Abstract

This article conducts an analysis of water balance indicators for the “Lazurniy” and “Sadaf” rice varieties. Through this analysis, the study aims to uncover insights into the water requirements and responses of these two rice varieties. The research findings reveal distinct characteristics of each variety in terms of their water usage and yield performance. The analysis underscores that the “Lazurniy” variety falls within the category of intensive type varieties. This designation is associated with its ability to thrive and deliver high yields in environments characterized by abundant agricultural resources. On the other hand, the “Sadaf” variety exhibits a different trait it showcases relative resistance to water shortage stress. This resilience suggests that the “Sadaf” variety has the capacity to maintain its performance even under conditions of limited water availability. By delineating these variations in water balance indicators, the research contributes to a deeper understanding of the adaptability and yield potential of both “Lazurniy” and “Sadaf” rice varieties. This information holds relevance for crop selection and management decisions, allowing growers to make informed choices based on the specific agro-environmental conditions they face. Ultimately, this analysis contributes to the optimization of rice cultivation practices by aligning crop varieties with their respective water requirements and stress tolerances.
