Abstract: | Pemupukan merupakan upaya peningkatan status kesuburan tanah untuk
meningkatkan pertumbuhan dan hasil tanaman pada tingkat yang optimum.
Penelitian ini bertujuan mengevaluasi efektivitas pupuk cair yang dikombinasikan
dengan 0,5 atau 0,75 dosis pupuk N, P, dan K yang dibandingkan dengan dosis
pupuk NPK standar terhadap pertumbuhan dan hasil jagung manis. Percobaan
lapang dilakukan dengan menerapkan RAK yang terdiri dari 6 taraf perlakuan
aplikasi pupuk cair (PC) dan pupuk NPK standar (NPK), yaitu kontrol, NPK, 2 PC,
PC + 0,75 NPK, 2 PC + 0,5 NPK, dan 2 PC + 0,75 NPK, masing-masing dengan 3
ulangan. Analisis data hasil percobaan meliputi Analysis of Variance (ANOVA),
uji lanjut Duncan Multiple Range Test (DMRT), dan Relative Agronomic
Effectiveness test (RAE). Hasil penelitian menunjukkan bahwa perlakuan
berpengaruh nyata terhadap tinggi tanaman, jumlah daun, dan berat tongkol jagung.
Aplikasi pupuk cair dengan kombinasi 0,5 dan 0,75 NPK berpengaruh nyata
terhadap jumlah daun, tinggi tanaman dan hasil panen jagung manis, tetapi
pengaruh perlakuan pupuk cair tunggal tidak berbeda nyata dengan kontrol.
Perlakuan 2 PC + 0,75 NPK menunjukkan pengaruh yang sama dengan NPK
standar terhadap parameter pertumbuhan dan hasil jagung manis, sedangkan
perlakuan lainnya lebih rendah dari NPK standar. Fertilizer is an effort to improve soil fertility status as to increase the growth and yield of the crop at an optimum level. This study was aimed to evaluate the effectiveness of application of liquid combined with 0.5 or 0.75 doses of N, P, and K fertilizer compared standard NPK fertilizers on the growth and yield of sweet corn. This field experiment was arranged in randomized completely block design (RCBD) with six application levels of liquid fertilizer (LF) and standard NPK fertilizer (NPK), namely control (no fertilizer), NPK, 2LF, LF + 0.75NPK, 2LF + 0.5NPK, and 2LF + 0.75NPK, each with three replications. The experimental data were subjected to analysis of variance (ANOVA), Duncan Multiple Range Test (DMRT), and Relative Agronomic Effectiveness (RAE) test. The results showed that the treatment significantly affected the plant height, leaf number, and cobs’ weight of sweet corn. Application of LF combined with 0,5 or 0,75 of NPK significantly affected leaf number, plant height, and yield of sweet corn, but the effects of single application of LF was not significantly different with control. The treatment of 2LF+0.75NPK showed comparable effects with NPK on the growth parameters and yield of sweet corn, while those of the other treatments were lower than of the NPK treatment. |
