APLIKASI NIGHT SOIL + ZEOLIT GUNA MENINGKATKAN KUALITAS PERTUMBUHAN DAN HASIL BAWANG MERAH VARIETAS BIRU LANCOR (Allium ascalonicum) DI TANAH PASIR PANTAI
Abstract
The research was conducted to understand the effect of night soil and zeolite application as a substitution material for manure and to determine the most effective and efficient doses of night soil and zeolite on the quality of growth and yield of shallot in coastal sandy soil. The study was carried out from February 2016 through June 2016 at Experimental Farm of Universitas Muhammadiyah Yogyakarta.
This research was designed using Completely Randomized Design (CRD) using single factor, consisted of seven treatments i.e (A) 20 ton of manure per hectare, (B) 10 ton of night soil per hectare, (C) 20 ton of night soil per hectare, (D) 10 ton of night soil per hectare + 4 ton of zeolite per hectare, (E) 20 ton of night soil per hectare + 4 ton of zeolite per hectare, (F) 10 ton of night soil per hectare + 8 ton of zeolite per hectare, (G) 20 ton of night soil per hectare + 8 ton of zeolite per hectare.
The results showed that the treatments of all doses of night soil which combined with zeolite could improve means of number of leaves, fresh weight of shoots, dry weight of shoots, shallots weight per clump and productivity of shallots in coastal sandy soil when compared with 20 tons of manure per hectare. The treatment of 10 ton of night soil per hectare could improve effectively and efficiently the quality of growth and yield of shallots in coastal sandy soil.
