Abstract

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

有机肥配激素对玉米产量和土壤生产力的影响

五种肥料的效果;采用4个重复的随机完全区组设计，研究了氮磷钾(15-15-15)、有机激素混合配方1 (HO-1)、配方2 (HO-2)、配方3 (HO-3)和颗粒有机肥(GOF)对玉米产量和土壤性状的影响。新杂交玉米(GT 822)以75 × 25 cm²的间距播种。施肥量为300 kg hm -1。初始土壤分析表明，土壤养分利用率较低，但第二季试验后土壤性质有显著改善(p≤0.05)，HO-3样地残留NPK最高，分别为0.875%、0.0275%和0.0267%。营养资料显示，HO-3肥处理的玉米株高、干物质、叶面积和叶绿素分别为270.85 cm、282.66 g、156.02 dm²和56.70。植物生长指标;HO-3的RGR、LAI和干物质利用效率分别为0.132 g g-1d -1、5.90%和34.4%。HO-3处理籽粒产量为8276.68 kg hm -1，粗蛋白质含量为8.99%，其次为HO-2和氮磷钾处理。对照和GOF的产量较低。我们的发现表明，以平衡的比例整合养分来源可以产生最大的产量，改善土壤性质，因此是规划有效肥料策略的未来方法。与综合方法或氮磷钾肥料的使用相比，依赖GOF作为玉米生产的唯一肥力组合可能会导致重大的产量损失。
