| Judul Artikel | Pengaruh Dosis dan Waktu Pemberian Pupuk NZEO-SR Plus Terhadap Karakteristik Fisiologi dan Hasil Tanaman Jagung Kristal |
| Abstrak (Bhs. Indonesia) | Pupuk slow release adalah pupuk yang tersedia lambat dan secara perlahan dapat menyediakan hara untuk memenuhi kebutuhan tanaman. Pupuk NZEO-SR yang dikembangkan menjadi NZEO-SR Plus yaitu dengan diperkaya Si yang berasal dari sekam padi dan modifikasi teknologi coating nano-zeolite dan bahan humat. Tujuan dari dilaksanakannya penelitian adalah untuk mengetahui pengaruh dosis dan waktu pemberian pupuk NZEO-SR Plus terhadap karakteristik fisiologis dan hasil tanaman jagung kristal, memperoleh dosis dan waktu pemberian terbaik pupuk NZEO-SR Plus terhadap karakteristik fisiologis dan hasil tanaman jagung kristal, dan mengetahui pengaruh interaksi aplikasi dosis dan waktu pemberian pupuk NZEO-SR Plus terhadap karakteristik fisiologis dan hasil tanaman jagung kristal. Penelitian dilaksanakan dari bulan November 2021 sampai dengan Maret 2022 di lahan Experimental Farm Fakultas Pertanian Universitas Jenderal Soedirman. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok Lengkap. Data dianalisis dengan uji F, apabila hasilnya beda nyata dilakukan uji lanjut Duncan’s Multiple Range Test (DMRT) pada taraf α = 5%. Variabel yang diamati adalah kehijauan daun, klorofil a dan b, kandungan prolin, diameter tongkol berkelobot, panjang tongkol dengan kelobot dan tanpa kelobot, jumlah baris biji per tongkol, bobot 1000 biji, bobot biji kering per hektar. Hasil penelitian menunjukkan bahwa dosis pupuk NZEO-SR Plus 750 kg/ha (setara 150 kg N/ha) memberikan hasil yang optimal pada kehijauan daun, diameter tongkol berkelobot, bobot 1000 biji, dan bobot biji kering per hektar. Waktu pemberian 2 kali pada saat tanaman umur 5 hari setelah tanam (50%) dan umur 30 hari (50%) menunjukkan hasil lebih baik terhadap kehijauan daun dibandingkan waktu pemberian 1 kali (100%) pada saat tanaman umur 5 hari. |
| Abtrak (Bhs. Inggris) | Slow release fertilizer is a fertilizer that is available slowly and can slowly provide nutrients to meet plant needs. The NZEO-SR fertilizer which was developed into NZEOSR Plus is enriched with Si derived from rice husks and modified nano-zeolite coating technology and humic materials. The purpose of the research was to determine the effect of the dose and timing of NZEO-SR Plus fertilizer on the physiological characteristics and yield of crystal corn plants, obtain the best dose and timing of NZEO-SR Plus fertilizer application on the physiological characteristics and yields of crystal corn plants, and determine the effect of the interaction. application of dose and timing of NZEO-SR Plus fertilizer on physiological characteristics and yield of crystal corn. The research was carried out from November 2021 to March 2022 on the Experimental Farm, Faculty of Agriculture, Jenderal Sudirman University. The experimental design used was Completely Randomized Block Design. The data were analyzed by the F test, if the results were significantly different, the Duncan's Multiple Range Test (DMRT) further test was carried out at the level of = 5%. Variables observed were leaf greenness, chlorophyll a and b, proline content, diameter of cob cob, length of cob with and without grain, number of rows of seeds per ear, weight of 1000 seeds, weight of dry seeds per hectare. The results showed that the NZEO-SR Plus fertilizer dose of 750 kg/ha (equivalent to 150 kg N/ha) gave optimal results on leaf greenness, cob diameter, 1000 seed weight, and dry seed weight per hectare. The time of giving 2 times when the plants were 5 days after planting (50%) and the age of 30 days (50%) showed better results on greenery of the leaves than the time of giving 1 time (100%) when the plants were 5 days old. |
