Abstract

Lettuce (Lactuca sativa L.) is highly favored among people with high economic status. In addition to being rich in various minerals and vitamins, lettuce is often used as a garnish in culinary dishes. This study aimed to determine the relationship between fertilizer types and planting media composition on the growth and yield of lettuce. The experiment was designed using a completely randomized design (CRD) with two factors: fertilizer type (J) and planting media composition (K), with treatments repeated three times. Data were analyzed using analysis of variance (ANOVA), followed by the least significant difference (LSD) test at a 5% significance level. The results indicated a significant interaction between treatments on parameters such as plant height, number of leaves, stem diameter, and root length. The combination treatment J3K3 yielded the best results. Fertilizer type significantly influenced plant height, number of leaves, stem diameter, leaf area, crown fresh weight, root length, and crown dry weight, with J3 (vermicompost fertilizer) being the most effective. Planting media composition significantly affected the number of leaves, stem diameter, and leaf area, with K3 (a composition of 1 kg of beach sand and 5 kg of organic fertilizer) producing the best outcomes. Sayuran selada (Lactuca sativa L.) sangat popular di kalangan masyarakat dengan ekonomi tinggi. Selain, kaya akan berbagai mineral dan vitamin, selada kerap dijadikan sebagai garnis disetiap hidangan makanan. Tujuan penelitian adalah untuk mengetahui apakah jenis perlakuan pupuk dan komposisi media tanam berhubungan dengan pertumbuhan dan hasil selada. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dua faktor (RAL) yakni Jenis pupuk (J) dan komposisi media tanam (K) kemudian perlakuan diulang sebanyak tiga kali. Data penelitian dianalisis menggunakan metode analysis of variance (ANOVA) yang dilanjutkan dengan uji beda nyata terkecil (BNT) 5%. Hasil penelitian menunjukkan terdapat interaksi nyata antar perlakuan terhadap parameter tinggi tanaman, jumlah daun, diameter batang dan panjang akar. Perlakuan kombinasi J3K3 menunjukkan hasil terbaik. Perlakuan jenis pupuk berpengaruh nyata terhadap tinggi tanaman, jumlah daun, diameter batang, luas daun, berat segar tajuk, panjang akar, dan berat kering tajuk, dengan perlakuan J3 (pupuk kascing) yang terbaik. Perlakuan komposisi media tanam memberikan pengaruh nyata terhadap jumlah daun, diameter batang, dan luas daun, dengan komposisi K3 (komposisi 1 kg pasir pantai + 5 kg pupuk organik) menunjukkan hasil terbaik.

Abstract

Optimal growth of Land spinach in an aquaponic system requires the selection of superior varieties and appropriate substrates. Aquaponic systems combine aquaculture and hydroponics and offer a sustainable approach to organic crop cultivation. However, studies on substrate interaction and variety in water spinach growth are still limited. This study aims to evaluate the effect of interaction between substrate and water spinach variety on plant growth and yield in an aquaponic system, focusing on potential applications in modern agriculture. A Completely Randomized Design (CRD) was used in this study with three levels of substrate, namely rockwool (M1), cocopeat (M2), and a mixture of cocopeat-charcoal (M3). Three levels of variety, namely Bisi (V1), Shanghai (V2), and Bangkok (V3), are repeated three times. Data analysis showed no significant interaction between substrate type and variety on plant height growth, dry weight, stem diameter, and leaf area at various stages of observation. These results indicate that the aquaponic system does not explicitly require certain water spinach varieties for different substrates, making it easier for farmers to manage cultivation. These findings support the flexibility of aquaponics practices, making them more efficient and easy to adopt in modern agriculture. The study confirms that aquaponics systems allow a versatile approach to kale cultivation without the constraints of a particular substrate or variety. With the efficiency offered, this system could be an innovative solution to increase sustainability and productivity in future agriculture. Pertumbuhan optimal kangkung dalam sistem akuaponik membutuhkan pemilihan varietas unggul dan substrat yang sesuai. Sistem akuaponik, yang memadukan akuakultur dan hidroponik, menawarkan pendekatan berkelanjutan untuk budidaya tanaman organik. Namun, studi tentang interaksi substrat dan varietas terhadap pertumbuhan kangkung masih terbatas. Penelitian ini bertujuan mengevaluasi pengaruh interaksi substrat dan varietas kangkung terhadap pertumbuhan dan hasil tanaman dalam sistem akuaponik dengan fokus pada potensi penerapan dalam pertanian modern. Rancangan Acak Lengkap (RAL) digunakan dalam penelitian ini dengan tiga taraf substrat, yaitu rockwool (M1), cocopeat (M2), dan campuran cocopeat-arang (M3) serta tiga taraf varietas, yaitu Bisi (V1), Shanghai (V2), dan Bangkok (V3) yang masing-masing diulang sebanyak tiga kali. Analisis data menunjukkan tidak adanya interaksi signifikan antara jenis substrat dan varietas terhadap pertumbuhan tinggi tanaman, berat kering, diameter batang, dan luas daun pada berbagai tahap pengamatan. Hasil ini menunjukkan bahwa sistem akuaponik tidak secara khusus memerlukan varietas kangkung tertentu untuk jenis substrat yang berbeda, sehingga mempermudah petani dalam pengelolaan budidaya. Temuan ini mendukung fleksibilitas dalam praktik akuaponik, menjadikannya lebih efisien dan mudah diadopsi dalam pertanian modern. Studi ini menegaskan bahwa sistem akuaponik memungkinkan pendekatan serbaguna untuk budidaya kangkung tanpa batasan susbstrat atau varietas tertentu. Dengan efisiensi yang ditawarkan, sistem ini dapat menjadi solusi inovatif untuk meningkatkan keberlanjutan dan produktivitas dalam pertanian masa depan.

Abstract

The application of plant-growth promoting rhizobacteria (PGPR) offers an eco-friendly approach to enhancing crop growth and productivity. This study assesses the effects of PGPR derived from bamboo roots on growth metrics (e.g., stem diameter and branch count) and yield traits (e.g., pod count, fresh and dry pod weights, and harvested bean weight) of mung bean (Vigna radiata L.). Bamboo roots were selected as a unique source of PGPR because it fosters a favourable environment for beneficial microorganisms, enhancing nutrient absorption in plants. Conducted under controlled conditions, this experiment followed a completely randomized design, tested six PGPR dosage: 0 ml/polybag (H0), 10 ml/polybag (H1), 20 ml/polybag (H2), 30 ml/polybag (H3), 40 ml/polybag (H4), and 50 ml/polybag (H5) applied weekly. Results revealed significant growth promotion during the late vegetative phase, with H3 yielding optimal outcomes improved stem diameter, branch number, pod count, and seed dry weight. Higher dosages (H4, H5) negatively impacted growth, potentially due to microbial competition, nutrient imbalance, or stress. This eco-friendly method demonstrates the potential of bamboo-derived PGPR to boost mung bean productivity, supporting food security and profitability. Further studies should investigate its long-term effects and adaptability across diverse crops and farming systems, enhancing its utility for sustainable agriculture.
