Abstract:
A field experiment entitled Effect of irrigation scheduling on growth and yield of late sown wheat (Triticum aestivum L.)’’ was conducted during Rabi season of 2020-21 at Agricultural Research Farm of Faculty of Agricultural Sciences and Allied Industries, Rama University, Kanpur Nagar, U.P. The soil of experimental site was clay loam in texture, low in organic carbon (0.40%), available nitrogen (166.53 kg ha^-1) and medium in available phosphorus (18.73 kg ha^-1) and potash (266.27 kg ha^-1) with slightly alkaline in reaction (8.2 p^H). The conducted field experiment was comprised 9 treatments of irrigation scheduling viz. 0.8 IW/CPE ratio (I₁), 1.0 IW/CPE ratio (I₂), One irrigation at CRI stage (I₃), Two irrigations at CRI & Late jointing stage (I₄), Two irrigations at CRI & Tillering stage (I₅), Three irrigations at CRI, Late jointing & Milking stage (I₆), Three irrigations at CRI, Late jointing & Flowering stage (I₇), Four irrigations at CRI, Maximum tillering, Late jointing & Milking stage (I₈), Five irrigations at CRI, Maximum tillering, Late jointing, Flowering & Milking stage (I₉). The experiment was framed in randomized block design with three replications. All plots of experiment was equally fertilized with recommended dose of fertilizers (150:60:40 kg ha^-1 NPK). The source of nitrogen, phosphorus and potassium were urea, di-ammonium phosphate and murate of potash respectively. The result of conducted field experiment revealed that among all the irrigation schedules 1.0 IW/CPE ratio found significantly superior in all terms of plant characters viz. growth, yield attributing and yield characters. The significantly maximum grain yield 2450 kg ha^-1 and straw yield 2842 kg ha^-1 were recorded under the irrigation schedule of 1.0 IW/CPE ratio (I₂). The maximum gross monetary return (Rs.66,248 ha^-1) and net monetary return (Rs.34748 ha^-1) and benefit cost ratio (1.10:1) were recorded under the irrigation schedule of 1.0 IW/CPE ratio (I₂).
