The Effectiveness of Spraying Nano Bone Ash and Palm Oil Empty Fruit Bunch Ash on Characteristics of Rice in Salibu System Plus Earthworms

Abstract

This study aims to determine the effectiveness of spraying nano bone ash and palm oil emty fruit bunch ash on characteristics of rice in salibu system plus earthworms. This research was carried out in the Agricultural Experiment Grenn House of the Muhammadiyah University of Yogyakarta in January to June2021.This study uses a single factor design arranged in a Complete Randomized Design (CRD), there are 4 treatm ents.Each tratments consisted of 6 plant samples with 3 replications namely: P1. Urea 250 kg/ha + SP-36 100 kg/ha + KCl 100 kg/ha + Earthworms, P2.Urea 250 kg/ha + SP-36 50 kg/ha + KCl 100 kg/ha + Nano Bone Ash concentration 0,2 % + Earthworms, P3. Urea 250 kg/ha + SP-36 100 kg/ha + KCl 50 kg/ha + Nano OPEFB concentration 0,3 %, P4.Urea 250 kg/ha + SP-36 50 kg/ha + KCl 50 kg/ha + Nano Bone Ash concentration 0,2 % and Nano OPEFB concentration 0,3 % + Earthworms. Plant of material obtained from previous rice planting. The results showed that the spraying particle of nano bone ash and palm oil empty fruit bunch ash in salibu system plus eart worms effect on the diversity of qualitative character :color leaf sheath (pale green; green and dark green), leaf blade (pale green and green) and colorof stem (yellowish green and green) and on the diversity of quantitative character : height of plant, number of tillers, number of productive tillers, weight of grainst per clump.
