Abstract

Sorghum (Sorghum bicolor L. Moench) is one of the cereal plants that can be used as animal feed. “Miting Tadda” sorghum variety has the potential to be cultivated in Central Java, precisely in Getasan Sub-district. Currently, the optimal macronutrient recommendations including nitrogen (N), phosphorus (P), and potassium (K) for sorghum cultivation in Central Java are not yet known. The fertilizer dosage for sorghum plants that has been found in the literature is not specific to the Miting Tadda sorghum type and the type of soil in Getasan. This study aimed to determine the effect of various fertilizer doses on the productivity and quality of seeds and greens of Miting Tadda sorghum variety. The study was conducted at the Science Techno Park, Faculty of Agriculture and Business, Satya Wacana Christian University. This study used a Randomized Block Design (RBD) with 5 fertilizer dose treatments (g per plant), namely: without fertilizer, 2.44 N + 0.5 P₂O₅ + 0.45 K₂O, 3.69 N + 0.5 P₂O₅ + 0.45 K₂O, 4.89 N + 0.5 P₂O₅ + 0.45 K₂O, 6.08 N + 0.5 P₂O₅ + 0.45 K₂O. The experiment was conducted in 4 groups as replications so that there were 20 experimental units. The results showed that based on the results of the ANOVA test, there was no significant effect of the NPK fertilizer dose treatment in the range given in this study on the components of sorghum seed and forage productivity and the quality of sorghum seeds and forage was relatively the same in all treatments. The use of fertilizers in low doses or even without fertilizer can be an alternative in sorghum cultivation.

Abstract

Pendahuluan: Tujuan penelitian ini adalah mengetahui pengaruh dosis pupuk NPK yang berbeda terhadap pertumbuhan dan hasil panen sorgum lokal Sumba Timur Watar Hammu Manippa Tadda. Metode Penelitian: Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian dan Bisnis Universitas Kristen Satya Wacana menggunakan Rancangan Acak Kelompok (RAK) Perlakuan disusun pada 4 blok (kelompok). Setiap blok berukuran 3,5 x 2,25 m dengan jarak tanam 50x50 cm sehingga diperoleh 20 satuan percobaan dengan tanaman per blok/kelompok adalah 35 tanaman. Data pertumbuhan diambil setiap 1 minggu sekali. Data produktivitas diambil setelah tanaman memasuki masa panen dan kadar air biji mencapai 15-20%. Data pertumbuhan dianalisis menggunakan metode statistik deskriptif (rerata dan standar deviasi). Data hasil panen (produktivitas) dianalisis menggunakan metode analisis of variance (ANOVA)/analisis sidik ragam dengan tingkat kepercayaan 95%, Jika terdapat pengaruh maka dilanjutkan dengan uji BNT dengan tingkat kepercayaan 0,05. Hasil Penelitian: Tadda. Hasil percobaan menunjukan perlakuan pupuk NPK menunjukkan pertumbuhan yang optimal dengan perkembangan morfologi yang baik dan adaptif pada komponen pertumbuhan. Komponen hasil menunjukan perlakuan pupuk NPK perlakuan dosis pupuk N tidak berpengaruh nyata terhadap panjang malai sampel, bobot biji sampel dan ubinan, Bobot kering malai sampel dan ubinan, Bobot kering daun tanaman sampel, bobot kering batang ubinan, Bobot kering akar sampel, usia panen sampel dan ubinan, indeks panen biji sampel, dan estimasi produksi biji ubinan namun berpengaruh nyata pada bobot kering batang sampel, bobot kering daun ubinan, dan Indeks panen biji ubinan.
