“…This regulation aids in nutrient distribution towards generative plant organs, ultimately contributing to increased dry matter accumulation. This finding aligns with previous studies by Amanullah and Inamullah [17], Ghoneim[11], andSaikh et al (2022), which also reported increased dry matter accumulation in rice following zinc application via soil and foliar methods[18].…”

Aims: To investigate the effect of different establishment methods, zinc application and residue retention on the rice plant growth metrics. Study Design: Split-plot design with three replications. Place and Duration of Study: Rice and Wheat Research Centre-CSK HPKV, Malan, Kangra, Himachal Pradesh, India. The study was conducted during Fall of 2021 and 2022. Methodology: We used six main plot treatments viz., M1: transplanting, M2: wet seeding (line sowing under puddle condition), M3: aerobic rice (dry rice cultivation), M4: transplanting + soil application of ZnSO4 (12.5 kg ha-1 + 0.5% ZnSO4 spray) at flowering and early milk stages, M5: wet seeding + soil application of ZnSO4 (12.5 kg ha-1 + 0.5% ZnSO4 spray) at flowering and early milk stages, M6: aerobic rice + soil application of ZnSO4 (12.5 kg ha-1 + 0.5% ZnSO4 spray) at flowering and early milk stages, and three subplot treatments, S1: no residue, S2: 15 cm height of rice straw from ground and incorporation in soil and S3: 30 cm height of rice straw from ground and incorporation. The variety used in the investigation was HPR 1068 of rice. Results: The zinc was treatment resulted in significantly better rice plant height, leaf area index, crop growth rate and net assimilation rate when coupled with transplanting establishment method. Conversely, the aerobic rice establishment without zinc application resulted in significantly (P<0.05) lower rice growth attributes. The days to flowering and physiological maturity were not significantly influenced by the treatments during the study. Conclusion: The transplanting in conjunction with soil application of ZnSO4 12.5 kg ha-1 and foliar application of ZnSO4 0.5% at flowering and early milk stages resulted in significantly higher and better rice plant growth and hence is encouraged.

A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P) to determine the “Influence of Varieties and Foliar application of Zinc on Growth , Yield and Economics of Rice (Oryza sativa L.)”. The soil of the experimental field was sandy loam in texture, nearly neutral in soil reaction (pH 7.8), low level of organic carbon (0.62%), available N (225 Kg/ha), P (38.2 kg/ha) and K (240.7 kg/ha) and the treatments consisted of 3 different Zinc viz. (0.5%), (1.5%) and (2.5%) with combination of 3 Varieties viz. BPT5204, RNR15048, and KNM118. The experiment was laid out in RBD with 9 treatments each replicated thrice The results showed that treatment 9 [BPT5204+ Zinc(2.5%)] recorded significantly higher plant height (113.77 cm), , maximum number of tillers/hill (12.80), higher plant dry weight (54.13g),maximum number of effective tillers/hill (12.50) ,maximum number of panicles/plant (10.20),maximum number of grains/panicle (104.70), higher test weight (18.70 g), higher grain yield (5.81 t/ha), maximum straw yield (5.92 t/ha) and higher harvest index (50.19 %) compare to other treatment. The maximum gross returns (1,62,773.00 INR/ha), net return (1,10,546.50 INR/ha) and highest benefit cost ratio of (2.12) was recorded.

“…Leaf zinc application parallels the advantages of rapid and effective utilization of nutrients and reduction of losses through washing, fixation, and regulating the plant nutrient uptake (Saikh et al, 2022). Foliar application can avoid the problem of zinc fixation in soil; however, the time of zinc application should be around flowering to increase the granular Zn concentration.…”

The concerned study aimed to determine the correlation and direct and indirect effects to estimate the interaction between production parameters and the zinc content of plant tissues of early maturing rice (Oryza sativa L.) cultivars. The study comprised the application of zinc at various crop phases, namely, without zinc (Zn0), zinc at the vegetative phase (Zn1), the vegetative and generative phases (Zn2), and the generative phase (Zn3) to three early maturing rice cultivars, Inpari 19, Inpari Cakrabuana, and Inpari Sidenuk. Data analysis used correlation and path analyses. The results revealed that rice grain yield positively correlated with most production parameters. The zinc analysis also showed a positive correlation between zinc content and rice plant tissues. The path analysis indicated that the clumping grain weight had a significant (P ≤ 0.01) positive direct effect (0.75). Meanwhile, panicle density had a significant (P ≤ 0.05) positive direct effect (0.51) on rice grain production per hectare. Path analysis of zinc content in tissues signified that zinc content in leaves had a very significant (P ≤ 0.01) positive direct effect (0.71), In contrast, zinc content in stems had an indirect positive influence (0.33) on zinc content in grain.
