Penelitian ini bertujuan untuk menentukan geometri tanaman terbaik bagi pertumbuhan dan hasil dua varietas jagung. Penelitian ini dilaksanakan di Kebun Pendidikan Penelitian dan Pengembangan Pertanian (KP4) Universitas Gadjah Mada di Kalitirto, Berbah, Sleman, Yogyakarta mulai Desember 2003 sampai Maret 2004. Perlakuan percobaan diatur dalam Rancangan Petak Terbagi dengan empat ulangan. Varietas jagung sebagai petak utama terdiri atas varietas Pioneer 11 dan varietas Bisma. Geometri tanaman sebagai anak petak terdiri atas : geometri empat persegi panjang (panjang dan lebar sisi yaitu 75 cm dan 20 cm), geometri bujur sangkar (panjang sisi 38,73 cm), dan geometri heksagonal (panjang sisi dan jarak antar tanaman 38,73 cm). Hasil penelitian menunjukkan bahwa : (1) pertumbuhan dan hasil jagung dengan geometri heksagonal lebih tinggi dibandingkan dengan geometri empat persegi panjang dan bujur sangkar, dan (2) pertumbuhan dan hasil jagung varietas Pioneer 11 lebih tinggi dibandingkan dengan varietas Bisma.

The present experiment was conducted to determine the best plant geometry to growth and yield of two corn varieties. It was done in the experimental field of Agricultural Training, Research and Development (ATRD), Gadjah Mada University, located in Kalitirto, Berbah, Sleman, Yogyakarta from December 2003 to March 2004. Experimental treatments were arranged in split plot design with four replications. Corn variety as the main plot, that was Pioneer 11 Variety and Bisma variety. The Plant geometry as the sub plot, that was rectangle geometry (straightedge length and width were 75 cm and 20 cm ), square geometry (straightedge length 38,73 cm), and hexagonal geometry (straightedge length and the distance between plants were 38,73 cm). Experimental results showed that : (1) growth and yield of geometry hexagonal higher than rectangle and square geometry, and (2) growth and yield of Pioneer 11 variety higher than Bisma variety.
