Abstract

The present research on wheat was conducted during two consecutive rabi seasons (2020-22) at All India Co-ordinate Wheat and Barley Improvement Project, MARS, University of Agricultural Sciences, Dharwad The field research consisted of 15 treatments which are replicated thrice in a Randomized Complete Block Design (RCBD). Nowadays, farmers are trying to get high grain yields in line with food quality, at the same time trying to minimize production costs and to use environmental friendly technologies. The grain yield depends on the concentration and uptake of nutrients by the crop. There are various factors which influences the concentration and uptake of nutrients and among them climatic conditions, soil types, nature of crops and amount of fertilizers are important. Hence, the present investigation is proposed with the objective to study the uptake of major and micronutrients by wheat. The compiled data of two year study indicated that site specific management of nutrient strategy for achieving yield target of 55 q ha-1 by bread wheat significantly increased the concentration and uptake of nutrients by providing balanced nutrition tailored to the dynamic crop demand in the season. The study revealed that this particular approach is significantly superior over other approaches viz., soil test laboratory approach (STL), soil test crop response approach (STCR) and Nutrient Expert (NE) approach. Therefore, site specific management of nutrients is best approach for getting higher uptake of nutrients by wheat.

Conclusion

Site specific nutrient management approach for yield targeted at 55 q ha-1 significantly increased the nutrient concentration and their uptake of major and micronutrients in wheat when compared to other approaches such as soil test laboratory (STL), soil test crop response (STCR) and nutrient expert (NE), 125 and 150 per cent RDF and RPP.
