Performance of some populations of maize (Zea mays L.) on peat soil applied Sludge and ash of oil palm

Abstract

The objective of this study obtained the appearance of the vegetative and reproductive character of some maize populations on peat soil with pH criteria of 5.9 and application of sludge and ash of oil palm. The research was conducted at Tanjung Rejo, Medan city from April to August 2017. This research used a Randomized Block Design (RBD) with 2 treatment factors. The first factor was 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 was planting medium consisting of 3 levels is M1 (peat), M2 (peat + ash of oil palm), M3 (peat + sludge). The results showed that the interaction between planting media with some populations of maize had a significant effect on plant height character. The best media was found in M3 (peat + sludge). The best population based of the highest plant were population C (CLA106 x NEI 9008) and D (CLA 16 x CLA 84).
