Significant variation was found in respect of
marketable yield of root by different levels of
nitrogen. The marketable yield of root increased
with increasing N up to a certain level and then
decreased (Table 2). The maximum marketable
yield of root (20.67 t/ha) was found from the
treatment of N2 while the minimum was in N0
(11.58 t/ha). Patil and Gill (1981) stated that the
yield depended on the quantity of nitrogen
fertilizer and it was the highest when 300 kg of
nitrogen per hectare was applied.
