Penekanan Perkembangan Penyakit Bercak Ungu Pada Bawang Merah (Allium Ascalonicum L.) Oleh Cendawan Mikoriza Arbuskular pada Lahan yang Diberi Biochar Cangkang Kemiri dan Pupuk Kandang Kambing

Abstract

Hasan basril lawolo NPM 158210075 "the development of an (allium ascalonicum l.) By the mikoriza arbuscular fungus on the land which is given biochar's shell of the potato and goat pen manure." This thesis was under Dr. Ir's mother's guidance. Sumihar Hutapea, ms as head counselor and father to Dr. Ir. A. Rafiqi Tantawi, Ms. As a member of the tutor. The study has been set up for the growth center of the 1st annual district that stands on the no. 1 peratun street. The study was carried out from October to December 2019. The purpose of this study is to know the emphasis on the development of purple bloating disease of Onions (allium ascalonicum l) by the presentation of the mikoriza arbuscular fungus, recognizing the response of the biochar of the shell of the potato and the goat pen onto the field given biochar and the goat pen. The study is designed by a random group (rack) up to gross elements of mistreatment: (1). Mikoriza arbuscular force of 3 measures of treatment, C0= control (without cma), C1 = mikoriza arbuscular (30 gr/m2) or (300 kg/ha), C2 = mikoriza arbuscular (60 gr/m2) or (600 kg/ha). Biochar's shell shell consists of three degrees of B0 = control (without biochar), B1 = biochar (0.3 kg/m2) or (3 tons /ha), B2 = biochar (0.6 kg/m2) or (6 kg/m); (3) the goat pen (1 kg/m2) or (10 tons /ha), K2 = goat pen (2 kg/m) or (20 tons /ha). Thus obtained a combination of 3x3x2 = 18 combination of treatment. Each treatment was repeated twice, resulting in 36 experimental plots. Each experimental plot consists of 16 plants with five samples. Observable parameters: plant height (cm), number of leaves (blades), number of disease, number of saplings, wet weight per plot (gr) and dry weight per plot (gr). The result of this study was that mikoriza arbushad a real effect on disease intendence, giving biochar a a real influence on ruby weight /plot, the giving of kambimg outings to high and dry weight per plot of plants, the combination of biochar and goat - pen fertilizers having a real impact on the wet and dry weight of the plant.
