Abstract
The study was conducted in the Farm of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh during the period from November 2009 to January
2010 to study the effect of nitrogen on growth and yield of turnip. The
experiment consisted of four different levels of nitrogen (N0: 0 kg
N ha-1 (control); N1: 40 kg N
ha-1; N2: 70 kg N/ha and N3: 100 kg N ha-1)
with 3 replications. Data on different growth parameter and yield showed
statistically significant differences among different treatment. Results showed
that at 20, 30, 40, 50 DAS and at harvest, the tallest plant (11.9 cm, 22.6 cm,
34.8 cm, 58.4 cm and 60.8 cm, respectively) was recorded from N2 whereas
the shortest plant (10.1 cm, 18.5 cm, 27.3 cm, 48.6 cm and 51.3 cm,
respectively) was recorded from N0. The highest diameter of root
(3.7 cm) and highest yield per hectare (25.8 tons) were recorded from N3 and,
the lowest diameter (2.9 cm) and lowest yield (18.8 ton) were recorded from N0.
