Pemanfaatan Berbagai Level Tepung Tulang Terhadap Jumlah Daun, Tinggi Batang Dan Jumlah Akar Hidroponik Fodder Jagung
This research was conducted at the Field Laboratory of the Faculty of Animal Husbandry,
Universitas PGRI Kanjuruhan Malang on April 13 – June 15 2022, with the aim of
examining the utilization of various levels of bone meal on the number of leaves, stem
height and the number of hydroponic roots of fodder cornThe research material used was
2000 grams of corn. The method used is a field experiment using a completely
randomized design (CRD). The research treatment consisted of 4 treatments, including
P0: 0%, P1 5%, P2: 10%, P3 15% with bone meal as a treatment. The variables used were
the number of leaves, the number of roots and the height of the stem. if there is a
difference between the treatments, then proceed with the Least Significant Difference
test. Based on the results of the study showed that various levels of bone meal as a
treatment showed that there was a very significant effect (P < 0.01) on the number of
leaves, several roots, and height of hydroponic corn fodder stems for 14 days, namely as
follows: Number of leaves, without using flour bone meal 0% 2.11±0.16, bone meal 5%
2.76±0.15, bone meal 10% 3.74±0.49, bone meal 15% 2.50±0.28. Total roots, without
adding 0% bone meal 3.88±0.55, 5% bone meal 4.06±2.19, 10% bone meal 5.44±0.77,
15% bone meal 3.68±0 ,28. Stem height, without adding 0% bone meal 8.64±0.43, 5%
bone meal 8.85±0.31, 10% bone meal 13.12±0.90, 15% bone meal 8.34±0 ,21. The
highest value for each variable can be in P2, namely: number of leaves 3.74, number of
roots 5.44, stem height 13.12, for 14 days.Based on the results of this study, it was shown
that spraying the corn fodder hydroponic system with a bone meal for 14 days and the
highest average value with a concentration of 10% bone meal + 90% water was the
best.Suggestion: In spraying the corn fodder hydroponic system with bone meal solution,
it is better to pay attention to the use of bone flour solution concentration because it can
affect good results.
