摘要

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 1 Ox 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, P_2O_5 and K_2O Tl- FYM 100kg (End of December) T2-FYM 50Kg+N500g P_2O_5500g +K_2O500g. (End December) T3-N 1000g+P_2O_3 lOOOg+KpiOOOg (End December) T4-FYM 100kg (Early July), T5-FYM 50 Kg+N500g P_2O_5 +500 g+K_2O500g.(Early July) T6-N 1000g+P2O5 lOOOg+K_2Ol000g (Early July), T7- FYM 100kg (End September), T8- FYM 50Kg+N500g+P_2O_5 500 g+K_,O500g.(End September)T9- NlOOOg+P_O_51000g+KpiOOOg (end September) and TlO-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.
