Growth and productivity of cassava given organic fertilizer and potential waste as a source of animal feed

Abstract

The research was conducted to determine the growth and productivity of cassava plants that are given organic fertilizers and their potential waste as ruminant animal feed. The research was conducted at Kerthi Winangun Farmers Group, Bukti village, Kubutambahan District, Buleleng Regency. The experiment was arranged in a completely randomized design with three fertilization treatments and twelve replications. The fertilizer given were: cow dung 5 kg/plant (UK1), compost 5 kg/plant (UK2) and cow dung 5 kg/plant + bio urine 300 ml/plant (UK3). The Parameters observed were (1) plant growth (height, Number of leaves and tubers), (2) tuber production, (3) waste (leaf and peel) production and (4) carrying capacity. The result shows that application of 5 kg compost/plant yielded the highest tuber, leaf and peel production was respectively 1789,25±475,50, 667 ± 104 and 416,61±18 g/plant. Production of this peel can be used to feed 1.29-1.52 cattle/ha/year or 10.73-12,68 goat/ha/year. In conclusion, the cassava that was given with 5 kg compost per plant has the highest production to be used as a source of feed for ruminants.

PERTUMBUHAN DAN PRODUKSI DUA KLON UBIKAYU (Manihot esculenta Crantz) AKIBAT APLIKASI PUPUK KANDANG SAPI

“…Perbandingan antara pemberian pupuk kandang sapi dan kompos pada dosis yang sama yaitu 5 kg/tanaman, bobot segar ubi per tanaman lebih rendah (1,100 g/tanaman) pada pemberian pupuk kandang sapi disbanding dengan kompos (1,800 g/tanaman). Informasi ini membuktikan bahwa pemberian pupuk kandang sapi kurang dari 10 ton/ha masih belum mampu meningkatkan produksi ubikayu (Dinata et al, 2021).…”
