Abstract

Arable land-use conversion into activities of non-agricultural production may encourage the use of wet region for soybean production. In this respect, a research on the adaptability of 25 soybean varieties to saturated soil has been conducted in the field. A randomized complete block design with 3 replicates was used in this experiment. Results of the experiment showed the adaptability differences among the 25 soybean varieties tested. Based on their yield, soybean adaptability to saturated soil condition was not related to plant growth type, but could be influenced by plant age. With an exception for Tidar (a high yielding variety belonging to the intermediate age), the late varieties produced highe  yield than that of the intermediate ones. It was concluded that the varieties belonging to high yielding ones were  characterized by the existence of positive correlation of pod number with nodule number and relative growth rate and of nodule number with relative growth rate and leaves area index. Key words: Soybean, Adaptation, Saturated soil, Agronomic traits

Abstract

Glasshouse experiment was conducted to study the effect of mycorrhizae inoculation and it's interaction with P supply on P leaf content and quality of oil palm seedling. Factorial experiment was arranged in Randomized Block Design with three replications. The first factor were mycorrhizae inoculation : without inoculation, mixed mycorrhizae, Acaulospora sp, Glomus manihotis, Glomus sp.1, Glomus sp. 2, Glomus sp. 3, The second factor were level of Roch Phosphate fertilizer : 0 g/seedling, 2 g/seedling, 4 g/seedling and 6 g/seedling. Mycorrhizae inoculation affected the P leaf content and percentage of infection significantly, Glomus sp decreased P leaf content. Acaulospora sp. gave the best quality of seedling, but Glomus sp. 3 gave the bad one. The Rock Phosphate application did not affect on P leaf content absorption efficiency and inoculation percentage due to high soil phosphorus content.

Abstract

Amount of water that obtained soil depend on soil ability to quick absorp and continue water accepted from soil surface. Water holding capacity of soil are influenced by soil texture and organic matter. The purpose of th is research was to study soil water holding capacity on two textures of soils l.e. clay, and clay loam by organic matter application of chicken manure and compost. Those treatments were control, combined of chicken manure different texture soils, and combined of compost different texture soil. Chicken manure and compost application consisted of two levels of 30 9 5 kg-l soil texture and 50 9 5 kg-l soil texture, respectively. Soil texture consisted of two kinds l.e, clay, and clay loam. The research was analyzed according to descriftive method. Result of this research indicated that the highest available water capacity of 17.352 % was given by combined t reatment of 50 9 compost of 5 kg clay textured soils. The lowest evaporation rate had occur at clay texture soils.
