Abstract

Sesbania rostrata and Aeschynomene afraspera were cultivated in a sandy infertile soil (Khorat series) under upland conditions to clarify effects of single or combined application of ammonium sulfate (AS), triple superphosphate (TSP) and phosphate rock on their growth. TSP was effective in enhancing growth of the 2 plants. PR was considered to have both enhancing effect (supply of P) and adverse effects (excess or deficiency of some nutrients). The enhancing effect was prodominating over the adverse effects for S. rostrata and the reverse was true for A. afraspera. As appeared to have 2 contrasting effects also : supply of N and a harmful effect. The harmful effect became evident when AS was applied in combination with PR and was suspected to be NH subscript 3-toxicity.
