Description
Penelitian dilaksanakan di Desa Cisurupan Kabupaten Garut, Jawa Barat pada tipe tanah andosol (1.100 m dpl.) pada bulan Juni-Nopember 2002. Penelitian bertujuan untuk mempelajari pengaruh pupuk organik dan dosis NPK baik terhadap pertumbuhan maupun hasil tanaman tomat. Penelitian menggunakan rancangan acak kelompok faktorial dengan ulangan empat kali. Perlakuan terdiri dari dua faktor. Faktor pertama jenis pupuk NPK dan faktor kedua jenis bahan organik. Hasil penelitian menunjukkan tidak terdapat pengaruh interaksi antara jenis pupuk NPK dan pupuk organik. Penambahan pupuk NPK (50 kg N, 75 kg P2O5, dan 75 kg K2O per hektar) dapat meningkatkan tinggi tanaman, diameter batang, dan bobot buah total per petak. Jenis pupuk NPK yang paling efisien terhadap hasil buah tanaman tomat varietas artaloka adalah 50 kg N, 75 kg P2O5, dan 75 kg K2O per hektar. Increasing NPK fertilizer efficiency through organic material utilization on yield of tomato. The experiment was conducted at Cisurupan Village, Garut, West Java on andosol soil type (1,100 m asl) from June to November 2002. The objective of the experiment were to study the influence of organic fertilizer and kind of NPK application on the growth and yield of tomato. Factorial formula of randomized block design with four replicates was used. Treatments consisted of first factor of NPK fertilizer and second factor was kinds of manure. In fact the results indicated that there was no interaction effect between application of organic fertilizers and NPK fertilizer on both of the growth and yield of tomato. The NPK (50 kg N, 75 kg P2O5, and 75 kg K2O) fertilizer was able to increase plant height, stem diameter, and total fruit weight per plot. The most efficient NPK fertilizer formulas on artaloka tomato yield per plant and total weight was 50 kg N, 75 kg P2O5, and 75 kg K2O per hectare.
