Effect of different levels of nano fertilizer and FYM on soil physico-chemical properties and yield of mustard (Brassica juncea L.)

A field experiment was conducted during the Rabi season 2024-25 at Research Farm, Department of Soil Science and Agricultural Chemistry, NAI, SHUATS, Prayagraj (UP) on sandy loam soil to investigate the effect of nano fertilizer and FYM on soil physico-chemical properties and yield of mustard. The factors include 4 levels of nano fertilizer viz. 0%, 35%, 75% and 100% and 3 levels of FYM viz. 0 t/ha, 12.5 t/ha and 25 t/ha. The experiment was laid out in randomized block design with twelve treatments replicated thrice. Study revealed that the application of different levels of nano fertilizer and FYM significantly influenced soil physico-chemical properties as well as yield of mustard. Treatment T₁₂ (Nano fertilizer @ 100% + FYM @ 25 t/ha) significantly enhanced percent pore space, WHC (%), OC (%) and available nutrients NPK (Kg/ha).
