Author(s): HJ Kapadiya and AM Moradiya
Abstract: A field experiment with nine treatment combinations of chemical and bio control agent were carried out at Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh. Result revealed that the collar rot (2.64%) and stem rot (1.27 %) incidence was minimum in tebuconazole 1.5 g/kg seed treatment and two spray of same fungicide at 15 days interval. Late leaf spot (23.82 %) and rust (21.57%) severity were minimum in seed treatment with T. viride @ 10g/kg seed, furrow application of T. viride at the time of sowing @ 4 kg enriched in 50 kg FYM/ha, Broadcasting T. viride @ 4 kg enriched in 50 kg FYM/ha at 40 DAS, accompanied by 2 spray of tebuconazole @ 1ml/lit at 15 days intervals. Whereas maximum pod (2230 kg/ha) and haulm (5256 kg/ha) yield was showed in tebuconazole 1.5g/kg seed, furrow application of T. viride at time of sowing @ 4 kg enriched in 50 kg FYM/ha same was enriched and applied at 40 DAS and two spray of tebuconazole @ 1ml/lit at fortnightly intervals.
The comparative efficacy of tebuconazole alone and its combination with biological control agent revealed lower collar rot and stem rot diseases in all plots heaving seed treatment of tebuconazole. Similarly, lower tikka and rust were recorded in plots heaving foliar application of tebuconazole. The higher pod and haulm yield were recorded in treatment with tebuconazole and combinations with biocontrol agent treatments.
