摘要

拉贾斯坦邦科塔农业大学 Ummedganj 农业研究站在 2017-18 年至 2021-22 年冬季（蕾期）期间开展了一项田间试验，旨在为可持续小麦（Triticum aestivum L.）生产开发天然和有机养分管理技术，以改善土壤健康和农民收入保障。试验包括 8 个处理，即在 25、50 和 75 DAS 期，100% N-FYM + 10% 牛尿（CU）喷雾；在 25、50 和 75 DAS 期，50% N-FYM + 50% N-Vermicompost (VC) + 10% vermiwash (VW) 喷雾；100% N-FYM + NPK 复合肥 @1250 毫升/公顷，作为土壤施肥；75% N-FYM + NPK 复合菌群 @1250 毫升/公顷，土壤施用；75% N-FYM + NPK 复合菌群 @1250 毫升/公顷，土壤施用，同时在 25、50 和 75 DAS 期喷洒 10% 牛尿；75%氮-FYM+氮磷钾复合肥（1250 毫升/公顷）作为土壤施肥，同时在 25、50 和 75 DAS 期喷洒 10% 的 amritasanjeevani；在播种、25 和 50 DAS 期喷洒 500 升/公顷的 jeevamrut；在播种、25 和 50 DAS 期喷洒 500 公斤/公顷的 ghanjeevamrut，采用随机区组设计（RBD），重复三次。对 5 年结果的严格检验表明，芒果的株高（66.01 厘米）、分蘖/株（8.57）、干重/米行长（77.20 克）、有效分蘖/米行长（80.60）、穗长（8.93 厘米）、籽粒/穗（44.90）、试验重量（41.小麦在播种、25 和 50 DAS 期喷施 50% N-FYM + 50% N-VC fb10% vermiwash，比在播种、25 和 50 DAS 期喷施 ghanjeevamrut @500 kg/ha，以及在播种、25 和 50 DAS 期喷施 jeevamrut @500 升/ha，获得的小麦产量（3756 公斤/公顷）、总收益（100,605 `/公顷）和综合分析结果与其他处理相当。然而，在 25、50 和 75 DAS 施用 75% N-FYM+ NPK 复合肥 @1,250 毫升/公顷作为土壤肥料和 @10% amritasanjeevani 喷雾剂的情况下，小麦的净收益（63,020 `/公顷）和 B:C 比率（1.77）显著提高。土壤健康改善结果表明，在 25、50 和 75 DAS 期，施用 50% N-FYM + 50% N-VC fb10% vermiwash 喷雾剂后，有机碳（0.66%）、可利用磷、钾、硫（分别为 63.94、432.8 和 28.21 千克/公顷）和可利用锌（0.90 毫克/千克）明显增加。

Potential organic nutrient management practices for wheat (Triticum aestivum) in south-eastern Rajasthan

A field experiment was conducted during winter (rabi) seasons of 2017–18 to 2021–22 at Agricultural Research Station, Ummedganj, Agriculture University, Kota, Rajasthan to develop natural and organic nutrient management technologies for sustainable wheat (Triticum aestivum L.) production to improve soil health and income security of the farmers. The experiment comprised of 8 treatments, viz. 100% N-FYM fb 10% cow urine (CU) spray at 25, 50 and 75 DAS; 50% N-FYM + 50% N-Vermicompost (VC) fb 10% vermiwash (VW) spray at 25, 50 and 75 DAS; 100% N-FYM + NPK consortia @1250 ml/ha as a soil application; 75% N-FYM + NPK consortia @1250 ml/ha as a soil application; 75% N-FYM + NPK consortia @1250 ml/ha as a soil application fb 10% cow urine spray at 25, 50 and 75 DAS; 75% N-FYM + NPK consortia @1250 ml/ha as a soil application fb amritasanjeevani spray @10% at 25, 50 and 75 DAS; jeevamrut @500 litre/ha at sowing, 25 and 50 DAS; and ghanjeevamrut @500 kg/ha at sowing, 25 and 50 DAS, in a randomized block design (RBD), replicated thrice. A critical examination of 5 years results revealed that significantly higher plant height (66.01 cm), tillers/plant (8.57), dry weight /meter row length (77.20 g), effective tillers/meter row length (80.60), ear length (8.93 cm), seeds/ear (44.90), test weight (41.90 g), seed yield (3756 kg/ha) and gross returns (`100,605/ha) of wheat were obtained under the application of 50% N-FYM + 50% N-VC fb10% vermiwash spray at 25, 50 and 75 DAS over ghanjeevamrut @500 kg/ha at sowing, 25 and 50 DAS and jeevamrut @500 litre/ha at sowing, 25 and 50 DAS and on par with rest of treatments in pooled analysis. However, net returns (`63,020/ha) and B:C ratio (1.77) of wheat were obtained significantly higher under application of 75% N-FYM+ NPK consortia @1,250 ml/ha as a soil fb amritasanjeevani spray @10% at 25, 50 and 75 DAS. Result on soil health improvement revealed that significantly higher organic carbon (0.66%), available phosphorus, potassium, sulphur (63.94, 432.8 and 28.21 kg/ha, respectively) and available zinc (0.90 mg/kg) were recorded with the application of 50% N-FYM + 50% N-VC fb10% vermiwash spray at 25, 50 and 75 DAS.

期刊介绍： Indian Journal of Agronomy welcomes concise articles presenting original research data based on field experiments on all aspects of agronomy in different crops and related cropping systems. • The journal publishes only full length comprehensive articles based on new approaches/findings in English only. • Review articles are also considered but these are normally solicited by Editorial Board. However, the authors who wish to contribute a review on their own based on their standing in the relevant field may contact the Secretary or Chief Editor with a broad outline before submitting the manuscript.
