Effects of Organic Manures and Bio-Fertilizers on Soil Properties, Productivity and Nutrients Uptake of Indian Mustard

Abstract

A field experiment was conducted during the Rabi season 2020-21 to study the effect of organic manures and bio-fertilizers on soil properties, productivity and nutrient uptake of Indian mustard at Deendayal Upadhyay Centre of Excellence for Organic Farming (DDUCE-OF), CCS Haryana Agricultural University, Hisar. The experiment comprised of eight treatments involving Farm Yard Manure (FYM), Vermicompost (VC) and Poultry Manure (PM) alone and along with bio-fertilizers (BF), an absolute control and a cow-based formulation treatment. The results revealed that the treatment 100% RDN through PM+BF produced significantly higher seed and stover yield of mustard which was at par with treatment 100% RDN through VC+BF and 100% RDN through FYM+BF as compared to other treatments. Maximum seed (29.84 q ha-1) and stover (74.75 q ha-1) yields were received under treatment 100% RDN through PM+BF which was 27.5 % and 16.7 % higher over the control, respectively. Similarly, highest total NPK uptake (116.2 kg ha-1 for total N, 19.9 kg ha-1 for total P and 83.5 kg ha-1 for total K) were recorded in the treatment 100% RDN through PM+BF. The highest soil restorative effect on soil organic carbon (0.67 %), available N (162 kg ha-1), available P (13.7 kg ha-1) and available K (280 kg ha-1) were also observed under treatment 100% RDN through PM+BF. These organic amendments such as FYM, vermicompost, poultry manures alone and along with bio-fertilizers, had significantly improved the seed and stover yields as well as uptake of nutrients by Indian mustard.
