Abstract

Porang is a tuber plant that has the opportunity to be developed in Indonesia. Efforts have been made to increase the production potential of porang, including through nurseries. The purpose of this study was to determine the effect of tuber origin and concentration of gibberellin growth regulators on porang growth. The research was conducted in Wonosobo Village, Srono District, Banyuwangi Regency from August to November 2020. This study used a Randomized Block Design (RBD) with two factors, namely the origin of the seeds and the concentration of gibberellin growth regulators with three replications. Factors of seed origin consisted of tubers (B1) and air bulbs (B2) while ZPT gibberellin concentration factors were 1 ml/l (A1), 2 ml/l (A2), 3 ml/l (A3), 4 ml/l ( A4) and 5 ml/l (A5), resulting in 10 treatment combinations. Observational variables include shoot height and number of leaves. On the seedling origin factor, the B2 treatment was the highest in terms of the observed parameters of shoot height and number of leaves. In the ZPT gibberellin concentration factor, it was shown that factor A1 was the highest in the observed variable of shoot height 20 dap (days after planting), while in the variable number of leaves 50 dap, factors A4 and A5 had the highest number of leaves. The interaction of seed origin and gibberellin concentrations showed that factor B1A4 had the highest shoot height at 20 dap observations, while B1A5 had the highest number of leaves at 40 and 50 dap observations.

Abstract

Pemangkasan pucuk daun mendorong pertumbuhan tunas lateral, dengan tumbuhnya tunas lateral akan menambah percabangan pada tanaman kacang hijau (Vigna radiata L.) yang meningkatkan jumlah bunga dan bakal polong per tanaman. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemangkasan pucuk daun terhadap hasil produksi tanaman kacang hijau (Vigna radiata L.). Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan satu faktor dan tujuh ulangan. Perlakuan pemangkasan pucuk daun tanaman umur 15 hari setelah tanam (P3) menunjukkan hasil presentase berbeda sangat nyata terhadap parameter pengamatan jumlah polong, jumlah biji dan berat total biji. Perlakuan pemangkasan 15 hst (P3) memiliki jumlah polong dengan rerata 26,89 buah, jumlah biji dengan rerata 191,41 biji, berat total biji dengan rerata 11,60 g. Perlakuan pemangkasan pucuk 15 hst (P3) memiliki hasil presentase berbeda nyata terhadap parameter pengamatan berat kering polong dengan rerata 15,45 g.
