Abstract
Description
The aim of the study was to determine the effect of biological fertilizers and NPK on the growth and production of soybeans. As an alternative to reducing the use of chemical fertilizers. The design used was a Factorial Randomized Block Design, which consisted of two factors, namely the Biological Fertilizer (H) with a dose of 82 ml of solution / plot consisting of 4 levels, namely: H0 = (control) , H1 = 2 Weeks After Planting, H2 = 3 Weeks After Planting, H3 = 4 Weeks After Planting and NPK Fertilizer Factor (N) with 3 treatment levels, namely N1 = 30 grams/plot (50% of recommended dose), N2 = 45 grams/plot (75% of the recommended dose), N3 = 60 grams / plot (100% of the recommended dose). The parameters observed were plant height, number of pods planted, number of pods per plot, number of seeds planted, number of seeds per plot, and weight of 100 seeds. The results showed that the application of biofertilizers had a significant effect on pod weight per plant, but had no significant effect on plant height, pod weight per plot, seed weight per plant, seed weight per plot, and weight of 100 seeds. soya bean. The best application of biological fertilizers was obtained in the H2 treatment, namely the provision of biological fertilizers 2 weeks before planting and given again 2 weeks of biological fertilizers after planting. The application of NPK fertilizer did not significantly affect plant height, pod weight per plant, pod weight per plot, seed weight per plant, seed weight per plot, and weight of 100 seeds. The best application of NPK fertilizer was obtained at treatment N3 = 60 grams/plot (100% of the recommended dose).
Penelitian bertujuan untuk mengetahui pengaruh pemberian pupuk hayati dan NPK terhadap pertumbuhan dan produksi tanaman kedelai. Sebagai alternatif pengurangan pemakaian pupuk kimia.Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) Faktorial, yang terdiri dari dua faktor yaitu Faktor Pemberian pupuk Hayati (H) dengan dosis 82 ml larutan / plot terdiri atas 4 taraf yaitu : H0 = (kontrol), H1 = 2 Minggu Setelah Tanam, H2 = 3 Minggu Setelah Tanam, H3 = 4 Minggu Setelah Tanam dan Faktor Pupuk NPK (N) dengan 3 taraf perlakuan yaitu N1 = 30 gram / plot (50% dari dosis anjuran), N2 = 45 gram / plot (75% dari dosis anjuran), N3 = 60 gram / plot (100% dari dosis anjuran).Parameter yang diamati adalah tinggi tanaman, jumlah polong per tanaman, jumlah polong per plot, jumlah biji pertanaman, jumlah biji per plot, dan berat 100 butir biji. Hasil penelitian menunjukkan bahwa pemberian pupuk hayati berpengaruh nyata terhadap berat polong per tanaman, tetapi berpengaruh tidak nyata terhadap tinggi tanaman, berat polong per plot, berat biji per tanaman, berat biji per plot, dan berat 100 butir biji tanaman kedelai. Pemberian pupuk hayati terbaik di peroleh pada perlakuan H2 yaitu pemberian pupuk hayati 2 minggu sebelum tanam dan di berikan lagi pupuk hayati 2 minggu setelah tanam. Pemberian pupuk NPK tidak berpengaruh nyata terhadap tinggi tanaman, berat polong per tanaman, berat polong per plot, berat biji per tanaman, berat biji per plot, dan berat 100 butir biji. Pemberian pupuk NPK terbaik diperoleh pada perlakuan N3 = 60 gram / plot (100 % dari dosis anjuran
