 Abstract

A study was undertaken at the Farming System Research and Development (FSRD) site, Kadamshahar, Godagari, Rajshahi during 2011-2012 to find out an optimum and economic fertilizer dose for tomato in High Barind Tract. The treatments were T1: Soil test based (STB) fertilizer dose for high yield goal, T2: T1 + 25% N, T3: T1 + 25% NP, T4: T1 + 25% NK, T5: T1 +25% PK, T6: T1 + 25% NPK, T7: 75% of T1 and T8: control. The yield and yield components of tomato were significantly influenced by the different doses of fertilizer. Treatment T6 produced the maximum fruit yield of tomato (55.79 t ha-1) which was 312.95% higher than control. The lowest fruit yield (13.51 t ha-1) was recorded in T8 treatment. The highest marginal product value of Tk. 422800 ha-1 was obtained from T6 treatment. The highest marginal benefit-cost ratio over control (17.08) was also obtained from T6 treatment. So, STB fertilizer dose along with 25%NPK for high yield goal (N166P38K53S12Zn1.06B0.5 kg ha-1) was found optimum and economically profitable for tomato in High Barind Tract soil.

Key words: Fertilizer, Tomato and Yield.
