A decreasing trend in the production of cassava can be observed
in Table 4. from 1994 to 1995. The yield per hectare is 8.31
mt per hectare and decreased to 4.57 mt/ha in the year 2003.
The province of Albay reflected the highest decrease from 12.61
mt/ha in 1994 and 1995 to 0.77 mt/ha in 2003. The reason could
be that rootcrops are mostly grown in non-favorable areas where
soil condition is poor and water supply is less. Areas favorable
to agricultural cultivation are converted into other high value
crops (Table 4).
Based on 2003 data, the provinces
of Camarines Sur and Catanduanes registered the highest yield
per hectare of 5.13 and 5.28 mt/ha, respectively. This is followed
by Camarines Norte with 4.92 mt/ha.
