      Abstract
      Kacang tanah merupakan tanaman Leguminosae yang sudah banyak dikenal dan dibudidayakan di Indonesia. Namun, produksi kacang tanah di Indonesia masih rendah dan cenderung stagnan. Hal ini disebabkan oleh tidak tersedianya lahan yang cukup luas untuk memproduksi kacang tanah serta teknik budidaya yang masih tergolong tradisional. Tujuan penelitian ini adalah untuk mempelajari pengaruh penggunaan beberapa jenis pupuk dan pemangkasan terhadap daya hasil tanaman kacang tanah varietas Pelanduk. Penelitian ini dilaksanakan di Kebun Percobaan Institut Pertanian Bogor, Desa Cikarawang, Kabupaten Bogor dari bulan Maret sampai Juni 2020. Penelitian ini menggunakan kacang tanah varietas Pelanduk dengan rancangan petak terbagi (split plot) dua faktor perlakuan. Petak utama adalah perlakuan pemberian beberapa jenis pupuk yang terdiri dari 5 taraf yaitu, tanpa pupuk, NPK Mutiara 300 kg ha-1, NPK Mutiara 300 kg ha-1 + kapur Dolomit 1 ton ha-1, pupuk kandang 1 ton ha-1 + pupuk daun 2 ml l-1, dan pupuk kandang 1 ton ha-1 + pupuk daun 2 ml l-1 + kapur Dolomit 1 ton ha-1. Pemangkasan sebagai anak petak terdiri dari 3 taraf yaitu, tanpa pangkas, pemangkasan 1 cabang lateral, dan pangkas batang utama. Perlakuan jenis pupuk memberikan pengaruh yang nyata pada hasil kacang tanah yaitu peubah bobot basah ubinan, bobot kering ubinan, dan produktivitas polong tanaman kacang tanah. Sedangkan pada perlakuan pemangkasan dan interaksi antara keduanya tidak memberikan hasil yang berpengaruh secara nyata. Hasil penelitian menunjukkan bahwa pemberian pupuk NPK Mutiara 300 kg ha-1 + kapur Dolomit 1 ton ha-1 memberikan hasil yang lebih tinggi pada peubah komponen hasil, namun tidak berbeda nyata dari pupuk NPK Mutiara 300 kg ha-1.
       
      Peanut is a Leguminoceae plant that is widely known and cultivated in indonesia. However, peanut production in Indonesia is still low and tends to be stagnant. This is caused by the unavailability of large enough land to produce peanuts and cultivation techniques that are still classified as traditional. The purpose of this research was to study the effect of using several types of fertilizers and pruning on the yield of Pelanduk peanut variety. This research was conducted at the Experimental field of the Bogor Agricultural University, Cikarawang Village, Bogor Regency from March to July 2020. This research used peanut varieties Pelanduk with split plot design of two treatment factors. The main plot is the treatment of giving several types of fertilizers consisting of 5 levels, namely, without fertilizer, NPK Mutiara 300 kg ha-1 , NPK Mutiara 300 kg ha-1 + Dolomite lime 1 ton ha-1 , manure 1 ton ha-1 + leaf fertilizer 2 ml l-1 , and manure 1 ton ha-1 + leaf fertilizer 2 ml l-1 + Dolomite lime 1 ton ha-1 . Pruning as a subplot consists of 3 levels, namely, without pruning, pruning 1 lateral branch, and pruning the main stem. Treatment of the type of fertilizer had a significant effect on the yield of peanuts, namely the variables of the wet weight of the tuberose, the dry weight of the tuberose, and the productivity of peanut pods. Meanwhile, the pruning treatment and the interaction between the two did not give any significant effect. The results showed that the application of NPK Mutiara fertilizer 300 kg ha-1 + Dolomite lime 1 ton ha-1 gave higher yields on the yield component variables, but was not significantly different from NPK Mutiara fertilizer 300 kg ha-1 .
