<p>An experiment was carried out from November, 2014 to February, 2015 at Dinajpur, Bangladesh to quantify the total water requirement of Strawberry for three indigenous cultivars RU-1, RU-2 and RU-3by using 12" × 11.5" Bucket-Type Lysimeter. Water requirement in zero evaporation condition for RU-1, RU-2 and RU-3 were 86.25 ± 0.23, 49.22 ± 0.31 and 73.42 ± 0.42mm respectively, which were significantly different (p&lt; 0.01). After adding field evaporation total water requirement RU-1, RU-2 and

As plant only uses less than 1% of its total water uptake for metabolic use, Crop water requirement (CWR) can be easily represented by ET<sub>c</sub>. However our CWR value is in line with the theoretical ET<sub>c</sub> which clearly indicates level of accuracy. Therefore, it is highly recommendable for the local Commercial Strawberry growers to get robust yield.</p><p>Asian J. Med. Biol. Res. December 2016, 2(4): 672-677</p>
