Abstract

This study aims to determine the effect of NPK dosage, types of complementary fertilizers and their interactions on the growth and production of chilies pepper.  This research was conducted in Sukabanjar Village, Gedong Tataan, Pesawaran Regency from July-December 2020.  The experimental design used in this study was a two-factor randomized block design (RBD), namely the dose of NPK fertilizer and the type of complementary fertilizer (4 × 2) with 3 replications.  Each plot consisted of 8 plants so that there were 192 plants.  The first factor was NPK Mutiara fertilizer dose (16:16:16)(N) with N0:0 g/plant, N1:10 g/plant, N2:20 g/plant and N3:30 g/plant.  The second factor is the type of complementary fertilizer (P) with P1 Plant Catalyst and P2 Gandasil D. Homogeneity of variance was tested by Bartlett test, additivity was tested by Tukey test. Then it was continued with analysist of variance and with the Least Significant Difference test (LSD) at the 5% level. Treatment of NPK fertilizer dosage significantly increases growth and yield.  The interaction between the NPK dosage of 20g/plant and type of complementary fertilizers gave highest plant height (95.58 cm). The best  combination was NPK dosage of 20 g/plant and Plant Catalyst fertilizer that gave highest yield (753,17 g/plant equivalent 15.06 ton/ha at population 20,000 plant/ha.Keywords : Chili pepper, complimentary fertilizer, growth, NPK, yield

Abstract

Ornamental plants have now developed as souvenirs given at a wedding. Requirements for souvenirs, the plants should be tiny, lush, and have much of flowers. So its growth needs to be modified using a growth regulator paclobutrazol. This study aimed to determine the response of angelonia plants to the application of paclobutrazol at several levels of concentration and determine the concentration of paclobutrazol which has the best appearance of angelonia plants. This research method used a randomized block design (RBD) with treatment of 6 levels of paclobutrazol concentration, namely 0 ppm, 30 ppm, 60 ppm, 90 ppm, 120 ppm and 150 ppm with 3 replications. The F test and further tests were carried out an Orthogonal Polynomials. All tests were carried out at the 5% level. The results showed that the application of paclobutrazol at a concentration level of 30-150 ppm, was effective in suppressing the growth rate of angelonia plants in the vegetative phase. This value was proved by the results of the questionnaire that, the highest visual value was obtained at a concentration of 150 ppm. But with the increasing concentration of paclobutrazol, the freshness of  flowers became shorter. Keywords: Angelonia, Concentration, Paclobutrazol

Abstract

Gisting merupakan representasi wilayah pertanian frontier, antara pedesaan padat penduduk dan gunung berupa hutan lindung, yang merupakan sentra produksi sayur, ternak, kopi, dan pariwisata. Kegiatan pengabdian kepada masyarakat ini yang dilaksanakan di Desa Sidokaton, Kecamatan Gisting, Kabupaten Tanggamus bertujuan untuk meningkatkan pengetahuan dan keterampilan anggota kelompok tani Tanggamus Handayani dalam memahami pengembangan pertanian frontier dan agroforestry untuk peningkatkan produktivitas lahan dan pengembangan agrowisata menuju desa wisata. Kegiatan ini dilaksanakan dengan metode ceramah dan tatap muka, Focus Group Discussion (FGD), pendampingan penguatan kelompok, serta anjangsana dan anjangkarya. Kegiatan ini melibatkan mahasiswa anggota PERMA AGT Fakultas Pertanian Universitas Lampung. Pengabdian ini dapat berjalan lancer dengan skore partisipasi 10 (skor 0-15) dan dapat meningkatkan pengetahuan dan keterampilan petani dalam pengembangan sistem usahatani pertanian dan agroforestry di wilayah frontier desa dan hutan lindung pegunungan serta pengembangan agrowisata dengan skore 38 (dari 0-50) yang berkategori baik.
