Abstract
A field trial was conducted during 2010 and 2011 to study the comparative performance of drip irrigation and conventional furrow irrigations on yield and physiological performance of strawberry. The experiment was laid out in randomized block design with five irrigation treatments, viz., (T1) drip irrigation at 120 % ETc (crop evapotranspiration), (T2) drip irrigation at 100 % ETc, (T3) drip irrigation at 80 % ETc, (T4) drip irrigation at 60 % ETc and (T5) furrow irrigation with ‘V’ volume of water, and each treatment was replicated five times. The results revealed that drip irrigation at 120 % gave significantly higher fruit yield compared with drip irrigation at 80 and 60 % ETc and furrow irrigation. Similarly, the photosynthetic rate, transpiration rate, number of stomata and size of stomata were higher in drip irrigation at 120 % ETc, followed by drip irrigation at 100 % ETc. Although the physiological performance was slightly better under 120 % ETc in comparison to 100 % ETc drip irrigation, but there was 16–30 % increase in yield in case of 100 % ETc irrigation treatment over furrow irrigations treatment. Besides drip irrigation at 100 % ETc also provided better physiological performance over furrow irrigation.
