RDE Abstract of Completed Research
Soil Fertility Improvement / Lahar
- Fertility Improvement of lahar
for sugarcane cultivation; first ratoon (1998)
- Oscar Quilloy and
E. Estanislao
-
- Sugarcane production of ratoons in lahar
was improved by green manuring, mudpress and bagasse compost
application along with 180-180-180 kg/ha NPK fertilization. Triple-14
was significantly better than urea fertilization on lahar. The
productivity of lahar can be improved by continuous amelioration
with organic materials such as green manure crops, farm and sugar
mill wastes.
- Fertility improvement of lahar
for sugarcane cultivation (1997)
- Oscar Quilloy and
E. Estanislao
-
- Incorporation of different soil ameliorants
and inoculation with Myco-VAM and/or Bio-N on lahar-filled CHB
tanks did not significantly affected yield parameters of sugarcane.
Although statistically comparable, more millable stalks and higher
sugarcane yields in comparison with the control were obtained
by lime, mudpress and bagasse compost treatments. The different
soil ameliorants tested on 6 to 8 feet deep lahar field gave
significant results. Sugarcane yields on triple 14 fertilized
plots in combination with bagasse compost and mudpress were higher
than with Urea or Triple-14 fertilization alone and other organic
amendments. Continued application of indigenous sources of fertilizers
is highly recommended to improve fertility of thick lahar deposits
and sustain profitable yield levels.

- Disease incidence and soil-borne
organisms under "lahar" condition (1997)
- Angestal Vitug
-
- Five sugarcane diseases were observed on
sugarcane under lahar condition nine months after planting during
the onset of rainy season. These were smut, mosaic, red rot of
the midrib, ring spot and banded sclerotial disease. Three fungal
species were isolated in lahar soils, namely: Trichoderma sp.,
Fusarium sp. and Aspergillus flavus.
