Innovation in traditional organic nutrient management practices for better soilhealth and higher productivity of brahmi (Bacopa monnieri L.)

Abstract

This study was conducted at Medicinal Plants Research and Development Centre (MRDC) of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, India, to examine the effect of Jeevamrit (Bioenhancer) on soil health and herbage yield of brahmi crop (var. CIM- Jagriti) and to optimise its rate of application. The experiment was laid out in randomised block design (RBD), replicated trice. The experimental soil was sandy clay loam in texture, neutral in reaction, having pH 6.9, medium in organic carbon (0.64%), low in available nitrogen (180.78 kg ha-1) and medium in both available phosphorus (20.14 kg ha-1) and potassium (200.64 kg ha-1). Jeevamrit enhances soil nutrient content, improve bulk density and biodiversity by increasing beneficial soil microbes which mineralise the nutrients present in soil and increase their availability. Jeevamrit 4000 l ha-1 can be used as a nutrient source in place of chemical fertilisers and expensive bulky organic manures under organic nutrient management.
