ABSTRACT
The present experiment was conducted at College of Agriculture, Vellayani during 2016-2018, for studying the effect of organic manures and biofertilizers on plant and soil nutrient status before and after the cultivation of papaya (cv. Surya). Soil nutrient status was analysed before and after the experiment and the study revealed that application of 75% recommended dose of Nitrogen as organic along with AMF to papaya plants significantly increased the nitrogen, phosphorus and potassium content in the soil. The micronutrient content (Cu, Fe, Mn, Zn) and microbial count (bacteria, fungi and actinomycetes) were found to be highest with the application of 100% recommended dose of nitrogen as organic along with AMF. Plant analysis of papaya revealed that the phosphorus, potassium and micronutrient content of the leaf petiole was found to be maximum with the application of 100% recommended dose of nitrogen as organic along with PGPR Mix-1 and AMF.
Key words :
AMF, Biofertilizers, Organic manures, Papaya, PGPR MIX-1, Soil nutrient status.
