    An economic analysis of pesticide use in India: A case study of bathinda district
    (CESER Publications, 2017) Kaur, H.; Kaur, S.
    The excessive use of the pesticides in agriculture has not only increased production cost but also led to negative externalities. The present study is an attempt to analyse the socio-economic implications of pesticide use in Bathinda district known as the cotton belt due to its maximum area under cotton cultivation. An attempt has been made to find out the impact of pesticides on gross returns ofcotton and paddy crops as well as on the health of farmers and agricultural labourers and also to estimate the efficiency of cotton and paddy farms using different inputs including pesticides. The farmers and agricultural labourersengaged in the cultivation of cotton and paddy crops were randomly selected from two villages i.e. Laleana and Rayia respectively. The primary data was collected from 120 farmers and 80 agricultural labourers through structure schedules. The rate of return of pesticides for the cotton crop for large farmers (Rs. 13.40) was less than the medium farmers (Rs. 14.31) and the small farmers (Rs. 15.44). It was the highest for small farmers (Rs. 15.44) showing that it decreases with the increase in the expenditure on pesticides. Likewise, for paddy, the rate of return was less for large farmers (Rs. 18.56) as they incurred more on pesticides while the highest for small farmers (Rs. 22.67). Regarding the impact of different inputs used for returns of cotton, pesticides were significant and positive input while for paddy; labour was significant and positive variable. Usage of pesticides had a harmful effect on the health of farmers and agricultural labourers indicating that those were using manual backup sprayer face many problems. The proper awareness to farmers should be provided through various channels. ? 2017, [International Journal of Ecological Economics & Statistics].

    Electronic structure and simulated STM images of non-honeycomb phosphorene allotropes
    (American Institute of Physics Inc., 2018) Kaur, S.; Kumar, A.; Srivastava, S.; Tankeshwar, K.
    We have investigated the electronic structure and simulated STM images of various non-honeycomb allotropes of phosphorene namely ? - P, ? - P, ? - P and ? - P, within combined density functional theory and Tersoff-Hamman approach. All these allotropes are found to be energetically stable and electronically semiconductingwith bandgap ranging between 0.5-1.2 eV. Simulated STM images show distinctly different features in terms of the topography. Different maximas in the distance-height profile indicates the difference in buckling of atoms in these allotropes. Distinctly different images obtained in this study may be useful to differentiate various allotropes that can serve as fingerprints to identify various allotropes during the synthesis of phosphorene. ? 2018 Author(s).

    Human resource development, structural transformation, employment generation and innovation: India, China, Japan and South Korea, 1990-2016
    (Asociacion Euro-Americana de Estudios del Desarrollo, 2019) Bhat, G.F; Kaur, S.
    The speed at which the economy transforms is the crucial factor that determines the convergence or divergence of any country. In this connection, the present study aims to highlight the role of human development, productivity through innovation and structural transformation among the successful East Asian nations of China, Japan, South Korea and the Indian case for that of development. It is the vast gaps in productivity between the traditional agriculture sector and modern manufacturing sector responsible for the creating gaps among the successful East Asian nations and developing India. Such gaps may be minimized only through the investment in Human development, innovation, and technology. Increase in labor productivity will create jobs in the manufacturing sector, allow an increase in real labour incomes which is necessary for the poverty reduction and human development and crucial way of enhancing the standard of living as well. Furthermore, to improve the high tech exports, it is imperative to invest in skill development, technological advancement as done so far by the mentioned East Asian nations and is the sure way of enhancing productivity. India needs to foster its productivity measures for desirable structural change to create jobs through experimental and pragmatic policies as also claimed by Professor Dani Rodrik. The employment-oriented growth strategy is essential for harnessing the potential of demographic dividend in the growing working-age population of China and India. Furthermore creating jobs in small industries for which two-thirds of total employment in the Asia Pacific is vital for the inclusive growth especially in India.

    Phenological behaviour of Parthenium hysterophorus in response to climatic variations according to the extended BBCH scale
    (Blackwell Publishing Ltd, 2017) Kaur, A.; Batish, Daizy R.; Kaur, S.; Singh, H.P.; Kohli, R.K.
    Considering the importance of ecological and biological traits in imparting invasive success to the alien species, the phenological behaviour of an alien invasive weed Parthenium hysterophorus was documented according to the extended BBCH scale in four different seasons. A phenological calendar was prepared using both two- and three- digit coding system, precisely describing the developmental stages of the weed. The phenological documentation is further supplemented with the dates corresponding to a particular growth stage, pictures of the representative growth stages and meteorological data of all the four seasons. Results revealed that the phenology of the weed altered in response to the changing temperature and humidity conditions but no apparent climatic condition could inhibit its germination or flowering. However, the emergence of inflorescence was highly sensitive to the temperature/photoperiodic conditions. Variations in the phenological traits of P. hysterophorus with changing environmental conditions explain the acclimatisation potential of the weed permitting its vast spread in the non-native regions. Since the given phenological illustrations are accurate, unambiguous and coded as per an internationally recognised scale, they could be exploited for agronomic practices, weed management programmes, and research purposes. ? 2017 Association of Applied Biologists
