Abstract
Experimental studies on chickpea carried out at Seed Research and Technology Center, Rajendranagar,Hyderabad during rabi, 2010-12 revealed that seed treatment with Pseudomonas fluorescens at 10 g/kg seed along with soil application of P. fluorescens at 3 kg/acre was found to be the best and effective as it recorded least incidence of wilt disease (11.26 per cent) and root rot (1.43 per cent) followed by seed treatment with Tebuconazole (100% Raxil T at 25 g/l = Tebuconazole 4 g/l + Triflunuron) at 1 ml/kg seed with less incidence of wilt (13.62 per cent) and root rot (0.44 per cent) under field conditions. Seed treated with Benomyl at 2 ml/kg seed produced maximum yield (7.17 q/ha) but remained at par with the treatment, P. fluorescens at 10 g/kg seed along with soil application of P.fluorescens at 3 kg/acre (7.02q/ha) and Tebuconazole at 1 ml/ kg seed (6.62 q/ha). Maximum germination percentage was recorded with Benomyl (Benomyl 500 WP) at 2 ml/kg seed (treated check) and Tebuconazole at 1 ml/ kg seed (95 per cent) followed by treatment with P. fluorescens at 10 g/kg seed along with soil application of P.fluorescens at 3 kg/acre (94 per cent). Maximization of growth parameters like root length, shoot length and total seedling length were observed with Benomyl at 2 ml/ kg seed as 17.0 cm, 10.3 cm and 27.3 cm, respectively. Considering seedling vigour index as an important seed quality character, P.fluorescens and Benomyl at 2 ml/kg seed recorded high seedling vigor index. The per cent recovery of infested seeds from the harvest was found to be low with treated seeds compared to the control.
