| Abstract | A study was done in rice field of AIT in the dry season 1987 to find out the effect of various moisture stress intensity and duration on growth and development of wetland rice. Stomatal resistance increased with stress . Panicle differentiation and flowering time was not affected by stress. Moisture stress reduced the Leaf Area Index. The degree of reduction depends mainly on the stage of the crop, duration and frequency of stress during growth period. The effect was greater when stress was at early stages. Dry matter production was lower when the stress occured at early stages. Dry matter of higher stressed plants was generally lower than lower stressed plants after relief especially when stress occured before reproductive stage. Lack of surface water reduced the dry matter. As the stress increased before flowering shoot fraction to l eaf decreased. Long stress during reproductive phase and short stress during ripening phase gave higher yield . |
