ABSTRACT
Field experiments were conducted with potato in a silt-loam soil of the Bangladesh Institute of Nuclear Agriculture sub-station farm, Rangpur, Bangladesh during the winter season (November-March) of 1993-94 and 1994-95 to study its yield response due to deficit irrigation imposed at different growth stages. Nine different irrigation treatments were followed with the combinations of four different growth stages (i.e. stolonization, tuberization, bulking and tuber enlargement) allowing water stress at single to all stages. Irrigation showed significant effect on the yield of potato in 1993-94. But there was no significant yield difference due to different levels of watering and stresses of potato during 1994-95. Highest potato yields of 21.0 t/ha and 25.97 t/ha were obtained in 1993-94 and 1994-1995 by applying a total of 7.38 cm and 7.06 cm irrigation water, respectively, at stolonization, tuberization and bulking stages. It was also found that water stress at the early two stages (I. e. stolonization and tuberization) showed sharp negative response to the yield of potato compared with bulking and tuber enlargement stages. Thus, the experimental results revealed that irrigation at tuber enlargement stage could be withheld without significant yield decrease in potato.
