Abstract

Maize (Zea mays L.) is an important crop of the world and ranks third after rice and wheat. Plant stand was maximum (97.33%) with treatment of Tricoderma harzianum + FYM and FYM + Neem cake + T. harzianum + T. viride. Green manuring gylricidia and sunhemp did not perform better but enhanced the biocontrol activities. Presowing application of FYM neemcake and T. harzianum was most effective in avoiding the infection and a reduses the stalk rot at later stage. The treatment increased yield levels by reducing the lodging at 105 days to the extent of 10.19%. Significant effects of irrigation levels was recorded at 105th day with stress at tasseling and silking resulted in more disease i.e. 39.51%. Treatment (FYM + Neem cake + T. harzinum + T. viride) recorded highest grains (Le. 1363.14 kg/ha) followed by T. harzinum + FYM with 1253.89 kg/ha.
