ABSTRACT
The low productivity of upland rice in Rokan Hulu is caused by the improper
planting time. Land dryness often occurs as a result of incorrectly predicting climate
which in turn hurts crop yields. This research was conducted to determine the level of
groundwater availability based on analysis of the land water balance and to determine
the planting time of upland rice. The method used in this research is survey method.
The location of soil sampling consisted of seven Homogeneous Land Units (SLH)
resulted from overlay of soil type map, administrative map, dryland agricultural map
using the GIS technique. Climate data period 1990-2019 were obtained from Balai
Wilayah Sungai Sumatera III. Land water balance analysis was performed using
Thornthwaite-Matter methods. The results of this research showed that the Rokan Hulu
regency was classified as a wet area with an annual rainfall of 2.751,1 mm (Oldemann
C1). Soil water content is classified as very sufficient criteria every month, except
June - August. Upland rice planting (inpago varieties) can be done in January, May,
and September in SLH 1 - SLH 6, while in SLH 7 upland rice planting is carried out in
January and September. Planting using local varieties can be done in February and
September in SLH 1 - SLH 6, while in SLH 7 planting can be done in March and
September. Alternating planting can also be done by planting inpago varieties in
February and local varieties in September.
