A field experiment was conducted at Taridalu village, Gowribidanur taluk during Rabi season of 2005, on sandy clay loam soil to study the effect of organic sources of nutrients viz. FYM, compost and vermicompost along with inorganic fertilizers with and without Rhizobium on quality and yield of French bean. The effect of integrated nutrient management on crude fiber, ascorbic acid, titrable acidity and total sugars was significant. However, crude protein content was non significant. Higher crude protein content of French bean was recorded in compost treated plots. Among different treatments, treatment received compost @ 25 t ha-1+ RDF (recommended dose of fertilizer @ 62.5:100:75 kg ha-1) without Rhizobium recorded the highest crude protein content of 22.58 percent. Similarly, highest value of ascorbic acid (22.26%) and lowest crude fiber (1.58%) was recoded in the same treatment. Application of vermicompost @ 10t ha-1 + RDF registered highest value of titrable acidity (0.162%) followed by the application of compost @ 25 t ha-1 recorded maximum value of total sugars (6.95%) which was on par with treatment compost @25t ha-1 + RDF. Among different treatments, compost received plots showed superior quality of pods besides improving nutrient or mineral concentrations of French bean and FYM @ 25 t ha-1 + RDF treatment registered the maximum yield of French bean (133.51 q ha-1) with highest net income.
