Abstract

The objective of this research was to obtain morpho-physiological characters performances maize inbreed on acid soil condition. The experiment was conducted in a Nested Design with three replications. The first factor was environment, the second factor was 16 inbreds of maize. The experiment was conducted at two environments : acid soil with criteria of Al-dd 0.2 me.100 g-1 and acid soil with criteria of Al-dd 1.87 me.100 g-1. The results showed that tolerant maize inbreed on acid soil condition had small Anthesis Silk Interval and …fasterKeywords : introduction inbreed lines, morpho-physiological character, acid soil.

Abstract

Maize is one of the staple food crops in Indonesian that must be developed its genetic diversity. The objective of this study was to obtain the appearance of vegetative and reproductive character of some F1 maize populations on peat soil stress with pH criteria of 5.9 and peat soil with sludge and ash of oil palm. The research was conducted at Setiabudi field, Tanjung Rejo sub-district, Medan city from April to August 2017. This research used Randomized Block Design (RAK) with 2 treatment factors. The first factor is the population consisting of 5 levels:A (NEI9008 x CLA46), B: (NEI9008 x CLA106), C: (CLA106 x NEI9008),D: (CLA16 x CLA84), E: (CLA84 x NEI9008) and the second factor is planting medium consisting of 3 levels is M1 (peat soil), M2 (peat soil + ash of oil palm), M3 (peat soil + sludge). The results showed that the interaction of planting media with F1 population of maize plant had significant effect on plant height character. The best media is found in M3 (peat soil + sludge).

Abstract

The maize in indonesia mostly use land that is not fertile. The objective of the research was identified the selection character based on root morphology of hybrid maize (F1) in peat soil medium applicated with legume organic manure in rhizotron. The research was conducted at the greenhouse of Faculty of Agriculture, University of Sumatera Utara, from February until July 2017. The Randomized Block Design was used with two factors, the first factor is the population (V1, V2, V3, V4, V5) and the second factor is the planting medium (peat soil, peat soil + leucena, peat soil + mucuna). The parameters observed were: the number of root, the length of root, the diameter of root dispersed, the fresh weight of the canopy, the fresh weight of root and the dry weight of root. The result showed that the population F1 significantly affected the number of root, the volume of root, the fresh weight of root and the dry weight of root. The planting medium significantly affected the number of root, the length of root, the diameter of root dispersed, the volume of root, the fresh weight of the canopy, the fresh weight of root, the dry weight of root. Interaction between the population F1 NEI9008 x CLA46 (V5) and the planting medium peat soil + mucuna significantly affected the fresh weight of root. Keywords       : maize, legume organic manure, peat soil, root morphology, rhizotron

Abstract

The aim of this research was to test the growth of palm oil varieties seedlings with some concentration of nutrients. This research was conducted at Greenhouse Faculty of Agriculture University of Sumatera Utara, from August to October 2017. The research design used  randomized block design (RBD) with 2 factors. The first factor was varieties consist of 3 varieties namely DxP Avros, DxP Langkat, and DxP Yangambi. The second factor is the concentration consisting of 4 levels  (8 HS, 1 HS, 1,2 HS and 1,4 HS). The observed variables were plant height (6, 8, 10, and 12 weeks after planting), number of leaves, stem diameter, root number and root length. The results showed that varieties significantly different to the plant height, stem diameter, and root length. The different concentration of nutrients had no significantly effect to all observed variables, and there was no interaction between the two treatments. 6 observed variables had high heritability at plant height 6, 10, and 12 weeks after planting, number of leaves 8 weeks after planting, stem diameter, and root length characters.
