There are several factors and technological issues suchas fiber nonlinearity and dispersion which are responsible fordegrading the performance of a system. There must be some way outto transmit an error-free signal over a certain distance. Thus themodulation format plays a very significant role in the overall systemperformance in communication technology. The choice of optimummodulation format has always been a challenging task because thereis no fixed criterion available for it. This has inspired us to study andanalyze all these aspects of modulation formats in OWDM/DWDM.In this paper, we have analytically evaluated the effect of higherorder dispersion and phase modulation on Alternate Chirp NRZ(alCNRZ)) modulation format. We have mathematically evaluatedthe output electric field in the presence of higher order dispersion andphase modulation index. Their results are also presented analyticallywith first, second, third and fourth order dispersion compensation aswell as for different values of phase modulation indexes in order topresent a signal which can be transmitted throughout its path withoutany degradation in its quality and quantity.

The experiment on natural parasitization of sugarcane leaf hopper, Pyrilla perpusilla was conducted at Crop Research Center of G.B. Pant University of Agriculture and Technology, Pantnagar. The maximum number of egg mass, nymph and adult per leaf of pyrilla observed was 6.67, 22.67and 18.00 on 30th, 30th and 15th August, respectively. The highest parasitization of eggs masses by Tetrastichus pyrillae was observed in the month of October i.e. 85.33% indicating peak activity of parasitoid. The maximum population of egg, pupa and adult/ leaf of E. melanoleuca were 8.00, 27.33 and 18.67 on 30th Sept., 30th Oct. and 15th of Oct., respectively.Keywords

To contend the market in the existent state, cost efficacy is vastly desired. For that, productivity improvement technique is among the many ways [1]. Submerged Arc Welding (SAW) is used as a productivity improvement method in the present paper where manufacturing process of fabricated parts are not only curtail by tumbling the process time, moreover by strengthening the weld quality too. Efforts are initiated to improve the productivity of the fabrication department of one of the industrial set up under study is taken by achieving the tensile strength of the weld bead in single pass only. In this process, conventional flux is supplemented by alloying in variations to achieve the optimal tensile strength, which are further verified by one of the optimisation method. The effect of input parameters are analysed over the output response and observed that one parameter has more substantial effect on the tensile strength than the other remaining parameters.Keywords

Biostimulant is a substance or microorganism, or a combination of both, which stimulates the physiological activities of plants, leading to increased uptake and efficiency of nutrients, crop quality and tolerance to stress related to biotic and abiotic factors. Biostimulant helps optimise crop productivity and enhances the quality of the produce, which help maintain an eco-friendly environment to sustain agricultural production. Various botanical extracts, biochemicals, protein hydrolysates and amino acids, vitamins, cell-tree microbial products, antioxidants, anti-transpirants, humic and fulvic acids, and their derivatives are included under biostimulants. Recently, the fertilizer (inorganic, organic or mixed) Control Amendment Order, 2021, has been passed by the Government of India to promote biostimulants in the country. The Central Biostimulant Committee advises on various matters related to biostimulants. Participation of stakeholders, farmers, researchers, policymakers and regulators is essential to popularize biostimulants for their profitable and sustainable usage. This article focuses on various aspects of biostimulants, including regulatory aspects in India.Keywords
