Abstract

This research aims to determine the effect of doses of oil palm shell ash and dolomite on the growth and production of maize plants. This study used a factorial randomized block design consisting of two factors. The first factor is the dose of palm shell ash (A) which consists of four levels, namely: (A0) = 0 g (0 tons/ha), (A1) = 30 g/polybag (6 tons/ha), (A2) = 60 g/polybag (12 tonnes/ha) and (A2) = 90 g/polybag (18 tonnes/ha). The second factor was dolomite (D) dosing which consisted of three levels: (D0) = 0 g (0 tons/ha), (D1) = 15 g/polybag (3 tons/ha) and (D2) = 30 g /polybag (6 tonnes/ha). Parameters observed were plant height, number of leaves, stem diameter, leaf area, cob length without cob, cob diameter without cob, cob weight with husk, cob weight without cob and straw weight. The effect of the dose of oil palm shell ash depends on the dose of dolomite which is shown in the diameter of the cobs without husks, in treatment D0 the dose of palm ashes 78.07 g/polybag resulted in a maximum cob diameter without husks of 3.95 cm, treatment D1 increased linearly, treatment D2 the dose of palm shell ash 85.03 g/polybag resulted in a maximum diameter of cobs without husk of 3.98 cm. The largest straw weight was 311.30 g with a dose of shell ash of 56.93 g/polybag.

Abstract

This study aims to determine the effect of planting media (Top soil Ultisol, Sand and Goat Manure) on the growth of Porang (Amorphophallus muelleri) seedlings. This study used a non-factorial randomized block design (RAK). The treatment factor was the composition of the growing media which consisted of 7 levels of treatment, namely: A = Topsoil ultisol 100%, B = 100% goat manure, C = 100% sand, D = Topsoil ultisol + goat manure + sand (1 : 1: 1 : 1), E = Topsoil ultisol + goat manure + sand (1 : 2: 1), F = Topsoil ultisol + goat manure + sand (2 : 1: 1), G = Topsoil ultisol + goat manure + sand ( 1:1:2). The parameters observed were the percentage of germination, plant height, stem diameter and leaf area of the plant. Based on the results of the study, it can be stated that the composition of a mixture of topsoil ultisol, goat manure and sand has a significant effect on the growth of porang seedlings. The best growth of porang seedlings was found in the composition of topsoil, sand and goat manure with a ratio of 1: 1: 2 (E). The application of goat manure and sand on top soil ultisol had a significant effect on plant height, stem diameter and leaf area, but had no significant effect on the percentage of seedling growth.
