e-infrastructure Roadmap for Open Science in Agriculture

A bibliometric study

The e-ROSA project seeks to build a shared vision of a future sustainable e-infrastructure for research and education in agriculture in order to promote Open Science in this field and as such contribute to addressing related societal challenges. In order to achieve this goal, e-ROSA’s first objective is to bring together the relevant scientific communities and stakeholders and engage them in the process of coelaboration of an ambitious, practical roadmap that provides the basis for the design and implementation of such an e-infrastructure in the years to come.

This website highlights the results of a bibliometric analysis conducted at a global scale in order to identify key scientists and associated research performing organisations (e.g. public research institutes, universities, Research & Development departments of private companies) that work in the field of agricultural data sources and services.

Effect of levels of irrigation and fertility on yield and economics of chickpea (Cicer arietinum) and Indian mustard (Brassica juncea) under sole and intercropping systems


A field experiment was conducted during winter (rabi) season of 2005-06 and 2006-07 in the Agronomy Research Farm of Amar Singh College, Lakhaoti, Uttar Pradesh to study the effect of levels of irrigation and fertility on chickpea (Cicer arietinum L.) and mustard (Brassica juncea L. czernj & coss.) in sole and intercropping systems. The experiment was conducted in split-plot design with 3 replications. The combination of treatments consisted of 3 cropping systems, namely sole mustard (C(1)), sole chickpea (C(2)) and chickpea + mustard intercropping (C(3)) (4:1 raw ratio) and 4 irrigation levels [no irrigation (I(0)), irrigation at pre-flowering (I(1)), at pod formation (I(2)), at both pre-flowering and pod formation (I(3))] for chickpea allotted to main plots and 3 fertility levels [F(1) (20 : 40 : 10 kg N, P(2)O(5) and S/ha), F(2) (40 : 60 : 20 kg N, P(2)O(5) and S/ha) and F(3) (recommended dose of fertilisers (RDF)] for both the crops on row length basis to sub-plots. The sole Indian mustard recorded higher seed yield compared to intercropping. The yield reduction in mustard was to the tune of 58.9% and 60.0% in the first and second year, respectively, due to intercropping chickpea. Irrigation, on an average increased the mustard yield by 6.47% (I(1)), 12.18%(I(2)) and 13.18%(I(3)) compared to no irrigation (I(0)). Similarly fertilizer treatments F(2) and F(3) on an average increased mustard yield by 10.17% and 18.46%, respectively, over the F(1). The intercropping of chickpea and mustard in 4:1 raw ratio was significantly superior to sole crops of either chickpea or mustard in terms of yield and economics. Between the sole crops, chickpea was better as compared to mustard. Application of recommended dose of fertilizers (20 : 60 : 20 kg, N, P(2)O(5) and S/ha) on area basis was superior.
