Global wheat production faces a severe threat from drought stress, necessitating innovative strategies for enhanced crop resilience. This study explores the synergistic impact of biochar and potassium co-application on growth, physiological attributes, antioxidant defense system under water deficit conditions at crown root initiation (CRI), anthesis, grain development stage. Drought-induced reactive oxygen species (ROS) accumulation, particularly pronounced CRI stage, adversely affected all growth stages. At CRI, foliar delivered significant improvements in parameters, including increased plant height (15.4%), spike length (50%), yield (43.0%), photosynthetic performance (chlorophyll content 125.8%), relative (11.2%), compared to untreated drought-exposed counterparts. The combined application effectively reduced hydrogen peroxide production, electrolyte leakage, proline malondialdehyde generation, while increasing glutathione levels both well-irrigated stress conditions. Furthermore, treatment was effective mitigating oxidative enhancing resilience, during anthesis stage stress. Specifically, ameliorated effects by reducing ROS through enzyme activities elevating osmoprotectants levels. modulation osmotic balance holds promise drought-induced offering an practical strategy resilient water-limited environments.

BMC Plant Biology, Journal Year: 2023, Volume and Issue: 23(1)

Published: Dec. 5, 2023

Abstract Osmotic stress is a significant concern in agricultural crop production as it can harm growth, development, and productivity. Agriculture crops are particularly vulnerable to osmotic due their reliance on water availability for various physiological processes. Organic amendments like activated carbon biochar growth hormone gibberellic acid (GA3) play vital role. However, the time needed modify established amendment achieve better results. That’s why current study used potassium-enriched (KBC = 0.75%) with without GA3 (15 mg/L) under no wheat. Results showed that + KBC caused enhancement germination (9.44%), shoot length (29.30%), root (21.85%), fresh weight (13.56%), dry (68.38), (32.68%) (28.79%) of wheat over control (OS). A chlorophyll a, b total chlorophyll, while decline electrolyte leakage wheat, also validated effectiveness OS. In conclusion, most effective among all applied treatments improving attributes stress.
