Abstract
A Field investigation was carried out at the Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai Nagar during March-June 2023 to study the response of conjoint application of inorganic fertilizer and organic manure along with foliar application of plant growth promoting rhizobacteria, respectively on the growth and yield of sorghum (Sorghum bicolor L.) under irrigated conditions. The experiment was laid out in randomized block design (RBD) with ten treatments and replicated thrice by using the sorghum variety (K12). The treatments comprised of T1- Absolute control (without application), T2 - 100% (recommended dose of fertilizer 90:45:45 kg ha-1 of N, P, and K), T3-125% recommended dose of fertilizer, T4 - 150% Recommended dose of fertilizer, T5- 100% recommended dose of fertilizer + enriched farmyard manure (EFYM), T6 - 125% Recommended dose of fertilizer + enriched farmyard manure (EFYM), T7 - 150% Recommended dose of fertilizer + enriched farmyard manure (EFYM), T8 - 100% Recommended dose of fertilizer + enriched farmyard manure (EFYM) + plant growth- promoting rhizobacteria (PGPR), T9 - 125% recommended dose of fertilizer + enriched farmyard manure (EFYM) + plant growth-promoting rhizobacteria (PGPR), T10- 150% recommended dose of fertilizer + enriched farmyard manure (EFYM) + plant growth- promoting rhizobacteria (PGPR). The results of the experiment revealed that application of 150% recommended dose of fertilizer + enriched farmyard manure (EFYM) + plant growth- promoting rhizobacteria (PGPR) significantly influenced the growth, yield attributes and yield of sorghum under irrigated condition.
