At the probability level, similar letters do not statistically vary from one another. Nitrogen, phosphorus, sulfur, and boron are combined to form NPSB. Vermicompost is VC. NPSB cost ha−1 = 15 ETB; cost of application of both fertilizers (NPSB and vermicompost) ha−1 = 0.5 EYB; Selling price of tomato fruit per kg = 10 ETB.
