The commandment of bikkurim - bringing the first fruits to the Holy Temple, opens Ki Tavo.

It is basically the final commandment of Torah and the first commandment to be performed upon entering the land.

Coming upon the heels of the commandment to remember Amalek by blotting out his memory, bringing the first fruits is the ultimate expression of acknowledgment of G-d's presence.

Thus it is the most perfect vehicle for obliterating Amalek's dark message of G-dlessness in the world.
