Pengembangan tanaman jarak pagar mengalami beberapa kendala, di antaranya produksi biji yang rendah. Hal ini terkait dengan rendahnya jumlah bunga betina yang dihasilkan dalam satu malai. Penelitian yang bertujuan untuk mengetahui pengaruh pemberian zat pengatur tumbuh (ZPT) terhadap pertumbuhan, pem-bungaan, dan produksi jarak pagar, dilakukan di KP Asembagus pada bulan Januari−Desember 2010. Lima jenis bahan aktif ZPT meliputi paclobutrazol, asam geberelin (GA3), asam naptalin asetik (NAA), mepiquat klorida, dan 2,4-D, serta perlakuan kontrol (tanpa bahan aktif ZPT), diaplikasikan pada tanaman jarak pagar berumur 1 tahun dan disusun dalam rancangan acak kelompok dengan tiga ulangan. Hasil penelitian me-nunjukkan bahwa aplikasi ZPT mempengaruhi jumlah cabang, jumlah bunga jantan, jumlah bunga betina, dan jumlah buah, namun tidak mempengaruhi tinggi tanaman dan lebar kanopi. NAA menghasilkan jumlah buah yang paling banyak (121,4 buah per tanaman) sedangkan GA3 mempercepat pemunculan bunga (8,33 hari setelah aplikasi). Development of physic nut is facing some problems, one of them is low seed production. This is related to the low number of female flowers which are produced in a panicle. The aim of the study is to determine the effect of plant growth regulator (PGR) on growth, flowering, and seed production, it was conducted at Asembagus Experimental Station, Situbondo from January to December 2010. Five kinds of plant growth re-gulator i.e. paclobutrazol, geberelline acid (GA3), naphthalene acetic acid (NAA), mepiquat chloride, and 2,4-D, and control (without PGR) were applied on one-year-old of J. curcas and arranged in a randomized block de-sign with three replications.
