Effect Of Varying Levels Of Rock Phosphate On The Growth And Yield Of Stylo (Stylosanthes Guyanensis Aubl.) Under Acidic Soils

Antonio I. Padaoil Jr. | Reynaldo R. Javier

Abstract:

Height of stylo plants at first and second cuttings significantly increased upon application of 300 kg/ha rock phoshate (103.71 kg P205). Fresh herbage yield also increased when 100 to 400 kg/ha of rock phosphate was applied. Total fresh herbage and dry matter yields of Stylo applied with 100 kg/ha rock phosphate and supplemented with 30 kg N/ha and 60 kg K/ha were comparable to the yield of plants applied with 00 kg P20s/ha from solophos. Plant tissue analysis from second to fourth cuttings revealed a general increase in P content, but not in N and K with increasing rates of rock phosphate application.
