Influence of organo-chemical fertilizer mixed with hormones on yield of Zea mays (L.) and soil productivity

The effect of five fertilizers; NPK (15-15-15), organo-chemical hormone mixed formula 1 (HO-1), Formula 2 (HO-2), 3 (HO-3) and granular organic fertilizer (GOF) were investigated on maize yield soil properties in a Randomized Complete Block Design with 4 replications. new hybrid (GT 822) was sown at 75 x 25 cm² spacing. rate 300 kg ha-1. Initial analysis showed that the had lower nutrients but after second season trial significant (p ≤ 0.05) improvement observed properties, highest residual 0.875 %, 0.0275 0.0267 % recorded HO-3 plots. Vegetative data height, dry matter, leaf area, chlorophyll 270.85 cm, 282.66 g, 156.02 dm², 56.70, respectively also fertilizer. Plant growth indices; RGR, LAI, matter use efficiency 0.132 g g-1day-1, 5.90 34.4 best HO-3. Grain crude protein 8276.68 ha-1 8.99 HO-3, followed by HO-2 NPK. Lower yields obtained from control GOF. Our finding revealed integration nutrient sources balanced ratio produced greatest output, improved is therefore future approach to planning an effective strategy. Reliance GOF as sole fertility package for production may result losses compared integrated or
