Abstract
A field experiment was conducted during the Rabi seasons of 2023-24 and 2024-25 at the Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya. To study the effect of sowing methods, irrigation scheduling, and agrochemicals application on wheat under late-sown conditions. The experiment included three sowing methods, i.e Line sowing, Furrow Irrigated Raised Bed (FIRB), and System of Wheat Intensification (SWI), Three irrigation levels, i.e 1.0 IW/CPE ratio, 0.75 IW/CPE ratio and 5 Irrigation each at (CRI, Tillering, late jointing, flowering and milking), and Three agrochemical treatments, i.e Hydrogel @ 10 kg ha-1, Salicylic acid @ 200 ppm and Hydrogel 10 kg ha-1 + Salicylic acid @ 200 ppm. Results show that the highest Dry matter Accumulation was recorded under FIRB (Furrow Irrigated Raised bed method) followed by the Line sowing and Irrigation at IW/CPE ratio 1.0 recorded significantly higher Dry matter accumulation. Furrow Irrigated Raised Bed sowing method produced the highest grain yield (45.29 and 50.34 qha{¹) followed by Line sowing method whereas Line sowing method recorded highest Straw yield and System of wheat Intensification recorded the highest harvest index (40.61 and 42.0%). Irrigation at IW/CPE ratio 1.0 recorded significantly higher enhanced growth and yield parameters compared to 0.75. The combined application of hydrogel (10 kg ha-¹) and salicylic acid (200 ppm) resulted in superior crop performance. The findings suggest that FIRB sowing combined with optimal irrigation and agrochemical application is most effective under late-sown conditions.
