Respon Pertumbuhan Dan Produksi Tanaman Kacang Kedelai (Glycine Max L.) Pada Pemberian Poc Bonggol Pisang Dan Pupuk Cangkang Kerang Hijau

Abstract

Kedelai (Glycine max L.) merupakan salah satu jenis tanaman sayuran-sayuran yang memiliki potensi yang sangat besar sebagai sumber protein nabati. Penelitian ini bertujuan untuk mengetahui pengaruh pupuk organik cair bonggol pisang dan cangkang kerang hijau terhadap pertumbuhan dan produksi tanaman kacang kedelai. Metode penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Faktorial yang terdiri dari 2 faktor, yaitu : POC Bonggol Pisang dan Cangkang Kerang Hijau. Pupuk Organik Cair Bonggol Pisang terdiri dari 4 taraf perlakuan, yaitu: P0 = Tanpa Perlakuan POC Bonggol Pisang, P1 = 200 ml/liter air POC Bonggol Pisang, P2 = 400 ml/liter air POC Bonggol Pisang, dan P3 = 600 ml/liter air POC Bonggol Pisang. Sedangkan Pupuk Cangkang Kerang Hijau terdiri dari 4 taraf, yaitu: C0 = Tanpa Perlakuan Pupuk Cangkang Kerang Hijau, C1 = 280 gram/plot Pupuk Cangkang Kerang Hijau, C2 = 420 gram/plot Pupuk Cangkang Kerang Hijau, dan C3 = 560 gram/plot Pupuk Cangkang Kerang Hijau. Variabel pengamatan meliputi : tinggi tanaman (cm), jumlah daun (helai), jumlah cabang (cabang), umur mulai berbunga (hari), jumlah polong per tanaman sampel (polong), jumlah polong per plot (polong), bobot polong per tanaman sampel (g), bobot polong per plot (g), bobot 100 biji (g), volume akar (ml), dan serangan hama dan penyakit. Hasil penelitian menunjukkan POC bonggol pisang berpengaruh sangat nyata pada tinggi tanaman (cm), jumlah polong per tanaman sampel (polong), jumlah polong per plot (g), bobot biji per tanaman sampel (g) dan pupuk cangkang kerang hijau berpengaruh sangat nyata pada tinggi tanaman (cm), jumlah polong per tanaman sampel, dan jumlah polong per plot. Soybean (Glycine max. L.) is one type of vegetable crop that has enormous potential as a source of vegetable protein. This study aims to determine the effect of liquid organic fertilizer banana hump and green mussel shells on the growth and production of soybean plants. This research method uses a factorial randomized block design (RAK) which consists of 2 factors, namely: Liquid Organic Fertilizer Banana Hump and Green Clam Shell. Liquid Organic Fertilizer for Banana Hump consists of 4 levels of treatment, namely: P0 = Without Liquid Organic Fertilizer Banana Hump treatment, P1 = 200 ml/liter of water Liquid Organic Fertilizer Banana Hump, P2 = 400 ml/liter of water Liquid Organic Fertilizer Banana Hump, and P3 = 600 ml/liter water Liquid Organic Fertilizer Banana Hump. Meanwhile, Green Clam Shell Fertilizer consists of 4 levels, namely: C0 = No Green Clam Shell Fertilizer Treatment, C1 = 280 grams/plot Green Clam Shell Fertilizer, C2 = 420 grams/plot Green Clam Shell Fertilizer, and C3 = 560 grams/plot Green Clam Shell Fertilizer. Observation variables included: plant height (cm), number of leaves (strands), number of branches (branches), age of flowering (days), number of pods per sample plant (pods), number of pods per plot (pods), pod weight per plant sample (g), weight of pods per plot (g), weight of 100 seeds (g), root volume (ml), and pest and disease attacks. The results showed that POC Banana Bonggol had a very significant effect on plant height (cm), number of pods per sample plant (pods), number of pods per plot (g), seed weight per sample plant (g) and green mussel shell fertilizer had a very significant effect on plant height (cm), number of pods per sample plant, and number of pods per plot.
