Abstract

Cowpea is an important crop of Indian subcontinent and its losses by the reniform nematode (Rotylenchulus reniformis) cause’s significant harm to the farmers. To find out a herbal management practice a pot experiment was carried out under protected condition consisting of completely randomized design with six seed treatments using plant leaves extract viz., Tulsi (Ocimum tenuiflorum), Pyrethrum (Chrysanthemum cinerarieaefolium), Datura (Datura stramonium), Ashwagandha (Withania sominifera), Congress grass (Parthenium hysterophorus) @ 10 per cent concentration, and untreated control laid out in four replications.The soil was inoculated with 2J/g soil with reniform nematode. Datura (10%) was found best treatment followed by Pyrethrum (10%) and Congress grass (10%) in improving plant growth of cowpea and reducing reproduction of reniform nematode. According to the findings, Datura (Datura stramonium) significantly increased cowpea plant growth characteristics viz., shoot length by 42.8%and no. of nodules/plant by 51.50%. Datura application also, reduced number of female count at the time of harvest by 51.76% and final nematode population (200cc¬-1 soil) by 56.36% as compared to the control pots. It can thus be inferred that the use of Datura leaves extract can be a potential treatment in the management of reniform nematode, Rotylenchulus reniformis.

Conclusion

Results of seed treatment trial with plant leaves extract of Datura (Datura stramonium) @ 10 per cent concentration were highly promising, followed by Pyrethrum (Chrysanthemum cinerarieaefolium) @ 10 per cent concentration, and Congress grass (Parthenium hysterophorus) @ 10 per cent concentration for improvement in the plant growth of cowpea and reducing infection and reproduction of reniform nematode. It can be concluded that the application of Datura leaves in the management of this nematode is highly effective, the application rate and availability of Datura in semi-arid areas of Rajasthan makes this an economic as well as employable management practice.
