      Abstract
      Hasil produksi kacang tanah dapat ditingkatkan dengan cara melakukan pemangkasan pada cabang tanaman. Pemangkasan pada cabang diharapkan dapat menekan laju pertumbuhan vegetatif sehingga laju pertumbuhan generatif meningkat. Penelitian ini bertujuan mengetahui jenis pangkas dan waktu pangkas yang berpengaruh terhadap hasil produksi kacang tanah. Penelitian ini dilaksanakan di Kebun Percobaan Leuwikopo IPB pada bulan November 2020 sampai Maret 2021. Rancangan percobaan yang digunakan dalam penelitian ini adalah rancangan petak terbagi (split-plot) dengan petak utama merupakan jenis pangkas dan anak petak merupakan waktu pangkas. Jenis pangkas yang digunakan adalah tanpa pangkas, pangkas batang utama, dan pangkas cabang lateral. Waktu pangkas adalah pada saat tanaman berumur 6 MST, 8 MST, dan 10 MST. Hasil penelitian menunjukkan jenis pangkas berpengaruh nyata terhadap jumlah cabang lateral pada 8 MST, 10 MST, dan 12 MST. Jenis pangkas juga berpengaruh nyata terhadap bobot 100 biji. Waktu pangkas tidak memberikan pengaruh yang nyata terhadap peubah pengamatan yang diamati. Interaksi antar kedua perlakuan berpengaruh nyata terhadap bobot 100 biji.
       
      Peanuts production can be increased by pruning plant branches. Pruning is expected can be suppressed the vegetative growth rate so that the generative growth rate increases. The purpose of this research is to find out which type and time pruning that can affect peanuts production. This research was conducted in Leuwikopo Experimental Station IPB on November 2020 until March 2021. This research is arranged in split-plot randomized block design with the main plot is the type of pruning and the subplot is time of pruning. The types of pruning are without pruning, main branches pruning, and lateral branches pruning. Time of pruning is when the age of the plant are 6 weeks after planting, 8 weeks after planting, and 10 weeks after planting. The result shows that type of pruning affects the number of lateral branches at week 8, week 10, and week 12. Type of pruning also affects weight of 100 seeds. Time of pruning does not have significant effect on the observed variables. Interaction between the two treatments affect the weight of 100 seeds.
