Abstract

This study aims to get the oil palm seedlings variety that were more tolerant to waterlogging stress duration. Research does in the experiments were undertaken at the Agriculture Faculty Station of Riau University from April to June 2016. Experiment done in the completely randomized design 3 x 3. The first factor was the Tenera varieties palm oil seedlings: AA-DP TOPAZ 1 (v1), Sungai Pancur I (v2) and DxP Simalungun (v3). The second factor was waterlogging stress duration: 30 days (g0), 50 days (g1) and 70 days (g3). Variables observed consisted of: seedling height, leaf midrib, stem diameter, canopy root ratio, seedling quality index and seedling dry weight. The results showed that, interaction between the varieties palm oil seedling with waterlogging stress duration was not significant. Effect of waterlogging stress duration take on all observed variables, but the varieties affects to height, number of leaves and dry weight of seedling. The varieties of oil palm seedlings more tolerant to 70 days waterlogging stress duration, compared 30 days or 50 days. The growth of Sungai Pancur I and DxP Simalungun palm oil seedling were better than AA-DP TOPAZ 1. Keywords: Tenera varieties palm oil seedling, waterlogging stress duration.

Abstract

This research was intended to find out the effect of interaction between AB mix nutrition and tofu liquid waste in order to get the best AB mix concentration and tofu liquid waste concentration for the plant growth and cucumber plant yield (Cucumis sativa L.) hidroponically. This research took place in the Green House of Faculty of Agriculture University of Riau during July to November 2017. This research was conducted experimentally by using complete randomized factorial design (RAL) which have two factors and three replication. Factor 1 the concentration of AB mix nutrition (K), where: K1 = 0 ml, K2 = 2 ml.l-1,K3 = 4 ml.l-1 and Factor 2 the concentration of tofu liquid waste (L) with: L1 = 20%, L2 = 40%, L3 = 60%, L4 = 80%. The result showed that, the interaction of AB mix concentration and tofu liquid waste indicated non significant effect on all parameters. The single factor of AB mix indicated non significant  effect on the length and the diameter of fruits but had significant effect on other parameters. In a single factor tofu liquid waste indicated a significant effect only on the length of fruits. Therefore, the application of 4 ml.l-1 of AB mix concentration and 60% concentration of tofu liquid waste indicated the best result of plant growth and the production of the cucumber.Keywords: AB mix nutrition, tofu liquid waste, cucumber, hydroponic
