Influence of organic and inorganic sources of nitrogen on growth and yield of brinjal (Solanum melongena L.)

Abstract

A field experiment was conducted at Adhiparasakthi Agricultural and Horticultural College, Kalavai during Rabi, 2014 to evaluate the influence of organic and inorganic sources of nitrogen on growth and yield of brinjal (Solanum melongena L.). The experimental design was in a Randomized Block Design (RBD), block of 11 treatment replicated thrice using CO 2 Brinjal (Solanum melongena L.) as test crop. The growth characters, viz., Plant height (cm), No. of leaves plant-1, No. of branches plant-1, No. of flowers plant-1 and Yield attributes like total no. of fruits plant-1, Fruit weight (g), Fruit length (cm), Fruit diameter (cm), yield (kg ha-1) were significantly increased by the application of 75% N through inorganic (163.04 kg urea) + 25% N through organic (2.5 t ha-1 vermicompost) which was on par with T11 (50.60 cm) that received 50% N through inorganic (108.7 kg urea) + 50% N through organic (5 t ha-1 vermicompost) and T4 (48.73 cm) that received 75% N through inorganic (163.04 kg urea) + 25 % N through organic (5 t ha-1 FYM). Over all, from the experimental results, it could considered that application of 75% N through inorganic (163.04 kg urea) + 25% N through organic (2.5 t ha-1 vermicompost) as a better option for achieving higher productivity and profitability of Brinjal.
