The superiority and economical effectiveness of the variety “Khurma”. The variety adapted to the extreme soil-climatic conditions of the Khorezm region (saline soils, mineralized groundwater, water scarcity, high temperatures). This variety belongs to fiber type IV and meets the requirements of world standards due to its industrial value.
The average crop yield was 39-40 centners per hectare, 3-4 centners more than the standard variation, and the economic efficiency made up an additional 2-2.5 million sums.
Prospective variety “Khurma” has a higher yield (38.2-40.0 ts / ha) than the standard varieties, longer staple length of fiber (34.5-35.0 mm), softness of micronaire (4.3-4.5), higher fiber output (38-40%) compared to the standard and other varieties, as well as the fiber belongs to type IV.
According to the results of the study, cotton has high valuable economic characters and indicators, ripens 2-3 days earlier than the standard variety “Khorezm- 127”, high crop productivity, with fiber quality of type IV, high fiber output3 (38- 40%). It has been determined, that the variety “Khurma” yielded 38.7-40.0 centners per hectare. Nowadays the variety “Khurma” is cultivated in the irrigated fields of diversified agricultural farms in Khonqa, Urgench and Khiva districts of Khorezm region. Introduction of the variety “Khurma” is of great importance in solutions of problems connected with production of high quality seed materials, preserving morphological and valuable economic characters, as well as, with creation and implementation of medium staple cotton varieties, with fiber quality of type IV, more than 40% of fiber output, which is peculiar to new cotton varieties.

Average indicators of valuable economic characters of the new, promising variety “Khurma” cultivated in the experimental base of Khorezm Mamun academy, 2019 - 2021
