Abstract
The study was conducted
at the farm of Bangabandhu Sheikh Mujibur
Rahman Agricultural University, Gazipur, Bangladesh during
the period of November to December, 2010 to enhance the production of spinach (Beta vulgaris cv. BARI spinach through
the improvement of growth and yield by optimizing the appropriate levels of
nitrogen fertilizer. The experiment was laid out in a Randomized Complete Block
Design (RCBD) comprising six treatments with four replicates each. The
treatment combinations were T0 (0 kg N ha-1), T1
(50 kg N ha-1), T2 (75 kg N ha-1), T3 (100
kg N ha-1), T4 (125 kg N ha-1) and
T5 (150 kg N ha-1), respectively. Data on
plant height, leaf number, root-shoot growth followed by fresh and dry weight
along with yield and benefit cost ratio (BCR) confirmed that nitrogen
fertilizer applied at the rate of 75 kg N ha-1 had a significant
(p<0.01) effect on short term growth and yield of spinach.
