Groundnut is the principal vegetable oil crop in India and about 85 per cent groundnut area under remains rain fed. Stem rot of groundnut is more prevalent in the area and is capable of causing considerable loss in the yield when left unmanaged.
In order to find out an effective method of managing the disease, an integrated approach was adopted by combining the use of bio agents, organic amendments and fungicides alone and in combinations.
Seed treatment with tebuconazole @ 1 g kg−1 and with commercial formulation of Trichoderma harzianum @ 5g kg−1 seed along with soil application of neem cake @ 1.3 t ha−1 maintained its superiority over other treatments by recording the least PDI, maximum germination percentage (98.20%), root length (14.62 cm), shoot length (35.54 cm), number of pods per plant (32.57) and pod yield (3920.0 kg ha1) which may be synergistic effect of organic amendment with bioagent. However, all the sole treatments also managed the disease to some extent but greater control was recorded in combination treatments than alone.
