Abstract

The purpose of this research is to know the effect of moisture content of field capacity on the growth of several mutant genotypes of 3rd generation (M3) Kipas Merah soybean varieties. The research was conducted at Screen House and Soil Chemistry Laboratory  Faculty of Agriculture Syiah Kuala Universtity from May to Jun 2015. The experimental Randomized Block Design (CRBD) factorial was used, consisting of two factors and three replications. The first factor was based on the field capacity level, consisting of 100%, 80%, 60%, and 40%, and the second factor consisted of 14 mutants of 3rd generation Kipas Merah and the original Kipas Merah variety as control. The results showed that the interaction between field capacity and soybean genotype significantly affected the growth of soybean crops. In a 40% field capacity treatment of almost all the parameters tested the genotype showed no significant difference, howeverKM300-38 showed the highest plant among the genotypes tested. In a 60% of field capacity, genotype KM200-18 and KM200-37 showed better growth on all parameters tested, although not significantly different from genotype KM200-9, KM200-41, and KM300-9. Genotypes of mutant soybean that can survive and provide good growth in water shortage are KM200-18, KM200-37, KM200-9, KM300-9, and KM200-41.Selection of drought-tolerant genotypes can be performed under 40% of the field capacity.

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

Selection of 3rd generation soybean mutants (M3) of Kipas Putih has been selected for tolerance of drought stress. The research was conducted at the Tissue Culture Laboratory of Faculty of Agriculture, Syiah Kuala University, Darussalam - Banda Aceh. Gamma ray irradiation was performed at Puslitbang Teknologi Isotop dan Radiasi BATAN, Pasar Jumat Jakarta. Seed of Varietas Wilis and Dering soy bean was used as control for drought tolerant and Kipas Putih was used as original variety. Selection was performed in vitro by using 20% Polyethylene Glycol (PEG). The results showed there were 8 genotype mutants categorized as tolerant to drought stress, ie KP100-26, KP100-28, KP200-31A, KP200-38, KP200-51, KP200-62, KP300-34, and KP300-47. Eleven mutan genotypes were categorized as medium tolerant and six genotypes were sensitive to drought. Selection of M4 generation selected lines are needed to find the drought tolerant and high-yielding mutant.
