Corn is native to the tropics and an important food ingredient because it is the third source of carbohydrates in the world after wheat and rice. Apart from being a food commodity, corn can also be categorized as a vegetable when it is harvested before pollination occurs or has not yet produced seeds, commonly called baby corn. Baby corn is a very profitable alternative for farmers due to short harvest time, high demand, and high nutrition. A research was conducted in the experimental garden of the Faculty of Agriculture, Kadiri University, Kediri. The environmental design used was factorial randomized block design (RBD). The total treatment was 16 treatment combinations which were repeated three times so that there were 48 experimental units. The treatment in the experiment was a combination of two factors, namely the corn cultivar factor which consisted of four levels and the corn population factor which also consisted of four levels. The CPI-2 variety was highly suitable for narrow spacing with high plant density. The CPI2 variety was able to show the highest yield on weight parameters with and without husks compared to other varieties. This was able to increase productivity per unit area of land.
Jagung merupakan tanaman asli daerah tropika, jagung termasuk sumber karbohidrat ketiga setelah gandum dan beras yang menjadikannya komoditas pangan penting. Selain sebagai komoditi pangan, jagung juga dapat dikategorikan sebagai sayuran ketika di panen sebelum terjadi penyerbukan atau belum menghasilkan biji, biasa disebut jagung semi (Baby corn). Jagung semi menjadi alternatif yang sangat menguntungkan bagi petani karena waktu panennya sangat singkat, permintaan tinggi, dan gizi yang tinggi. Penelitian dilakukan di lahan percobaan milik Fakultas Pertanian, Universitas Kadiri, Kediri. Penelitiaan dilakukan menggunakan Rancangan Acak Kelompok (RAK) faktorial. Perlakuan pada percobaan adalah kombinasi dua faktor, yaitu faktor kultivar jagung semi yang terdiri atas empat taraf dan faktor populasi tanaman yang juga terdiri atas empat taraf. Total perlakuan terdiri dari 16 kombinasi perlakuan dengan ulangan sebanyak tiga kali sehingga didapat 48 satuan percobaan. Varietas CPI-2 sangat cocok dengan jarak tanam rapat dan kerapatan tanaman yang tinggi. Varietas CPI-2 mampu menunjukkan hasil tertinggi pada parameter bobot tongkol berkelobot maupun tanpa kelobot dibanding varietas lainnya. Hal tersebut dapat meningkatkan produktivitas per satuan luas lahan.Â
