Accumulation and putrefaction of various wastes may cause several adverse effects on environment and living organisms including human health. Preparation of vermicompost (organic manure) from various organic wastes will save our environment as a whole; simultaneously organic wastes can also be managed properly. With this background for saving our environment from use of chemical fertilizers through proper management of agricultural wastes, an experiment was carried out in the farmer's field at village Bhabanipur, Block Haringhata, District Nadia, West Bengal, India) during the year 2013 -2014 with two crops (Rice-kharif/ rainy season and Lentil-rabi/winter season). It has been found that the application of vermicompost showed better result in comparison to chemical fertilizers in terms of soil physical and chemical properties as well as productivity of soil.
This study has measured firm-specific time invariant technical efficiency in the Indian automobile industry during 2004–06 using a suitably constructed stochastic production frontier. The one-sided inefficiency random variable is assumed to be truncated normal with a variable mode which is non-neutral with respect to some selected firm-specific factors, capable of explaining inter-firm variations in the level of technical inefficiency. It is found that age of the firm since inception and level of technical efficiency are inversely associated. However, the market share of the firm and the degree of automation are found to be positively associated with firm level technical efficiency. Statistical tests further reveal that the underlying technology in the automobile industry in India is linear homogeneous.
Resources are scarce, but needs are unlimited. Therefore, the rational attempt must be designed in order to allocate optimally the limited resources to satisfy as maximum as possible our dire needs of life. This chapter attempts to examine the impact of military expenditure (percentage of GDP) on health issues of five selected SAARC countries by employing the panel data model from the period 1995 to 2015. The authors have found that as military expenditure increased, total health expenditure (percentage of GDP), public health expenditure (percentage of GDP), and private health expenditure (percentage of GDP) decreased. The present study has also witnessed an inverse relation between population growth and health expenditure. Military expenditure adversely affected the two health indicators, namely life expectancy at birth and infant mortality rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
