Abstract

This research was aims to determine the growth and production performance of several soybean varieties (Glycine max L.) in the palm oil palm oil compartment. The specific objectives of this study are 1) to determine the growth and production performance of several soybean varieties grown in the oil palm gates of TBM. 2) Determine the morphological characteristics of the appearance of some soybean varieties. This research has been carried out in the Experimental Garden of the Faculty of Agriculture, Kuantan Singingi Islamic University for 4 months. This study used a Completely Randomized Block Design (RCBD) consisting of 5 treatment levels and 3 groups, so that 15 unit experimental units were obtained. The treatment level consists of A = Variety Demas 1, B = Dena Varieties 1, C = Argo Mulyo Varieties, D = Devon Varieties 1, E = Devon Varieties 2. The results of the study were statistically tested using SAS version 9.0. give real influence. Based on the results of further tests with Duncan Multiple Range Test (DMRT) at a level of 5%, the plant height parameter of Devon 1 variety was significantly different from other varieties, the total number of pod parameters of Demas 1 variety was significantly different from other varieties, the grain weight parameters and the weight of 100 grains of Devon 2 variety are significantly different from the varieties of Argo Mulyo, Devon 1, Dena 1, and Demas 1.

Abstract

Hydroponic cultivation of melon plants with a fertigation system using ground water is one of the cultivation technologies that is expected to improve the quality and production of crops. Fertigation technology (fertilizer and irrigation) using autopot is an irrigation system allow to provide irrigation water by self-watering system by not using electric power so that the fertigation system is more efficient. The purpose of this study was to determine the effect of the impact of groundwater quality on the quality of melon (Cucumis melo L.) plants. The research method used is descriptive method. The quality parameters of the melon used in this study were water content, carbohydrate, protein, fat, ash, vitamin C and sweetness (% brix). The results of research on ground water quality show that the quality of ground water used is included in the category of non-polluted, which means that the water has good quality. The results showed the quality of melon has an average value of 95.19% fruit water content, 1.99% carbohydrate content, 1.37% protein content, 0.88% fat content, 0.57% ash content, vitamin C 6 , 91%, and total dissolved solids (sweetness) 9.4 0brix. The quality of the melon is classified as low quality according to SNI 7883-2013. The results of the ground water quality and the quality of the melon shows if the ground water affects the quality of the melon plants.

Abstract

The production of the double haploid plant in vitro through anther culture technique is a plant breeding technique used to obtain pure strain rapidly. A variety of pretreatment has been reported to induce callus and regenerate planlets efficiently. This study aims at describing the influence of cold anther pretreatment towards the callus formation of curly red chili pepper (Capsicum annuum L.). This research was conducted in the laboratory of Genetics and Breeding, Faculty of Agriculture and Animal Science, Universtas Islam Negeri Sultan Syarif Kasim Riau. The explants used are anther of local genotype of curly red chili pepper. The anthers are stored at low temperatures (4 °c) with different time intervals of 0, 24, 48 and 72 hours. The results showed that the percentage of highest callus formation was obtained at 24 and 72 hours length storage, ie 50%. Cold pretreatment of 72 hours anther storage results in a faster callus with a percentage of the highest yellowish white callus color of 17.65% and a compact structure. The cold pretreatment with 72 hours anther storage is the most optimal acceleration in the development stage of anther culture and induces te formation of curly red chili pepper (Capsicum annuum L.) local genotypes.

Abstract

The aim of this study was to identify the chemical compound methanol extract of entomopathogenic fungus Beauveria bassiana from insect walang sangit and the chemical compound roots of red chili plants that were able to stimulate the growth of chilli plants after being applied with entomopathogenic fungus   B. bassiana through seed immersion inoculation using GCMS method. The chemical compound identified as a growth booster in   B. bassiana fungus isolates from the insect walang sangit is an Acetic acid Ethanoic acid Ethylic acid Glacial acetic acid CH3COOH, Hexadecanoic acid, methyl ester (CAS) Methylpalmitate Uniphat A60, n-Hexadecanoic acid Hexadecanoic acid n-Hexadecoic acid Palmitic acid, Dianhydromannitol and Ergosta-5,7,22-trien-3-ol, (3.beta., 22E) - (CAS) Ergosterol (CAS), while the chili root contains Acetic acid Ethanoic acid Ethylic acid Glacials acetic acid CH3COOH, Hexadecanoic acid, methyl ester (CAS) Methyl palmitate Uniphat A60, n -Hexadecanoic acid Hexadecanoic acid Palmitic acid, 8, 11- octadecadienoic acid, methyl ester (CAS) METHYL 8, 11-OCTADECADIENOATE, (23S)-ethylcholest-5-en-3.beta.-ol.s It can be concluded that some of the chemical compounds in methanol extracts identified in chili roots have similarities with chemical compounds that exist in   B. bassiana entomopathogenic fungus which are potential as stimulers of chili plant growth

Abstract

Through the nursery process with certain treatments can be produced quality seeds. Application of Mucuna bracteata compost and Azotobacter on growing media in polybags is one alternative that expected to increase plant growth. This study aimed to determine the effect of M. bracteata compost and Azotobacter and its combination on growth and nitrogen levels of oil palm seedlings. This research was conducted at STIPAP Medan in December 2018 - June 2019 with a Factorial Randomized Block Design (RBD). Treatment compost (K) 3 levels ie K0, K1 and K2 and Azotobacter (A) with 3 levels are A0, A1 and A2. M. bracteata treatment had a very significant effect on seedling height, number of leaves, shoot dry weight and root dry weight. Azotobacter treatment did not significantly affect the parameters of observation, increasing levels of leaf N 13-15%. Interaction compost and Azotobacter treatment had no significant effect. The best treatment is the K2A2 of 1.2 kg of compost and 30 ml of Azotobacter each oil palm seedlings planted in the polybag.
