Abstract:
The present study was aimed to study the effects of different zinc levels and sources on n the quality and micro- nutrient uptake of cotton in saline sodic soil. A pot experiment was conducted in Factorial Completely Randomized Design with three replications. The treatments consisted of three different sources of zinc namely zinc sulphate, zinc –EDTA and zinc humate and four levels of Zn (0, 1.25, 2.5 and 5.0 mg kg-1) and the variety MCU-7 was grown as test crop. The uptake of NPK was recorded at harvest. The results of the study indicated that soil application of Zn significantly increased the seed index and lint index and micro- nutrient uptake of cotton. Application of 2.5 mg Zn kg-1 of soil recorded superior seed index and lint index of 9.03 and 4.50, respectively. This was on par with application of 5.0 mg Zn kg<sup>-1</sup>. Similar trend was observed in micronutrient uptake of cotton. The present study concluded that 2.5 mg kg-1of Zn through zinc humate is the optimum dose for highest seed and lint index and maximum micronutrient uptake.
