Abstract

Okra is highly nutriuos vegetables which can be developed in Riau with using Histosol and Ultisol land by addition Mahogany leaf ash. The aim of this research is to find out the influence of Mahogany leaf ash on medium Histosol, Ultisol, and the mixture and obtain best dose for each medium to growth and yield of Okra plants. The experiment was conducted in Experimental Field of Faculty of Agriculture, Riau University, in Mei until September 2018 experiments multiplied with 3x4 factorial arengged according to Nested design (Nested). The first factor was application various medium, namely Histosol, Ultisol the mixture (1:1). The second factor was addition several ash doses, namely 0,25 recomended dose, 0,5 recomended dose, 0,75 recomended dose and 1 recomended dose (Histosol = 6 ton.ha-1, Ultisol = 12 ton.ha-1, and the mixture = 9 ton.ha-1). The result of this reasearch showed addition several ash doses on various medium has not significant to almost all parameter except stem diameter. The Addition of recomended ash dose on medium Histosol only increas fruits yields 15,66% with weights 150,17 g, medium Ultisol 32,55% with weights 114,00 g, and the mixture 29,17% with weights 121,00 g compared with addition 0,25 recomended dose.Keywords: Okra, Ash, Histosol, Ultisol

Abstract

This study aims to determine the effect of the combination of GA3 and young coconut water and to get the best treatment on the growth of occulationorange. The research was conducted at the Experimental Garden of the Faculty of Agriculture, University of Riau, from June to October 2019. The study used a completely randomized design (CRD), consisting of concentrations of growth regulators (Z), namely: Z1 = application ofGA33%, Z2 = application of coconut water young 75%, Z3 = combinationGA3 2% and young coconut water 25%, Z4 = combinationGA3 2% and young coconut water 50%, Z5 = combinationGA31% and young coconut water 25%, Z6 = combination GA3 1% and 50% young coconut water, consisting of 4 replications. Parameters observed were shoot emergence, number of branches, length of branches, increase in rootstock diameter, number of leaves and branch dry weight. The results showed that the combination of GA3 2% and 50% young coconut water showed the fastest shoot emergence time was 25.75 days, increasing the number of leaves namely 21.50 strands and branch dry weight of 1.65 grams. The combination of GA3 1% and 50% young coconut water showed better results in increasing the length of the branches and the dry weight of the branches.Keywords: gibberellin, young coconut water, oranges and budding.

Abstract

Cocoa (Theobroma cacao L.) is one of the plantation commodities that had important role in economic activity in Indonesia as a raw material commonly used for the pharmaceutical, cosmetic, food and beverage industries. Efforts to increase cocoa production on Ultisol soil can required by applying Mucuna bracteata compost and NPK fertilizer. This research is an experimental research that is arranged according to factorial Completely Randomized Design (CRD) by giving a combination of Mucuna bracteata compost treatment (4 levels) and NPK fertilizer (3 levels) with three replication. The fertilizer of Mucuna bracteata compost was carried out one week before planting the sprouts according to the treatment dose. NPK fertilizer was applied one week and three weeks after planting the sprouts according to the treatment dose. The variables observed were seed height, stem diameter, number of leaves every four weeks starting from 4 WAP to 16 WAP while root volume, root shoot ratio and seed dry weight were carried out at the end of the study. Observations were made on all plants. The results showed that the fertilizer of Mucuna bracteata compost had an effect on the observed variables, namely seed height, number of leaves, stem diameter, root volume, root crown ratio and seed dry weight in Ultisol soil. The fertilizer of NPK fertilizer had no effect on seed height, stem diameter, root volume, root crown ratio and dry weight of cocoa seedlings in Ultisol soil. The combination of Mucuna bracteata compost and NPK fertilizer affected the growth of cocoa seedlings in Ultisol soil. The fertilizer of 100 g / plant Mucuna bracteata compost and 4 g / plant NPK fertilizer is the best dose for growing cocoa seedlings in Ultisol soil.Keywords: cocoa, Ultisols, Mucuna bracteata, NPK
