Field experiment were conducted to study the effect of graded levels of inorganic nitrogen in conjunction with different organics viz., coirpith, vermicompost, pressmud and biofertilizer viz., azophos on base crop rice cv. CO43 and its possible residual effect on rice fallow blackgram crop viz., blackgram var. ADT 3 at the experimental farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai nagar, Tamil Nadu. The treatments were tested in randomized block design and replicated thrice. The effect of application of 75 % RDFN + 25 % N through vermicompost + Azophos favourably influenced the yield parameters of rice – Blackgram culminating in the highest yield per hectare, which was higher than that of the control. The economic analysis of various treatments imposed revealed that application of 75 % RDFN + 25 % N through vermicompost + Azophos recorded the highest gross and net return of Rs.100804.6 and Rs.68507.6 which ultimately resulted in registering the highest net rupee invested as 3.12
