Soil Fertility Improvement / Phosphogypsyum
- The Effect of Duofos Phosphate on Growth and Yield of Phil 94-0913
- Rosario M. Bombio, George L. Talam, Solena B. Tahum, Ninfa D. Navarro and Rodrigo E. Tapay
-
- The experiment was laid out in Guimbalaon sandy clay loam soil at SRA-LGAREC, La Granja, La Carlota City from November 2004 to November 2005 to evaluate the effect of Duofos phosphate on the growth and yield of Phil 94-0913.
-
- Duofos phosphate as source of P fertilizer for Phil 94-0913 gave comparable results with the application of 18-46-0. Both fertilizer sources were significantly higher than the unfertilized control.
-
- In comparison with the recommend rate of 18-46-0, highest saving per hectare in the amount of Php 3,374.80 was obtained with the application of 3 bags Duofos phosphate. This is equivalent to about 25.38% saving in terms of fertilizer input.
-
- Available soil P analysis of the soil samples after harvest were comparable with the unfertilized plot, therefore it is recommended that Duofos phosphate will be applied every cropping, to provide the phosphorous requirement of the sugarcane plants.
- Phosphogypsum fertilization
of sugarcane (1999)
- Oscar Quilloy and
Arturo Magnaye
-
- Field experiments were laid-out on Angeles
loamy sand and Sibul clay. Phosphogypsum fertilization on Angeles
loamy sand had insignificant influence on sugarcane yields during
the plant crop. However, significant differences between yield
means were observed in the first ratoon when 3.0 T/ha of phosphogypsum
was applied once on the plant cane. Application of phosphogypsum
in Sibul clay with or without liming had insignificant effect
on sugarcane yields in both plant and ratoon crops.
