Abstract


ABSTRAK. Salah satu usaha peningkatan produksi tomat adalah dengan mencari kultivar unggul yang cocok pada berbagai lokasi dengan jenis tanah yang berbeda. Percobaan ini dilaksanakan di Kebun Percobaan Wera, Subang dari bulan September sampai dengan Desember 2005, pada ketinggian 100 m dpl. Percobaan menggunakan rancangan acak lengkap dengan pola faktorial, terdiri dari 2 faktor (kultivar Intan dan Mutiara) dan 4 jenis tanah (Andosol Lembang, Latosol Jalancagak, Latosol Subang, dan Aluvial Sukamandi) di mana setiap perlakuan diulang 4 kali. Tujuan percobaan adalah, mengetahui pertumbuhan kultivar Intan dan Mutiara yang cocok dan berproduksi baik pada jenis tanah tertentu. Hasil percobaan menunjukkan adanya interaksi antara kultivar dan jenis tanah terhadap bobot buah. Kultivar tomat berpengaruh nyata terhadap perbedaan tinggi tanaman, jumlah cabang, diameter batang, jumlah bunga, dan buah. Kultivar Mutiara memperlihatkan pertumbuhan vegetatif dan hasil yang lebih baik. Hasil tertinggi tomat Mutiara pada jenis tanah Andosol Lembang yaitu sekitar 1,8 kg/tanaman.

ABSTRACT. Sutapradja, H. 2008. The Growth and Yield of Intan and Mutiara Tomato Cultivar on Several Type of Soil. One of the effort to increase tomato production is the use of superior cultivar which is adaptive to various locations with different types of soil. The experiment was conducted at Wera, Subang Experimental Garden from September until December 2005, with the elevation 100 m asl. The experiment used a factorial completely randomized design, consisting of 2 factors, i.e. the cultivars (Intan and Mutiara) and soil types (Andosol Lembang, Latosol Jalancagak, Latosol Subang, and Aluvial Sukamandi), with 4 replications. The experiment was conducted to determine the tomato cultivars which gave highest yield for the certain soil type. The results showed that there was interaction between cultivar and soil type on fruit weight per plant. While cultivar was significantly affect plant height, branch number, stem diameter, cluster number, flower number, fruit weight, and fruit number per plant. Mutiara cultivar gave better growth and yield compare to Intan cultivar. The highest yield of Mutiara cultivar (1,8 kg/plant) was achieved by Lembang Andosol soil type.
