Abstract
Potassium fertilizer application for upland rice on dryland-
wet climate of South Kalimantan.
Potassium fertilizer experiments on upland rice were
conducted at Bumi Asih, Pelaihari during rainy season of
1992/1993. Two experiments have been conducted to
study: (1) The effects of KGI fertilizer and ash of husk on
upland rice; and (2) The application time and dosage of
potassium fertilizer for upland rice. The first experiment
used RGBD with three replication, and the second experiment
used factorial treatment in RGBD with four replication.
Laut tawar variety is grown at plot size of 8.5 x 6.0 m and
5.0 x 6.0 m for the first and second experiment, respectively.
All plots were treated with NP (90-90) and applied in
furrow along the rows of rice plant. The results of the
experiment indicated that:
(1) KGI fertilizer and ash of husk can increase K availability
in the soils, and affected the growth and yield of upland
rice in dryland-wet climate.
(2) The basal application of potassium fertilizer was as
good as the split application (basal and 30 day after
planting) on growth and yield upland rice.
(3) The yield of upland rice at 60 kg/ha K20 (3.31 t1ha and
3.52 t1ha) was as high as yield of upland rice at 90 kglha
and 120 kglha K20.
(4) The muriate of potash increase yield higher than that
of ash of husk.
(5) Upland rice showed linear respons to ash of husk with
dosages up to 300 kg/ha.
