Abstract
Nutrient Management plays a vital role in increasing crop production, soil
upgradation and healthy crop and as such is of great importance. Taking these things
into consideration a Decision Support System on fertilizer recommendation in Crops
(DSS) for selected zones of Karnataka has been designed and developed at University
of Agricultural Sciences, Dharwad. DSS is developed using Visual Basic 06 as a plat
form. DSS is a console application and provides decision to farmers on amount of
fertilizer application in crops. The system will have great importance in agriculture as
Experts are not always available to answer farmer’s queries.
The system is based on STCR approach. The procedure provides a scientific
basis for balanced fertilization and balance between applied nutrients and nutrients
available in the soil. The system has been developed total for 6 zones viz., Zone-3,
Zone-4, Zone-5, Zone-6, Zone-7 and Zone-8. Herein, the user gets an advice for
fertilizer application based on the information provided for soil test values and
targeted yield.
The testing and validation of the system for the zone-8 was done. The
developed decision support system is onpar with the farmers field condition in both
the crops i.e., for maize and chilli. If the farmer applied the fertilizer according to the
developed decision support system, they will get the same yield with a standard
deviation of 7 quintals/ha and C.V 12.75 per cent in maize and standard deviation of 2
quintals/ha and C.V 11.53% in chilli.
Fertilizer is not only the factor influencing the yield of a crop. There are many
factor which influence like management, rainfall, quantity and method of irrigation,
soil fertility, temperature, etc. Therefore, if we apply the fertilizer according to these
DSS or in any other approach the yield may vary.
