Effect of inorganic and biofertilizers on yield and yield attributes of papaya

Abstract

The experiment was carried out to find out the Effect of inorganic and biofertilizers on growth of gynodioecious papaya. The treatment combinations involving ten levels of T-1 Recommended dose of NPK (RDF) i.e. 250: 250:250 g/plant/year, T-2 100% RDF + PSB (50g/plant), T-3 100% RDF + Azospirillum (50g/plant), T-4 100% RDF + Azotobactor (50g/plant), T-5 75% RDF + PSB (50g/plant) + Azospirillum (50g/plant), T-6 75% RDF + PSB (50g/plant) + Azotobactor (50g/plant), T-7 75% RDF + PSB (50g/plant) + Azospirillum (50g/plant) + Azotobactor (50g/plant), T-8 50% RDF + PSB (50g/plant) + Azotobactor (50g/plant), T-9 50% RDF + PSB (50g/plant) + Azospirillum (50g/plant) + Azotobactor (50g/plant), T-10 Farmer’s Practices were given in Red Lady variety. Maximum Number of fruits per plant, Fruit weight (kg), Fruit yield (kg/plant), Fruit yield (t/ha), Fruit length (cm), Fruit width (cm), Thickness of pulp (cm), Length of fruit cavity (cm), Width of cavity (cm), Cavity index (%). were observed by the maximum at 180, 270 and 360 DAT were observed under the treatment T7- 75% RDF + PSB (50g/plant) + Azospirillumn (50g/plant) +Azotobactor (50g/plant) at all the growth stages.
