Integration of inorganic and organic fertilizer is a very important tool for sustainable production of tomatoes contributing to human health. There were six treatments followed the design of RCBD with three replications to observe the growth, yield and the nutritional quality like lycopene and β-carotene of tomato. Treatments were; F1: Control, F2: Pond sediments-100%, F3:50%F2+50%F6, F4:50% F2+50%F5, F5: soil test based (STB) nitrogen as urea, and F6: vermicompost-100%. Statistically significant variations were found for the plant growth and yield. The highest growth and yield performances were found from the treatment F4. Fruit clusters, fruit numbers and fruit weight per plant were found highest in the treatment F4, whereas the lowest was found in the control. The highest marketable yield of tomato (96.17 t/ha) was obtained from the treatment F4 which was 20%, 29%, 13%, and 41% higher compared to F5, F2, F6, and F1 treatments, respectively. The highest amount of lycopene (67.31 ppm) and β-carotene (53.52 ppm) were found from F4 and F6, respectively, whereas the lowest amount was 42.59 ppm lycopene and 13.85 ppm β-carotene from F5 and F1, respectively. Inorganic and organic fertilizer like pond sediments can be applied for the sustainable production of tomato with friendly environment.
