SUMMARY

A field experiment was conducted at Regional Research Station, Bawal (CCS HAU, Hisar) in Rabi, 2019-20 on barley crop grown in split plot design with three main plot and six sub plot treatments and replicated thrice owing to a total of fifty four plots. The experiment was carried out on dual purpose six rowed barley variety BH 393 to study the efficacy of agrochemicals under different irrigation levels in improving growth, yield and quality. Results of the experiment revealed that among different irrigation levels, treatment with two irrigation levels performed significantly better than other irrigation levels. Spray of salicylic acid (T4), potassium nitrate (T6) and combination of Tragacanth katira and salicylic acid (T5) significantly improved growth, quality parameters and yield of barley crop. I2 (two irrigation) among irrigation levels and T5 (combination of Tragacanth katira @ 2.5 kg ha-1 + foliar spray of SA @ 200 ppm at booting and grain formation) treatment among agrochemicals were found most productive (17.2 and 21.8 % higher grain yield over control, respectively). Protein content was improved by 20.7 and 16.4 per cent with two irrigation and combination of Tragacanth katira with salicylic acid, respectively, among irrigation levels and agrochemicals.

Key words: Irrigation, potassium nitrate, salicylic acid, Tragacanth katira
