Experiments that compare the yield potential of reduced branching narrow-leafed lupins with that of the conventional branched types show that on sandy soils of low water-holding capacity in a short season environment, reduced-branching lupins have a higher yield potential than current cultivars. The yield potential of these new types appears to be maintained over a wide range of environmental yield levels. L. angustifolius was higher yielding than L. albus or L. cosentinii genotypes of similar maturity.

Water Holding

The productivity of sandy soils is mostly limited by their low water-holding capacity and excessive deep percolation losses, which reduce the efficiency of water and fertiliser use by plants. The effect of a crosslinked-type polyacrylamide, ALCOSORB 400, on water-holding capacity of a sandy soil, siliceous sands, was studied under the laboratory and glasshouse conditions. Water-holding capacity of the soil exposed to 0.01 MPa increased by 23 and 95% by adding 0.03 and 0.07% of polyacrylamide to the soil, respectively. This indicated that the soil treated with polyacrylamide was able to store more water than untreated soil, thereby reducing the potential losses due to deep percolation in sandy soils. However, the polyacrylamide in the treated soil did not significantly increase the quantity of water released from the soil by increasing the pressure from 0.01 to 1.5 MPa. The results from the first glasshouse experiment demonstrated that the excess amount of water stored in the soil by polyacrylamide was available to plants and resulted in higher water use and grain production. Consequently, there was a 12 and 18 fold increase in water use efficiency of soybean plants grown in soils treated with 0.03 and 0.07% polyacrylamide, respectively. The results from the second glasshouse experiment demonstrated that increasing amounts of polyacrylamides in a sandy soil can extend the irrigation interval without any adverse effect on the grain yield of soybeans.

Abstract Quantifying the manners in which biological activity may alter the hydraulic properties of soils (SWCCs) is vital for understanding and engineering water pollution and supply systems. The study used centrifugation and a sand funnel method to determine the SWCCs of pure sandy soils with different particle sizes and sandy soils mixed with different extracellular polymeric substance (EPS) analogs. Sensitivity of correlated parameters for SWCCs obtained using a van Genuchten (VG) model was analyzed by a single-factor perturbation analysis. The results show (1) that fine sand has the strongest water retention ability. (2) The more polysaccharide contents in the media, the stronger its water-holding capacity. Polysaccharide not only has its strong water holding capacity, but also changed the structure of medium to increase water holding capacity. The humic acid and protein components had little effect on the hydrodynamic properties of fine sandy soil. (3) Sensitivity analyses revealed that the saturated water content, θs, greatly affected the ability of solute transport to reach equilibrium concentrations. Therefore, it is very necessary to define the range of media particles and component content,and ensure the accuracy of VG model parameters in the practical application of soil media affected by biological activity.

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh penambahan minyak buah merah (MBM) pada pakan terhadap kualitas fisik daging ayam broiler. Seratus ekor ayam broiler umur sehari (DOC) ditempatkan pada lima kelompok perlakuan pakan yang berbeda, yaitu: P1 (pakan kontrol/tanpa penambahan minyak), P2 (2% MBM), P3 (4% MBM), P4 (6% MBM) dan P5 (6% Minyak kelapa sawit). Setiap kelompok perlakuan terdiri dari empat ulangan masing-masing dengan lima ekor. Ayam broiler dipelihara selama 35 hari. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan analisis variansi pola searah dan diuji lanjut dengan Duncan’s New Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa semua variable yang diamati menunjukkan adanya pengaruh nyata (P<0,05) terhadap perlakuan yang diberikan. Dari hasil penelitian ini dapat disimpulkan bahwa penggunaan minyak buah merah (MBM) dalam pakan mampu memberikan pengaruh terhadap pH Daging, Daya Ikat Air (DIA), susut masak dan keempukan daging ayam broiler.Kata kunci : daging ayam broiler, daya ikat air, keempukan daging, pH daging, susut masakABSTRACT The experiment was conducted to study the effect of red fruit oil (RFO) onphysical quality  of broiler chicken. One hundred day old chicken (DOC) were placed in four groups of different treatments, of from levels of RFO (P1 (diet without addition of RFO), P2 (2% RFO), P3 (4% RFO) and P4 (6% RFO) and P5 (6% Palm oil)). The treatment group consisted of fivereplications with five birds each. Broiler chickens were reared for 35 days. Statistical analysis used Completely Randomized Design (CRD) and followed by Duncan’s New Multiple Range Test (DMRT). The results showed that the pH value, moisture content, water holding capacity, and cooking loss was significant differences. It could be concluded that the addition of red fruit oil in the diet give effect  of broiler chicken meat.Keywords: broiler meat, cooking loss, moisture content, pH value, water holding capacity
