Abstract

A field experiment was conducted during Kharif season 2020 at SHUATS university Allahabad, (U.P.). The soil of experiment plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.2), 0.35% organic carbon, 203.7 kg ha-1 nitrogen, 7.2 kg ha-1 available phosphorus. The effect of sulphur and zinc levels growth and yield of maize (Zea mays L.) nine treatment consisted of three levels of Sulphur (15, 25 and 35 kg ha-1) and Zinc (0.5% foliar application, 25 kgha-1 soil application and 20 kg/ha+ 0.5 % foliar application). In the experiments nitrogen was applied in two split doses 50% as basal and 50% as top dressing at 40 DAS and entire dose of phosphorous, potassium and sulphur were applied as basal and where foliar application of zinc were applied at 20 and 35 DAS. There were nine treatments which replicated thrice. The experiment was laid out in Randomized Block Design. The result showed that there was significant increase in growth and yield parameters viz., plant height (1

Conclusion

At above research, it may concluded that in Maize crop the application of Sulphur 35 kg/ha + Zinc 20 kg/ha (Soil application) + Zinc 0.5 % (Foliar application) is the best combination for obtaining better growth attributes like plant height, number of leaves/plant, dry weight and higher yield attributes of hybrid maize like number of cob/plant, cob length (cm), number of grain/cob, seed index (g), grain yield (t/ha), stover yield (t/ha), and can be recommended to the farmers of Allahabad region for sustaining productivity and profitability of maize.
