Abstract

Penelitian ini bertujuan untuk mengetahui dan mempelajari interaksi RPTT dan pupuk NPK serta mencari konsentrasi dan dosis perlakuan yang memberikan pengaruh yang terbaik terhadap pertumbuhan dan hasil tanaman kedelai varietas Dering 2. Percobaan dilaksanakan di kebun percobaan Fakultas Pertanian UNWIM pada bulan Februari hingga Juni 2023, ketinggian tempat 875 mdpl dan jenis tanah Andisol.  Percobaan ini menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri dari 2 faktor. Faktor pertama yaitu konsentrasi RPTT yang terdiri dari 4 taraf, yaitu: p0 = 0 ml L-1, p1 = 5 ml L-1, p2 = 10 ml L-1 dan  p3 = 15 ml L-1. Faktor kedua yaitu dosis NPK yang terdiri dari 4 taraf, yaitu n0= 0 kg ha-1, n1= 5 kg ha-1, n2= 10 kg ha-1 dan n3= 15 kg ha-1. Hasil penelitian menunjukkan tidak terjadi interaksi antara konsentrasi RPTT dan dosis pupuk NPK, secara mandiri konsentrasi RPTT 15 ml L-1 berpengaruh nyata terhadap bobot 100 biji, sedangkan dosis pupuk NPK 150 kg ha-1 berpengaruh terhadap jumlah daun umur 35 HST dan dosis 450 kg ha-1 berpengaruh nyata terhadap bobot 100 biji.Kata kunci : Kedelai, Konsentrasi Rizobakteria Pemacu Tumbuh Tanaman, Dosis Pupuk NPK

Abstract

Shallots are vegetable commodities whose economic value and needs are quite high in the country, this has caused a decrease in the value of shallot exports over the last 5 years. Therefore, it is necessary to increase shallot production in order to increase the export value of shallots again by using Plant Growth Promoting Rhizobacteria (PGPR) biological fertilizers containing good microorganisms that can produce phytohormones, help increase soil fertility and reduce pests. The research was conducted in the experimental land of the Faculty of Agriculture, Winaya Mukti University, Sumedang Regency. The research implementation time is from February 2023 to August 2023. The purpose of this study was to determine the effect of growth and yield of onion plants and obtain the best dose of bamboo root PGPR on the yield of onion plants of the Bima Brebes variety. The environmental design uses Group Random Design (RAK) consisting of 5 treatments (A = 0 L ha-1, B = 2 L ha-1, C = 4 L ha-1, D = 6 L ha-1, E = 8 L ha-1) and repeated 5 times. The results showed that the dose of PGPR bamboo roots had a significant effect on the yield of onion plants of the Bima Brebes variety on the observation parameters of the number of tubers per clump, the number of tubers per plot and the fresh weight of tubers per clump. No dose of bamboo root PGPR gave the best results, but one dose of PGPR showed better results at a dose of 6 L Ha-1 on observation of the number of tubers per plot.Keywords: Shallot, Bima Brebes, Dose, PGPRShallots are vegetable commodities whose economic value and needs are quite high in the country, this has caused a decrease in the value of shallot exports over the last 5 years.
