    Effect of zinc and iron interaction on their distribution was examined in two wheat genotypes (UP262 and UP2628) under foliar application of 0, 0.25 and 0.50% ZnSO4 solution tagged with 925 KBq of Zn65 pot-1 for Zn and 0, 0.5 and 1.0% FeSO4 solution tagged with 925 KBq of Fe59 pot-1 for Fe at 30, 60 and 90 days after planting. Maximum grain yield of UP2628 (2.7 g pot-1 ) was recorded at 0.5%ZnSO4+0%FeSO4 while that of UP262 (2.63 g pot-1 ) was recorded at 0.5%ZnSO4+1.0%FeSO4. The highest straw yield of UP2628 (2.75 g pot-1 ) was noted at 0.5% ZnSO4+1.0%FeSO4 while that of UP262 (2.91 g pot-1 ) with 0.5%ZnSO4+0.5%FeSO4. Application of 0.5% and 1.0% FeSO4 reduced the accumulation of 65Zn in all parts of both the varieties. Regarding the 59Fe accumulation, it was found to be decreased with the increased application of ZnSO4 solution from 0.25% and 0.5% as compared to without application of Zn. On comparing translocation efficiencies of both the varieties, UP2628 showed better translocation thus accumulated higher zinc and iron. Therefore, variety UP2628 can be used further for crop improvement programme

    Physiological evaluation of nitrogen use efficiency and yield attributes in rice (Oryza sativa L.) genotypes under different nitrogen levels

    Nitrogen use efficiency, more specifically physiological nitrogen use efficiency depends primarily on management of N, one of the major essential nutrients. It is required in increased agricultural production and may possibly cause soil toxicity if fed in excess. Rate of N fertilizer application in fertile agricultural field and improved productivity in sterile soils require the improvement of NUE. A field experiment was therefore conducted to evaluate the effect of different N levels (N0, N50, N100 and N200) on rice genotypes. Vegetative plant growth was found to be reduced under N0 while improved at N200 level. Among the genotypes, highest PNUE (34.94) and correspondingly higher yield (7.15 ton ha−1) was observed for Krishna Hamsa. The other traits viz. plant height, no. of productive tillers and LAI exhibited higher values for Krishna Hamsa as well. Hence these can be utilized as physiological markers for the selection of rice genotypes efficient in N use

    In 1900, less than 20 percent of the world populace lived in cities, in 2007, fair more than 50 percent of the world populace lived in cities. In 2050, it has been anticipated that more than 70 percent of the worldwide population (about 6.4 billion individuals) will be city tenants. There's more weight being set on cities through this increment in population [1]. With approach of keen cities, data and communication technology is progressively transforming the way city regions and city inhabitants organize and work in reaction to urban development. In this paper, we create a nonspecific plot for navigating a route throughout city A asked route is given by utilizing combination of A* Algorithm and Haversine equation. Haversine Equation gives least distance between any two focuses on spherical body by utilizing latitude and longitude. This least distance is at that point given to A* calculation to calculate minimum distance. The method for identifying the shortest path is specify in this paper

    Ascorbic acid Beta-Carotene and Amino acids in Capsicum (Capsicum annuum) during fruit development in Himalayan Hills

    Capsicum varieties viz HC-201 & HC-202 developed at ARU, Almora took 35 days from fruit set to ripening. Results showed significant positive correlation for ascorbic acid and Beta-carotene with days to maturity. Out of eight ninhydrin positive products, only seven could be identified viz, hydroxyproline, proline, lysine, 5-alanine, arginine, threonine and methionine, at the later stages of the fruit development. All amino acids except methionine were found either absent or in traces at the earlier stages of fruit development

    Enhancing zinc bio-fortification in wheat through agronomic interventions

    Around half of the world’s agricultural soils, including sandy loam soils of Punjab region, are deficient in zinc (Zn), leading to decreased crop production and nutritional value. Balanced application of macro nutrients along with Zn bio-fortification enhances crop productivity and reduces the deterioration of soil health. This study investigates the effect of zinc sulphate monohydrate (ZnSO4.H2O) on growth, yield and nutrient uptake of wheat (Var. PBW-343). The plants were subjected to the following treatments: T1 (control), T2 (100% recycling-derived fertilizers, RDF), T3 (100% RDF + 5 kg ZnSO4.H2O ha-1), T4 (100% RDF + 10 kg ZnSO4.H2O ha-1), T5 (100% RDF + 15 kg ZnSO4.H2O ha-1), T6 (100% RDF + 20 kg ZnSO4.H2O ha-1) and T7 (100% RDF + two spray of ZnSO4.H2O @ 0.5% at tillering and late jointing stages). The results revealed that the plant height, number of functional leaves per plant, number of tillers per plant, number of effective tillers per plant, spike length, number of grains per spike, test weight, grain yield and straw yield are significant and found maximum in treatment T5; which was 100% RDF and 15 kg ZnSO4.H2O ha-1

    Single quantum emitters play a fundamental role in the development of quantum technologies such as quantum repeaters, and quantum information processing. Isolating individual molecules with stable optical emission is an essential step for these applications, specially for those molecules that present large coherence times at room temperature. Among them, vanadium-oxide phthalocyanine (VOPc) molecules stand out as promising candidates due to their large coherence times measured in ensemble. However, the optical properties of individual molecules have not yet been reported. Here we show that single VOPc molecules with stable optical properties at room temperature can be isolated. We find that the optical response of the molecule under laser illumination of different polarization agrees well with a system having pyramidal C4v_{4v} symmetry. Furthermore, the molecule reveals a non-radiative transition rate that depends on the excitation wavelength when its lifetime is interrogated. We provide theoretical calculations that support our experimental findings and provide insight to the role of phonons and internal electronic structure of the molecule. These results demonstrate that this single paramagnetic molecule can function as a single quantum emitter while displaying optical stability under ambient conditions to have their intrinsic properties investigated

    Seed spices are an important category of agricultural commodities that contribute significantly to our country's economy. India has long been known as a spiceproducing country. Coriander, cumin, and fennel are members of the umbelliferon family, whereas fenugreek belongs to the Fabaceae family. Bioactive compounds, also bioactive constituents, are occurs naturally, physiologically active phytochemicals that operate as a natural defence mechanism for host plants or have previously been exploited as medications, perfumes, or taste components. They're a gold mine of opportunities in our search for useful bioactive molecules for pharmacotherapy or other wellness issues. Seed spices affect a number of biological systems, such as the digestive, circulatory, reproductive, or neurological systems, causing a range of metabolic but also physiologic consequences. Antioxidants, antidiabetic, anticancer, antimicrobial activity, hypolipidemic influence, insecticidal, beneficial in heavy menstrual bleeding, aiding digestion, high blood pressure, instrumentation of enzymes involved, immune function, reduction of inflammatory process, molecular mechanism, modulations of immune systems, The purpose of this research is to have a thorough analysis on the present trends in research here on health advantages of four common seed seasonings: cumin, coriander, but also fennel.</jats:p
