AGROCLIMATIC / CROP CONDITION ASSESSMENT FOR DECEMBER 2022
OVERVIEW
Adequate rainfall received for the month of December was favorable for both the rice and corn crops, especially, those at the following prevailing stages: rice crops at the Nursery stage over Quezon, Cavite, Batangas, the southern part of Occidental Mindoro, Marinduque, and most parts of Masbate; rice crops at Vegetative stage in most of the Western Visayas (except Antique), Negros Oriental, and Eastern portion of Davao region (i.e., Davao Oriental, Davao del Sur, and Davao del Norte); rice crops at Reproductive stage in the Province of Maguindanao; corn crops at the Silking stage in Quirino, Isabela, Cagayan, Batanes, Kalinga, Apayao, Bulacan, Aurora, Laguna, Cavite, the southern portion of Batangas, Southern part of Occidental Mindoro, and Marinduque; corn crops at the Establishment stage in Guimaras and Antique; corn crops at the Vegetative stage in most parts of SOCCSKSARGEN (except in Cotabato) and Maguindanao. However, some areas in the country received insufficient rainfall which may have caused a negative impact on crop production of rice and corn crops at the following prevailing crop stages: rice and corn crops at any stage in Ilocos Region, Nueva Viscaya, Mountain Province, Ifugao, Benguet, Abra, Zambales, Tarlac, and Nueva Ecija; rice crops at Nursery stage in Oriental Mindoro; rice crops at Vegetative stage in Antique; and corn crops at the Silking stage in Bataan and Oriental Mindoro.
Meanwhile, excessive rainfall received may indicate potential damage to the standing crops, particularly the rice and corn crops at the following prevailing stages: rice crops at the Nursery stage in Rizal, Laguna, Romblon, Palawan, Bicol Region (except Masbate), and Northern Mindanao; rice crops at Vegetative stage in Siquijor, Cebu, Bohol, Davao Oriental, and Compostela Valley; rice crops at Reproductive stage in Eastern Visayas, Caraga region, and BARMM (except Maguindanao); rice crops in the Flowering stage in Zamboanga Sibugay, Zamboanga del Norte and Isabela City; corn crops at Silking stage in Rizal, Quezon, Romblon, Palawan, and Bicol Region; corn crops at Establishment stage in Negros Occidental, Iloilo, Capiz, Aklan, and Central Visayas; and corn crops at the Vegetative stage in Zamboanga Peninsula, Cotabato, Tawi-tawi, Sulu, Lanao del Sur, and Basilan.
Furthermore, notable amount of monthly rainfall received could have caused adverse impacts on both rice and corn crops mostly in the Caraga region and Palawan. This heavy rainfall amount was mainly attributed to the effects of the LPAs, Shear Line, and Tropical Storm Rosal (December 10-12, 2022). The NDVI indicates generally healthy vegetation throughout the country except for some areas in Nueva Vizcaya, Cagayan, and Isabela. In addition, both one-month and three months SPEI shows generally near normal conditions throughout the country, except in some areas that experienced slightly below average rainfall (i.e., SPEI1-Eastern part of Mindoro, SPEI3-portions of Nueva Ecija, Tarlac, Benguet, and Ifugao) and slightly wetter than normal rainfall conditions (i.e., SPEI1-Basilan and Isabela City, SPEI3-eastern part of Maguindanao, Basilan, and Sultan Kudarat).
Meanwhile, excessive rainfall received may indicate potential damage to the standing crops, particularly the rice and corn crops at the following prevailing stages: rice crops at the Nursery stage in Rizal, Laguna, Romblon, Palawan, Bicol Region (except Masbate), and Northern Mindanao; rice crops at Vegetative stage in Siquijor, Cebu, Bohol, Davao Oriental, and Compostela Valley; rice crops at Reproductive stage in Eastern Visayas, Caraga region, and BARMM (except Maguindanao); rice crops in the Flowering stage in Zamboanga Sibugay, Zamboanga del Norte and Isabela City; corn crops at Silking stage in Rizal, Quezon, Romblon, Palawan, and Bicol Region; corn crops at Establishment stage in Negros Occidental, Iloilo, Capiz, Aklan, and Central Visayas; and corn crops at the Vegetative stage in Zamboanga Peninsula, Cotabato, Tawi-tawi, Sulu, Lanao del Sur, and Basilan.
