Synthesis and Characterization of a Mixed Nanofertilizer Influencing the Nutrient Use Efficiency, Productivity, and Nutritive Value of Tomato Fruits.

Abstract: Due to the higher potential for enhancing nutrient use efficiency, nanofertilizer (NF) is crucial in sustainable crop production. Thus, foliar-applied mixed nanofertilizer (MNFf) and commercial fertilizer (CF) into the soil (CFs) were claimed together ([MNFf + CFs]) and comparative nutrient use efficiency (NUE), productivity, and nutritional properties of tomato fruits were investigated. The mixed nanofertilizer (MNF) was prepared in our laboratory and characterized using scanning electron microscopy, X-ray diffraction, and Fourier transform infrared. To avoid the interference of other factors, all the treatments were divided into three groups: (i) blank treatment (no fertilizer), (ii) CF treatment, and (iii) combined [MNFf + CFs] treatment. The vegetative growth and qualitative and quantitative attributes of tomatoes were recorded, and the NUE, total production, and benefit-cost ratio (BCR) were also calculated. In addition, comparative nutritional properties for all treatments were analyzed. The plant's height, stem diameter, root length, photosynthetic pigments, leaf minerals, and qualitative traits of tomato fruits were significantly (p < 0.05) increased by [MNFf + CFs] treatment compared to CFs. The protein, fiber, Fe, Zn, and K contents were significantly (p < 0.05) increased by 23.80, 38.10, 44.23, 60.01, and 2.39%, respectively, with the [MNFf + CFs] treatment as compared to CFs, while the ash and protein contents were both lower than the untreated tomato. Moreover, [MNFf + CFs] treatment has significantly (p < 0.05) increased the antioxidant properties. The NUE, total production, and BCR were also increased by 26.08, 26.04, and 25.38%, respectively, with the same treatment. Thus, [MNFf + CFs] treatment could be a potential alternative for reducing the excess use of CF.

Catalytic SO3 Decomposition Activity of SiO2-Supported Alkaline Earth Vanadates for Solar Thermochemical Water Splitting Cycles

Abstract: Alkaline earth vanadates (Ae–V: Ae = Ca, Sr, and Ba) were supported on mesoporous SiO2 by a wet impregnation method. The catalytic activity of the prepared materials for the decomposition of SO3 in...

Removal of dark blue-GL from wastewater using water hyacinth: a study of equilibrium adsorption isotherm

Abstract: The present investigation demonstrates that water hyacinth root is a potential adsorbent for the removal of dark blue-GL dye from wastewater by batch process. Various operating parameters such as the adsorption capacity, initial dye concentration, contact time, effect of pH, and adsorbent dosage were examined at different experimental conditions. The effect of pH and dye concentration found to be crucial, have been optimized, and the maximum recovery (~90%) was detected at pH 3 and concentration 150 ppm. The separation of dark blue-GL is proportionally related to the adsorbent dosage, and up to 77% dye was recovered for the dose 1.5 g/L. Langmuir adsorption isotherm model of the adsorption process was carried out at the equilibrium concentration of dark blue-GL uptake, and the corresponding data were analyzed by the least square methods. Kinetic parameters calculated from the tentative data could be fitted well to a pseudo-second-order kinetic model. These results point out aptness of the adsorben...

Free radical-scavenging capacity and HPLC-DAD screening of phenolic compounds from pulp and seed of Syzygium claviflorum fruit

Abstract: Recently, the demand for natural antioxidants in food manufacturing has increased significantly because of the possible toxicity of synthetic antioxidants. In this context, this research work was performed to evaluate the potentiality of seed (seed with kernel) and pulp (edible portion: pulp with peel) of Syzygium claviflorum to serve as natural antioxidants. The free radical scavenging capacity of S. claviflorum extracts was evaluated by 2,2′-azino-bis (3-ethylbenzothiazolin)-6-sulfonic acid (ABTS), and 1,1-Diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assays. In DPPH and ABTS free radical scavenging assays seed extract demonstrated significantly (p

Fry production and its marketing system of North-West fisheries extension project at Parbatipur, Dinajpur, Bangladesh

Abstract: In order to understand the present status of hatcheries, questionnaire interview and participatory rural appraisal tools were used in North-west Fisheries Extension Project (NFEP), Parbatipur during the period from July to December 2015. There are two hatcheries in NFEP, Parbatipur- a carp hatchery and a prawn hatchery. The production of spawn was around 611 kg in the year 2015. According to the target hatchery manager collected brood fish from rivers and other sources which he maintained in their brood stock ponds with proper management. The hatchery manager maintained proper age and weight of broods for spawning and followed the guideline of hatchery operation so that the quality of spawn and fry were good. It was found that the hatcheries produced fish seed of a variety of species such as Indian major carps, carpio, sarpunti, silver carp, grass carp, magur, shing as well as freshwater prawn. The hatchery production activities took place starting from February and continued up to September. The quantity of fish seed produce varied from 25 to 75 kg per hatching cycle depending on size and facilities of hatcheries. The price of fry in NFEP was being fixed by the hatchery manager. However, the price variation was seen due to seasonal variation, species and demand. The average price of fish seed was highest in monsoon and lowest in winter. A number of middlemen were involved in the fry marketing channel of NFEP at Parbatipur. They were responsible for increasing the price of fry at each stage of marketing channel. Asian J. Med. Biol.
