Abstract

A major practice focusing on the production and management of pili (Canarium ovatum Engl.) was conducted at the Department of Agriculture Research Outreach Station Daet (DA-ROS Daet) in Brgy. Calasgasan, Daet, Camarines Norte from April 15, 2013 to May 27, 2013. The production area for pili at DA-ROS Daet covers a total area of 5.05 ha, which can be divided into six areas: (a) monocrop area, (b) intercropped with calamansi, (c) intercropped with coconut, (d) intercropped with corn and pineapple, (e) scion grove ? identified varieties, and (f) scion grove ? unidentified varieties. A total of 4.05 ha is planted to bearing trees ages 4-30 years old. Cleft grafting was the main propagation method for pili at DA-ROS Daet. Rootstocks were derived from germinated seedlings of unidentified varieties, while scions were obtained from unidentified varieties since the collection of outstanding pili selections (?Magayon‟, ?Mayon‟, ?Magnaye‟, ?Lanuza‟, ?Laysa‟, and ?Orolfo‟) were only about 1.5 years old. Trees in the field were rain-fed, and received no fertilizers. Weeding and removal of water sprouts were done as the need arises, while pesticide application was rarely done. Acceptable nut yield were produced with a total of 980,000 nuts for one season, yield estimate is500-2,500 nuts per tree. Mature nuts or those with partial or full purplish to black peel color, were harvested by thrashing the fruits with long pole and picking them from the ground. The harvester and the station gets 30% and 70% of the total harvested nuts, respectively. Nuts were depulped by retting, wherein nuts were soaked in tapped water for 24 h, followed by pulp removal by hand. Depulped nuts were washed in tapped water, dried under full sun for 1-2 days, and later stored in the cemented floor at the station. These primary processed nuts were picked-up by clients from Daet and other areas. For 2013, the cost of pili production at DA-ROS Daet was about PhP413,875.10, inclusive of the cost for tools and equipment, materials, farm infrastructures, labor, miscellaneous, and harvester‟s share. Gross returns from pili nuts, grafted seedlings, and germinated seedlings was PhP662,000.00. The net return was PhP248,124.90 while the return of investment (ROI) was 1.60. A proposed cropping calendar for pili at DA-ROS Daet with due consideration of the specific agro-climatic, biophysical, and socio-economic features of the research station, as well as the recommended cultural practices for pili were presented. Since pili production at DA-ROS Daet is a profitable venture despite minimal cultural interventions, adoption of the suggested calendar of activities is expected to improve nut yield (up to 5,000 nuts per tree) and production efficiency. The cropping calendar can also serve as guide for individuals or other institutions who want to venture into pili production.
