Afield experiment was conducted at College of Agriculture, Vellayani, Thiruvananthapuram, Kerala to find out the effect of organic nutrition on chemical and biological properties of the red loam soils under baby corn cultivation. Treatments comprised different sources of organic nutrition such as vermicompost, coirpith compost and poultry manure along with in situ green manuring and biofertilizer (PGPR mix I) application. In the control treatment inorganic fertilizers (NPK 135:65:45 kg/ha) were applied. Poultry manure application along with in situ green manuring recorded higher available N content in soil after the experiment while poultry manure with application of PGPR mix I recorded higher available P content. The available potassium content of soil was higher when vermicompost was applied along with PGPR mix I. Application of organic manures together with biofertilizer (PGPR mix I) resulted in enhanced microbial activity in the soil.
