Respuestas de la caña (Saccharum officinarum L.) variedad POJ 2878, a dosis y fuentes de fósforo en suelos de ladera en Antioquia
ICA's soil program established four trials in Sugarcane, variety POJ 28-78 in Cocorná, Barbosa and Arnagá (counties located in Antioquia). The red soils of these places were slope, strongly acids, low to high in organic matter (1,6 to 17,69o) and low in P-available (1,5 to 3,2 ppm-Bray II), Ca,...

| Summary: | ICA's soil program established four trials in Sugarcane, variety POJ 28-78 in Cocorná, Barbosa and Arnagá (counties located in Antioquia). The red soils of these places were slope, strongly acids, low to high in organic matter (1,6 to 17,69o) and low in P-available (1,5 to 3,2 ppm-Bray II), Ca, Mg and K-exchangeable. The main object of these trials was to study the effect of different sources of phosphorus: Superphosphate (SF1), Thomas Slags (ET) and Rock Phosphate (RF) and two dosages (75 and 150 kg/Ha of P205) in yields of sugarcane (TCA), sugar (TAH) and saccharose concentration. The results showed good yields (TCH and TAH) and saccharose concentration with 75 - 150 kg/Ha of P205 of SF1 and ET or 150 kg/Ha of P205 with RF at planting time and first cut. |
