|A field experiment was conducted at the University Agricultural Research Farm to assess the efficacious nature of some botanicals like Solanum xanthocarpum, Argemone mexicana and Calotropis procera and bioinoculant, Azospirillium brasilense singly and in various combinations on the growth and yield attributes of chickpea plant. Growth parameters included fresh as well as dry weights, per cent pollen fertility, number of flowers and pods, root-nodule index, nitrate reductase activity and chlorophyll content of chickpea ( Cicerarietinum L .). Agronomic parameters were calculated in terms of N, P and K in plants as well as in soil. Although all the parameters were significantly increased in these treatments, however combined application was comparatively more effective than individual application. Among the botanicals, Calotropisprocera was found better in promoting plant growth than A. mexicana and S.xanthocarpum . Root-nodulation was also found more in numbers in combined treatments. A bioinoculant like A. brasilense was also found more effective in promoting plant growth and subsequently reducing disease intensity caused by plant-parasitic nematodes. Maximum growth and productivity were observed in combined inoculation of the botanicals as well as the bioinoculatn as compared to other treatments includinguntreated one. The present study tends to enlighten the synergistic effects of botanicals and a bioinoculant in terms of releasing nutrient and antagonistic chemicals for the multiplication of the plant pathogens.|
Safiuddin Ansari has completed his M.Sc. (Botany) at the age of 23 years from CSJM University of Kanpur and MPhil in botany from Aligarh Muslim University, Aligarh. Presently he is pursuing Ph.D. in Plant Pathology from the same University on Nematodes and fungi association and their management practices on vegetable crops. He has published more than 7 research papers in Journal of high reputes. He has also attended and presented several research papers in various National and International conferences. His main thrust area is the management of plant pathogens by using organics and bio-inoculants.
