Abstract

Penelitian ini bertujuan untuk mendapatkan konsentrasi pupuk organik cair yang lebih baik untuk pertumbuhan dan hasil tanaman jagung ungu. Penelitian dilaksanakan di Jalan Padat Karya, Tondo, Kecamatan Mantikulore, Kota Palu Sulawesi Tengah. Penelitian dilaksanakan dari bulan April sampai Juni 2022. Penelitian menggunakan Rancangan Acak Kelompok dengan satu faktor perlakuan yaitu pupuk organik cair dengan 5 taraf perlakuan yaitu tanpa POC (kontrol), 4 ml POC/liter air, 6 ml POC/liter air, 8 ml POC/ liter air, 10 ml POC/liter air. Setiap perlakuan diulang sebanyak 5 kali sehingga diperoleh 25 satuan percobaan. Jarak tanam yang digunakan 80cm x 50cm dengan luas petak 300 cm X 320 cm. Hasil penelitian menunjukkan bahwa perlakuan dengan dosis 10 ml/l air memberikan pengaruh lebih baik terhadap pertumbuhan dan hasil tanaman jagung ungu yaitu pada semua parameter yaitu, tinggi tamanan, jumlah daun, jumlah tongkol perumpun, diameter tongkol, berat tongkol tanpa kelobot , berat tongkol berkelobot, produksi per petak dan produksi ton/ha.

Abstract

atchouli (Pogostemon cablin Benth.) is an aromatic plant, well known to produce valuable essential oils. Patchouli productivity in Indonesia from 2014 to 2020 was quite fluctuated. Plant growth and productivity is influenced by climate factors and water availability. Drought for instance can disrupt photosynthetic cycle and lowering the biomass production. Patchouli plants have shallow roots, susceptible more to drought stress. This experiment was conducted to identify the effect of watering field capactiy status on growth and biomass production of Patchouli. The experiment was carried out at the Greenhouse for Research and Assessment of Agricultural Technology (IP2TP) Sidondo, Sidondo III Village, Sigi Biromaru District, Sigi Regency, Central Sulawesi, from January to March 2022. This study used Randomized Block Design (RAK) which consisted of one factor, namely diferent water levels expressed in percentage of water field capacity (KL). There were 6 differents KL treatment K0 = 100%, K1 = 90%, K2 = 80%, K3 = 70%, K4 = 60%, K5 = 50%. Each treatment was repeated 4 times with 3 plants, in total there were 72 experimental units (polybags). The results showed that 90% and 100% of water field capacity (KL) increase the growth and impact to higher patchouli biomass, 46.35 g and 47.93 g, respectively. When KL is dropped to 80%, the biomass is reduced 20%. It is therefor, to maintain higher biomass production, the water field capacity shall be kept at least 90%.
