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.
