Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian biofertilizer berbasis mikroba pelarut fosfat terhadap pertumbuhan dan hasil tanaman sawi pagoda (Brassica rapa L.). Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) satu faktor dengan 4 perlakuan dan 3 ulangan, sehingga diperoleh 12 unit percobaan. Perlakuan yang digunakan terdiri atas T0 sebagai kontrol tanpa pemberian pupuk, T1 sebagai pemberian pupuk anorganik NPK sesuai dosis rekomendasi, T2 sebagai pemberian biofertilizer MPF Tanatani dengan dosis 5 ml/L air, dan T3 sebagai pemberian biofertilizer MPF Tanatani dengan dosis 10 ml/L air. Parameter pengamatan meliputi tinggi tanaman, jumlah daun, dan bobot tanaman. Pengamatan pertumbuhan dilakukan pada 7, 14, 21, dan 28 hari setelah tanam (HST), sedangkan pengamatan hasil dilakukan pada saat panen. Data dianalisis menggunakan analisis ragam (ANOVA) pada taraf 5%. Apabila terdapat pengaruh nyata, dilanjutkan dengan uji Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa pemberian biofertilizer berbasis mikroba pelarut fosfat memberikan pengaruh terhadap pertumbuhan dan hasil tanaman sawi pagoda pada parameter yang diamati. Perlakuan dengan dosis biofertilizer yang memberikan hasil terbaik ditentukan berdasarkan hasil pengamatan dan analisis statistik. Kata kunci: Biofertilizer, Mikroba Pelarut Fosfat, Sawi Pagoda, Pertumbuhan, Hasil ================================================================================================== This study aimed to determine the effect of applying a phosphate-solubilizing microbe-based biofertilizer on the growth and yield of Brassica rapa L. (pagoda mustard). The study employed a single-factor Randomized Block Design (RBD) with four treatments and three replications, resulting in 12 experimental units. The treatments consisted of T0 (control/no fertilizer), T1 (inorganic NPK fertilizer at the recommended dosage), T2 (MPF Tanatani biofertilizer at a dosage of 5 ml/L of water), and T3 (MPF Tanatani biofertilizer at a dosage of 10 ml/L of water). Observed parameters included plant height, number of leaves, and plant weight. Growth observations were conducted at 7, 14, 21, and 28 days after planting (DAP), while yield observations were made at harvest. Data were analyzed using Analysis of Variance (ANOVA) at the 5% significance level. If a significant effect was found, the analysis was followed by Duncan’s Multiple Range Test (DMRT). The results indicated that the application of the phosphate-solubilizing microbe based biofertilizer influenced the growth and yield of pagoda mustard across the observed parameters. The biofertilizer dosage treatment yielding the best results was determined based on the observations and statistical analysis.
