Abstract

This study aims to determine the effect of various types of manure and urea fertilizer dosage on growth and production of black soybean (Glycine soja L.). The model used is a factorial Randomized Block Design (RAK) consisting of 2 factors. The first factor is the type of manure consisting of 3 levels, namely: K1 = Chicken manure (75 gr polybag-1), K2 = Goat manure (75 gr polybag-1) and K3 = Cow manure (75 gr polybag-1). The second factor is the dose of Urea fertilizer consisting of 3 levels, namely: U1 = 2.50 gr polybag-1, U2 = 3.75 gr polybag-1 and U3 = 7.50 gr polybag-1. Parameters observed consisted of plant height, number of branches, age of flowering, weight of 100 seeds, root length, number of root nodules. Based on the results of the study, it can be stated that the type of manure had no significant effect on plant height, number of branches, age of flowering, weight of 100 seeds, root length and number of root nodules of black soybean plants. The dose of urea fertilizer had no significant effect on plant height, number of branches and age of flowering, but significantly increased weight of 100 seeds, root length and number of root nodules. The interaction of type of manure and dose of urea fertilizer had no significant effect on all observed parameters.

Abstract

This research was conducted at the Biology Laboratory, Faculty of Agriculture, Universitas Katolik Santo Thomas, Medan. This study aims to determine the potential of fragrant pandan leaf extract as a vegetable pesticide in controlling armyworm pests. This study used a non-factorial completely randomized design (CRD). The treatment factor was fragrant pandan leaf extract (Pw) which consisted of 5 treatments and 4 replications, namely: Pw0 = (control/without giving fragrant pandan leaf extract), Pw1 = 20 ml of fragrant pandan leaf extract, Pw2 = 40 ml of pandan leaf extract fragrant, Pw3 = 60 ml of fragrant pandan leaf extract and Pw4 = 80 ml of fragrant pandan leaf extract, each treatment added with 100 ml of distilled water. The results showed that the highest percentage of mortality (100%) at 108 hours after application (JSA) was found in the treatment of 80 ml of fragrant pandan leaf extract + 100 ml of aquadest. The fastest death time of 50% of armyworms was found in the treatment of 80 ml of fragrant pandan leaf extract + 100 ml of aquadest, which was 30 JSA.

Abstract

This research aims to determine the effect of doses of oil palm shell ash and dolomite on the growth and production of maize plants. This study used a factorial randomized block design consisting of two factors. The first factor is the dose of palm shell ash (A) which consists of four levels, namely: (A0) = 0 g (0 tons/ha), (A1) = 30 g/polybag (6 tons/ha), (A2) = 60 g/polybag (12 tonnes/ha) and (A2) = 90 g/polybag (18 tonnes/ha). The second factor was dolomite (D) dosing which consisted of three levels: (D0) = 0 g (0 tons/ha), (D1) = 15 g/polybag (3 tons/ha) and (D2) = 30 g /polybag (6 tonnes/ha). Parameters observed were plant height, number of leaves, stem diameter, leaf area, cob length without cob, cob diameter without cob, cob weight with husk, cob weight without cob and straw weight. The effect of the dose of oil palm shell ash depends on the dose of dolomite which is shown in the diameter of the cobs without husks, in treatment D0 the dose of palm ashes 78.07 g/polybag resulted in a maximum cob diameter without husks of 3.95 cm, treatment D1 increased linearly, treatment D2 the dose of palm shell ash 85.03 g/polybag resulted in a maximum diameter of cobs without husk of 3.98 cm. The largest straw weight was 311.30 g with a dose of shell ash of 56.93 g/polybag.

Abstract

This study aims to determine the effect of planting media (Top soil Ultisol, Sand and Goat Manure) on the growth of Porang (Amorphophallus muelleri) seedlings. This study used a non-factorial randomized block design (RAK). The treatment factor was the composition of the growing media which consisted of 7 levels of treatment, namely: A = Topsoil ultisol 100%, B = 100% goat manure, C = 100% sand, D = Topsoil ultisol + goat manure + sand (1 : 1: 1 : 1), E = Topsoil ultisol + goat manure + sand (1 : 2: 1), F = Topsoil ultisol + goat manure + sand (2 : 1: 1), G = Topsoil ultisol + goat manure + sand ( 1:1:2). The parameters observed were the percentage of germination, plant height, stem diameter and leaf area of the plant. Based on the results of the study, it can be stated that the composition of a mixture of topsoil ultisol, goat manure and sand has a significant effect on the growth of porang seedlings. The best growth of porang seedlings was found in the composition of topsoil, sand and goat manure with a ratio of 1: 1: 2 (E). The application of goat manure and sand on top soil ultisol had a significant effect on plant height, stem diameter and leaf area, but had no significant effect on the percentage of seedling growth.

Abstract

The average potency of palm production were 24, 22, 20, and 18 ton fruit fresh bunch (FFB) each year along 25 years in class of land 1, 2, 3 and 4. In fact, the real production of palm is often below of planning (estimation). Production evaluation ought to be done as dayly, weekly, monthly, threemonthly, sixmonthly, and yearly. Several points of production evaluation of palm as like: comparing with last year production, tendency of production, palm condition in field, maintainance of palm, harvest system, and solving some problems in field. The object of production evaluation would be done with overall of plantation, every afdeling, groups of years planting (groups of age plantings), and every blocks land area. The result of evaluation would be used as based information to repair/maintain palm, to increase the product and to stabilize the high product, or in other term to optimize the production as good as land potency.

Abstract

The research aims to test the media plant cocopeat-top soil as well dose SP-36 fertilizer against growth soya bean black malika (Glycine soja.L ). To know the impact of the growth of oil palm seedlings (Elaesis guineensis Jacq.) in dose using rice husk charcoal biochar on some type of soil in pre- nursery. The research uses the Design Random Factorial (DRF) consist of 2 factors . The first factor is a mixture of cocopeat - top soil planting media . The second one is SP-36 dose . Based on the results of the study, it can be stated that, cocopeat planting media with topsoil had no significant effect on plant height at 4, 5, 6 and 7 mst, significantly affected the number of branches aged 7 and 8 mst and plant root length, but had no significant effect on flowering age, weight of 100 seeds, and number of root nodules. The dose of SP-36 fertilizer had no significant effect on plant height at the ages of 2, 3, 8, 11, 12 and 13 mst, flowering age, weight of 100 seeds and root length, but had no significant effect on number of branches and number of root nodules. The interaction of cocopeat growing media with topsoil and the dose of SP-36 fertilizer had no significant effect on all observed parameters .The dose of SP-36 fertilizer had no significant effect on plant height at 2, 3, 8 11 and 12 mst, flowering age, weight of 100 seeds and root length, but had no significant effect on number of branches and number of root nodules.

Abstract

This study aims to determine the response of corn plants to doses of oil palm shell ash on Ultisol soil. This study used a non-factorial Randomized Block Design (RBD) with the treatment being a dose of palm shell ash (A), which consisted of 7 levels, namely: A0 = 0 g/polybag (Control), A1 = 15 g/polybag, A2 = 30 g/polybag, A3 = 45 g/polybag, A4 = 60 g/polybag, A5 = 75 g/polybag, A6 = 90 g/polybag. Parameters observed were plant height, number of leaves, stem diameter, leaf area, cob length without cob, cob diameter without cob, cob weight with husk, cob weight without cob, and strawweight. Based on the results of the study it can be stated that the higher the dose of oil palm shell ash, it will be followed by the increase in plant height, leaf area, stem diameter, leaf area, cob length without cob, cob diameter without cob, cob weight with cob, cob weight without cob. and strawweight.
