| Abstract | The study was carried out at the Asian Institute of Technology from January to June, 1985 with a view to observing the effect of microclimate on crop development in wetland rice. Three plots were transplanted at 28 days interval with a photo-insensitive, short day, improved rice variety, RD 23. February to May was found to be the best season for irrigated rice among the three plots' period of the experiment, Upto their maximum values, both biomass and Leaf Area Index were found to increase linearly with accumulated temperature These were also found to increase following a power function of DAT upto their maximum values. Micro lysimeter as designed by Tomar and O'Toole was found non-suitable for ET measurement in the rainy season and also for continuous long duration study. Daily maximum temperature higher than 35ํ C was found to hamper crop growth in vegetative stage. The average daily evapotranspiration at maximum seasonal requirement was found to be close to open pan evaporation. Photosynthetic Efficiency at it's most among the three plots were estimated to be 4.68 % at the booting period in the 1st week of April. |
