Abstract

Crop losses due to phytonematodes infection commonly occurred on intensive plantation practiced for a long time. The research was aimed to study phytonematodes status on several age-different plantation of Cavendish banana in PT NTF Way Kambas, Lampung. Soil and root samples were taken from three different plantations, selected based on time period of cultivation practice, i.e. 3–5, 10–12, and 17–19 years long. The modification of Baermann funnel method was applied to collect nematodes. The status of phytonematodes were determined based on the absolute frequency (AF), relative frequency (RF), and absolute population (AP) of each genus. The results showed that 13 phytonematodes genera inhabited Cavendish banana crops. Pratylenchus and Radopholus have important status on a land that had been cultivated for 3–5 and 10–12 years with AF 100%, RF 31%, and  AP 298.8, and 423.0  individues per 200 mL of soil, respectively on 3–5 years long lands, and AF100%, RF 39% and PA 215, and 126 individues per 200 mL of soil, respectively on 10–12 years long lands. Pratylenchus and Radopholus were less important on 17–19 years long rotated lands with AF 77%, RF 22% and AP 33.0 and 16.4 individues per 200 mL of soil respectively. The status of other phytonematodes were not important with low value of AF, RF, and AP.

Abstract

In general, banana stem waste is rarely processed into liquid organic fertilizer (LOF) for plants. This study aims to determine the effect of banana stem LOF concentration on the growth of sugarcane cuttings using the Bud Chip method. Five treatments of banana stem LOF concentration were tested in this study, namely 0, 150, 300, 450, and 600 ml/l. The experiment used a randomized block design with 5 replications. The data were analyzed by means of variance and continued with the comparison test of orthogonal and orthogonal polynomials at 5% significance level. The results showed that sugarcane cuttings given banana stem LOF produced better cuttings growth compared to sugarcane cuttings that were not given banana stem LOF, seen in the observation variables of shoot height, number of leaves, root length, shoot wet weight, shoot dry weight, root wet weight, and root dry weight. In the same observation variable, the concentration of banana stem LOF had a quadratic effect in which it initially increased the growth of sugarcane cuttings, until it reached the optimal concentration between 411.78 - 432.55 ml/l, then the growth of sugarcane cuttings decreased as the concentration of banana stem LOF increased.

Abstract

Lindi sampah kota memiliki kandungan unsur hara makro dan mikro essensial bagi tanaman. Namun, kandungan senyawa pada lindi belum memenuhi standar sebagai pupuk organik cair, sehingga perlu upaya pemekatan agar lebih berdayaguna. Penelitian ini bertujuan untuk mengetahui pengaruh peningkatan dosis pupuk granular berbahan dasar lindi sampah kota terhadap kandungan nitrogen pada media pembibitan lada (Piper nigrum L.). Penelitian disusun menggunakan Rancangan Acak Kelompok Lengkap (RAKL). Perlakuan terdiri dari lima taraf dosis pupuk granular lindi sampah kota yaitu: tanpa pupuk (P0); 10 gram/polibag (P1); 20 gram/polibag (P2); 30 gram/polibag (P3); dan 40 gram/polibag (P4). Penelitian dibagi lima kelompok yang sekaligus menjadi ulangan, sehingga terdiri dari 25 satuan percobaan dan setiap satuan percobaan terdiri dari lima media pembibitan tanaman lada. Untuk mengetahui pengaruh pelakuan dilakukan analisis kesamaan ragam data dengan uji Bartlett dan keaditifan data dengan uji Tukey. Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji Beda Nyata Terkecil, Perbandingan Ortogonal, dan Ortogonal Polinomial pada taraf pengujian 5%. Hasil penelitian menunjukan bahwa pupuk granular berbahan dasar Lindi sampah kota mampu meningkatkan kandungan nitrogen dalam media pembibitan tanaman lada. Dosis pupuk granular lindi sampah kota 20 g/polibag merupakan dosis terbaik dengan kandungan N 0,35%. Namun kandungan N media pembibitan lada tanpa pupuk tidak berbeda nyata dengan dosis 10, 30, dan 40 g/polibag. Peningkatan dosis pupuk granular lindi sampah kota mampu meningkatkan kandungan nitrogen mengikuti pola kuadratik, dengan persamaan y = -0,00009x2 +0,0035x +0,2828; R2= 0,3106.
