| dc.description.abstract | This study was conducted to detect, determine the distribution incidence and severity on anthracnose-twister through mapping using remote sensing technology in onion growing areas of Laur, General Mamerto Natividad and Palayan City, Nueva Ecija. A total of 17 barangays were surveyed in which time (9) from the Municipality of Laur, (three (3) from General Mamerto natividad and 5 barangays from the City of Palayan. Total areas affected were 142.84 ha out of 548.19 has surveyed in which 23.99 ha were damaged in Laur until harvested. In the Municipality of General Mamerto Natividad, the total areas affected were 138.16 ha out of 495.29 ha and had a 1.75 ha damaged, while in Palayan City a total of 8.18 ha were damaged out of its total area of 91.24 ha. Results from Spectroscopy shows that reflectance variation in healthy and infected leaves whereby the higher the reflectance the more the onion damaged was. Estimated yield for Laur was 9,369.95 MT, 10,499.3 MT in General mamerto Natividad and 775.55 MT in Palayan City. | |
