Efektifitas Penggunaan Plant Growth Promoting Rhizobakteria (Pgpr) Dan Biourine Sapi Terhadap Pertumbuhan Dan Produksi Tanaman Bawang Merah (Allium Ascalonicum L.)

Abstract

Bawang merah (Allium ascalonicum L.) merupakan salah satu komoditas tanaman holtikultura yang banyak dikonsumsi masyarakat sebagai campuran masak setelah cabai. Selain sebagai campuran bumbu masak, bawang merah juga dijual dalam bentuk olahan seperti ekstrak bawang merah, bubuk, bawang goreng, sebagai bahan obat untuk menurunkan kolestrol, gula darah, mencegah pengumpulan darah, menurunkan tekanan darah serta mempelancar aliran darah salah satunya dengan pemberian pupuk PGPR dan Biourine Sapi. Metode penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Faktorial yang terdiri dari 2 faktor dengan 16 kombinasi perlakuan dan 2 ulangan. Faktor-faktor yang diteliti merupakan faktor pertama perlakuan pupuk PGPR terdiri dari 4 taraf. P0 = control, P1 = 10 ml/liter, P2 = 20 ml/liter, P3 = 30 ml/liter. Faktor yang kedua Biourine Sapi terdiri dari 4 taraf yaitu U0 = control, U1 = 20 ml/liter, U2 = 30 ml/liter, U3 = 40 ml/liter. Parameter yang diamati dalam penelitian ini adalah, tinggi tanaman,jumlah daun,berat biomassa,jumlah umbi,berat basah dan berat kering. Hasil penelitian ini menunjukan bahwa Pemberian PGPR berpengaruh tidak nyata terhadap berat biomassa per tanaman sampel, berat biomassa per plot, jumlah umbi per tanaman sampel, jumlah umbi per plot, berat basah umbi per tanaman sampel, berat basah umbi per plot, berat kering umbi per tanaman sampel dan berat kering umbi per plot. Tetapi berpengaruh nyata terhadap tinggi tanaman dan jumlah daun tanaman bawang merah. Pemberian konsentrasi Biourine sapi berpengaruh tidak nyata terhadap tinggi tanaman, berat biomassa per tanaman sampel, berat biomassa per plot, jumlah umbi per tanaman sampel, jumlah umbi per plot, berat basah per tanaman sampel, berat basah per plot, berat kering umbi per tanaman sampel dan berat kering per plot. Tetapi berpengaruh nyata terhadap jumlah daun tanaman bawang merah. Kombinasi PGPR dan konsentrasi biourine sapi berpengaruh tidak nyata terhadap seluruh parameter pengamatan pertumbuhan tanaman bawang merah. Shallots (Allium ascalonicum L.) are one of the horticultural crop commodities that are widely consumed by the public as a cooking mixture after chili. Apart from being a mixture of cooking spices, shallots are also sold in processed forms such as shallot extract, powder, fried shallots, as medicinal ingredients to lower cholesterol and blood sugar, prevent blood pooling, lower blood pressure and improve blood flow, one of which is by administering PGPR fertilizer. and Bovine Biourine. This research method uses a factorial randomized block design (RAK) consisting of 2 factors with 16 treatment combinations and 2 replications. The factors studied were the first factor of PGPR fertilizer treatment consisting of 4 levels. P0 = control, P1 = 10 ml/liter, P2 = 20 ml/liter, P3 = 30 ml/liter. The second factor of Cow Biourine consists of 4 levels, namely U0 = control, U1 = 20 ml/liter, U2 = 30 ml/liter, U3 = 40 ml/liter. The parameters observed in this research were plant height, number of leaves, biomass weight, number of tubers, wet weight and dry weight. The results of this study showed that PGPR administration had no significant effect on biomass weight per sample plant, biomass weight per plot, number of tubers per sample plant, number of tubers per plot, wet weight of tubers per sample plant, wet weight of tubers per plot, dry weight of tubers per sample plants and dry weight of tubers per plot. But it has a real effect on plant height and number of leaves of shallot plants. Giving cow Biourine concentration had no significant effect on plant height, biomass weight per sample plant, biomass weight per plot, number of tubers per sample plant, number of tubers per plot, wet weight per sample plant, wet weight per plot, dry weight of tubers per sample plant. and dry weight per plot. But it has a real effect on the number of leaves of shallot plants. The combination of PGPR and cow biourine concentration had no significant effect on all observed parameters of shallot plant growth.
