Comparative evaluation of different controlled Irrigation methods as applied to Rice production. [Unpublished Undergraduate Thesis Don Mariano Marcos Memorial State University - North La Union Campus, Sapilang, Bacnotan, La Union]. Lakasa ti Sirib, DMMMSU Institutional Repository.https://lakasa.dmmmsu.edu.ph/handle/123456789/1529This study was carried out to determine the best irrigation method for rice production using the different controlled irrigation systems namely: drip irrigation, furrow irrigation, and flooding irrigation in terms of growth, yield and water application efficiency as well as to perform the cost and return analysis. The study was conducted at the Don Mariano Marcos Memorial State University, Baroro Farm, Bacnotan La Union from October 2009 to January 2010. Rice variety 152 (tubigan) was being used in the study and was raised for 101 days for each treatment. Results revealed that the height of the plant were not significant, the flooding irrigation method has the highest applied water thus produces highest yield. With drip irrigation method having the highest cost of expenses gives the second highest yield, while furrow irrigation method gives the lowest yield.en-US
