Results showed superiority concentration 8m.L-1 Humus addition treatment gave increscent in fruit weight, length, flesh weight and N concentration. The effect of the interaction has exceeded the treatment of interaction between 8 ml. L-1Humus and 8 ml. L-1 seaweed extract in both the fruit weight and % of total nitrogen, while the treatment of the mixture was 4 ml. L-1Humus and 8 ml. L-1. A seaweed extract in the fruit-length ratio, while the interaction treatment exceeded 8 ml. L-1. Humus and 0 ml.
