Abstract
A field experiment was conducted during the rabi seasons of 2023-24 and 2024-25 to assess the mulching and agro-chemicals on plant population and growth of wheat at the Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment was laid out a split-plot design with four mulching levels in main plots (No mulch, 2 t mulch ha-1, 4 t mulch ha-1, 6 t mulch ha-1) and five agro-chemicals treatments in sub-plots (control, KCl 0.2%, CalCl2, 0.1 %, Salicylic acid 100 ppm, Thiourea 100 ppm) replicated thrice. Results indicated that growth parameters were significantly influenced by mulching levels. 4 t mulch ha-1 recorded the highest plant population growth (15.65), plant height (45.62, 76.66 and 88.91cm) and dry matter accumulation (16.58, 35.41 and 46.36g plant-1). Among agro-chemicals treatment application of salicylic 100 ppm recorded the maximum growth parameters like as plant height (44.50, 70.57 and 82.60 cm) and dry matter accumulation (15.93, 30.97 and 42.81g plant-1) followed by KCl 0.2 % and CaCl2 0.1 %.
