Modified plant architecture integrated with liquid fertilizers improves fruit productivity and quality of tomato in North West Himalaya, India.

India produces around 19.0 million tonnes of tomatoes annually, which is insufficient to meet the ever-increasing demand. A big gap of tomato productivity (72.14 t ha-1) between India (24.66 t ha-1) and the USA (96.8 t ha-1) exist, which can be bridged by integrating trellis system of shoot training, shoot pruning, liquid fertilizers, farmyard manure, and mulching technologies. Therefore, the present experiment was conducted on tomato (cv. Himsona) during 2019-2020 at farmers' fields to improve tomato productivity and quality. There were five treatments laid in a randomized block design (RBD) with three replications; T1 [Farmer practice on the flatbed with RDF @ N120:P60:K60 + FYM @6.0 t ha-1 without mulch], T2 [T1 + Polythene mulch (50 microns)], T3 [Tomato plants grown on the raised bed with polythene mulch + FYM @ 8.0 t ha-1 + Single shoot trellis system + Side shoot pruning + Liquid Fertilizer (LF1-N19:P19:K19) @ 2.0 g l-1 for vegetative growth + Liquid Fertilizer (LF2-N0: P52: K34) @ 1.5 g l-1 for improving fruit quality], T4 [Tomato plants grown on the raised bed with polythene mulch + FYM @ 8.0 t ha-1 + Single shoot trellis system + Side shoot pruning + LF1 @ 4.0 g l-1 + LF2 @ 3.0 g l-1], and T5 [Tomato plants grown on the raised bed with polythene mulch + FYM @ 10.0 t ha-1 + Single shoot trellis system + Side shoot pruning + LF1 @ 6.0 g l-1 + LF2 @ 4.5 g l-1]. The results revealed that tomato plant grown on the raised beds with polythene mulch, shoot pruning, trellising, liquid fertilizers, and farmyard manure (i.e., T5) recorded higher shoot length, dry matter content, and tomato productivity by 20.75-141.21, 18.79-169.4, and 18.89-160.87% as compared to T4-T1 treatments, respectively. The T5 treatment also recorded the highest water productivity (28.39 kg m-3), improved fruit qualities, net return (10,751 USD ha-1), benefit-cost ratio (3.08), microbial population, and enzymatic activities as compared to other treatments. The ranking and hierarchical clustering of treatments confirmed the superiority of the T5 treatment over all other treatments.

Synthesis and characterization of cluster of grapes like pure and Zinc-doped CuO nanoparticles by sol-gel method.

Pure CuO and Zn-doped CuO nanoparticles were synthesized from sol-gel process by reacting copper acetate monohydrate with a urea in distilled water at 80°C. The synthesized Samples were different concentrations but same annealing temperature at 400°C. The obtained samples were characterized by means of UV-visible spectroscopy (UV-vis), X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), Field emission scanning electron microscopy (FE-SEM) and Energy dispersive X-ray spectroscopy (EDS). UV-visible technique used to measure the band gap of the synthesized samples. The XRD spectra of the synthesized samples confirmed the CuO nanoparticles with monoclinic structure. All the functional groups of the pure and doped synthesized samples were investigated by FT-IR analysis. The morphological and elemental estimation of the pure and Zn-doped synthesized samples were examined by FE-SEM with EDS.

Bradycardia and severe vasospasm caused by intramyometrial injection of vasopressin during myomectomy.

Vasopressin is often used locally to reduce blood loss during surgery. Vasopressin has longest clinical effect, but its systemic effects may be profound and pose significant challenges for the anesthesiologist and it can also sometimes cause lethal complications. The loss of peripheral pulse along with bradycardia, non-measurable arterial blood pressure, and cardiac complications have been reported after myometrial injection of vasopressin. Here, we describe a patient with multiple uterine myomas who developed severe bradycardia, non-measurable blood pressure by non-invasive means and loss of peripheral pulse after myometrial injection of vasopressin at a total dose of 20 units (1 unit/ml) with documentation of severe peripheral arterial vasospasm and increased proximal blood pressure. The patient was successfully resuscitated.

Surface modifications of CuO nanoparticles using Ethylene diamine tetra acetic acid as a capping agent by sol-gel routine.

The uncapped and capped CuO nanoparticles were synthesized by sol-gel process. Ethylene diamine tetra acetic acid (EDTA) used as a capping agent to control the size and morphology of the CuO nanoparticles. Control the nanostructure and optical properties of CuO nanoparticles are deliberate by using capping agent. The obtained samples were characterized by means of UV-Visible spectroscopy (UV-Vis), X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM) along with energy dispersive X-ray spectroscopy (EDS). UV-Visible technique used to measure the band gap of the synthesized samples. The XRD spectra of the synthesized samples confirmed the CuO nanoparticles with monoclinic structure. The occurrences of capping agent have been analyzed by Fourier transform-infrared spectroscopy (FT-IR). The FT-IR study revealed that the transmittance peaks at 501cm(-1) and 592cm(-1) were CuO stretching mode, and 677cm(-1) was CuO monoclinic phase of the uncapped CuO nanoparticles. Further, SEM study find out the morphology of the synthesized samples, where the surface morphology changes occurred with an addition of capping agent. Moreover, the capping mechanism has been discussed based on the chemical reaction between the CuO nanoparticles and the functional groups of the capping agent.
