Produksi Rumput Gajah (Pennisetum purpureum) yang Diberi Pupuk N, P dan K dengan Dosis 0, 50 dan 100% pada Devoliasi Hari ke-45
Abstrak: Production of
elephant grass (Pennisetum purpureum) would be better if fertilized with the
proper doses and appropriate. This study aimed to determine the production of
fresh matter, dry matter, ratio of grass stems and leaves, dry matter and
organic matter of elephant grass given fertilizer N, P and K with the doses of
0%, 50% and 100% at defoliation at 45th day. This study used an experimental
method of randomized block design experiment consisted of 5 and 3 treatments groups,
so there were 15 experimental units. The treatments used were: Treatment 1
(control/not fertilizer), Treatment 2 (100 kg Urea/ha; 50 kg TSP/ha; 50 kg
KCl/ha) and Treatment 3 (200 kg Urea/ha, 100 kg TSP/ha: 100 kg KCl/ha). The
results showed that the doses of fertilization treatments did not significantly
(P≥ 0,05) affect the fresh matter, dry matter, ratio of grass stems:leaves, dry
matter and organic matter value of elephant grass at the first harvest aged
45th day. Treatment 2 and 3 increased forage the fresh matter production by 29.86%
and 28.51%, respectively, while production of dry matter by 28.85% and 30.77%
compared to treatment 1 (control). The ratio of grass stems and leaves varied
between 59.1 - 61.26%:38,7 - 40, 9%. Organic matter content tended to increase
with increasing doses of N, P and K fertilizer.
Key words: elephant grass
production, N, P, and K fertilizer, fertilizer doses
