Synthesis of new bimetallic phosphate (Al/Ag3PO4) and study for its Catalytic performance in the synthesis of 1,2-dihydro-l-phenyl-3H-naphth [1,2-e]-[1,3] oxazin-3-one derivatives

<p>This work aims to prepare a new bimetallic phosphate catalyst using a new simple and effective method. This new catalyst was ready for the first time by a modification of Triple Super Phosphate (TSP) fertilizer with silver sulfate (AgSO₄), followed by the impregnation of the aluminum atoms using aluminum nitrate (Al(NO₃)₃). The use of Al/Ag₃PO₄, for the first time as a heterogeneous catalyst in organic chemistry, offers a new, efficient, and green pathway for synthesizing 1,2-dihydro-l-phenyl-3H-naphth[1,2-e]-[1,3]oxazin-3-one derivatives by one-pot three-component cyclocondensation of b-naphthol, aryl aldehyde, and urea. The structure and the morphology of the prepared catalyst were characterized by spectroscopic methods such as X-Ray Diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR), and dispersive X-ray spectrometry coupled with a scanning electron microscope (EDX-SEM). In addition, the optimization of the reaction parameters was carried out considering the effect of catalyst amount, the temperature, and the solvent. The procedure described herein allowed a comfortable preparation of oxazine derivatives with excellent yields, short reaction times, and in the absence of organic solvent.</p>

Perlakuan terbaik dijumpai pada perlakuan pupuk TSP dengan dosis 1,20 g/tanaman (T2).

EFFECT OF DIFFERENT TYPES OF FERTILIZER ON THE GROWTH OF MARINE PHYTOPLANKTON POPULATION Chlorella vulgaris

This research was conducted on October 13-26, 2019 in the Regional Technical Implementation Unit of the Seawater and Brackish Aquaculture Fisheries Office (UPTD BPBALP Teluk Buo), West Sumatra. This study aims to determine the effect of applying different types of fertilizers to the growth of Chlorella vulgaris microalgae populations on laboratory scale culture. The method used in this study was an experimental method in the laboratory using a completely randomized design (CRD) one factor, namely the difference in fertilizer types with 3 (three) replications. Fertilizers used are Walne fertilizer, ZA (Zwavelzure Ammoniak) and TSP (Triple Super Phosphate). The testing organism in this study was phytoplankton C. vulgaris. The container used was a glass jar (3 liter capacity). The parameters measured in this study include absolute growth, relative growth, specific growth, self-doubling time and water quality. The results of this study indicate that the best type of fertilizer for C.vulgaris population growth was TSP fertilizer, followed by ZA fertilizer and the lowest in Walne fertilizer.

Farklı Dozlarda Fosfor Uygulamasının Şeker pancarı (Beta Vulgaris L.) Bitkisinin Verimine ve Besin Elementleri Alımına Etkisi

In this study, the effect of different phosphorus doses application on the yield and nutrient uptake of sugar beet plant was investigated under field condition. The study was carried out in Sivas province in 3 replications according to the randomized plot design and Valentina was used as the sugar beet variety. Phosphorus doses were; 0 kg P da-1, 15 kg P da-1, 30 kg P da-1 and applied as triple super phosphate (TSP). Leaf samples were taken approximately 80 days after the planting of sugar beet plant, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) concentrations and yield were determined at harvest. Research results indicated that the yield increased depending on the increasing phosphorus doses and the highest yield was obtained at 30 kg P da-1 dose with 8151.0 kg da-1. In addition, the highest nitrogen, phosphorus and potassium concentrations were found at 30 kg P da-1 dose (4.77% N, 0.74% P and 2.39% K, respectively). However, the research found that calcium and magnesium concentrations decreased with increasing phosphorus doses. While only iron concentration among microelements increased with phosphorus applications, zinc, manganese and copper concentrations decreased due to increasing phosphorus doses.

Status of Aqua Drugs Applied in Freshwater Aquaculture of Moulvibazar District, Bangladesh

Aims: Our study aimed to assess the current situation of accessibility and the use of various chemicals and medicines in freshwater aquaculture. Methodology: A questionnaire interview survey was conducted among 14 aquaculture farms and 23 aqua chemical retailers. Results: Due to easy availability, farmers used large quantities of lime and cow dung to prepare ponds and manage water quality. Beside these rotenone, zeolite gold, acme’s zeolite, aqua kleen, urea and TSP (triple super phosphate) are also found. Timsen, polgard-plus, deltix, virex, magic-fos and pond-safe were mostly used as a disinfectant. Epizootic Ulcerative Syndrome (EUS) disease was found predominantly in the farmer's pond. For disease treatment, renamycine soluble powder (oxy tetracycline) was used, 32% farmers. Two oxygen suppliers oxy gold and oxy life were used to increase oxygen concentration. Among 11 types of growth promoters were found in chemical shops in which charger gel and rapid grow were mostly used. Most farmers use gas trap and gasonex plus as gas reducer. Conclusions: There are mostly six categories of 48 aqua drugs and chemicals are observed and treated for health monitoring of fish and shellfish. Due to lack of knowledge concerning the proper dosage and procedure of using chemicals, technique of application and indiscriminate practice of chemicals etc. are common problems of aqua drugs in Moulvibazar district.

The Growth Rate Of Branchionus Plicatilis O.F. Muller Population With The Addition Of A Mixture Of Yeast, Chicken Manure Fertilizer, Urea, And Triple Super Phosphate (CAKAP)

The study of the growth rate of Branchionus plicatilis O.F. Muller population with the addition of a mixture of yeast, chicken manure fertilizer, urea, and triple super phosphate (CAKAP) was conducted in June 2012. Four treatments namely MK, MP1, Mp2, and MP3 were used in this experiment. MP1 consisted of CAKAP medium, 0.3 g/2L of yeast; MP1 consisted of CAKAP medium, 0.3 g/2L of yeast, and 0.1 ml/2L of fish oil. MP2 and MP3 have the composition as MP1 but show different concentrations of fish oil which were 0.2 and 0.3 ml/2L each. Every treatment had six replicates. The result showed that the highest growth rate of Branchionusplicatilis O F Muller was obtained from the first observation (day 2) of MP2 medium with the rate 2.605 individual x 2 x 10-3 per day while the lowest one was shown by MP3 medium which was 2.282 individual x 2 x 10-3 per day.

Fertilizer doses for jute cultivation after onion harvest

An experiment was conducted to evaluate the fertilizer dose for jute cultivation at the field after harvesting of onion at Gangabordi and Talma, Faridpur during 2017 with five treatments with different level of Urea, Triple Super Phosphate, Muriate of Potash and Gypsum. The result revealed that the treatment of higher doses of fertilizer gave the statistically significant highest fibre (2.76t/ha) yield whereas treatment of lower doses of fertilizer gave the lowest fibre yield (2.40 t/ha) but the Benefit Cost ratio from different treatment showed statistical non significance. From the view of economic profitability, farmers may use no fertilizer at their field during jute cultivation where previous crop was onion.
