dc.description.abstractThe present study entitled as, “Comparative performance of wheat genotypes under low input conditions” was conducted during winter season of 2005-06 at the Agronomy Research Area of Chaudhary Charan Singh Haryana Agricultural University, Hisar (India). The experiment consisting of three N levels, viz. 60, 90 and 120 kg ha-1 and three irrigation levels, viz. I1, (one irrigation), I2 (two irrigations) and I3 (three irrigations) in main plots and three genotypes, viz., WH-1024, PBW-343 and WH-147 in sub-plots was laid out in a split plot design with three replications. There was a progressive and significant increase in plant height, number of tillers m-1 row length, leaf area, dry matter accumulation, LAI and CGR of wheat with increase in no. of irrigation from 1 to 3 and N levels from 60 to 120 kg ha-1. Application of 120 kg N ha-1 gave higher yield and yield attributes of wheat than 60 and 90 kg N ha-1. Similarly, application of three irrigations gave significantly higher yield and yield attributes of wheat than one and two irrigations. Total nutrient uptake was positively influenced by irrigation and N levels. Total water use was lowest (285 mm) while water use efficiency was highest with one irrigation. The moisture extraction from the uppermost soil layer (0-30 cm) was higher than lower layers (30-90 cm). Water use efficiency increased markedly with the increase in N levels. Among genotypes, PBW-343 gave significantly superior performance than WH-147 and WH-1024 in terms of grain yield and net returns ha-1. Quality of wheat in terms of protein content, sedimentation value and hectoliter weight was also improved with the increase in number of irrigations and N levels.en_US
