A Study Of The Response Of Applied Zinc On Plant Growth In Sorghum Bicolor

P. Srinivas, Neeraj Jain.


This paper presents a detailed study investigating the response of applied zinc on the growth of Sorghum bicolor, commonly known as sorghum. Zinc is an essential micronutrient required for the optimal growth and development of plants. However, its deficiency is a widespread problem in many agricultural soils, leading to reduced crop yields. The objective of this study was to assess the impact of applied zinc on the growth parameters, including plant height, leaf area, biomass accumulation, and nutrient uptake in Sorghum bicolor.
The experiment was conducted in a controlled environment, where sorghum plants were grown in pots filled with a standard growth medium. Different levels of zinc application, ranging from 0 to 100 parts per million (ppm), were used as treatments. The growth parameters were monitored at regular intervals, and plant tissue samples were collected for nutrient analysis.
The results indicated that the application of zinc had a significant influence on the growth of Sorghum bicolor. The plants treated with higher levels of zinc exhibited enhanced growth compared to the control group. An optimal zinc concentration of 50 ppm resulted in the highest plant height, leaf area, and biomass accumulation. Furthermore, the nutrient analysis revealed that zinc application improved the uptake of other essential nutrients, such as nitrogen, phosphorus, and potassium, in the plants.
The findings of this study highlight the importance of zinc as a micronutrient for Sorghum bicolor growth. The results suggest that the application of zinc can effectively alleviate zinc deficiency symptoms and enhance plant growth parameters in sorghum crops. These findings have significant implications for agricultural practices, especially in regions where zinc deficiency is prevalent in soil.

Key words: Sorghum bicolor, zinc application, plant growth, micronutrients, nutrient uptake
