A field experiment was conducted during rabi season 2019-20 at Rajasthan College of Agriculture, MPUAT, Udaipur (Rajasthan), to evaluate the effect of different irrigation and silicon levels on wheat productivity. Results revealed that three irrigations given to wheat crop improved growth characters viz., plant height (45.42, 80.71 cm) at 50 and 75 DAS, dry matter accumulation (27.49 g) at 50 DAS as compare to other treatments. Days to 50 per cent heading (73.25) and maturity (107.33) also increase with three irrigations but statistically non significant with two irrigations. Advanced performance of yield attributes with three irrigations resulted in significant increased in grain yield (4297 kg ha-1) and harvest index (38.92 %), it reflected economics of crop and the highest net return (₹67180 ha-1) and B- C ratio (1.99) were obtained. Amongst different levels of silicon, 200 kg ha-1 increased plant height, dry matter accumulation, days to 50 per cent heading and maturity but statistically non significant with 150 kg ha-1.Increasing levels of silicon up to 200 kg ha-1also improved yield attributes i.e., effective tillers (43.28 0.5 m row length), grains ear-1 (42.75), weight of grains ear-1 (1.76 g), ear length (7.34 cm) and test weight (40.79 g) compare to control. The maximum grain yield (3824 kg ha-1), harvest index (37.30 %) and economics i.e., net return (₹ 58770 ha-1) and B-C ratio (1.79)were obtained under silicon 200 kg ha-1which was statistically at par with 150 kg ha-1 but superior over rest of treatments.
