Abstract

The purpose of this research was to evaluate the influence of some types of soil ameliorans (lime, sea mud and some types of soil microorganisms) on P nutrient and soybean root development in peat soil.  The experiment was carried out in the Greenhouse of Agriculture Faculty of USU, Soil Biology Laboratory, Central Laboratory of Agriculture Faculty of USU and Laboratory of Soil analysis at RISPA, from March to November 2011.  The experiment was arranged in a completely randomized design, consisted of 13 treatments and two replicates. The treatments included control, dolomite lime, sea mud, lime + sea mud, Bradyrhizobium, mos, Mycorrhizal isolate of peat soil, mycorrhizal isolate of mineral soil, Bradyrhizobium + mos, mos + mycorrhizal isolate of peat soil isolates, mos + mineral soil mycorrhizal isolate, Bradyrhizobium + mos + mycorrhizal isolate of peat soil, Bradyrhizobium + mos + mycorrhizal isolate of mineral soil. Variables observed included soil pH, soil P available, plant P uptake, and weight of root dry. Types of amelioran exerted significant effect on soil pH, but did not exert significant effects on soil P available,  plant P uptake, and weight of dry root.

Abstract

The research was conducted at Post Harvest Laboratory of Indonesian Tropical Fruit Research Institute (ITFRI) from March to May 2010. The design used was a randomized complete block design with 4 replicates. Papaya genotypes tested were  BT-01, BT-02, BT-03, and BT-04. The results showed that papaya genotypes of  BT-01, BT-02, BT-03, and BT-04 were not significantly different each other on physical fruit characters i.e. fruit length, fruit width, fruit weight, and stem length.  However, the thinnest fruit flesh was found at BT-3 genotype and the thicknest flesh was at BT-2 genotype. The lowest fruit cavity was found at genotype BT-1 and the highest was at the BT-2.  The lowest hardness of fruit skin and flesh  was found at genotype BT-4 and the highest hardness of skin was at BT-3,  while the highest hardness of flesh was at BT-1 and BT-2.  Chemical quality of total dissolved solid, vitamin C, acid content, and water content was not significantly different among the four genotypes BT-1, BT-2, BT-3, and BT 4.

Abstract

This study was aimed at determining the appropriate growing medium composition and foliar fertilizer concentration and their interaction on growth and yield of lettuce. The experiment was arranged in a randomized complete block design (RCBD), consisting of two factors, i.e. the growing media composition and foliar fertilizer concentration. The first factor consisted of the composition of the soil and manure by volume ratio (3:1, 3:2, and 3:3) and the second factor consisted of foliar fertilizer concentrations (0, 2, 4 mL/L of water ). The results showed that the growing media composition soil+manure (3:3) was the best in increasing crop height, leaves number, leaf length, leaf width and yield at 35 day after planting, while the best concentration for those parameters was 4 mL/L of water. Based on the interaction, the best leaf number of lettuce was found at growing media composition soil+manure (3:3) with the concentration of foliar fertilizer 4 mL/L of water.

Abstract

The research was aimed at determining a critical period of soybean in competition with weeds. The experiment was conducted in Seunebok Baro Village, Sub-District Cot Girek, District Aceh Utara, from January to May 2013. The experiment was arranged in a randomized complete block design.  Factor evaluated was a period weed competition with 14 levels and three replications.  Variables observed were growth plant component, yield component, and weed compositions.   The results showed that period weed competition affected growth plant component and yield component.   Critical period of soybean variety Kipas Merah in competition with weeds occurred at 2 - 6 weeks after planting.  Dominant weed species were Dichrocephala integrifolia, Mimosa pudica, Ipomoea triloba, Ageratum conyzoides, Cleome rutidosperma, and Axsonopus compressus.  Minimum scale of weed control for soybean variety Kipas Merah can be carried out from 2 until 6 weeks after planting for preventing yield loss.

Abstract

The experiment was conducted at the Laboratory of Plant Pathology Faculty of Agriculture, Syiah Kuala University from February to June 2013. The purpose of study was to evaluate the survival of T. harzianum and T. virens after cohabiting with soil borne pathogenic fungi (Fusarium sp, Rhigidoporus sp, and Sclerotium sp) as well as the type of interaction. Trichoderma fungi and fungal pathogens were grown on PDA in vitro, and then observed their growth after being reisolated on 3 different growth zones. The results showed that T. harzianum and T. virens  growing with Fusarium sp were capable to grow over the space. It was evident from the results of reinoculation on a petridish B (border zone) and C (zone Trichoderma) colonies, that T. harzianum and T. virens regrew, while the pathogens were not able to regrow. When cohabiting with Sclerotium sp and Rhigidoporus sp, antagonistic fungus regrew after reisolation but pathogens also grew on Petridis B (border zone). It indicates that on the contact area (petri dish B), Sclerotium sp and Rhigidoporus sp conduct defense over the competition. Regrowth of fungal pathogens on contact area (border) indicates that the fungus has a high level of competition. Antagonist agents such as T. virens and T. harzianum were able to survive and regrow after cohabiting with fungal pathogens and showed type A interaction (against Fusarium sp), while cohabiting with Sclerotium sp and Rhigidoporus sp showed the type B interaction.

Abstract

The objectives of this research were to determine phosphorous nutrient tissue, yield, and quality of mangosteen in diverse of phosphorous doses. The experiment was arranged in a randomized complete block design.  Phosphorous doses evaluated were 0, 300, 600, 900, and 1200 g P/plant. The result showed that phosphorous fertilization increased of concentration mangosteen phosphorous tissue and yield per plant. However, phosphorous did not increase growth and fruits quality of mangosteen.
