In this paper we develop and implement a methodology for analysing the sources of variation in environmental efficiency across producers. We formulate a two-stage model. In the first stage we use stochastic frontier analysis to estimate both technical and environmental efficiency. In the second stage we again use stochastic frontier analysis to regress estimated environmental efficiency scores ...
Controlled-release fertilizers (CRF) use a controlled-release technology to enhance the nutrient use efficiency of crops. Many factors affect the release of nutrients from the waterborne polymer-coated CRF, but the effects of thermal post-treatments remain unclear. In this study, a waterborne polyacrylate-coated CRF was post-treated at different temperatures (30 °C, 60 °C, and 80 °C) and durati...
This study investigated seasonal patterns in stoichiometric ratios, nutrient resorption characteristics, and nutrient use strategies of dominant tree species at three successional stages in subtropical China, which have not been fully understood. Fresh leaf and leaf litterfall samples were collected in growing and nongrowing seasons for determining the concentrations of carbon (C), nitrogen (N)...
Field experiment was conducted at the Instructional Farm of Krishi Vigyan Kendra, Chhatarpur during two consecutive kharif 2017-18 and 2018-19 to evaluate effect different biofertilizers along with 75 % recommended dose fertilizers on growth, yield, nutrient uptake, use efficiency B:C ratio greengram (Vigna radiata L.). Results revealed that application NPK seed treatment Rhizobium @ 10 g/kg so...
It has been reported that phosphate solubilizing bacteria (PSB) are the most promising bacteria among the plant growth promoting rhizobacteria (PGPR); which may be used as biofertilizers for plant growth and nutrient use efficiency. Moreover, these soil micro-organisms play a significant role in regulating the dynamics of organic matter decomposition and the availability of plant nutrients such...
