This study aims to evaluate the effect of rice husk biochar and coffee husk biochar, to evaluate difference effect of rice husk biochar and coffee husk biochar and to know effect of difference dose of rice husk biochar and coffee husk biochar on phosphate and zinc, and rice growth in the paddy soil with high total P. The research was conducted on the greenhouse, Faculty of Agriculture, University of North Sumatra, Medan. The soil which used from the paddy soil in Lubuk Dendang, Perbaungan, Serdang Bedagai which has the high total P. The experiment was carried out using completely randomized design with 7 treatment : Control; 10 ton/ha rice husk biochar; 20 ton/ha rice husk biochar; 30 ton/ha rice husk biochar; 10 ton/ha coffee husk biochar; 20 ton/ha coffee husk biochar; 30 ton/ha coffee husk biochar. The Analysis of data used the analysis of variance and contrast orthogonal test.Experimental results showed that rice husk biochar and coffee husk biochar has significant effect on levels of Zn plant, but not significant effect on soil pH, available P, soil Zn HCl 25%, levels of P plant, P uptake, Zn uptake and the growth of plants. Coffee husk biochar has more potential than rice husk biochar to increasing levels of Zn plant. Dose of coffee husk biochar 20-30 ton/ha increasing levels of Zn plant higher than 10 ton/ha.

The research was aimed to know that accumulation of lead in soil and mustard due to urban waste compost application. The researh was held in gauze house and analyzed in Balai Pengkajian Teknologi Pertanian (BPTP) Laboratory, North Sumatera in April -July 2016. The research used randomized block design factorial with two treatment factors those are the depth of layers of urban waste compost with 3 level of treatment ; S1 (upper layer), S2 (middle layer), S3 (bottom layer) and growing media composition with 5 level of treatment ; M0 (100% soil), M1 (25% compots + 75% soil), M2 (50% compost and 50% soil), M3 (75% compost + 25% soil), M4 (100% compost) with 3 replications. The result showed that giving25% urban waste compost can increase of production of mustard, soil pH, soil C-organic, total Pbsoil and Pb in plants and it’s value exceeds the threshold. The depth of layers of urban waste compost significant effect on total Pb soil and Pb in plants and it’s value exceeds the threshold. Interaction amount of compost and the depth of layers of urban waste compost were not significant increased of production of mustard, but significant increased of soil pH, soil C-organic, total Pbsoil and Pb in plants.

ABSTRACT Goosegrass (Eleusine indica) on rubber fields at Rambutan estate PTPN III had been sprayed using glyphosate for 28 years continuously. Lately it was reported that the herbicide glyphosate was no longer effective to control E.indica in that area. The objective of this study was to determine the spread and resistance levels of E. indica populations to glyphosate found in 14 Divisions of Rambutan Estates. The 14 populations were compared to a population collected from the University of Sumatera Utara where no herbicides had been sprayed previously. The plants were sprayed with 480 g a.i IPA glyphosate at 4-5 leaf stage. Experiment was arranged using fully randomized design non factorial, with the populations of, ESU0, ESU5.1, ESU5.2, ESU5.3, ESU5.4, ESU5.5, ESU5.6, ESU5.7, ESU5.8, ESU5.9, ESU5.10, ESU5.11, ESU5.12, ESU5.13, and ESU5.14, of which each population was made in 4 replications.Results showed that of 14 populations of goosegrass, 8 populations were “very resistant” and 6 populations were “resistant” to glyphosate. Thus the entire populations have developed to become resistant to glyphosate. Keywords : Distribution, eleusine indica, glyphosate, resistance, rubber estate

Rubber (Hevea brasiliensis Muell. Arg) is one of the superior plantation commodities that has a huge potential in Indonesia. Rubber development is centered on the areas with rainfall 2500-4000 mm / year. In that area the rubber faces a lot of land competition issues and also the disease that need to maximize the potential of the low annual rainfall area. This research was conducted on citizen plantations in Aek Godang village, Sihapas Hulu, North Padang Lawas , on March-April 2016, aimed to test the influence of giving mycorrhiza to Osmoregulation PB260 clone rubber seedlings on lands with drought stress that has given an organic matter. This research using random sampling in non-factorial, with mycorrhiza treatment with M symbol that consists of 3 levels ; M0 = without mycorrhiza, M1 = Acaulospora 100g / plant,M2 = Glomus + Acaulospora (1: 1) 100g / plant, with each level of treatment has 9 reiteration. The Variables observed were consist of leaf water potential, osmotic pressure and turgor pressure. The results showed that the distribution of mycorrhiza has a significant effect on the improvement of leaf water potential, but it has no a significant effect on the improvement of turgor pressure of rubber plant.

Publisher : Universitas Sumatera Utara

A pot trial at the screen house of College of Agriculture, University of North Sumatera was carried out to evaluate the effects of varied levels of chicken manure and lime of CaCO3 towards a number of soil chemical properties and corn growth on Inceptisol of Kwala Bekala. The trial was 3 x 3 factorial arranged in a randomized complete block design. Treatments included three levels of chicken manure: 0, 5 and 10 t/ha and three levels of lime and three replications to meet 27 experimental units, respectively. The results showed that 10 t/ha of chicken manure significantly increased the availability of phosphorus in soil and also the absorption of phosphorus by plants. The results also showed that at 4.47 t/ha lime of CaCO3 significantly increased the soil pH. However, there was no interaction effect between chicken manure and lime of CaCO3. Keywords: chicken manure, corn growth, Inceptisol, lime of CaCO3
