Abstract
Oats (Avena sativa L.) are the 6th-ranked crop (salt-sensitive) in the world, and common salt stress occurs in Pakistan. Salinity stress poses a significant threat to agricultural productivity worldwide, with its adverse effects on crop growth and yield being increasingly pronounced. The parameters used here are directed towards the efficiency of chitosan application as growth regulators to improve the negative effects of salinity stress on the growth of oats, such as plant height, chlorophyll content, relative water content, water potential, and yield. The experiment was carried out at Islamia University of Bahawalpur, Pakistan, to investigate the impact of chitosan on salt stress on oat plants. It was laid out in a completely randomized design with a factorial arrangement. Six treatments were provided by the two factors: salinity and chitosan application, and a positive relationship between chitosan foliar application and enhancing the performance of oat plants under salt stress conditions was found. The plant height (17.65%), grain weight (27.78%), grain yield (58.16%), biological yield (40.69%), harvest index (13.04%), RWC (20.90%), High WPP (10.19%), and Improved Chlorophyll content (43.72%) are consistently found superior in Chitosan treated oat crop than normal and only salt treated oat plants. The use of chitosan to improve the resilience of oats (Avena sativa L.) to salinity stress by evaluating the effects of different chitosan concentrations on plant growth.
