Peanut has been a popular crop in the Philippines. It is considered one of the major field legumes grown by farmers but its production has been low and erratic. Among the provinces in the Philippines, the top producers of peanut are Isabela, Pangasinan, La Union, Quirino, Cagayan, Ilocos Norte, Ilocos Sur, Aurora, Albay and Iloilo. However, the Cagayan Valley region produced almost half of the country’s total peanut production.
In the Philippines, peanut can be grown throughout the year provided inputs, especially the water requirement are adequately available. In general, dry season crop (October-January) gives higher yields and beans of better quality than the rainy season crop.
Peanuts will mature within four months after planting. It is ready for harvest when the leaves wilt and turn yellow if planted in summer. This is also known if the shell of the peanut is hard. Pull up about ten plants, open and see the shell of the grain. If there are dark streaks or roots inside the shell, the peanut is ready for harvest. If the peanut is not mature, the shell is shriveled. If it is over matured, this roots in the soil, or starts to germinate.
Pull up the plants with the help of a spade or fork, or plow the two sides of the rows before pulling them up. Stack up the harvest in a dry place and air the peanuts.
Newly harvested peanuts contain 50-55% water. If this will be dried in the sun, dry them until the humidity is about 12%. If it will be stored in a closed container, dry until 6-8% humidity.
Carefully remove the kernels from the shell do not allow them to be broken or their seed cover by bruised. This will be the start of rotting.
It is better to store peanuts with their shell to avoid pest destruction. If watermelon is planted together with the peanuts, this will be harvested earlier by one month. But it will go on bearing fruit after the first harvest. The body of the watermelon plant will remain in the field until the peanuts are harvested.
