Endomycorrhiza palys important role in nutrient uptake of agricultural plant. The purpose of this study was to investigate the presence of endomycorrhiza associated with non-legume plants, i.e.:Zea mays L., Solanum lycopersicum L., Capsicum frutescens L., Brassica oleracea L. and Brassica juncea (L.) Czern,  in agricultural area in Koya Barat, Jayapura. Survey was done before collecting root and soil samples. The root of those non-legume plants were cleaned and stained using method developed by Kormanic and Mc.Graw. Wet seaving method was done to analyze soil samples. The result showed that those non-legume plants were infected by endomycorrhiza. The highest infection percentage was on corn (Zea mays L.), while the lowest was on cabbage (Brassica oleracea L.). Furthermore, from spore identification, 14 species of endomycorrhiza were found on the rhizosphere of those plants which were grouped into genus Glomus (5 species), Gigaspora (2 species), Acaulospora (2 species) and Scutelospora (1), however 4 species were remain unidentified yet. Therefore further study should be done to elucidate this problem.Key words: endomycorhiza, exploration, non-legum, Koya Barat, Jayapura.

Agricultural intensification has led to an elevated use of pesticides and fertilizers such as urea, without considering the negative effects these products can cause, such as acidification of the soil and the entry of lead (Pb) into the trophic chain. The objective of this research was to determine the effect of urea on the absorption of lead (Pb) in the leaf structure of corn (Zea mays L.), spinach (Spinacia oleracea L.), and cabbage (Brassica oleracea L.). These three plant species were exposed to five different concentrations of urea and a constant concentration of Pb in the form of Pb acetate for 93 days. The effect of urea and Pb was determined through analysis of the leaf structure. The results showed an increase in the dry weight of corn, whereas in spinach (T4) (1.5 g urea kg-1 of soil plus 0.5 g Pb kg-1 of soil) dry weight decreased as well as the fresh weight and foliar area. An increase in the chlorophyll index in corn, spinach, and cabbage was observed in the treatments with urea, and there was an influence on soil acidification. We also observed that spinach concentrated more Pb (T4) in its foliage at higher rates of N application. The idiosyncratic nature of the crop combined effects of Pb and N highlights the need for more research on this subject.
