it is served as a side dish. Among various factors attributed
to the low productivity of chickpea, such as susceptibility to wilt
diseases is the most important. Chickpea is also affected by biotic and
abiotic constraints and seed treatment is an important aspect to obtain
higher germination and good quality seedlings. Wilt (Fusarium
oxysporum f. sp. ciceri (Pad.) Snyd and Hans is one of the serious
diseases of chickpea causing heavy loss upto 10-100% depending on
fungal inoculum and environmental conditions). Chemical control of
the disease is less effective against Fusarium oxysporum f. sp. ciceri as
it survives in the soil for a longer period of time due to the presence of
chlamydospores. Therefore, cultivation of resistant varieties is an
economical approach available for the disease when only a few
resistant varieties are available [2]. As such, in the present context,
biological control of dry root rot of chickpea offers great promise. The
species of Trichoderma have attracted attention because of their
effectiveness against various plant pathogens [3]. They have shown
impressive results against many phytopathogenic fungi [4] including
M. phaseolina [5]. The isolates of Trichoderma species included in the
present study were evaluated earlier against several seed and soil borne
plant pathogens.
Materials and Methods
Freshly harvested seed of chickpea (Radhey) was obtained from
seed processing plant of C.S. Azad University of Agriculture &
Technology, Kanpur. One hundred seeds were counted and weighted
to apply the recommended dose of Trichoderma bioformulations into
three replications. The test included four treatments base materials
viz., bio-control agent (Trichoderma harzianum (Th. Azad) as well as
Trichoderma viride (01 PP) @ 5% g/kg -T1), 10%@g/kg seed-T-2),
20%@gm/kg seed- T3, Bavistin @0.2%/kg- T4) and control –T5. Four
treatments of different formulation of Trichoderm harzianum such as
5%, 10%, 20% furrow application of Trichoderma harzianum 2%
w.p.@ 2.5 kg h- and bavistin included with control. All the treatments
were tested as dry seed treatment method [6]. Different combination
of Trichoderma formulation along with 100 seeds of chickpea was
used for studies. Seed treatment was carried out with the help of paper
towel method [7]. The treated seeds were subjected to assess the
germination and vigour as per the procedure recommended by ISTA
at laboratory of Department of Seeds Science & Technology, C.S. Azad
University of Agriculture and Technology, Kanpur. Seed germination
was recorded 5 days after treating in all the experiments. Seed
germination was recorded on the basis of number of the seed
germinated out of total germination. Seedling length of the seed was
recorded 10 days after treatments in all the experiments. Shoot and
root lengths of the seeds were recorded on the basis of randomly
selected ten plants per treatment in lab experiment [8]. The dry weight
of the seedling were measured on the basis of randomly selected 10
germinated seeds per experiment were placed in hot air oven at 60º C
for 36 hours. Two recommended methods viz., germination per cent x
seedling length for vigour index I [9] and germination x dry weight for
vigour index-II was adopted during the course of investigation.
