Abstract: A field experiment entitled “Effect of moisture conservation practices under limited irrigation on yield and economics of wheat (Triticum aestivum L.)” was conducted at Agronomy Farm, College of Agriculture, Nagpur during rabi season of 2019-20. The experiment was laid out in Factorial Randomized Block Design with 12 treatment combinations, replicated thrice. The treatments consisted of three irrigation levels [One irrigation at late jointing stage (I₁), Two irrigations at crown root initiation (CRI) and flowering stages (I₂) and Three irrigations at CRI, late jointing and flowering stages (I₃)] combined with four moisture conservation practices [Control (M₀), Mulching with wheat straw (M₁), Mulching with weed biomass (M₂) and Antitranspirant spray {Kaolin @ 5%} (M₃)]. Application of three irrigations as well as wheat straw mulch at 30 DAS recorded significantly higher plant height, number of tillers hill^-1, number of leaves plant^-1, dry matter accumulation plant^-1 and relative growth rate. Yield attributing character viz. length of earhead, number of grains earhead^-1, grain weight plant^-1 and test weight along with grain, straw and biological yield of wheat were significantly higher with application of three irrigations compared to its lower levels as well as with application of wheat straw mulch at 30 DAS over rest of the respective treatments. Gross monetary returns, net monetary returns and B:C ratio also recorded the same trend.
