Effect of inorganic and organic fertilizers along with Azotobacter on growth, yield and quality of Kinnow mandarin

A study was conducted during 2013 and 2014 on the effect of integrated use of inorganic and organic fertilizers (vermicompost) along with bio-inoculants on plant growth, yield and quality of Kinnow mandarin. Vegetative growth parameters like plant height and canopy volume showed maximum increase with cent per cent nitrogen through urea augmented with Azotobacter. Replacing 25 per cent of nitrogen in the form of vermicompost resulted in maximum number of fruits, fruit weight, fruit volume, fruit length and width and fruit yield. TSS, Total sugars (reducing and non-reducing) and ascorbic acid contents of the fruits improved with the integrated application of vermicompost along with inorganic fertilizers and biofertilizers.
