Abstract:

The effects of irrigation level (20, 40, 60, 80 or 100 mm; cumulative pan evaporation) and spacing (15, 20 or 25 cm) on the performance of potato cv. Kufri Sutlej were studied in Hisar, Haryana, India, during rabi 1999/2000 and 2000/01. The total number of irrigations for 40, 60, 80 and 100 mm irrigation levels reached 6, 4, 3 and 2, respectively. The total number of irrigations for 20 mm irrigation level was 10 during 1999/2000 and 9 in 2000/01. In 1999/2000 and 2000/01, the greatest plant height (73.2 and 56.8 cm), yield of medium-sized (40-70 g) tubers (119.44 and 129.02 quintal/ha), yield of large (>70 g) tubers (253.17 and 154.90 quintal/ha), total tuber yield (386.89 and 304.75 quintal/ha), number of medium-sized tubers (258.00 and 242.54 per plot) and number of large tubers (130.20 and 87.09 per plot) were obtained with an irrigation level of 20 mm. Foliage weight at harvest was greatest with irrigation at 20 (149.14 and 132.31 quintal/ha) and 40 mm (139.28 and 124.30). A spacing of 15 cm resulted in the highest foliage weight at harvest (131.42 and 121.46 quintal/ha), yield of medium-sized tubers (120.94 and 119.57 quintal/ha), total tuber yield (282.49 and 243.50 quintal/ha), and number of medium-sized tubers (240.73 and 222.06 per plot). The yield (153.32 and 104.94 quintal/ha) and number (101.46 and 84.32 per plot) of large tubers were highest with a spacing of 20 cm. Water use efficiency was greatest (59.03 and 50.50 kg of tubers per mm of water used) with irrigation at 40 mm. [1 quintal=100 kg].
