Forecasted Rainfall and Temperature: Basis for one-year Planting Calendar for Upland Rice (Oryza Sativa L.) in Bayombong, Nueva Vizcaya

Abstract

The study aimed to determine a planting calendar for upland rice (Oryza Sativa L.) in Bayombong and its nearby municipalities based on temperature and rainfall data of the said localities together with the temperature and water requirements of the upland rice. Ten years of data on Temperature and Rainfall in Bayombong were used to forecast 12 months of data on temperature and rainfall using three forecasting methods of the SPSS, NCSS, and MS Excel. Upland rice crop can be grown successfully where the average temperature is 21 0C or more for the 5 to 6 months; it has 10 stages starting from the germination stage to the ripening stage; the temperature and water requirements in its stages must be maintained within what the plant required to sustain plant growth and development. The forecasted data on temperature and rainfall were then matched to the temperature and water requirements of the upland rice starting from germination to ripening which will be ready for harvesting. The study was able to determine the best timing for the plant the upland rice; it is on the third week of April up to the last week of August. Upland rice planted at this time interval has a high forecasted percentage of survival as the temperature and water requirements of the plant in its stages were all sustained.
