Not AvailableOn- farm demonstrations on Trichoderma harzianum were undertaken to empower
farmers and show the potential against root rot complex and wilt disease in major
pulse crops. Accordingly, a project was implemented during 2008-2011 in six
villages with 620 farmers under rainfed conditions of Sumerpur Block, Hamirpur
district in Bundelkhand of Uttar Pradesh. The identified native strain of
Trichoderma harzianum (IPT 31) was multiplied and supplied to farmers for seed
treatment in chickpea, lentil and pigeonpea crops. The results showed that the
overall reduction in plant mortality due to root rot complex over control was 32.1%
and 14.3% in chickpea and lentil, respectively. However, the reduction in wilt
incidence was observed 26.7% in chickpea and 25.9% of lentil. Further, the
percent increase in yield over the control was 16.6% and 12.6% in chickpea and
lentil, respectively. The additional yield in chickpea and lentil from T. harzianum
application was received 1.30 q/ha and 0.93 q/ha with economic gain of
2600
and
2800/ha. The impact of T. harzianum in pigeonpea was observed to a lesser
extent. The availability of soil moisture played an important role in effectiveness of
Trichoderma. The increase in awareness and knowledge on nature, role and
benefits of T. harzianum; methods of application, source of availability and market
price was observed between 20 to 70 percent.Not Availabl
