Pemberian unsur hara dengan pemupukan tanah seringkali kurang efisien
karena terikat oleh mineral tanah atau terbawa aliran air. Penelitian ini bertujuan
menganalisis efektifitas pemberian unsur hara menggunakan sistem infus dengan kadar
unsur hara yang berbeda berdasarkan respon pertumbuhan dan parameter fisiologis
tanaman. Percobaan dilakukan menggunakan Rancangan Acak Lengkap (RAL) 2
faktor dengan 3 ulangan. Faktor pertama adalah jenis tanaman yaitu tomat dan cabai
rawit, faktor kedua adalah konsentrasi nutrisi (larutan Hoagland) yang terdiri dari 5
taraf yaitu: infus larutan Hoagland full strength (P1), infus half strength (P2),
pemupukan pada media tanam menggunakan larutan Hoagland full strength (P3) dan
half strength (P4), air murni (kontrol negatif) (P5). Data pengamatan dianalisis
menggunakan ANOVA dilanjutkan Uji Duncan dengan nilai 5%. Hasil penelitian
menunjukkan aplikasi larutan Hoagland dengan infus cukup efektif dalam
menyediakan unsur hara bagi tanaman, walaupun belum tentu dapat menggantikan
kebutuhan unsur hara seluruhnya. Parameter pertumbuhan seperti luas daun, berat
kering, panjang akar dan diameter pembuluh kayu dipengaruhi perlakuan infus,
sementara parameter lain seperti tinggi tanaman, jumlah daun, dan kandungan klorofil
memiliki hasil yang kurang efektif. Hasil penelitian juga menunjukkan bahwa tanaman
dengan perlakuan infus tidak mengalami kerusakan pada xilem batang, yang berarti
aplikasi infus dengan jarum no: 25G dapat diterapkan untuk mengantarkan zat hara ke
tanaman, walaupun mungkin diperlukan beberapa penyesuaian untuk memastikan
tanaman tidak mengalami stres. Providing nutrients by fertilizing the soil is often less efficient, because it
is bound by soil minerals or washed away by running water. This study aimed to
analyze the effectiveness of nutrient supply using an infusion system with
different nutrient levels based on the growth response and physiological
parameters of plants. The experiment was using 2-factor Completely Randomized
Design (CRD) with 3 replications. The first factor was the type of plant, namely
tomatoes and cayenne pepper, the second factor was nutrient concentration
(Hoagland's solution) which consisted of 5 levels, i.e.: full strength infusion of
Hoagland solution (P1), half strength infusion (P2), as well as direct fertilization
in the media using Hoagland's full strength (P3) and half strength solution (P4),
pure water (as negative control) (P5). Observational data were analyzed using
ANOVA followed by Duncan Test with 5% of value. The results showed that
the application of Hoagland's solution by infusion was quite effective in providing
nutrients for plants, although it may not be able to replace the entirely nutrients
need. Meanwhile, it affected several plant growth parameters such as leaf area,
dry weight, root length and xylem vessel diameter while other parameters such as
plant height, number of leaves, and chlorophyll content were less effective. The
results also showed that the plants that were applied the infusion treatment did not
experience any damage in the stem xylem, suggesting that infuse application with
needle no: 25G would be applicable to deliver substance to the plant, even though
some adjustment may be required to ensure that the plants are not experiencing
stress.
