NATIONAL INFORMATION
SYSTEM ON LONG TERM
FERTILIZER EXPERIMENTS
(NISLTFE)
INDIAN AGRICULTURAL STATISTICS RESEARCH INSTITUTE, NEW DELHI-110012
Objectives
• To collect, collate and compile the data on long term
fertilizer experiments.
• To design and develop a database for long term
fertilizer experiments.
• To develop a user-friendly web-based information
system on long-term fertilizer experiments.
• To evolve suitable mechanism for maintenance, inflow
and updating of the information system.

Source of Information
 The key source of data information for NISLTFE is the
data generated under long term fertilizer experiments
conducted/ in progress at various organizations under
different divisions of ICAR.
 For this linkages with organizations engaged in LTFE were
established to acquire the experimental information
available on various aspects of agro technologies since their
initiation.
 About 25 scientists at these locations have been nominated
as Nodal Officers by their respective Heads of Institutions
for this purpose..
 So far a maximum number of 59 experiments under NRM
followed by 11 and 4 experiments under Crop Sciences and
Horticulture divisions have been identified for entering
their data under the system.

Architecture of NISLTFE
•
•
•
•
NISAE has been developed as a web-based application
using JAVA technology.
Therefore, it is platform
independent and can be connected from any computer
connected to the Internet. The user only has to confirm that
computer has a Web-browser. The architecture using threelayered structure is:
Client Side Interface layer (CSIL)
Server Side Application layer (SSAL)
Database layer (DBL)

Client Side Interface Layer (CSIL)
• The client side interface layer has been developed by using
HTML, JavaScript using browser as front-end. This interface
enables incorporating the validation checks in data entry
forms. NISLTFE runs at any node of the network through
browser. To run the NISLTFE with full functionality one must
have internet explorer 5.0 or Netscape Navigator pre-installed.

Server Side Application Layer
(SSAL)
• Server side application layer is implemented using Java Server
Pages (JSP). These JSP generate HTML pages according to the
users' action and request.

Data Base Layer (DBL)
• Database used for the development of NISLTFE has been
structured using SQL Server 2000. The tables with their
respective content fields and other specifications are
designed using the relational database approach and proper
normalization.
