Soil water potential and recoverable water stress in drought tolerant and susceptible rice varieties

Dasgupta, Pragna; Das, Bhabani S.; Sen, Soumitra K. - In: Agricultural Water Management 152 (2015) C, pp. 110-118

We conducted a two-year field experiment to determine if water stress could be exploited to recover yield in one drought resistant (Vandana) and three susceptible (IR36, IR72 and Swarna) rice varieties. Stress was induced in active tillering, flowering and grain filling stages by suspending...
