Growth and yield maximisation of baby corn (Zea mays L.) as influenced by integrated nutrient management practices and foliar nutrition

Abstract

Field experiments were conducted to study the effect of graded levels of inorganic nitrogen in combination with various sources of organic manures and panchagavya foliar spray on hybrid baby corn G-5414 at the Experimental farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalainagar, Tamil Nadu. The treatments were tested in RBD and replicated thrice. The effect of application of 100% recommended dose of nitrogen as inorganic + Vermicompost @ 5 t ha-1 + 3 sprays of 3% panchagavya favourably influenced the yield parameters of baby corn culminating in the highest baby corn yield per hectare, which was higher than that of the control. The economic analysis of various treatments imposed revealed that application of 100% recommended dose of nitrogen as inorganic + Vermicompost @ 5 t ha-1 + 3 sprays of 3% panchagavya recorded the highest gross and net return of Rs.147400 and Rs.98287 which ultimately resulted in registering the highest net rupee invested as 3.00.
