Our study from an ongoing research experiment initiated in Rabi 1967 at the Research Farm of CCS Haryana Agricultural University, Haryana, India, reports that during the 51st wheat cycle in pearl millet-wheat sequence, adding FYM in both seasons significantly impacted various soil parameters at different wheat growth stages compared to the rabi season. The application of 15 t of FYM ha resulted in a considerable increase in dissolved organic carbon content (9.1-11.2%), available P (9.7-12.1%), and available S (12.6-17.1%), DHA levels by 7.3-22.0%, urease activity (10.1 and 17.0%), β-Glucosidase activity (6.2-8.4%), and APA activity (5.2-10.6%), compared to 10 t FYM ha. Application of N exhibited a considerable improvement in DHA (11.0-23.2%), β-Glucosidase (9.4-19.2%), urease (13.3-28.3%), and APA (3.3-6.2%) activity compared to control (N). At stage 3, the box plot revealed that 50% of the available N, P, and S values varied from 223.1 to 287.9 kg ha, 53.0 to 98.2 kg ha, and 50.0 to 97.6 kg ha, respectively. Principal component analysis, with PC1 explaining 94.7% and PC2 explaining 3.15% of the overall variability, and SOC had a polynomial relationship with soil characteristics (R = 0.89 to 0.99). Applying FYM × N treatment during both seasons proved beneficial in sustaining the health of sandy loam soil in North-West India.
我们的研究来自于 1967 年拉比在印度哈里亚纳邦农业大学 CCS 研究农场启动的一项正在进行的研究实验，报告称在珍珠粟-小麦序列的第 51 个小麦周期中，与拉比季节相比，在两个季节添加 FYM 显著影响了不同小麦生长阶段的各种土壤参数。应用 15 吨 FYM/公顷导致溶解有机碳含量（9.1-11.2%）、有效磷（9.7-12.1%）和有效硫（12.6-17.1%）、DHA 水平（7.3-22.0%）、脲酶活性（10.1 和 17.0%）、β-葡萄糖苷酶活性（6.2-8.4%）和 APA 活性（5.2-10.6%）显著增加，而 10 吨 FYM/公顷则应用 N 导致 DHA（11.0-23.2%）、β-葡萄糖苷酶（9.4-19.2%）、脲酶（13.3-28.3%）和 APA（3.3-6.2%）活性显著提高与对照（N）相比。在第 3 阶段，箱线图显示，可用 N、P 和 S 值的 50%变化范围分别为 223.1-287.9、53.0-98.2 和 50.0-97.6 千克/公顷。主成分分析表明，PC1 解释了 94.7%的总体变异性，PC2 解释了 3.15%，SOC 与土壤特性呈多项式关系（R=0.89-0.99）。在两个季节应用 FYM×N 处理有利于维持印度西北部沙壤土的健康。
