Abstract
An experiment was conducted in a private fields in Alhaidariy Al-Najaf Government , to study the effect of adding biofertelizer (Azotobacter) and spraying nitrogen fertilizer on growth parameters and yield of Ocimum basilicum L. c.v Purple during 2014 and 2015 seasons. Three levels of Biofertelizer ( Azotobacter )(0,5,10)g.100seeds-1 and spray three concentrations of nitrogen (46% urea), (0,100,200) mg.l-1. Experiment was adopted as 3x3 in Randomized Complete Block Design R.C.B.D. with three replicates Means were compared according to Duncan Multiple Range test at the level 0.05of probability . Results showed that superiority of the treatment of addition biofertelizer (Azotobacter) at level 10g.100seeds-1 and spraying nitrogen fertilizer at concentration of 200 mg.l-1 in plant length (48.58 and 49.97) cm . plant -1 , total leaf area (23.10 and 23.37) cm2.plant -1, dry weight of vegetative part (12.28 and 12.42) g. plant -1, chlorophyll content (74.81and 73.20) mg.100g -1, nitrogen % (2.64 and 2.33 %) , total yield per unit area (3.42 and 2.57) ton.h-1 in the two seasons 2014 and 2015 respectively as compared to control treatment which gave the lowest values.
