Effect of Organic and Inorganic Fertilizers on Growth and Yield of Burly Tobacco (Nicotiana tabacum L.)

Abstract

A field experiment was carried out at Abu Jarash Farm, Faculty of Agriculture, Damascus University during the summer season of 2015 to evaluate the effect of different sources of organic manure in combination with inorganic fertilizers on growth and productivity of burley tobacco (Var. Burley-21) using 8 treatments of different organic sources and inorganic fertilizers, in addition to the control (without fertilizers). The experiment was designed according to the complete randomized block design (RCBD) with four replications.

         The statistical analysis results showed superiority of the treatment (T5:50% of the recommended dose of fertilizers through vermicompost + 50% through inorganic fertilizers + PSB) in plant height, number of leaves, leaf area, crop growth rate, fresh and cured leaf yield throughout different growth stages, where recorded (147.0 cm, 24.0 leaf. plant^-1, 14318 cm².plant^-1, 2,97 g.m^-2.day^-1, 10150 kg. ha^-1 and 1416 kg.ha^-1 respectively) at harvesting stage as compared with other organic and inorganic fertilization and control treatments. It is recommended to apply vermicompost manure in combination with inorganic fertilizers and phosphorus solubilizing bacteria to obtain higher yield of burley tobacco
