Effect of Row Spacing and Level of NPK on Growth and Yield of Fennel (Foeniculum vulgare)

An experiment was conducted at the Horticulture Research Farm, College of Horticulture, Mandsaur during the rabi season of 2013–2014 to study the effect of row spacing and NPK levels on the growth and yield of fennel. The experiment consisted of 3 levels of row spacing (30 cm, 45 cm and 60 cm) and 4 levels of NPK (0+0+0, 30+20+20, 60+40+40 and 120+60+60 kg/ha) and were evaluated under split plot design with four replications. Among various levels of row spacing tried, 45 cm row spacing exhibited significant higher growth and yield attributes and recorded significant higher seed yield (11.06 q/ha) as compared to 30 cm row spacing. Among the various NPK levels tried, 60+40+40 kg ha-1exhibited significant maximum growth, yield attributes, yield and quality of fennel. Further treatment observed significant higher seed yield 12.29 q/ha with B: C ratio of 3.45 in comparison to lower NPK levels.
