| Summary, etc | Two field experiments were conducted for eight consecutive years (1987-1995) at two locations in Assam to assess the influence of potassiuma and magnesium and their interaction on growth, yield and nutrient contents of rubber (Hevea brasiliensis). Girth and girth increment did not show significant improvement due to application of K and Mg but it significantly increased their contents in leaf and had synergistic effect on leaf N and P contents. Application of K significantly increased the availability of K. Also increased the availability of P and organic carbon content and reduced the availability of Ca and Mg. Similarly application of Mg improved the Mg availability as well as organic carbon and available P and Ca. Antagonism between K and Mg was expressed in soil as well as in leaf. Addition of K reduced the Mg availability in soil and Mg concentration in leaf. Conversely addition of Mg reduced the soil available K and leaf K concentration. |
