ABSTRACT

Shallots (Allium ascalonicum L.) is one of the main vegetable commodities in Indonesia and has many benefits. This study aims to determine the yield of shallot production due to administration of petro bioferil and phonska doses on peatlands and to obtain the best doses of biofertile petro and phonska in increasing shallot production on peatlands. This research was carried out on Jalan A. Yani, Kelurahan Landasan Ulin Timur, starting from September  November 2020. The design used was a 2-factor Randomized Block Design (RAK), the first factor was petro biofertility (b) which consisted of 3 treatment levels, namely b1 (controI), b2 (180 kg/ha-1 or 18 g/pIot) and b3 (360 kg/ha-1 or 36 g/pIot), the second factor was phonska (p) with 4 treatment levels, namely p1 (88 kg/ha-1 or 8.8 g/pIot), p2 (184 kg/ha-1 or 18.4 g/pIot), p3 (272 kg/ha-1 or 27.2 g/pIot), p4 (360 kg/ha-1 or 36 g/pIot). The results showed that the combination treatment of petro biofertil and phonska had an effect on tuber weight loss but had no effect on the total stover weight per plot, the number of is tubers per clump, the stover wet weight per clump, and the dry weight of the stover per clump. Meanwhile, the single petro biofertil treatment had an effect on the number of tubers/cIump and tuber weight Ioss, but had no effect on the weight of the whole stover/pIot, the wet weight of the stover per cIump and the dry weight of the stover/cIump.
