Zinc Nutrition for Improving the Growth and Yield of Barnyard Millet (Echinochola frumantacea L.)

Aims: To evaluate the effect of various levels and methods zinc fertilization in improving growth yield barnyard millet at different stages.
 Study Design: Randomized Block Design (RBD) with three replications.
 Place Duration Study: A field experiment was conducted farmer’s Pasur village, Coimbatore district from January to April, 2022.
 Methodology: (Echinochloa frumentacea L.) var. MDU 1 by using ZnSO4 5, 10, 15, 20 25 kg ha-1 as basal soil application foliar spraying 0.25, 0.50 & 0.75% twice along test based NPK control replications. The parameters such plant height, SPAD index, root length, lateral volume, no. tillers, panicle weight, 1000 grain straw were recorded per standard protocols.
 Results: Application + performed better increasing height (157.0 cm), index (46.3), length (21.1 (16.3 volume (3.80 cc) attributes like number tillers (5.06), (17.6 weight (29.2 g) seed (3.89g) millet. Higher (2606 ha-1) (3411 also registered addition NPK+20 which 27.1% increase over NPK.
 Conclusion: Basal ha‑1 found optimal economical for variety 1.
