AGROCLIMATIC / CROP CONDITION ASSESSMENT FOR APRIL 2023
OVERVIEW
Most of the provinces in Luzon received inadequate amount of water required to support the expected production of both rice and corn crops. Specifically, the following crops at their respective prevailing stages: rice crops at flowering stage over Ilocos Region, Cagayan Valley, Central Luzon, Cordillera Autonomous Region, and provinces of Sarangani and South Cotabato; rice crops at nursery stage in Basilan and Sulu Province; corn crops at prevailing establishment stage over Ilocos Region, Cagayan Valley, Cordillera Administrative Region except for Kalinga province, Central Luzon Region except for Aurora province, and CALABARZON Region except for Quezon province; corn crops at prevailing silking stage in the provinces of Camiguin, Misamis Occidental, Agusan del Norte, Agusan del Sur, and Dinagat Islands.
Sufficient amount of rainfall that could support the standing rice and corn crops was observed mainly in some provinces of Mindanao. Specifically, the following crops at their respective stages: rice crops at prevailing nursery stage in provinces of Lanao del Sur and Maguindanao; rice crops at prevailing flowering stage in provinces of Cotabato, Cotabato City, and Sultan Kudarat; corn crops at prevailing establishment stage in Eastern Visayas region and in the provinces of Kalinga, Aurora, Quezon; corn crops at prevailing vegetative stage in province of Compostela Valley, Davao del Norte, and Davao del Sur; corn crops at prevailing silking stage in the provinces of Bukidnon, Lanao del Norte, Misamis Oriental, Surigao del Norte, Surigao del Sur.
The observed rainfall for the month of April were caused by the influence of the following atmospheric systems: easterlies, low-pressure area, ridge of high-pressure area (HPA), trough of LPA, and Intertropical Convergence Zone (ITCZ). The occurrence of Tropical Depression Amang (TD Amang) from 10-12 April 2023 induced rainfall over the provinces in the National Capital Region, Central Luzon, CALABARZON, MIMAROPA, Bicol, and Eastern Visayas regions. One-day (Rx1day) and multi-day (Rx5day) indices of heavy rainfall were highest over Bicol, Eastern Visayas, and SOCCSKSARGEN regions, which may have been beneficial for the pre-planting activities or preliminary land preparation for rice paddy.
