Efficacy of Nutripearls Fertilizer on Yield Components and Productivity of Transplanted Rice (Oryza sativa L.)

Abstract

A field experiment was carried out during the Kharif season of 2022 at the Research Farm of the Department of Agronomy, JNKVV, Jabalpur (M.P.), to evaluate the effects of Nutripearls, an organic acid-based granular fertiliser, on the yield components and productivity of transplanted rice (Oryza sativa L., cv. JR 206). The trial was laid out in a Randomised Block Design (RBD) with nine treatment combinations involving graded levels of the Recommended Dose of Fertilisers (RDF) and Nutripearls applied at the tillering and panicle initiation (PI) stages. The results demonstrated significant variations among treatments in yield attributes and overall productivity. Application of 100% RDF + Nutripearls @ 50 kg/ha at the tillering and PI stages (T2) recorded superior growth and yield parameters, including the maximum number of effective tillers (406.5/m2), panicle length (27.87 cm), and sound grains per panicle (196.27), along with the lowest number of sterile grains per panicle (6.47). Consequently, T2 produced the highest straw yield (7582.20 kg/ha) and harvest index (43.91%), markedly outperforming both 100% RDF alone (T8) and the untreated control (T9). Higher doses of Nutripearls (75 kg/ha and 100 kg/ha) did not offer significant improvements over the 50 kg/ha rate. Overall, integrating Nutripearls at 50 kg/ha alongside 100% RDF can enhance nutrient availability and crop partitioning efficiency, indicating its potential for maximising transplanted rice yields under the experimental conditions.
