Estimation of Fertilizer Requirement for Targeted Yield

Abstract

Based on a chemical examination of the soil, STCR is a quantitative method to suggest fertilizer doses for achieving the desired yield. The strategy is based on the presumption that a specific quantity of fertilizers must be ingested by the plant as absorption for the plant to produce a specific yield. To determine the amount of fertilizer required to produce a desired yield, the STCR technique develops fertilizer prescription equations that take into consideration the chemical properties of the soil. The approach has seen extensive application since it was developed as an AICRP project in 1967. The technique is predicated on the idea that the plant’s ability to absorb certain nutrients depends on the interaction between that nutrient present in the soil and in the applied fertilizer. Several studies support the idea that all the type of fertilizers used to feed the plant affects how much of a specific nutrient is absorbed. The reliability of fertilizer prescriptions made using the existing STCR approach is called into question because of the aforementioned shortcomings. We have created a new mathematical model for a targeted yield to address the shortcomings in the STCR technique. Data from carrot plantations were used to illustrate the model suggested by us.
