Effect of Row Spacing and Nitrogen Levels on Growth and Yield of Dill (Anethum graveolens L.)

Abstract

An experiment was conducted at the Horticulture Research Farm, RVSKVV College of Horticulture, Mandsaur (Madhya Pradesh) during the rabi season of 2013−2014 to study the effect of row spacing and nitrogen levels on the growth and yield of dill (Anethum graveolens L.).  The experiment consisted of 3 levels of row spacing (40×10 cm², 50×10 cm² and 60×10 cm²) and 4 levels of nitrogen (0, 25, 50 and 75 kg N          ha^-1). These treatments were evaluated under factorial Randomized Block Design with three replications. Different levels of row spacing and nitrogen significantly affect the plant height, branches, umbels, umbellate, seeds umbel^-1, days to 50% flowering, chlorophyll content in leaves, fresh and dry weight of plant, test weight, seed, straw and biological yield, harvest index, gross return, net return and B:C ratio of dill.  Among various levels of row spacing tried, 50×10 cm² row spacing exhibited significantly higher growth and yield attributes and recorded significantly maximum seed yield of 15.04 q ha^-1 which was 42.56% higher as compare to row spacing of 40×10 cm².  Among the various nitrogen levels tried, 75 kg N ha^-1 exhibited significant maximum growth, yield attributes and quality of dill. Further treatment observed significant higher seed yield of 14.48 q ha^-1 which was 57.22% higher with B:C ratio of 3.08 in comparison to other nitrogen levels (control).
