Densification of ashy biochar into tablet can enhance the handling and conveyance efficiencies of biochar. It was hypothesized that fertilizer-embedded biochar tablets can slowly release embedded nutrients in synchrony with optimum nutrient uptake by crops. The objectives of this research were to determine the effects of biochar tablets with and without embedded fertilizer on soil chemical properties and nutrient use efficiency of Zea mays (sweet corn). The biochar tablet (BT) was produced by blending a biochar mixture with starch followed by densification using a single punch tablet press whereas the fertilizer embedded biochar tablet (BF) was prepared using the same procedure except that NPK fertilizer was added during blending. A pot experiment with five fertilization treatments including control was carried out in an open field located in Perlis, Malaysia. Co-application of biochar and fertilizer increased soil total carbon, nitrogen, but it reduced soil electrical conductivity (EC). Additionally, the BF significantly increased leaf chlorophyll content, dry root weight, and total plant nutrient use efficiency of sweet corn. The findings suggest that BF can serve as a slow release fertilizer to improve crop nutrient use efficiency. Therefore, embedding fertilizer in biochar tablets is recommended for sweet corn production following a long term field study to confirm the findings of this pot study.

Burning pineapple residues on peat soils before pineapple replanting raises concerns on hazards of peat fires. A study was conducted to determine whether ash produced from pineapple residues could be used to minimize carbon dioxide (CO2) and nitrous oxide (N2O) emissions in cultivated tropical peatlands. The effects of pineapple residue ash fertilization on CO2 and N2O emissions from a peat soil grown with pineapple were determined using closed chamber method with the following treatments: (i) 25, 50, 70, and 100% of the suggested rate of pineapple residue ash + NPK fertilizer, (ii) NPK fertilizer, and (iii) peat soil only. Soils treated with pineapple residue ash (25%) decreased CO2 and N2O emissions relative to soils without ash due to adsorption of organic compounds, ammonium, and nitrate ions onto the charged surface of ash through hydrogen bonding. The ability of the ash to maintain higher soil pH during pineapple growth primarily contributed to low CO2 and N2O emissions. Co-application of pineapple residue ash and compound NPK fertilizer also improves soil ammonium and nitrate availability, and fruit quality of pineapples. Compound NPK fertilizers can be amended with pineapple residue ash to minimize CO2 and N2O emissions without reducing peat soil and pineapple productivity.

At present, there is little information on the effects of organic amendments on black pepper farms particularly in Sarawak, Malaysia. The objective was to study the effects of organic amendments on selected soil properties, morphological characteristics, and yield of immature vines and its economic viability on immature pepper productions. There were five treatments each replicated five times in a randomized complete block design. Treatments were (i) F0—NPK 15:15:15 compound fertilizers, (ii) F1—fermented plant juice (FPJ), (iii) F2—FPJ incorporated with biochar, and compost, (iv) F3—fermented fruit juice (FFJ), and (v) F4—FFJ incorporated with biochar, and compost. The soil organic amendments which were consisted of fermented juices, biochar, and compost have positively improved soil bulk density, soil porosity, pH, CEC, TOC, C/N ratio, available P, exchangeable Ca, soil respiration, and soil microorganism count (bacteria, actinomycetes, and fungi). The fermented juices only or fermented juices with biochar and compost had lower effect on LAI and fruit spike length. The effect of soil organic amendments on fresh berry yield was comparable to that of NPK fertilizer. The economic viability study showed that the organic approach was comparable to the conventional NPK fertilization program. Through the interaction of beneficial microorganisms, biochar, and compost, introducing organic amendments in immature pepper cultivation is a reasonable option due to its contribution to yield that can lead to income sustainability for farmers.

A total of 30 bacterial isolates were isolated from soil, rhizoplane, and internal tissue of oil palm roots. The isolates were qualitatively tested for their potential to fix N2, solubilize inorganic P and K, and produce phytohormone indole-3-acetic acid. Of the 30 isolates, six isolates were able to exhibit multiple beneficial traits. All six isolates were then identified based on fatty acid methyl esters profile as Escherichia coli strain EX2, Serratia sp. strain EN1, Pantoea ananatis strain EN3, Bacillus sp. strain EN5, Pantoea ananatis strain EN8 and Pantoea sp. strain EN9. Subsequently, all shortlisted isolates were evaluated for plant growth-promoting potential by using shallot as a test plant. The plant test showed no significant difference (p>0.05) between inoculated and uninoculated plants except for Pantoea sp. strain EN9 inoculation which increased significantly (p

Serum biochemical parameters data was evaluated in broilers fed diets supplemented with hempedu bumi (Andrographis paniculata, AP) ground leaf. Birds (n = 160) were assigned in four treatment groups with five replication and each group contain eight birds. Broilers in the control group were fed the basal diet without additives, the group dietary treatments, Diet AP2 (Basal diet + 2g/kg Andrographis paniculata); Diet AP4 (Basal diet + 4g/kg Andrographis paniculata) and Diet AP8 (Basal diet + 8g/kg Andrographis paniculata). During day-21 and day-42, five birds from each treatment groups were randomly selected for serum biochemical analysis which involve pancreatic, renal, and hepatic functions (aspartate transaminase (AST), alkaline transaminase (ALT), alkaline phosphatase (ALP), glucose, cholesterol, triglycerides, total protein, albumin, urea, sodium, potassium, chlorine, and globulins). Liver morphology was determined after slaughtering two birds and collected the liver samples. Based on these results AP at 8g/kg diet lowered serum cholesterol, glucose and triglycerides. It also maintain the normal structure of liver indicating that no toxic effect from AP supplementation at a rate up to 8 g/kg, it also that AP lowered ALP and ALT in blood of chicken. In conclusion, supplementation of AP at 8g/kg in diet its beneficial effects on health and safe for broiler chicken production.
