Abstract

Status of Arbuscular Mycorrhizal Fungi in Different Farming Systems and Age of Oil PalmABSTRACT. A survey was conducted to determine the Arbuscular Mycorrhiza Fungi (AMF) spore population in rhizosphere soils and its root colonization of oil palm belonging to four age class (2-3months, 2 years, 7 years, and 10 years) at PTPN I Estate plantation and smallholder farmer plantation in Cot Girek Aceh Utara. The methods used were direct isolation. The result showed that there were 14 species of AMF belongs to genus Glomus identified according to spore morphology, eight species at PTPN I and six species at smallholder oil palm plantation. AMF spore density at PTPN I and smallholder oil palm was 17.35 and 17.80 spore per 50g soil, respectively. Oil palm at 7 years old resulted in better AMF population, i.e. 53,7 spore per 50 g Soil. AMF colonization at oil palm rhizospere in both farming systems were low, i.e. 5.4% (PTPN I) and 2.9% (smallholder). Farming system and age of oil palm influenced the AMF population and root colonization, Spore density did not positively correlate with root colonization at different farming systems and age of oil palm.

Abstract

Use of Guano and Fertilizer NPK to Improve Quality of Subsoil Media and Growth of Oil Palm SeedlingABSTRACT. Utilization of subsoil as a growing medium for the nursery is a challenge to replace the role of topsoil as media for oil palm nurseries mainly on main nursery. This research was aimed at studying the effects of organic Guano and inorganic NPK fertilizer on oil palm seedling growth on sub soil growing media. The experiment was conducted in a pot, arranged in a randomized complete block design (RCBD), factorial 4x3 with 3 replicates. There were two factors examined, 1) guano dose consisting of four levels, namely: 0 kg, 0.5 kg, 1.0 kg and 1.5 kg/polybags and 2) inorganic fertilizers NPK consisting of three levels, namely: 0, 15, and 30 g/polybags. The results showed that subsoil can be used for growing media with applications of fertilizer Guano and inorganic NPK fertilizer. Guano and NPK fertilizer affected several soil chemical properties, i.e. increase in soil pH, available total C and N and P, and cation exchange capacity (CEC) and affected growth of oil palm seedling at age 16 weeks after planting. The best combination for the best seedling growth was obtained at 1.5 kg Guano + 30 kg NPK

Testing of Simulation Model of Soybean Seed Vigor Growth on Saline Soil ABSTRACT. The purpose of this research are to examine growth capability of 5 soybean varieties and to find out is laboratory seed testing model may be use to simulate the growth capability of soybean planted at soil with salinity problem. It is expected through this research obstacle in quick screening of plant growth at saline soil being solved. This research conducted from April – December 2011 at Seed Laboratory and Experimental Station of Agricultur Faculty of Unsyiah and farmer soil at Blang Krueng village, Aceh Besar. Experimental designs used in this research were Factorial CRD for laboratory and Factorial CRBD for field experiment. There are 5 varieties of soybean (Bener Meriah local seed, Kipas Merah, Kipas Putih, Anjasmoro and Orba) and 2 germination medium/soil (normal and saline) being examine, with 3 replicates, resulting 30 units experiments. Result from field experiments show that there is a significant interaction between soybean varieties and soil salinity level to seed growth capability. At normal soil, differences in varieties did not resulting in differences in seed growth capabilities, otherwise at saline soil. According to seed growth capabilities, at normal soil farmers can used any variety available, depends on production level. But, at saline soil farmers have to use Bener Meriah local seed. Whilst result from laboratory experiment did not show interaction of treatments to germination capability of soybean seed, but each treatment show its significant effect. Normal soil and Bener Meriah local seed are the best at laboratory experiment. The correlation test show that there is no close relationship between germination capability at laboratory and growth capability at field experiment, indicates that the method at laboratory cannot be use as a representative model to seed growth from field experiment.
