Abstract

Persoalan mendasar budidaya tembakau adalah semakin menurunnya produktivitas lahan, disebabkan oleh sistem pertanian monokultur dan intensif penggunaan pupuk anorganik yang berakibat penurunan kesuburan tanah. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk organik cair limbah pertanian yaitu daun lamtoro, daun tithonia, kulit umbi singkong dan buah pepaya terhadap pertumbuhan dan hasil tanaman tembakau serta membandingkan dengan hasil penelitian yang telah dilakukan di lokasi yang sama. Penelitian menggunakan metode eksperimen, Rancangan Acak Lengkap 4 perlakuan, yaitu pemberian POC daun Tithonia, daun lamtoro, kulit umbi singkong dan buah pepaya dengan 10 ulangan. Data diolah menggunakan SPSS versi 26 dan uji lanjut DNMRT taraf 5%. Dari penelitian didapatkan bahwa pengaplikasian POC daun lamtoro menghasilkan tembakau dengan tinggi, jumlah daun, panjang daun dan lebar daun lebih besar dibanding POC lain. Kesimpulan penelitian adalah limbah pertanian yang difermentasi menjadi pupuk organik cair dapat dimanfaatkan sebagai pupuk karena dapat menghasilkan tembakau dengan tinggi, jumlah daun, panjang daun, lebar daun dan diameter batang yang tidak berbeda dengan tembakau yang diaplikasikan pupuk anorganik (pupuk buatan).

Abstract

Coffee is an important agricultural commodity with increasing global demand, so optimizing the growth of coffee seedlings, especially during the seedling phase, is crucial to increase productivity. The use of natural plant growth regulators offers an environmentally friendly and economical solution. This study aims to evaluate the effect of natural plant growth regulators from onion extract and bean sprout extract on the growth of robusta coffee seedlings (Coffea canephora L.) during the seedling phase. The study was conducted using a Randomized Block Design (RBD) with three treatments, namely control, onion extract, and bean sprout extract. The parameters measured included plant height, stem diameter, and number of leaves for six weeks. Data were analyzed using ANOVA and BNT test at the 5% level. The results showed that both natural plant growth regulators significantly increased the growth of coffee seedlings compared to the control. Bean sprout extract gave the best results for plant height (16.75 cm), while onion extract was superior in increasing stem diameter (4.65 mm) and number of leaves (12.20). Statistical analysis confirmed significant differences between treatments and controls for all parameters. Thus, the use of onion and bean sprout extracts as natural growth regulators has proven effective in increasing the growth of coffee seedlings in the seedling phase, offering an environmentally friendly and economical alternative for optimizing the growth of coffee seedlings.

Abstract

Robusta coffee seeds (Coffea canephora) exhibit relatively long physiological dormancy, which often constrains seedling production. One approach to accelerate seed germination is soaking seeds in gibberellic acid (GA₃). This study aimed to evaluate the effect of GA₃ soaking duration at 250 ppm on germination and early seedling growth of robusta coffee seeds. The experiment was arranged in a Completely Randomized Design (CRD) with a single factor, namely GA₃ soaking duration, consisting of five levels: 0, 12, 24, 36, and 48 hours. Observed parameters included time to dormancy breaking, germination percentage, root length, hypocotyl length, percentage of cotyledon opening, and fresh weight of seedlings. Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at the 5% significance level. The results showed that GA₃ soaking duration significantly affected dormancy-breaking time, germination percentage, root length, hypocotyl length, and seedling fresh weight, but had no significant effect on cotyledon-opening percentage. Soaking seeds in a GA₃ solution (250 ppm) for 24–36 hours produced the best response, as indicated by faster dormancy-breaking, higher germination percentage, and better early seedling growth. Excessive soaking duration tended to reduce treatment effectiveness. Therefore, an appropriate GA₃ soaking duration is recommended to improve robusta coffee seedling establishment.
