摘要

豆科植物能够改善土壤肥力和健康，在可持续农业中发挥着重要作用。通过与土壤中的一些细菌建立共生关系，豆科植物可以通过生物固氮（BNF）提高氮（N）含量。但要最大限度地发挥这些功能，豆科植物需要更多的磷，因为磷是结核中能量转化所必需的。此外，磷对豆科作物的根系发育、养分吸收和生长也有重要作用。卡纳塔克邦维贾亚普尔达瓦德农业科学大学农学院 IFS 小组在 2019 年雨季（喀里夫季）进行了一项田间试验，研究不同有机源组合对黑禾木（Vigna mungo (L.) Hepper）磷动态的影响。在不同的处理中，施用蛭石堆肥 + ghanajeevamrutha @ 100% RDP + 根瘤菌 + PSB 的土壤可利用磷（36.30 千克/公顷）和黑穗禾对磷的吸收（16.08 千克/公顷）显著较高。这项研究证明了黑鲩通过不同有机来源获取磷的动态变化。

Effect of different organic amendments on phosphorus dynamics of blackgram (Vigna mungo)

Legumes play a significant role in sustainable agriculture through their ability to improve soil fertility and health. With a mutual symbiotic relationship with some bacteria in soil, they can improve nitrogen (N) amount through biological N-fixation (BNF). But to maximize such functions, legumes need more phosphorus (P) as it is required for energy transformation in nodules. Besides, P also plays a significant role in root development, nutrient uptake and growth of legume crops. A field experiment was conducted during rainy (kharif) season of 2019 at IFS unit, College of Agriculture, (University of Agricultural Sciences, Dharwad), Vijayapur, Karnataka to study the effect of different combination of organic sources on phosphorus dynamics of blackgram [Vigna mungo (L.) Hepper]. Among different treatments, the application of vermicompost + ghanajeevamrutha @ 100% RDP + Rhizobium + PSB recorded significantly higher soil available phosphorus (36.30 kg/ha) and uptake by blackgram (16.08 kg/ha). This study has demonstrated the dynamics of phosphorus through different organic sources in blackgram.

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.
