The present study, "Effect of plant growth regulators on growth, fruit setting, and quality of guava (Psidium guajava L.) in meadow orchard," was carried out in the years 2021–2022, at Central Research Farm, Department of Horticulture, Sam Higginbottom Institute of Agriculture & Sciences, Prayagraj (U.P.). Ten treatments made up the experiment with: control, three concentrations of gibberellic acid (GA3) at 75, 100, and 125 ppm, three concentrations of naphthalene acetic acid (NAA) at 200, 250, and 300 ppm, and three concentrations of chlormequat (CCC) at 400, 500, and 600 ppm. These treatments were evaluated in Randomized Blocked Design with three replications. The results showed that a combination of different plants growth regulators had a significant impact on the guava plant's growth and yield parameters, including its height (5.81 m), total number of flowers per plant (178.6), fruiting buds per plant (151.8), number of fruits per plant (127.1), fruit set (71.2%), plant spread (E-W-6.00 m & N-S- 5.89 m), fresh fruit weight (115.5g), and dry weight (78.5g), Fruit diameter (polar-8.46cm & radial-8.16cm), total soluble solids (TSS) 10.170Brix, total sugar (9.2%), and yield/plant (14.7kg) were all found to be higher under the treatment T4 Naphthalene acetic acid (NAA) @200ppm, whereas acidity (0.56%) was at its highest in T0 Control.

under RCBD (Randomized Complete Block Design) with four replications.The treatment combinations were Ambika paddy weeder at 20 and 40 day after transplanting, Bispyribac-sodium @ 80g ha -1 at 15 day after transplanting, hand weeding twice at 20 and 40 day after transplanting, water imponding of 40 days, 10 days after transplanting, no water imponding alongwith one control (no weeding).Plant height, LAI at 60 DAT, Tiller hill -1 , Panicle hill -1 , Penicle length (cm), Grains panicle -1 , CGR (g plant -1 day -1 ) at 60-90 DAT, RGR (g plant -1 day -1 ) at 60-90 DAT were recorded higher value in hand weeding twice @ 20 and 40 days after transplanting than remaining treatments except bispyribac-sodium @ 80 g ha -1 at 15 DAT which was at par to that of hand weeding twice.Maximum number of panicle hill -1 , panicle length, seeds panicle -1 , and test weight were recorded with hand weeding twice @ 20 and 40 days after transplanting which was significantly superior over rest of treatments, being on par to application of bispyribac-sodium @ 80 g ha -1 at 15 days after transplanting.Hand weeding twice at 20 and 40 days after transplanting produced significantly higher grain yield (42.79 q ha -1 ) than rest of treatments except application of bispyribac-sodium @ 80 g ha -1 at 15 days after transplanting (40.31 q ha -1 ) which were 40.94% and 32.77% increased in yield over control.Among the treatments, the highest quantity of CO2 emission from rice field was with hand weeding twice at 20 and 40 DAT (2465.31g day -1 ha -1 ) at 35 DAT and the lowest was recorded when applied bispyribacsodium @ 80 g ha -1 at 15 DAT (202.98 g day -1 ha -1 ) at 45 DAT, which was highest and lowest level of agronomical manipulations in respective treatments reflecting on emission.

Sixteen genotypes were tested the 2016-2017 seasons for their yield performance. In the examined characteristics, positive and significant relationships were found statistically between 100 seed weight and plant height, between the number of secondary branches and plant height, between day to heading and day to maturity, between day to maturity and number of primary and secondary branches, between seed yield and number of pod plants and number of seed pod, between seed yield and biomass and harvest index were determined significantly. Negative and significant relationships were determined statistically between number of pod plant and 100 seed weight, between seeds pod and number of secondary branches. Harvest index had the greatest direct effect on seed yield (p.c. =0.901**). Also, its indirect effect on seed yield more positive through plant high, number of pod plant, number of seeds pod and biomass, but negative and low through day to heading and maturity, 100 seed weight and number of primary branches. The present study thus suggested that selection for high seed yield should be based on biomass (biological yield) and harvest index in kabuli.

Microstructural and tribological characteristics of cold rolled spray cast Al-6Si-20Pb alloy were studied for different percentage of thickness reduction. The length of aluminum grains and the width of grain boundary were observed to increase with the increase in percentage of thickness reduction. Wear rate was found to decrease with the increase in percentage of thickness reduction for all the applied loads.

The universal current reversal method is used for the simultaneous measurement of response time (τ), azimuthal angle (ϕo), spontaneous polarization (P S), and rotational viscosity (γϕ) of two ferroelectric liquid crystals (FLCs). The application of AC field in FLCs results in reorientational current, which is further analyzed to obtain various parameters. The variation in the parameters with temperature follows the typical trend predicted by the theory. The theoretical curve fits well into the experimental data. Its comparison with traditional current reversal method is confirmed to address certain limitations of that method.

The conventional soybean oil hydrogenation process (metal catalyst on solid support particles slurried in oil, H(2) bubbled through the oil) is compared with metal-decorated integral-asymmetric polyetherimide (PEI) membranes, as far as changes in temperature and pressure are concerned. Using metal-decorated polymeric membranes, H(2) is supplied to the catalytic sites by permeation from the membrane substructure. As opposed to the slurry process, metal-decorated membranes show only slightly increased trans fatty acid (TFA) formation when the temperature is raised (50-90 degrees C) to accelerate the process. This is likely due to the efficient and to some extent self-regulating H(2) supply directly to the catalytic sites on the membrane skin. The hydrogenation rate and TFA formation of the metal-decorated membrane process show a minor dependence on pressure. (C) 2010 American Institute of Chemical Engineers AIChE J, 57: 2450-2457, 2011

The electrical properties of Hibiscus Sabdariffa grafted co-polymer reinforced phenol formaldehyde composite were studied with reference to dielectric constant, dielectric dissipation factor, dielectric loss factor and volume resistivity. The dielectric constant was found to decrease with frequency that was due to decrease of polarization. The dissipation factor showed first increase and then decrease with increase in frequency at different voltage. The volume resistivity of composite also decreased with frequency. The dielectric loss factor was observed to be high at lower frequency which was due to polarization of fiber at lower frequency.

Three phase reaction schemes pose numerous challenges to reactor design due to the slow diffusional mass transfer of reactants from the gas phase through a liquid to the active sites of the catalyst. An example is partial hydrogenation of vegetable oil which is traditionally carried out in a batch autoclave by bubbling hydrogen gas though a slurry of oil and solid catalyst particles containing Ni. Unwanted trans fatty acids (TFAs) are formed during this process due to the scarcity of hydrogen at the active catalyst sites. Here we investigate the use of metal-decorated integral-asymmetric polymer membranes to enable the supply of dissolved hydrogen near the location where the liquid oil phase contacts the catalyst. Hydrogen gas is supplied to the porous substructure of the asymmetric membrane where it dissolves in the thin skin layer of the membrane and emerges as dissolved hydrogen on the metal-decorated side of the membrane where the oil is present. Temperature and pressure are compatible with existing facilities. All membranes produced low TFA (2.6–4.6wt% at Iodine Value of 95) compared to the slurry process. A 1000 metric ton per day soybean oil hydrogenation facility would require 2–3000m2 membrane area with a total of 90g of Pt metal catalyst. This could be envisioned as metal sputtered hollow fibers packaged in conventional modules.

Partial hydrogenation of vegetable oils is carried out to improve the chemical stability and raise the melting point to produce semi-solid products such as margarine. Trans fatty acids formed during traditional hydrogenation have come under intense scrutiny with regard to human health. Here we report partial hydrogenation of soybean oil using a high performance integral-asymmetric polyetherimide membrane sputtered with platinum to deliver hydrogen directly to or near the catalytic sites. Oil flows past the platinum-coated “skin” side of the membrane while dissolved molecular and some atomic hydrogen is supplied from the highly porous substructure of the membrane. The membrane has a high hydrogen flux but is essentially impermeable to soybean oil. Hydrogenation using our metal/polymer catalytic composite membrane produced oil with only 4 wt.% total trans fatty acids and 14.5 wt.% C18:0 saturates at IV of 95 while the conventional Pt/C slurry reactor produced more than 10 wt.% TFA and the same amount of C18:0 saturates under similar conditions of temperature and pressure. Our concept requires hydrogen pressures of only about 65 psi and temperatures near 70 °C. The polymeric base membranes used here have been mass produced and can be packaged in spiral wound modules. The relatively mild reaction conditions and the direct pathway to produce useful membrane modules combine to make our concept promising for near-term application.

A parameter based on correlation coefficient between deviations of yields of a variety from corresponding mean yields recorded at several locations, and the estimates of similar deviations for a check variety was used to estimate response of each of the 44 varieties included in National Initial Varietal Trial - Irrigated Timely Sown, Coordinated Trial of bread wheat planted in North Western Plains Zone and North Eastern Plains Zone during 1999–2000. Five well established standard check varieties were also included in the trial for comparison. The deviations in the yields of test entries from mean yield of all the test entries and the checks were computed for each location. The correlations between deviations of the yields of a variety and those of each of the checks were treated as measures of sensitivity or response. Significant positive correlation was taken as a measure of similarity between a variety and a check included in the pair while recommending variety for promotion or identification. This response estimate of a variety can be used as an additional parameter along with yield potential and other desirable characteristics conventionally used. Only thirteen test entries exhibited similarity in response with the five check varieties used. In the given example two varieties HD 2790 and WH 736 should have been promoted to the next trial of higher order on being statistically identical in sensitivity with standard check varieties HD 2329 and HP 1731, respectively. The variety HD 2790 was also statistically at par to the best check PBW 343 and superior to all other checks in yield (q/ha). Similarly variety WH 736 was significantly superior to all checks other than PBW 343 in yield. The five check varieties differed in sensitivity to varying agroecological conditions. The check variety HUW 206 exhibited most co-adaptive nature and had similarity with three test entries UP 2527, WH 738, RW 3542 and a filler entry in sensitivity towards different levels of agronomic management used at different locations.
