Abstract

This study aims to determine the breaking dormancy of candleberry seeds which soaked with organic growth regulator Basmingro and its effect on seed viability. Research will be carried out in Limba U2, South City, Gorontalo City, for about 6 months. The materials used are candleberry seeds, organic PGR Basmingro. Candleberry seed soaked in a solution of organic PGR Basmingro in 5 treatment concentration (control (without PGR); PGR 0.02%, 0.03%, 0.04% and 0.05%) and 4 replications. Data were analyzed quantitatively by using Environmental Design Complete Randomized Design (CRD) and analysis of variance (ANOVA). Data are significantly different tested further by Duncan Multiple Rate Test (DMRT). The results are not significantly different, because no germination of candleberry seeds, caused by yet influential PGR is treated to break dormancy due to hard seed coat seed candleberry. So that further research needs to be done by increasing the dose and duration of soaking candleberry seeds with PGR organic Basmingro.

Abstract

The research aims to obtain isolates from rhizosphere biocontrol agents that can inhibit the development coconut pathogen P. palmivora causes nutfall disease. The experiment was conducted in the laboratory Phytophatology Manado Palm Research Institute, isolation method with biocontrol agents and test the ability of antagonistic biocontrol agent against pathogenic isolates of P. palmivora in vitro. Obtained 30 isolates candidate biocontrol agent consisting of 17 isolates of bacteria and 13 fungal isolates. Of the 30 isolates were obtained six isolates were able to suppress the growth of pathogenic P. palmivora with a percentage of the inhibition of BHP2 80.89%, 41.27% BH2P4, TBL1P3 22%, BKN2P1 47.71%, 64.25% and isolates TBL2P3 TontaP3 of 72.66%.

Abstract

This study aimed to determine the N, P, and K nutrients uptakes of maize crops in Dutohe of Bone Bolango regency. Te research was carried out in Dutohe Village of Kabila Distric of Bone Bolango regency for about 6 months. The experimental design was following randomized block design that consist of 4 treatments (P+K, N+P, N+K) with 3 replications, so there are 12 plot units. Dosages of each treatment were 160 kg Urea, 54 kg TSP, and 90 kg KCl. The result from the experiment showed that minus one test has not significant effect to N and P uptakes, but has significant effect to K uptake.

Abstract

The aim of this study was to determine (1) the effect of N, P, and K fertilizers on the maize growth and (2) the best treatment combinations on the maize growth. The fertilizers method using minus one test in randomized block design pattern with four treatments and three replications. Dosages of each treatment were 160 kg Urea, 54 kg TSP, and 90 kg KCl. The results of this research showing that the minus one test of N, P, and K fertilizers has significant effect to plant high on 14 days after planting (DAP), 42 DAP, and 56 DAP, but has not significant effect on 28 DAP. This pattern was the same with leaf color parameters. , for leaf numbers has significant effect on 28 DAP only. The best treatment combination was N+K treatment or minus P.

Abstract

The aim of this study was to determine the effect of plant growth regulators GA3 administration of early maturing coconut embryo germination Salak (GSK) is not yet mature and to know the germination rate and germination, the embryo early maturing coconut Salak (GSK) is not yet mature. The method used in this research using Complete Randomized Design (CRD) with six treatments and three replications. Each treatment used 10 embryos that embryonic research is needed 180 Coconut GSK. The results indicate that the substance of growth regulators GA3 greatly affect the speed of germination and embryo germination of immature coconut GSK (which comes from the age of nine months). and the concentration of GA3 70 ppm gave the optimal results of germination rate, concentration of GA3 50 ppm to 80 ppm gave the same results germination

Abstract

The objective of this research was to study the respons of N, P, and K fertilizers and the best combination of it on the maize yields. The experimental design was following random block design that consist of 4 treatments with 3 replications, so there are 12 plot units. Dosages of each treatment were 160 kg Urea, 54 kg TSP, and 90 kg KCl. The result of this research showing that minus one test has significant effect to stem length, stem diameters, and all dry weigh, for 100 gain weigh has not significant effects. The best treatment combination was N+K treatment or minus P.

Abstract

Land utility for physic buildings on Gorontalo State University campus I has shown rasing significant trends. Whereas, the land was originally rice field productively and water catchments area. Consequently, its function is reduced due to the infiltration of water hampered. This study aimed to (a) determine the amount of soil infiltration rate, and (b) determine the amount of soil permeability. The study was conducted on six months in the campus 1 Gorontalo State University areas. The equipment consists of Guelph permeameter, rol meter, water bag, stop watch, soil bor and raffia. s, the materials consist of water and soil samples. Infiltration measurements carried out in a transect from the south to the north lines. Measurements will be performed at every five meters with two measurements (0-10 cm and 10-20 cm). On existing lines any building or standing crop, the measurement will be carried out on one side to detect the effect of distance and the soil variability. Parameters observed include water infiltration, and soil permeability. The result of this research shown that infiltration rate (i) and soil permeability (Ks) at campus 1 Gorontalo State University areas classified as very rapid. s, the highest of infiltration rate and soil permeability values was to 140 m distance or point 28 and the lowest was to 170 m distance or point 34.
