A field experiment was conducted at Agricultural College, Jagtial during Rabi, 2023-24 to evaluate the effect of irrigation schedules and nano fertilizers as foliar spray in chickpea grown under zero tillage conditions. The experiment was laid out in Split plot design with 18 treatment combinations replicated thrice. The treatment includes three irrigation management viz., Residual soil moisture (no irrigation), one irrigation at pod development stage and two irrigations scheduled each at pre flowering and pod development stage as main plot treatments and six sub plot treatments as foliar nutrients viz., 100% RDF (RDF: 20-50-20 NPK kg ha^-1), 75% N+ 100% P&K + Nano urea spraying @1250 ml ha^-1 at branching initiation, 75% N & P + 100% K + Nano DAP spray @1250 ml ha^-1 at branching initiation, 100% RDF + 19-19-19 Spray @ 0.5% at branching initiation, 100% RDF + Urea Spray @ 2% at branching initiation and 100% RDF + DAP Spray @ 2% at branching initiation in sandy clay loam soil. Results revealed that, irrigations scheduling at pre-flowering and pod development recorded significantly higher plant height (41.33 cm), dry matter production (521.5 g m^-2), leaf area index (1.32), number of pods plant^-1 (30.56), 100 seed weight (27.94 gm), seed yield (1,874 kg ha^-1) and haulm yield (4,594 kg ha^-1). Among the foliar nutrients application of 100% RDF + 19-19-19 Spray @ 0.5% at branching initiation had shown significantly higher plant height (43.21 cm), dry matter production (544.9 g m^-2), leaf area index (1.41), number of branches plant^-1 (14.11), number of seeds pod^-1 (32.24), 100 seed weight (29.94g), number of pod plant^-1 (1.30), seed yield (1,943 kg ha^-1) and haulm yield (4,732 kg ha^-1).
