Influence of Zinc and Boron Fertilization on Grain and straw Nutrient Uptake in Rice (Oryza Sativa L) var. lET 5882

The influence of combined application of micro-nutrients, Zinc (Zn) and boron (B) along recommended dose of Nitrogen, Phosphorous and Potassium (NPK) markedly improved nutrient uptake of rice (Oryza Sativa L) under field experiment conducted during the kharif season for two consecutive years, at Sagara taluk, Shimoga district, Karnataka state, India. Seven treatments, including control, recommended dose of fertilizer (RDF, 120 : 80 : 60 N,P, K kg/ha), and RDF with ZnSO₄ (6–18 kg/ha), RDF with ZnSO4(6-18kg/ha) + boron(4 kg/ha),,their combination were evaluated in a randomized complete block design with three replications.Plots receiving zinc, boron along with NPK fertilizers resulted in significantly higher accumulation of NPK and Zn and B in grain and straw attributes These results highlight the synergistic role of Zn and B with NPK in addressing micro-nutrient deficiencies, enhancing nutrient use efficiency, and boosting rice productivity in Zn- and B-deficient soils, with implications for sustainable intensification
