Abstract

Chili (Capsicum annnum L.) is one of the horticultural commodities that has economic value. The aim of the research was to determine the effect of root extract of tubal (Derris elliptica) on various concentration levels to control Trips pavispinnus in red chili plants. The treatment tried is three extra concentrations of the tubal root; 10, 20, and 30 g of tubal root / water and one treatment without tubal roots as a control. The treatment was designed using a randomized block design with three replications. Rensposes observed were percentages of Trips pavispinnus mortality. The results showed that the extract of the root of the tuba can control the pest of Trips pavispinnus. The concentration of 10 g / L of water can kill the Trips pavispinnus to 74.42% on the day after application. To be able to prevent the loss of red chilli plants due to a series of  Trips pavispinnus, farmers can take advantage of extracts from the root of the tube, and are an environmentally friendly pest control method.Keywords: Chili, Derris elliptica, Tuba root, Trips pavispinnus

Abstract

Waxed vegetable plants (Saccharum edule) have a variety of species, can be found in several regions in Indonesia. This study aims to determine the types of vegetable candles in West Halmahera Regency, North Maluku Province. The research was carried out in nine sub-districts, 36 villages and involved 108 farmer owners. Research uses exploration and identification methods. Variables observed included stem shape, stem color, stem length, and plant height, as well as the color and length of the flower. The results of the study found that there were five types of vegetable candles namely short white, long white, long yellow, short yellow, and long white with reddish tree trunks. The five types of plants can be found throughout the sub-districts in West Halmahera Regency, Maluku Province.Keywords: West Halmahera, Saccharum edule, Wax vegetable

Abstract

Potatoes (Solanum tuberosum L.) which are comonly grown  in the highland with Andisols require organic and inorganic fertilizers to maintain soil health  and increase yield. The purpose of field experiment  was to obtain information on the effect of vermicompost with and without NPK fertilizer  on soil acidity,  soil phosphor (P) availability and P uptake in potatoes shoot; as well as yield and quality of tuber. The experimental design was a randomized block design with eight treatments and three replication. The treatment consisted of a combination of vermicompost doses (5 and 10 t/ha)  with NPK fertilizer doses (0; 0.5 t/ha and 1 t/ha). The two control treatments were 1) without fertilizer and 2) the method of fertilizing local farmers included 10 t /ha chicken manure and 1 t/ha NPK fertilizer. This experiment verified  that vermicompost and NPK fertilizer increased plant height as well as soil P availability and acidity compared to those of control. Vermicompost has not yet substitute chicken manure to obtain the same tuber production although the percentage of marketable tuber was quite similar.  Keywords : Andisols, NPK Fertilizer, Phosphorus, Potato, Vermicompost.

Abstract

Low soil fertility and the presence of damping off disease which is a inhibiting factor in the nursery of tomato plants. This can be overcome by utilizing the biological agent Trichoderma harzianum based on solid organic matter (Trichocompost). The aim of the study was to determine the effect of giving Trichocompost and obtain the optimal Trichocompos dose to reduce the intensity of damping off disease and increase the growth of tomato seedlings. The treatments tried were Trichocompos with doses of 20, 40 and 60 tons/ha, designed using a complete randomized design with 10 replications. The plant response observed was the intensity of the disease; height, fresh weight and dry weight of canopy; length, fresh weight and root dry weight. The results showed that the monitoring of Trichocompost can reduce the intensity of damping off disease to 54.80% and increase the growth of tomato seedlings. The recommended Trichocompos dosage is 60 tons/ha or as much as 30 g/1 kg of soil. The results of this study can be used to increase agricultural production and also a solution in an environmentally friendly and sustainable farming system.Keyword: Biocontrol, Tomato Trichocompos, Trichoderma harzianum

Abstract

The research to determine the effect of Azolla pinnata dry weight and nitrogen-fixing endophytic bacteria on the chemical properties of soil and plants and the growth of corn plants on Inseptisols from Jatinangor. This experiment was carried out in the greenhouse of the Faculty of Agriculture, Padjadjaran University, Jatinangor, West Java. The experiment design was Randomized Block Design (RDB) in factorial pattern consisted of two factors and three replications. The first factor was dosage of Azolla pinnata compost consisted of four levels (0 g pot-1, 12.5 g pot-1, 25 g pot-1, 37.5 g pot-1). The second factor was nitrogen-fixing endophytic bacteriaconsisted three levels: without nitrogen-fixing endophytic bacteria, just used nitrogen-fixing endophytic bacteria Acinetobacter sp., used nitrogen-fixing endophytic bacteria Pseudomonas sp. The results showed that there were interactions between Azolla pinnata and N2-fixing endophytic bacteria on N concentration and N uptake of corn plants. Applicaton Azolla pinnata compost with a dosage of 37.5 g pot-1 equivalent to 6 tons ha-1 can produce the highest dry weight of corn plants. Both nitrogen-fixing endophytic bacteria and azolla compost have not been able to increase the total N of Jatinangor Insepticols.Keywords: Azolla pinnata, nitrogen-fixing endophytic bacteria, Acinetobacter sp.,   Pseudomonas sp., corn plant

Abstract

Tuber of Cassava (Manihot esculenta Crantz) is a source of food and industrial raw materials. The purpose of this study was to examine the effect of physical treatment of cuttings on the production of cassava plants. The treatment that was tried was the physical treatment of cuttings, by being tapered, chopped, scraped, and tapered and without treatment as a control. The study used a randomized block design with four replications. The responses observed were the number and weight of tubers, and the carbohydrate content. The results showed that the physical treatment of cuttings affected the number and weight of tubers, but did not affect the carbohydrate content. The highest number of tubers and the weight of tubers is found in the tubers of the plant with tapered cuttings. The average low number and weight of tubers from plants which were treated physically on cuttings and controls compared with the physical treatment of tapered cuttings was 40.54% number tuber and 48.35% weight tuber. The average carbohydrate content is 29.62%.Keywords: Cassava, cuttings, Manihot esculenta, production
