Effect of biofertilizer, manures and chemical fertilizers on fruit quality and shelf life of guava (Psidium guajava L.) cv. Allahabad safeda

Abstract

The research experiment conducted was at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand during of the year 2018 on “Effect of biofertilizer, manures and chemical fertilizer on fruit quality and shelf life of guava (Psidium guajava L.) cv. Allahabad Safeda”. The experiment was laid out in Completely Randomized Design with 09 treatments. The soil of the experimental site was loamy sand. The soil application of full dose of biofertilizers manures and chemical fertilizers were given as basal dose in last week of June and remaining half dose of chemical fertilizer given in first week of September. Among all the treatments, the soil application of 30 % RDF through chemical fertilizers + 30 % RDN through Poultry manure + 20 ml Bio NPK Consortium per tree treatment was most effective treatment and which was recorded significantly maximum total soluble solids (11.93 0Brix), reducing sugar (6.35 %), non-reducing sugar (1.72 %), total sugar (8.07 %), ascorbic acid (177.67 mg/100 g pulp). Whereas, the soil application of 40 % RDF through chemical fertilizers + 40 % RDN through Poultry manure + 10 ml Bio NPK Consortium per tree treatment was most effective treatment for extending shelf life of guava fruit and which was recorded significantly maximum shelf life (8.17 days).
