Thesis (Ph.D.)--University of California, Riverside, 1988.

Includes bibliographical references

The geography of the Irrawaddy Delta (Burma) and the neccessity to grow more rice, soybeans and maize are briefly discussed. Empirical methods for estimating potential evapotranspiration for the Irrawaddy Delta during the dry season are evaluated to determine water use for soybeans, maize and rice. According to the statistical methods applied, the Penman method as modified by Frere and Popov appears most suitable.

520 $a The geography of the Irrawaddy Delta (Burma) and the neccessity to grow more rice, soybeans and maize are briefly discussed. Empirical methods for estimating potential evapotranspiration for the Irrawaddy Delta during the dry season are evaluated to determine water use for soybeans, maize and rice. According to the statistical methods applied, the Penman method as modified by Frere and Popov appears most suitable.
520 $a Two methodologies, the Equivalent Hours of Maximum Net Photosynthesis (EHMNP) and the growing degree days (GDD) are used to evaluate the possibility of the growing of rice, maize and soybeans on the delta during the dry season. The EHMNP unit is the net photosynthetic response of a plant for one hour at optimum condition of temperature and light where hours with partial responses can add together to make full hours. EHMNP totals regressed against yields of rice, soybeans and maize grown in the United States result in a positive linear relationship. Application of EHMNP totals to the Irrawaddy Delta in the dry season suggest relatively low yields of rice, soybeans and maize.
520 $a The GDD used here is obtained by the summation of mean temperature above a threshold temperatures for the corresponding crops. Regression analysis of GDD versus crop yields suggest that within the domain of the data used, rice yields decrease as GDD increase. There is a curvilinear relationship between GDD and yields of soybeans and maize, where yields increase as GDD increase to a certain degree beyond which yields decline. The GDD indicated lower than optimum yields of soybeans, maize and rice during the dry season.
