Palomar Editor Visayas State College of Agriculture Baybay, Leyte, Philippines in collaboration with University of Georgia Athens, Georgia, U.S.A. 1998 FOREWORD Peanuts are very popular in the Philippines but not much attention has been given to this crop for research and development. It was only in the 80’s when USAID, through P-CRSP of the University of Georgia, started a holistic approach to the study of peanut with PCARRD as the coordinating unit. The P-CRSP program focused on breeding and utilization of peanuts with the Institute of Plant Breeding and the Institute of Food Science and Technology of U.P. as the lead agencies. Through this program, varieties have been developed, recommended and approved by the PSB. Furthermore, products such as peanut butter were improved and new products were developed to expand the uses of peanuts and offer variety to consumers. An enhancement project was also added to the endeavor with ViSCA as the cooperating institution. Various government and non-government agencies including agricultural colleges and universities have conducted several studies on peanut. The results of these endeavors have been thorough in some areas but sketchy in others. This publication is an attempt by P-CRSP to take a comprehensive look at the situation of peanut R & D in the Philippines today. We expect that our efforts will benefit programs designed in support of the Peanut Program in the Philippines. Lutgarda S.

Palomar, Ph.D. Professor Introduction Peanut (Arachis hypogaea L.) has been a popular crop in the Philippines, its history dating to the Spanish era. It is one of the major field legumes grown by farmers but its production has been low and erratic. Region 8, composed of the provinces of Northern Samar, Eastern Samar, Western Samar, Biliran, Leyte and Southern Leyte, represents a general picture of the peanut production situation in the Philippines (Table 1). Among the provinces in the Philippines, the top producers by volume and crop hectare in 1995 are Isabela, Pangasinan, La Union, Quirino, Cagayan, Ilocos Norte, Ilocos Sur, Aurora, Albay and Iloilo (Figure 1). However, the Cagayan Valley region produced almost half of the country’s total peanut production (Figure 2) accounting for about 50% of the total peanut production at 14,023 MT/ha, on the average (Table 2). In terms of crop area, Cagayan Valley led with 21,725 ha or 47% of the total, followed by Ilocos Region, Western Visayas, Southern Tagalog, Bicol and Western Mindanao (Table 3). 1 Table 1.
