Abstract

The aim of this research was study the effect of soil types and compost to provide nutrients nitrogen and growth of corn plant. Nitrogen is an essential nutrient by the main source of organic material from corn required with high levels at the age of four weeks to optimum product in soils low levels of nitrogen. For it has done a research in the field screen Agriculture Faculty University of Sumatera Utara (± 25 m above sea level) in June-August 2012 by using a factorial Randomized Block Design in two factors: types of soils were entisols, inceptisol and ultisol and compost were control, straw compost + chicken manure, straw compost + cocoa fod compost, cocoa fod compost + chicken manure. Parameters measured were soil pH, soil C-organic, soil N-total, ratio of C/N soil, plant height, plant dry weight, N plant level and N-plant uptake.The results showed that the combination of various organic matter on the three soil types significantly affect to the C-organic, N-total soil, plant height, plant dry weight and N-plant uptake.

Abstract

The aim of this research to know the effect of seaweed liquid fertilizer (Sargassum polycystum) made ​​from waste materials on the growth and production of  mustard  (Brassica juncea L.) on ultisol. This research was held in gauze house, Chemistry/Soil Fertility Laboratory and Research Laboratory,  Agricultural Faculty, University of North Sumatra, Medan in June-September 2012. The sample of soil to used is ultisol. The research used a Completely Randomized Design (CRD) Non Factorial with nine treatments and three replications that are twenty-seven experimental units. Treatment consists of P0 (Control), Pa2 (EM-4 20 cc with liquid seaweed fertilizer every 2 days), Pa3 (EM-4 20 cc with liquid seaweed fertilizer every 3 days), Pa4 (EM-4 20 cc with liquid seaweed fertilizer every 4 days), Pa5 (EM-4 20 cc with liquid seaweed fertilizer every 5 days), Pb2 (EM-4 40 cc with liquid seaweed fertilizer every 2 days), Pb3 (EM-4 40 cc with liquid seaweed fertilizer every 3 days), Pb4 (EM-4 40 cc with liquid seaweed fertilizer every 4 days), Pb5 (EM-4 40 cc with liquid seaweed fertilizer every 5 days). The result of experiments showed that seaweed liquid fertilizer different is not real to pH of soil, C-organic of soil, N soil, K-exchange, C/N of soil. But, real different to the P-available of soil, fresh weight of plants, fresh weight of root, dry weight of plant and dry weight of root.

Abstract

This study aims to know the effect of Si on the availability of soil phosphate and silica, rice growthand production in the paddys soil with high total P . The research was conducted on the greenhouseand on the laboratory soil chemistry, Faculty of Agriculture, University of North Sumatra, Medan.The soil which used from the paddys soil in Tanjung Mulia Hilir, Medan Deli which has the hightotal P. The experiment was carried out using non-factorial randomized block design with treatmentcontrol, 3.4 g silica agrosil fertilizer/ plant, 4.8 g silica agrosil fertilizer/ plant, husk ash 3.4 g/ plantand 4.8 g husk ash / plant. The Analysis of data used the analysis of variance and contrast test.Experimental results showed that silica materials has significant effect on soil pH, maximum tillernumber and dry weight of grain, but not significant effect on available P, available Si, P – uptake, Si– Uptake, Plant Height, and Plant Dry Weight. Husk ask and Agrosil silica showed the same effectin the soil chemistry nature that’s the soil phosphate and silica availability.Keyword : silica material, paddy Soil, P, Si – uptake, rice growth and production
