An incubation experiment was carried out to assess bone char application on the availability and distribution of phosphorus in agricultural alkaline sandy soils. Three alkaline agricultural sandy soils in Upper Egypt have been collected from Arab El-Awamer at Assiut governorate, West El-Minia at El-Minia governorate, and New Valley Governorate. 100 grams were taken from each soil under study and placed in a plastic jar. The bone char is applied at level 0.4 g jar-1 into these soils. This experiment was incubated at 23 ºC in the dark for periods of 7, 16, 35, 65, and 84 days and arranged in a completely randomized design with three replicates. The results revealed that bone char applications to the soils resulted in a significant positive increase in the availability of phosphorus affected by the soil type and incubation periods in Arab El-Awamer soil. The percentage of increase in available phosphorous after adding bone char compared to before incubation was as follows: Arab El-Awamer soil ˃New Valley soil ˃West El-Minia soil. The available phosphorous was negatively correlated with electrical conductivity (r=-0.288*), soluble calcium (r=-0.306*), and soluble sulfate (r=-0.413*). The concentrations of NH4Cl-Pi, NaHCO3-Pi, NaOH-Pi, HCl-Pi, residual-P fractions increased significantly in some soil types with applying bone char. The concentrations of available phosphorous in all soils under study were positively correlated with all phosphorus fractions. We conclude that bone char applications into P-poor soil are important to potentially enhance phosphorus availability. Bone char is considered a promising strategy in sustainable agriculture.

Upland soils in West Kalimantan used for agricultural activities reach about 483,077 hectares. However, this land potential is not yet optimally exploited due to poor soil fertility. To increase its productivity, there is a need to invent technology packages that are not only effective but also efficient. This research is designed to study the growth of upland rice and the changes in certain soil properties after low-input treatment applications. This research used a Completely Randomized Design. There were 6 treatments and 4 replications. The treatment levels were P0 (no treatment), P1 (7tons of cow manure/ha + 300 kg NPK compound), P2 (15tons of cow manure/ha + 300 kg NPK compound), P3 (7tons of compost/ha + 300 kg NPK compound), P4 (15tons of compost/ha + 300 kg NPK compound), and P5 (600 kg/ha NPK compound). Parameters included plant height and dry weight, NPK absorptions, soil pH, organic C content, and NPK contents after soil treatment. The results showed that upland rice responded well to low-input amendment treatments compared to that of grow-in soil with no input treatments. Both the treatments using 15 tons of cow manure and 15 tons of rice straw compost per hectare, each plus 300 kg of NPK, were suggested to be further research topics for treatments in upland soil of West Kalimantan.

The use of biostimulants in fish diets is a promising strategy to reduce the use of antibiotics, enhance the biochemical and immune response, which contributes to improving productive yields and reducing economic losses. The biochemical and immune response was evaluated in juvenile red tilapia (Oreochromis mossambicus × O. niloticus), with different levels: 0 (control), 1, 2, 3, 4 and 5% chitosan in diet. 270 animals (7.53 ± 0.50 g of initial weight), distributed in a completely randomized design of 6 treatments with 3 replicates and 45 tilapia.treatment-1, were sown in 18 tanks with 90 L of water in a closed system. The juveniles were fed for 55 days with the experimental diets and at the end of the bioassay the tissue and blood plasma samples were taken. Differences were found (p<0.05) in the variables evaluated responses, where the content of lipids, triglycerides, cholesterol, carbohydrates and glucose showed higher levels (p<0.05) at lower chitosan concentrations. However, for protein content, a better response (p<0.05) was found at higher levels of chitosan in the diet. Regarding dry matter and ash, no differences were found (p˃0.05). While superoxide dismutase and leukocytes were found in higher concentration (p<0.05) when supplemented with chitosan by 3 and 4%. It was concluded that the juvenile biochemical and immune response of red tilapia was favored with dietary chitosan supplementation.

Abstract: Xanthomanas campestris pv. oryzae is the causal agent of rice bacterial blight, a destructive rice disease worldwide, is increasing recently in Vietnam. Many people attempted to control this disease by chemical sprays. However, there are claims and counterclaims about the performance of many chemicals because they are hazardous to human health and environment. The most accepted and promising strategy is breeding resistant cultivars. In this study, 66 rice lines provided by IRRI were evaluated the resistance to bacterial leaf blight in Thua Thien Hue of Vietnam. The experiment was laid out in a completely randomized design (CRD) without replication in Spring-Summer 2015 in the open field at Quang Dien, Thua Thien Hue. The results showed that rice lines were high resistance against bacterial leaf blight. The IR 12 line performed the highest susceptant level to bacterial leaf blight. Based on agronomic traits and level of bacterial leaf blight resistance, IR 3, IR 4, IR 46, IR 28, IR 6, IR 18, IR 14 và IR 26 lines were selected for breeding program

This work aimed to characterize the biochar produced from residues of coconut fruit and to evaluate how it might beneficially alter the retention capacity of water and nutrients in soils with a sandy texture. The biochar was produced in a retort furnace and later analyzed to determine its chemical and physical characteristics. Experiments to analyze the retention potential of the biochar for water and nutrients were performed in PVC columns filled to a 400 mm depth, with the upper 300 mm receiving treatments that consisted of 0, 1, 2, 3, 4, and 5% (p p-1) biochar mixed with soil. For the nutrient retention experiment, in addition to the biochar concentrations, the treatments received the same NPK fertilization. The experiments were performed in a completely randomized design with four replications. The water retention in the upper 300 mm, as well as the pH, effective cation exchange capacity (ECEC) of the substrate, base saturation, and concentrations of P and K, increased with increasing biochar concentration. Coconut biochar demonstrated potential for increasing water retention and improving nutrient retention in sandy soils.

The availability of phosphorus in the soil is a factor that directly interferes with its absorption by plants. This availability can be influenced by the texture, dose of the phosphate fertilizer and the time of contact with the soil. This study aimed to quantify the organic and inorganic fractions of P accumulated in a sandy soil receiving doses of phosphorus, incubated and grown with rice. The experimental design was a completely randomized design, in a 4 &times; 3 factorial scheme, with four replicates, and four P doses (0, 80, 240, and 410 mg dm-3) and three evaluation times (before sowing, after harvest, and incubated). Soil samples were collected before, after incubation, and after rice harvesting, and then submitted to a chemical fractionation of P. P fractions were influenced by soil collection times. The inorganic fractions prevailed before sowing and after incubation, and the organic fractions prevailed after harvest. Phosphate fertilization favored mineralization of organic P and redistributes the inorganic and organic P fractions, between labile and non-labile compartments. The application of phosphate fertilizer in an Entisol Quartzipsamment contributes to the accumulation of inorganic fractions, especially in the most labile fractions.
