<p><em>Penelitian ini bertujuan untuk mempelajari pengaruh sistem tanam alur dan pemberian jenis pupuk terhadap pertumbuhan dan produksi kacang tanah (Arachis hypogaea L.). Penelitian dilaksanakan di KP Leuwikopo IPB Dramaga, Bogor pada bulan Februari - Juni 2013. Percobaan menggunakan rancangan petak terbagi (Split Plot Design) dengan perlakuan terdiri dari dua faktor, yaitu sistem tanam alur sebagai petak utama dan jenis pupuk sebagai anak petak. Hasil penelitian menunjukkan bahwa perlakuan sistem tanam alur meningkatkan daya hasil pada produktivitas biji kering, produktivitas polong kering, dan bobot kering biji per tanaman lebih baik dibandingkan sistem tanam konvensional. Hal tersebut ditunjukkan dengan perlakuan sistem tanam alur yang memiliki produktivitas 2.93 ton/ha polong kering, sedangkan sistem tanam konvensional sebesar 2.55 ton/ha polong kering. Sistem budidaya kacang tanah pada sistem tanam alur dapat meningkatkan efisiensi tanaman dalam memanfaatkan unsur hara yang telah diberikan baik pupuk organik maupun anorganik, sehingga pertumbuhan dan hasil tanaman kacang tanah menjadi lebih baik. Pemberian jenis pupuk kandang ayam + Dolomit + NPK memberikan respon terhadap pertumbuhan dan  daya hasil rata-rata tanaman yang lebih baik dibandingkan jenis pupuk lainnya.</em></p>
