Abstract

The field experiment was carried out during the year of 2016-17 and 2017-18 in sodic black soils having ESP 35±2 with wheat crop (cultivar HI- 1077) to know the comparative performance of two irrigation systems, border strip irrigation (BSI) and sprinkler irrigation (SI) with respect to wheat yield and water productivity (WP). The BSI was adopted with 8 liters per second (LPS) stream size at 65, 75 and 85 per cent cut off distance (COD) in the plot size of 6 m × 50 m. The SI was also adopted by giving 2, 3 and 5 cm irrigation water with plot size of 24 m × 50 m. Irrigation was scheduled on the basis of IW/CPE ratio as 1.2. Results revealed that higher grain yield of 2869 nd 2567 kg ha-1 was obtained in SI with irrigation depth 3 cm during 2016-17 and 2017-18 respectively, while the lowest yield of 1941 and 1673 kg ha-1 was noticed under BSI with COD 65 per cent. The highest values of water productivity (WP) as 0.71 and 0.64 kg/m3 with the mean value of 0.68 kg m-3 were noticed in case of SI with depth of irrigation 3 cm during 2016-17 and 2017-18, respectively, followed by BSI with cut off distance of 85 per cent and stream size 8 LPS as 0.44 and 0.38 kg m-3 during 2016-17 and 2017-18, respectively with mean as 0.41 kg per m3. The minimum water use (40.13 cm) was recorded under SI with irrigation depth 3 cm followed by 41.06 cm with irrigation depth 2 cm. However, the maximum water use (52.87 cm) was recorded in case of BSI with COD 65 per cent followed by 50.28 cm in BSI with COD 85 per cent. Results implied that sprinkler irrigation with irrigation depth 3 cm scheduled on the basis of 1.2 IW/CPE ratio was most suitable irrigation compared to border strip irrigation as it gave additional yield of 650 kg ha-1 (31.43%) over the best border strip irrigation. This additional yield and enhanced water productivity justified investment on sprinkler irrigation. In case of three sprinkler irrigation treatments, average uniformity coefficient was 85.9%. It indicated that distribution of irrigation water by sprinkler was uniform and acceptable.
