Abstract
AbstractA pot experiment was conducted during 2013–14 to observe the potential role of some organics and bio-organics such as Calotropis procera, Glomus fasciculatum, and Azotobacter chroococcum on some growth attributes of chickpea and subsequently on the root-knot development caused by Meloidogyne incognita. Individual and conjoint treatments significantly enhanced the plant growth parameters as compared to unamended control. Physiological parameter such as chlorophyll content also exhibited significant improvement in all the treatments over non-amended control. The highest improvement in growth parameters of chickpea was observed in combined application of G. fasciculatum and A. chroococcum in pots amended with C. procera. Moreover, combined treatments of both bio-inoculants and C. procera markedly reduced the multiplication and reproduction rate of root-knot nematodes in terms of number of root galls and nematode population. Percent mycorrhization in terms of external and internal colonizations was in...
Highlights
Chickpea (Cicer arietinum) is one of the most important pulse crops in India, occupying about 6.67 × 106 ha and producing 5.3 × 106 t annually (Singh, 2012)
The effects of individual as well as concomitant treatments were recorded in relation to different growth parameters of chickpea like plant length, fresh as well as dry weights, number of pods and branches per plant, percent pollen fertility, and chlorophyll content (Figure 1, Tables 1 and 2)
Plant treated with C. procera, G. fasciculatum, and A. chroococcum alone and in combination significantly increased plant dry weight over uninoculated control (Figure 2)
Summary
Chickpea (Cicer arietinum) is one of the most important pulse crops in India, occupying about 6.67 × 106 ha and producing 5.3 × 106 t annually (Singh, 2012). Organic farming has been an important sector of sustainable agriculture. Aisha Sumbul and her group are working on organic agriculture. They are indulged to create the awareness among the large-scale farmers about the organic farming. Chickpea is an important pulse crop being grown all over the world. It is highly economically important crop because of its high protein content, and due to its ability to fix atmospheric nitrogen. The organic matter and bio-fertilizers, used as an alternative to inorganic fertilizers, can be proved to be beneficial for both crop production as well as for environment
