An experiment was carried out to study the effect of different organic manures (vermicompost, farm yard manure, neem cake, mustard cake and mahua cake) on ‘Mosambi’ sweet orange trees aged 8 years at the Horticultural Research Station of Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India during 2008 and 2010. The experiment was conducted considering eleven treatments including control (recommended rate of fertilizer 400:300:400 g/plant/year) and all the treatments were replicated thrice. Among different organic manures, vermicompost at 20 kg/tree resulted maximum plant growth (spread and height) with quality fruits in respect of total soluble solids and vitamin C content but FYM at 40 kg/tree treated plants produced fruits with maximum total sugar content. However, highest yield and maximum sizeable fruits were obtained when the plants were treated with neem cake at 7.5 kg/tree. The avialable nitrogen content of soil was found to be higher (73.39 and 66.32 kg ha-1) with vermicompost and mustard cake at higher doses. Optimum leaf nitrogen (2.22%) and potassium (1.56%) were obtained with neem cake treatment. It can be concluded that vermicompost and neem cake can be applied for higher vegetative growth and higher production of quality fruits in ‘Mosambi’ sweet orange in West Bengal.
