Impact Of Gamma Radiations And Sugarcane Baggase Fibers On Various Growth Parameters Of Maize (Zea Mays L)

Abstract

The present study was conducted to investigate the effects of gamma radiations on the morphological and biochemical characteristics of the maize (variety: CS-2Y10). Seeds were exposed to gamma radiation treatments at varying doses, ranging from 15 Krad to 55 Krad. The study evaluated key agronomic parameters, including seed germination, plant height, number of leaves, fresh and dry weight of leaf, leaf length, number of nodes, fresh and dry stem weight, stem length, cob length, seed count per cob, fresh and dry root weight. Spectrophotometric analysis was employed to assess moisture content, ash, crude fat, crude fibre, crude proteins, carbohydrates, and energy (Kcal). The findings revealed that the control group (non-irradiated) and the group exposed to 15 Krad revealed more growth compared to the higher doses (25 Krad, 35 Krad, 45 Krad, and 55 Krad). Parameters such as plant height, cob length, seed count per cob, fresh and dry weight of roots and stems were notably impacted. Lower doses of gamma radiations demonstrated a significant positive effect on biochemical traits. Additionally, the inclusion of sugarcane bagasse fibres in gamma- irradiated plants led to enhanced growth characteristics. Remarkably, protein and carbohydrate contents increased with moderate radiation doses and decreased at lower doses. The study concluded that gamma radiation doses of 15 Krad and 25 Krad significantly promote maize plant growth, whereas higher doses, particularly 35 Krad and 45 Krad, hinder growth, with plant development completely halting at 55 Krad.
