Yield Per Hectare

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.
