Effect of inorganic fertilizers, organic manure and their time of application on fruit yield and quality in mango (Mangifera indica) cv. Dushehari

Abstract

The experiment was conducted at Punjab Agricultural University, Regional Fruit Research Station, Bahadurgarh, Patiala on 15-years old mango trees of cultivar Dushehari planted at 10x 10 m. to study the effect of different levels of inorganic fertilizers, organic manure and their time of application on yield and quality of mango fruit Cv. Dushehari. There were ten treatments for this research experiment that included different levels of FYM, N, P2O5 and K2O T1- FYM 100kg (End of December) T2-FYM 50Kg+N500g P2O5500g +K2O500g. (End December) T3-N 1000g+P2O5 1000g+K2O1000g (End December) T4-FYM 100kg (Early July), T5-FYM 50 Kg+N500g P2O5 +500 g+K2O500g.(Early July) T6-N 1000g+P2O5 1000g+K2O1000g (Early July), T7- FYM 100kg (End September), T8- FYM 50Kg+N500g+P2O5 500 g+K2O500g.(End September)T9- N1000g+P2O51000g+K2O1000g (end September) and T10-Control. The results of the experiment showed that maximum fruit yield (66.85 kg/plant) and maximum number of fruits (347/tree) were obtained with the application of 50 kg. farm yard manure along with 500 g each of nitrogen, phosphorus and potassium per tree in the month of September before flower bud differentiation.
