Abstract

A field experiment was conducted during the kharif season of 2022 at Instructional Farm, Alesur, Dau Kalyan Singh College of Agriculture and Research Station, Bhatapara (C.G.) to evaluate the “Efficacy of Solubilized Phosphorus on Plant Growth and Productivity of Rice (Oryza sativa L.)”. The experiment followed a Randomized Block Design (RBD) with 11 treatments, each replicated three times. Various growth parameters were measured at different stages of the rice crop, and the results were analyzed. The results demonstrated a significant impact of solubilized phosphorus on various growth parameters of rice. At 30, 60, 90 days after transplanting, and at harvest, treatment T5 (75% RDF + Solubilized phosphorus 4 ml/L) consistently exhibited the tallest plant height, the highest number of roots, and the maximum root length. It also resulted in the maximum number of leaves and tillers at 30, 60, 90 days after transplanting, and at harvest. Moreover, treatment T5 (75% RDF + Solubilized phosphorus 4 ml/L) showed the highest grain yield and straw yield at harvest, indicating its positive influence on the yield of rice. The study also examined the dry matter accumulation, crop growth rate, relative growth rate, leaf area index, harvest index, and phosphorus use efficiency. Treatment T5 (75% RDF + Solubilized phosphorus 4 ml/L) consistently showed the maximum values for these parameters at different stages of growth, suggesting its potential in enhancing rice productivity followed by T4 (75% RDF + Solubilized phosphorus 3 ml/L). Assessing the Impact of Solubilized Phosphorus on Rice Growth: Experimenting with 11 treatments, observing growth parameters, revealing significant yield boosts in treatment T5.

Conclusion

Grain yield (t ha-1) and Straw yield (t ha-1) were found significantly maximum in treatment (T5) 75% RDF + Soluble phosphorus 4 ml/L. Among the treatments, treatment T11 (Solubilized phosphorus 4 ml/) showed the maximum harvest index of followed by T8 (50% RDF + Solubilized phosphorus 4 ml/L). In conclusion, the treatment (T5) 75% RDF + Soluble phosphorus 4 ml/L, exhibited the best performance in terms of yield and phosphorus use efficiency followed by (T4) 75% RDF + Soluble phosphorus 3 ml/L. These results indicate that the application of solubilized phosphorus, in conjunction with reduced fertilizer dosage, can effectively enhance rice growth and productivity.
