Pengaruh Pemberian Kompos Paitan (Tithonia Diversifolia) dan Nanopartikel Cangkang Telur Terhadap Pertumbuhan Dan Produksi Bawang Merah (Allium Ascalonicum)

This study aims to determine the effect of giving Paitan (Tithonia diversifolia) compost, Eggshell Nanoparticles, and a combination of giving Paitan (Tithonia diversifolia) compost and eggshell nanoparticles simultaneously on growth and production of Shallots (Allium ascalonicum). This study used a factorial randomized block design (RBD) with two research factors, namely giving paitan compost (P0 = without applying fertilizer; P1 = 0. 5 kg / plot; P2 = 1 kg / plot; P3 = 1. 5 kg / plot) and giving egg shell nanoparticles (N0 = without giving nanoparticles; N1= 1 g / plot; N2 = 1. 5 g / plot; N3 = 2 g / plot), repeated 2 times.  eggshell nanoparticles had a very significant effect on plant height at the age of 2. 4 and 5 WAP, on the number of leaves at 3 WAP, and had a significant effect on plant height at 3 and 6 WAP, on the number of leaves 2 and 4 WAP but not significant effect on plant height 7 and 8 WAP, on the number of leaves at 5 to 8 WAP, and other parameters. The combination effectiveness of paitan compost and eggshell nanoparticles had a very significant effect on the number of leaves at 2 and 3 WAP, and had a significant effect on the number of leaves at 4 WAP but had no significant effect on plant height at 2 to 8 WAP, for the number of leaves at 5 to 8 MST and on other parameters
