Establishment of dwarf long-bean on sand tailings

Vimala P., . and Lim A.H., . (2008) Establishment of dwarf long-bean on sand tailings. [Proceedings Paper]

A field experiment was conducted to determine the yield response of dwarf long-bean grown on sand-tailings 95 sand to organic and inorganic fertilizers. Treatments comprised of poultry manure 15 moisture at 0 15 30 45 and 60 t/ha and inorganic fertilizer N: P2 05 : K20: MgO 12 : 12: 17 : 2 trace at 0 0.75 and 1.5 t/ha. Results obtained showed that increasing rates of both poultry manure and inorganic fertilizer increased yields significantly. Without inorganic fertilizer yields ranged from 4 - 13 t/ha only when poultry manure was increased from 0 to 60 t/ha. At the second level of inorganic fertilizer 0.75 t/ha yields ranged from 9 - 26 t/ha when poultry manure increased from 0 to 60 t/ha. At the highest level of inorganic fertilizer 1.5 t/ha yields ranged from 9 - 28 t/ha when poultry manure was increased from 0 to 60 t/ha. The yield response to poultry manure at 1.5 t/ha inorganic fertilizer can be represented by the equation Y -0065x2 0.6712x 10.5. The optimum rate of poultry manure is 51 t/ha. The expected yield at this rate is 28 t/ha. It is concluded that about 45 - 50 t/ha of poultry manure and about 1.5 t/ha of inorganic fertilizer can be recommended for the conventional cultivation of dwarf long-bean on sand-tailings with expected yields of about 28 t/ha. For organic cultivation at least 50 t/ha of poultry manure is required but the yield obtained would be half the yield under conventional cultivation.

Abstract

A field experiment was conducted to determine the yield response of dwarf long-bean grown on sand-tailings 95 sand to organic and inorganic fertilizers. Treatments comprised of poultry manure 15 moisture at 0 15 30 45 and 60 t/ha and inorganic fertilizer N: P2 05 : K20: MgO 12 : 12: 17 : 2 trace at 0 0.75 and 1.5 t/ha. Results obtained showed that increasing rates of both poultry manure and inorganic fertilizer increased yields significantly. Without inorganic fertilizer yields ranged from 4 - 13 t/ha only when poultry manure was increased from 0 to 60 t/ha. At the second level of inorganic fertilizer 0.75 t/ha yields ranged from 9 - 26 t/ha when poultry manure increased from 0 to 60 t/ha. At the highest level of inorganic fertilizer 1.5 t/ha yields ranged from 9 - 28 t/ha when poultry manure was increased from 0 to 60 t/ha. The yield response to poultry manure at 1.5 t/ha inorganic fertilizer can be represented by the equation Y -0065x2 0.6712x 10.5. The optimum rate of poultry manure is 51 t/ha. The expected yield at this rate is 28 t/ha. It is concluded that about 45 - 50 t/ha of poultry manure and about 1.5 t/ha of inorganic fertilizer can be recommended for the conventional cultivation of dwarf long-bean on sand-tailings with expected yields of about 28 t/ha. For organic cultivation at least 50 t/ha of poultry manure is required but the yield obtained would be half the yield under conventional cultivation.
