Abstract: A field experiment entitled “Comparative performance of late sown wheat varieties under saline water irrigation” was conducted during Rabi 2017-18 at Soil Science Research area of CCS Haryana Agricultural University, Hisar. The experiment was three types of water main plot treatment S0, canal water (0.3-0.4 dSm-1), S1, Saline water irrigation (5- 6 dSm-1), S2, Saline water irrigation (9-10 dSm-1) comprised performance of four varieties V1: KRL 210, V2: WH 1124, V3: DBW 90 and V4: HD 3059 cultivation in the different of saline water. As sub plot treatments. Experiment was laid out in split plot design with four replications. Saline water irrigation S2 (EC between 9-10 dSm-1), significantly reduced the plant height, dry matter accumulation, leaf area index, leaf area duration, crop growth rate, net assimilation rate and relative growth rate at 30, 60, 90 and 120 days after sowing, respectively. Significantly higher plant height, leaf area index and leaf area duration was observed in variety WH-1124 at 30, 60, 90 and 120 days after sowing as compared to other varieties. All varieties performed same in terms of CGR and NAR at 90 days after sowing except HD-3059. Effective tillers, grain/spike and test weight were significantly reduced i.e. 54.2, 34.9 and 34.2 g, respectively, at saline water irrigation S2 (EC between 9-10 dsm-1) but at S1 (EC 5-6 dsm-1) resulted in to same yield attributes as obtained under canal water irrigation. Variety WH-1124 resulted into higher number of effective tillers (58.3) and grains/ spike (36.3). Grain yield (3249 kg/ha), straw yield (5423kg/ha), biological yield (8672 kg/ha) and harvest index (37.44%) were significantly reduced by saline water irrigation S2 (EC between 9-10 dSm-1) as compared to S0 levels (3875 kg/ha, 5943 kg/ha, 9818 kg/ha and 39.46%, respectively). Variety WH-1124 was found better in terms of grain yield, straw yield, biological yield and harvest index i.e. 3707 kg/ha, 5835 kg/ha, 9532 kg/ha and 38.78% as compared to all other varieties. The nitrogen content and uptake in grain and straw and protein content in grain were significantly reduced under S2 level but S1 level resulted into almost similar results as obtained under S0 level (canal water irrigation). Variety WH-1124 resulted into higher N content, N-uptake and protein content in grain over all other varieties. While DBW-90 resulted into higher N content, N uptake and protein content in straw over other verities. Available nitrogen and phosphorous in soil was significantly reduced under saline water irrigation (EC between 9-10 dsm-1) as compared in canal irrigation water. The available potassium was significantly higher under S2 level of irrigation. All the varieties did not influence the available N and P status of soil. Soil EC and organic carbon per cent at 0-15 cm soil depth was significantly increased and decreased, respectively under S2 saline water irrigation (EC between 9-10 dsm-1). None of the varieties affected the soil properties significantly. Overall the use of saline water having EC between 5-6 dSm-1 can result into comparable yields along with variety WH- 1124 without affecting phenology, growth, yield attributes, quality and soil properties in wheat.
