Abstract
Background: The growth and development of crop needs optimum ratio of micronutrient in soil. Deficiency or efficiency of these nutrients in soil is affecting the plant growth leads to severe loss in the productivity and yield. For proper growth and yield, it is necessary to maintain soil fertility. Different treatments of ZnSO4 had promotive effects on almost all of the growth, yield and qualitative parameters discussed. Objective: Study effect of Zn together with bioagent (Trichoderma sp.) that have better response in terms of growth and yield compared to Zn alone. Material and methods: A pot experiment of greengram (Vigna radiata (L.) was conducted with five different treatments viz. ( T3- Soil treatment with zinc, T7- Soil treatment with zinc and antagonist, T11- Soil treatment with zinc and pathogen, T15- Soil treatment with zinc, pathogens and Trichoderma sp, Control: not treated) to test the response of greengram (V. radiata (L.) plants grown in alluvial soil under warehouse condition. Zinc was applied to the soil in the form of zinc sulphate (ZnSO4.7H2O) in concentrations (50 mg/ kg-1) in which the green gram plants were grown. Results: The plant samples were analysed 45 days after sowing. In green gram (V. radiata L.) plants antagonist with zinc (50 mg kg-1) were also found to be most efficient in increasing all the parameters of growth as Total plant length, Leaf, Internodes distance, Fresh weight, Dry weight and Index vigour compared to control. Maximum increases in plant height and seed weight was most significantly. Conclusions: The result of the present study revealed that Trichoderma sp had performed best in all the in vitro and in vivo studies. Trichoderma sp can be applied to control soilborne diseases mainly wilt complex disease of greengram (V. radiata (L.) significantly with an ecofriendly approach. In addition there significant increase was recorded in yield parameters of greengram (V. radiata (L.). Trichoderma sp along with zinc can be applied as integrated disease management strategies in greengram (V. radiata (L.) for better results but the desired results can also be easily achieved with application of Trichoderma without involving any chemical.
Keywords: Zinc, Vigna radiata, Trichoderma Sp.
