Abstract

Experiments were conducted to study the effect of combined application of organic manures and biofertilisers on herbage yield and quality of Indigofera tinctoria during September 2012 -13 and 2013-14 at All India Co-ordinated Research Project on Medicinal, Aromatic Plants and Betel Vine Centre, Kerala Agricultural University Thrissur, Kerala, India. The treatments included FYM 10 Mg ha-1, FYM 10 Mg ha-1 + Azospirillum (2 kg ha-1), FYM 10 Mg ha-1 + Azospirillum (2 kg ha-1) + VAM (2 kg ha-1), Vermicompost (3 Mg ha-1), Vermicompost (3 Mg ha-1) + Azospirillum (2 kg ha-1), Vermicompost (3 Mg ha-1) + Azospirillum (2 kg ha-1) + VAM (2 kg ha-1), Coirpith compost (4 Mg ha-1), Coirpith compost (4 Mg ha-1) + Azospirillum (2 kg ha-1) and Coirpith compost (4 Mg ha-1) + Azospirillum (2 kg ha-1) + VAM (2 kg ha-1). The pooled herbage yield was higher in plots with basal application of farm yard manure 10 Mg ha-1 and azospirillum 2 kg ha-1 (5691 kg ha-1). However, it was statistically on par with individual application of coirpith compost @ 4 Mg ha-1 (5542 kg ha-1) and combined application of vermicompost @ 3 Mg ha-1 along with Azospirillum 2 kg ha-1 (5304 kg ha-1). The quality as indicated by glycoside indican was more in plants which received basal application of FYM alone. The uptake of N and K were higher in treatments which recorded higher herbage yield. Due to combined application of organic manures and biofertilisers, N and K contents in the post experimental soil increased significantly, while the content of P decreased. The highest B: C ratio of 3.51 was in treatment with Farmyard manure 10 Mg ha-1 and Azospirillum 2 kg ha-1.
