Bioefficacy and phytotoxicity of herbicides in urdbean and their residual effect on succeeding transplanted basmati rice
A field experiment was conducted to evaluate the bioefficacy and phytotoxicity of herbicides in urdbean and their residual effect on succeeding transplanted basmati rice. The experiment was laid out in randomized block design with three replications. The major weed flora in summer urdbean were Cyperus spp., Cynodon dactylon, Digitaria sanguinalis, Solanum nigrum, Physalis minima and Phyllanthus niruri. In herbicidal treatments, Imazethapyr + pendimethalin (RM) @1000 g/ha as pre-emergence significantly reduced total weed density and total weed dry weight which was statistically at par with Imazethapyr + imazamox (RM) @ 80 g/ha at 3-4 leaf stage, Imazethapyr @ 80 g/ha at 3-4 leaf stage, Imazethapyr + imazamox (RM) @ 70 g/ha at 3-4 leaf stage and Imazethapyr @ 70 g/ha at 3-4 leaf stage. There was no visual phytotoxic on the urdbean crop. The seedling and plant did not show any abnormality during the crop growth period. Among the herbicidal weed management treatments, significantly highest number of pods/plant and seed yield were recorded with the treatment Imazethapyr + pendimethalin (RM) @1000 g/ha as pre-emergence which was statistically at par with Imazethapyr + imazamox (RM) @ 80 g/ha at 3-4 leaf stage, Imazethapyr @ 80 g/ha at 3-4 leaf stage, Imazethapyr + imazamox (RM) @ 70 g/ha at 3-4 leaf stage and Imazethapyr @ 70 g/ha at 3-4 leaf stage and remain superior over weedy check. There was no toxicity in terms of chlorosis and stunting were observed on succeeding transplanted rice crop at different intervals due to different weed management practices applied on summer urdbean crop. Different weed management treatments applied in urdbean were failed to show any significant effect on plant height and grain yield of succeeding transplanted basmati rice crop during the both years of cropping.
Influence of Tillage and Weed Management on Growth, Nutrient Uptake and Microbial population in Maize-Wheat Cropping System
Field experiments were conducted during kharif and rabi season of 2013-14 and 2014-15 at at the Research Farm of Division of Agronomy, Main Campus, Chatha, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, to study the effect of tillage and weed management on plant growth, weeds dynamics, nutrient uptake, Microbial population and yield of maize-wheat cropping system under irrigated conditions. The experiments were laid out in strip plot design with three replications. Main plot treatment consisted of four tillage methods viz., Zero tillage followed by Zero tillage (ZT-ZT), Zero tillage followed by Conventional tillage (ZT-CT), Conventional tillage followed Zero tillage (CT-ZT) and Conventional tillage followed by Conventional tillage (CT). Three weed management methods viz., Hand weeding, pre-emergence application of herbicide (atrazine @ 1 kg/ha for maize and metribuzin @ 200g/ha for wheat) and Weeding Check for both the crops consisted as the sub plot treatments. The soil of the experiment field was sandy clay loam in texture. The result revealed that among various tillage and weed management practices conventional tillage fb conventional tillage (CT-CT) and atrazine @ 1 kg/ha in maize and conventional tillage fb conventional tillage (CT-CT) and Hand weeding for wheat were found effective as compared to other tillage and weed management treatments in increasing plant growth, nutrient uptake (NPK) and yield, and also reduced in weed density and weed biomass. Although microbial population were higher in Zero tillage followed by Zero tillage (ZT-ZT) and weedy check as compare to other treatments in maize-wheat cropping system.
Computation of gear ratios for two-stage helical gearboxes with first stage double gear sets based on volume optimization
This paper introduces a new methodology for computing the volume of two-stage helical gearboxes with the first double gear sets. The volume of the gearbox is mentioned as the optimization problem. The six design factors such as the total gearbox ratio, the coefficient of the face width (CFW) of the first gear stage, coefficient of wheel face width (CWFW) of the second gear stage, the allowable contact stress (ACS) of the first stage, the ACS of the second stage, and the output torque were considered to design a screening experiment. To explore the influences of the design parameters on the optimum gear ratio, Minitab @18 was used to set up experiments. Moreover, technique tools i.e., regression and variance analysis were utilized to build the explicit model and to evaluate the reasonability of the model with experimental data. The results show that the optimal gear ratio can be simply computed from given design factors.
Effects of Flammulina velutipes soluble polysaccharides on the function and microstructure of myofibrillar protein gel system
The effect of Flammulina velutipes soluble polysaccharide (FVSP) on the gel properties of myofibrillar protein (MP) was investigated. Mixed gels were prepared by adding different concentrations (0.5%, 1%, and 1.5%) of FVSP to MP. The effects of different FVSP concentrations on MP gel properties were compared by measuring the whiteness values, gel strength, water holding capacity (WHC), Fourier infrared transform spectrum, and thermal denaturation temperature. Optical microscopy and scanning electron microscopy were also conducted. Results showed that FVSP addition increased the gel strength and WHC compared with those of the control. FVSP also enhanced gel formation and MP structure stability and produced a 3D gel matrix with high G' and G" values. Maximum gel strength and WHC were obtained at 1.5% FVSP concentration. Microscopy images showed that FVSP filled in the gel matrix and promoted a homogeneous and stable structure. In conclusion, FVSP addition substantially improved the gel properties of MP. This work provides scientific basis for the future application of FVSP in meat products.
Determination of Optimum Partial Gear Ratios of Two-stage Helical Gearboxes with Second Stage Double Gear-sets
This paper presents the results of a cost optimization problem for two stage helical gearboxes with second stage double gearsets. To do that, a simulation experiment was performed. The experiment consists of nine input parameters including the total gearbox ratio, the wheel face width coefficient of the first stage, the coefficient for determining the wheel face width coefficient of the second stage, the allowable contact stress of the first and second stage, the output torque, the cost of gearbox housing, the cost of shaft and the coefficient for determining the gear cost. Also, the experimental results were analyzed by the Analysis of Variance (ANOVA) method with the help of the Minitab 19 software. Moreover, a regression model to find the optimum gear ratio of the first stage was proposed.
