Suryanto Suryanto, Reni Mayerni, Nasrez Akhir

Abstract


This research has been carried out at the Experimental Farm Faculty University Muhammadiyah South tapanuli, indonesian country, from may until August of 2017. The purpose of this research is to know the influence of KCl fertilizer dose and type of mulch against the results of the sweet potato. The design used was 4 x 3 faktors in a randomized blok design with 3 replications. The main factor is the dose of KCl fertilizer consisting of four levels, and the second factor is the use of mulch that consists of three levels. The first dose of KCl fertilizer factor (K) with 4 levels, namely: K1 = 150 kg/ha, K2 = 300 kg/ha, K3 = 450 kg/ha, K4 = 600 kg/ha. The second factor is the treatment of mulch (M) with 3 levels namely: M1 = Without mulch, M2 = rice straw Mulching, M3 = silver black plastic Mulch.The data were analyzed statistically observations according to test F at 5% level. If count is greater than F table 5% means different influential real then continued with Duncan's New Multiple Range Test (DNMRT). The next dose of KCl fertilizer effect of the real against the diameter of the tuber, tuber weight per plant and the production of tubers per hectare. The best treatment is the use of KCl fertilizer dose 11.25 g/plant (450 kg/ha).
