ТУПРОҚ ШЎРЛАНИШИ ШАРОИТИДА ШОЛИ (ORYZA SATIVA L.) ГЕНОТИПЛАРИНИНГ ХЛОРОФИЛЛ МИҚДОРИ БАРҚАРОРЛИГИНИ БАҲОЛАШ
Keywords:
rice, salinity, chlorophyll, SPAD, chloride salinity, sulfate salinity, yield.Abstract
The study evaluates the impact of chloride and sulfate salinity on rice chlorophyll content (SPAD) and yield. Chloride salinity was found to be 1.2–1.5 times more toxic than sulfate. A decrease below 40 SPAD units was identified as a key indicator limiting productivity. The Gigant and Manzur varieties demonstrated high resilience and are recommended for saline soils.
