Abstract

FARIZ ZULFIKAR HANIF. Pengaruh Peredaan Frekuensi Penyiraman Terhadap Produktivitas Green fodder Jagung dan Sorgum (The Effect of Differences in Watering Frequency on the Productivity of Maize and Sorghum Green fodder). Dibimbing oleh TERA FIT RAYANI, S.Pt, M.Si Keterbatasan lahan hijauan pakan ternak penggunaan teknologi hidroponik sebagai solusi penyediaan pakan yang efisien, salah satunya dalam bentuk green fodder. Penelitian ini bertujuan untuk mengevaluasi pengaruh frekuensi penyiraman terhadap produktivitas green fodder dari benih jagung dan sorgum. Penelitian dilaksanakan selama 15 hari di Bio Composting Sekolah Vokasi IPB University, menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan dua faktor, frekuensi penyiraman (3 jam dan 6 jam) dan jenis benih berbeda (jagung dan sorgum), masing-masing faktor diulang dengan empat ulangan. Peubah yang diamati meliputi aspek tinggi tanaman, jumlah helai daun, bobot biomassa segar, konversi benih terhadap biomassa, persentase tajuk dan akar, serta rasio tajuk terhadap akar. Hasil penelitian menunjukkan bahwa benih jagung memiliki produktivitas lebih tinggi dibandingkan benih sorgum, baik dari sisi pertumbuhan maupun konversi biomassa. Frekuensi penyiraman 6 jam menghasilkan tinggi tanaman yang lebih baik dibandingkan dengan 3 jam, namun tidak berpengaruh nyata terhadap biomassa segar. Kombinasi benih jagung dan frekuensi penyiraman 6 jam memberikan hasil terbaik dalam aspek pertumbuhan dan produktivitas green fodder.

FARIZ ZULFIKAR HANIF. The Effect of Differences in Watering Frequency on the Productivity of Maize and Sorghum Green Fodder. Supervised by TERA FIT RAYANI, S.Pt, M.Si The limitation of forage land for livestock feed has encouraged the utilisation of hydroponic technology as an efficient solution for feed production, one of which is in the form of green fodder . This study aimed to evaluate the effect of irrigation frequency on the productivity of green fodder derived from maize and sorghum seeds. The research was conducted over a period of 15 days at the Bio Composting Facility, Vocational School, IPB University, using a factorial Completely Randomised Design (CRD) with two factors: irrigation frequency (3 hours and 6 hours) and seed type (maize and sorghum), each replicated four times. Observed variables included plant height, number of leaves, fresh biomass weight, seed-to-biomass conversion, shoot and root percentage, as well as shoot-to-root ratio. The results demonstrated that maize seeds produced higher productivity than sorghum seeds, in terms of both growth and biomass conversion. Irrigation every 6 hours resulted in better plant height compared to 3 hours, although the difference was not statistically significant for fresh biomass. The combination of maize seeds and 6-hour irrigation frequency yielded the best performance in terms of green fodder growth and productivity.
