Abstract
A screening experiment using nine cultures of VA-mycorrhizal fungi was carried out on cashew var. VTH-12. Glomus macrocarpum, G. versiforme and a local isolate C- II (Coconut black) inoculated plants recorded higher shoot and root weight as compared to those inoculated with other VA-mycorrhizal cultures. All the VA - mycorrhizal inoculation treatments resulted in greater plant growth as compared to uninoculated control. The phosphorus content was also more in VA-mycorrhizal inoculated plants. Cashew is generally grown in poor soils which are not auitable for the cultivation of other crops. The plant requires considerable amounts of nutrients for the growth and production. Considerable work have been reported on the association VA-mycorrhizal (VAM) which increases the uptake of P, Zn and Cu and plant growth in annual crops, but not much information is available for The perennial crops except in citrus (Kleinshnidt and Gerdemann, 1972; Krishna et si, 1983; Thapar and Khan, 1986). In the present study, nine VAM cultures were screened for their influence on cashew seedlings.
