The effect of cultivar and organic enriched fertilisers on plum (prunus salicina) growth and development under high density management system

High density orchard management systems and ideal nutrition positively influence productivity in deciduous fruits. The main objective was to evaluate the effect of cultivar and organic fertilisers on plum (Prunus salicina) growth and development under high density management system of 2222 plants per hectare. The experiment was set as a 4*4 factorial in a Randomised Complete Block Design with 4 replications. Cultivars, Rosearli, Sapphire, Santarosa and Souvenir were evaluated in combination with three organic enriched fertilisers; Comp J organic, Comp C organic tobacco fertiliser, 100 % organic soil builder from Nico orgo Pvt Ltd and inorganic Compound J. Data was collected yearly on tree girth (mm), flowering dates at 50% and 100%, number fruits/cluster, mean fruit weight (mm), fruit length (cm) and fruit diameter (mm). Flowering was generally influenced by cultivar. Sapphire came into flower earlier and lastly Rosearli. Girth extension, fruit width and fruit weight differed significantly (P<0.001) with variety. Organic enriched fertilisers can be used in plum production.
