Influence of different level of sulphur and zinc on physico-chemical properties of soil yield attributes and nutrient content of maize (Zea mays L.) Shakti 8484

Abstract

An experiment was conducted on "Influence of different level of Sulphur and Zinc on Physico-chemical Properties of Soil yield attributes and Nutrient content of Maize var. Shakti-8484 was executed at the department of Soil Science and Agricultural Chemistry NAI, SHUATS (Allahabad) Prayagraj. The trial was conducted in RBD designed having three level of sulphur and zinc respectively, it was found that the effect of Sulphur and Zinc on soil physical parameters viz., pore space (%) ranged from 54.30% to 67.77%, water retaining capacity ranged from 45.36 to 63.22 and organic carbon (%) ranged from 0.46 to 0.69 and on soil chemical parameters viz., Av. Nitrogen (Kg ha -1 ) ranged from 242.86 to 267.83, Av. Phosphorus (Kg ha -1 ) ranged from 22.14 to 34.73, Av. Potassium (Kg ha -1 ) ranged from 165.71 to 220.31, Av. Sulphur (mg kg-1) ranged from 9.25 to 18.07 and Av. Zinc (mg kg -1 ) ranged from 0.50 to 1.59 were significant and effectively came out in Treatment 9.This effect enhances the formation of protein and ranks along with nitrogen and phosphorus. However, S and Zn nutrient uptake by plants increases with the application of sulphur up to 40 kg ha -1 and Zn up to 10 kg ha -1 depending on the sulphur and zinc status having protein percentage in maize ranged from 9.40% to 11.75%. A panoramic view of sulphur and Zinc nutrition in maize has been reviewed in this chapter.
