Effect of Different Levels of NPK with Farm Yard Manure on Physico- Chemical Properties of Soil, Growth and Yield of Okra (Abelmoschus esculentus L.)

The field experiment was carried out at central research farm of Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during kharif season year 2022. The experiment was comprised of 9 treatments with three level of NPK and FYM in factorial randomized block design. The treatment T9 has shown the significant results when applied 100% of NPK with FYM among the different levels of treatment combinations. Soil parameters viz. % pore space (49.25%), Water holding capacity (44.99%), % Organic carbon (0.40%), Available Nitrogen (275.36 kg ha-1), Available Phosphorus (20.49 kg ha-1), Available Potassium (225.78 kg ha-1) has shown best in treatment T9 (NPK @100% + FYM @100%) of Okra (Abelmoschus esculentus L.) in comparison to other treatment combination Yield was significantly important on in T9. Okra yield can be improved by combining NPK and Farm Yard Manure.
