Respon Pertumbuhan dan Produktivitas Dua Varietas Kedelai Terhadap Perbedaan Konsentrasi Pupuk Organik Cair (POC)

Abstract

Penelitian bertujuan untuk menganalisis pengaruh konsentrasi Pupuk Organik Cair (POC) terhadap pertumbuhan dan produktivitas dua varietas kedelai yang berbeda. Penelitian menggunakan Rancangan Acak Kelompok Faktorial dua faktor. Faktor pertama yaitu kedelai Varietas Anjasmoro dan Lokal Desa Sirapan, sedangkan Faktor kedua merupakan variasi dari konsentrasi pupuk organik cair, diantaranya perlakuan kontrol, POC 7,5 ml/L, 10 ml/L, dan 12,5 ml/L. Peubah yang diamati meliputi daya berkecambah, tinggi tanaman, diameter batang, jumlah daun, jumlah cabang, umur berbunga, kandungan klorofil daun, jumlah polong isi, jumlah polong hampa, bobot polong, bobot biji, bobot 100 biji, bobot berangkasan, serta produktivitas kedelai. Data dianalisis menggunakan analisis ragam (ANOVA) dan uji DMRT taraf 5%. Hasil penelitian menunjukkan bahwa varietas memberikan pengaruh nyata pada peubah tinggi tanaman, diameter batang, jumlah cabang, jumlah polong dan bobot 100 biji, sedangkan perbedaan konsentrasi pupuk organik cair berpengaruh nyata pada parameter waktu berbunga, jumlah polong isi, bobot polong, bobot biji, bobot berangkasan, dan produktivitas kedelai. Interaksi antara varietas dan pupuk organik cair hanya memberikan pengaruh nyata pada parameter jumlah cabang. Secara umum, faktor pemupukan secara terpisah memberikan hasil produktivitas yang lebih baik meskipun tidak selalu berbeda nyata secara statistik.

The study aimed to analyze the effect of Liquid Organic Fertilizer (LOF) concentration on the growth and productivity of two different soybean varieties. The study used a two-factor Randomized Block Design Factorial Design. The first factor was the Anjasmoro and Sirapan Village local soybean varieties, while the second factor was variations in liquid organic fertilizer concentrations, including control treatments, 7.5 ml/L, 10 ml/L, and 12.5 ml/L. Observed variables included germination rate, plant height, stem diameter, number of leaves, number of branches, flowering age, leaf chlorophyll content, number of filled pods, number of empty pods, pod weight, seed weight, 100-seed weight, shoot weight, and soybean productivity. Data were analyzed using analysis of variance (ANOVA) and the DMRT test at the 5% level. The results showed indicate that the variety significantly influenced parameters such as plant height, stem diameter, number of branches, number of pods, and 100-seed weight, whereas differences in liquid organic fertilizer concentration significantly affected parameters including flowering time, number of filled pods, pod weight, seed weight, total biomass weight, and soybean productivity. The interaction between variety and liquid organic fertilizer had a significant effect on only one growth parameter. In general, the fertilization factor alone yielded better productivity results, although these were not always statistically significant.
