The present paper studies the regional disparities in structure of investment in agricultural research and education and assess the productivity gains in agriculture arising out of research investment. Results observed that all the States showed impressive growth in research investments and spent more on agricultural research relative to their agricultural gross domestic product (agricultural research intensity) in 1992-94 than they did in 1980-82. Results also indicate an association between high growth rate in real investment in research and education and growth in average value of yield per hectare in all states except West Bengal.

The present paper deals with adsorption of Fe (ii) on Accacia bark. The variation in pH of the solution has no effect on the basic nature of time growth or adsorption time or saturation period. The adsorption was initially rapid and finally became constant due to slow removal near saturation. The extent of adsorption varies significantly with change in pH of the solution and attained a peak level to 74 per cent at pH 5.5 and thereafter decreased to 56.4 per cent at pH 9.5. It is obvious from results that pH of the medium plays an important role in adsorption of Fe (ii) from metallic solution.Keywords

The environmental cost of increased fertilizer application is an emerging concern, worsened by farmers’ reluctance to adopt alternative fertilizer products. The right fertilizer must be applied at the correct rate and time at the right place for maximum benefit. However, empirical evidence from across the world suggests a deviation from these normative strategies. Considering the lack of a holistic overview of the knowledge structure of the growing literature on fertilizers, we conducted a bibliometric analysis using data extracted from the Web of Science Core Collection database. We identified the publication trend and the important authors, journals and countries contributing to research on fertilizers. In addition, the topics that have received research attention were also identified. We can locate that issues like nitrogen fertilizers and their effect on growth and yield will never lose relevance. Most importantly, researchers are now dealing more with topics related to the externalities of chemical fertilizer use. Our findings will help interested researchers to gain systematic insights into the knowledge structure of fertilizer research.Keywords
