Infrared thermometery and xylem water potential as an index for the assessment of water stress and scheduling of irrigation in rice



Infrared thermometery and xylem water potential as an index for the assessment of water stress and scheduling of irrigation in rice



Indian Journal of Agricultural Research 32(1): 11-16



Irrigation experiment for two years on wet land rice (Oryza sativa L.) under deep water table conditions showed that intermittent submergence two days after disappearance of ponded water from the soil surface produced grain yields similar to continuous submergence. This shows that plant water deficit in I2 (7.5 cm submergence, two days after drying) were critical and soil induced PSIL and Tc-Ta in I2 could be considered as an index for scheduling of irrigation in rice for optimum yield. The values of PSISMW and (Tc-Ta) SMW in I2 during the growth period fluctuated between 0 and 1.0 bar and 0 to 0.5degreeC respectively. Thus, rice crop should be irrigated when PSISMW <1.0 bar and (Tc-Ta) SMW >0.5degreeC in a sandy loam soil under deep water table condition without significant reduction in grain yield from the continuous submergence.
