Abstract:
A field experiment was conducted during rabi season of 2013-2014 on sandy loam soil of student instructional farm (SIF) of C.S. Azad University of Agriculture & Technology, Kanpur (U.P.) to study the effect of various irrigation schedule and sulphur levels on productivity and water use efficiency of Indian mustard [Brassica juncea (L.)]. The pH of soil of experiment field was 7.3 with available N₂ 129.0, P₂O₅ 17.1 and K₂O 187 kg ha^-1. The treatment consisted of six irrigation stages IR₀ (no sown irrigation), IR₁ (30-35 DAS), IR₂ (flowering), IR₃ (30-35 DAS and flowering), IR₄ (30-35 and siliqua development) and IR₅ (30-35, flowering + siliqua development) in main plot and three levels of sulphur S₀ (no sulphur), S₁ (20 Kg ha^-1) and S₂ (30 kg ha^-1) in sub plot were tested in slit plot design (SPD) with three replications. Results showed that the maximum profit was observed with the three irrigation levels IR₅ (30-35 + F + SD) which were higher by 20.47, 25.51, 47.01, 54.65 and 123.90 percent over IR₄, IR3, IR₂, IR1 and IR0 respectively. In case of sulphur the maximum profit was observed in S₂ treatment which was higher by 4.36 and 11.71 percent then S₁ and S₀ respectively.
