abstract
Wheat (Triticum aestivum L.) has been described as the "kin of cereals" and one of the most important staple food crops cultivated in at least 43 countries. This study, was conducted field experiment during rabi season of 2021-22 and 2022-23 at Shri Durga ji Post-graduate College Chandeshwar Azamgarh Uttar Pradesh, India. Investigating different micro nutrient management approaches with cost effective and plant need based micro fertilizer recommendations. These approaches provide principles and tools for supplying different dose of Zinc for crop nutrients to achieve higher yield. These methods not only aim to modify micro nutrient dose but also apply at optimal rate and time to achieve higher yield and nutrient efficiency by the crop. The wheat growing area Zn deficiency one of the major problems of wheat area. The experiment consisted five treatment and nutrient management options as applied in sources Zn in different treatments. T₁ -Control: seed soaking with distilled water (6 hours) and drying for 24 hours at NTP in shade +No. Zn addition T_2- Seed soaking with 4% solution of ZnSo4 (6 hours) and drying for 24 hours at NTP in shade, T₃ Seed soaking with 8% solution of ZnSo4 (6 hours) and drying for 24 hours at NTP in shade T₄- 26 kg of ZnSo4/ ha. As basal before sowing and T₅ 28 kg of ZnSo4/ ha. As basal before sowing. These treatments were replicated four time in a randomized block design in different plots. The results of the experiment indicate that significantly higher values of growth parameters (plant populations, plant height, fresh shoot weight, dry shoot weight, No. of leaves, No. of tillers,). Significantly higher plant height and No. of leaves and No. of Tiller of wheat was recorded is 60 and 90 DAS but 30 DAS were non-significantly effect with treatment T₅ (28 kg of ZnSO₄/ ha. As basal before sowing) over rest of the treatments except T₄ (26 kg of ZnSO₄/ ha. As basal before sowing). Application of T₅ (28 kg of ZnSO₄/ ha. As basal before sowing) recorded maximum No. of leaves, No. of tillers which was significantly higher over rest of the treatments except T₄ (26 kg of ZnSO₄/ ha. As basal before sowing) during both the years experimentations. Fresh shoot and Dry shoot accumulation at 30 DAS was not significantly influenced by micro different nutrient management options with applications Zn. Which, application of T₅ (28 kg of ZnSO₄/ ha. As basal before sowing) recorded maximum fresh shoot and dry shoot weight at 60 and 90 DAS which was superior over rest of the treatments except T₄ (26 kg of ZnSO₄/ ha. As basal before sowing) on pooled basis and yield attributes (No. of productive tillers, length of spick No. of grain spick, grain yield, straw yield, biological yield, harvest index and test weight) of wheat were recorded significantly Superior performance of growth and yield attributes resulted in T₅ 28 kg of ZnSo4/ ha. As basal before sowing significant enhancement in grain, straw and biological yield. The wheat is maximum recorded 40.63, 41.86 and 41.25 grain yield and 58.59,59.88 and 59.24 straw yield and biological yield 99.22,101.74 and 100.48 q ha^-1 higher with both year, of the experimentations respectively.
