Abstract: An field experiment was conducted during 2016 and 2017 to investigate the impact of integrated nutrient management on bean yield and quality characters of cocoa at existing coconut gardens, Horticultural Research Station, Ambajipeta. The study was laid out in randomized block design with ten treatment replicated thrice. The bean characters like wet bean weight of 100 beans (296.39 g), dry bean weight of 100 beans (154.92 g), bean length (2.26 mm), bean width (1.20 mm) and bean thickness (0.58 mm) were recorded highest in the trees treated with 75% RDF + 25% RDN through composted coir pith+ 50g Azospirillum + 50g PSB. The highest dry bean yield per tree of 3.57 kg and lowest pod index (15.72) was recorded in same treatment. The bean quality characters like shelling %, nib recovery % and fat % were recorded. The fat % and nib recovery % were highest in trees treated with 75% RDF + 25% RDN through composted coir pith+ 50g Azospirillum + 50g PSB with 52.43% and 85.94% respectively. However, the highest shelling % was recorded in control with 22.95%. The combined use of organic manures, bio-fertilizers and chemical fertilizers has been found not only in maintaining higher productivity but also in providing stable crop yields for sustainable crop production through integrated nutrient use. The above results indicated that, for getting higher productivity and quality, application of 75% RDF + 25% RDN through composted coir pith+ 50g Azospirillum + 50g PSB is recommended in black alluvial soil of Andhra Pradesh for higher returns.
