Opportunities and importance of growing linseed fiber in the Fergana Valley

Аннотация

This article scientifically substantiates the feasibility of cultivating flax fiber in the Fergana Valley. Field experiments were conducted to assess the adaptation of flax to agro-climatic conditions, as well as fiber yield and quality. The results demonstrated that flax is an environmentally friendly, low-resource, and economically viable crop. Flax cultivation could play a key role in diversifying the raw material base of the textile industry in the Fergana Valley. Keywords: Flax fiber, Fergana Valley, agro-climate, yield, ecological sustainability, textile industry. 485 “JOURNAL OF SCIENCE-INNOVATIVE RESEARCH IN UZBEKISTAN” JURNALI VOLUME 03, ISSUE 06, 2025.

From linse fiber materials used in quality fabrics, technical tissue and medical industries are made. The oil obtained from the seeds is widely used in the food, pharmaceuticals and chemical industries. In the context of Uzbekistan, there are prospects for leakage in areas where there is a high agro-assegating agricultural capabilities such as the Fergana Valley. Intensive culture of the main fiber source in Uzbekistan is high pressure on water resources, as well as the degradation and monocratic problems are intensifying. In this regard, resource savers and planting stable crops remain one of the most important issues. The linen deserves noteworthy as an alternative to these complicates in these requirements. However, the agro-technical foundations, profantability and practical results of linse growing in the Fergana Valley have been poorly studied. This article is aimed at filling this scientific gap. During the study, two types of linen - "Pskovsky" and the vegetation period in various agro-countriesis of the Fergana Valley (Fergana, Andijan and Namangan) were analyzed, productivity, fiber quality parameters. The effects of soil moisture, temperature, agrofone and agro-technical measures was observed. Based on the results obtained, the regional adaptation level and economic efficiency were evaluated. Foreign research on linen (A.N. Beketov, 2015; V. Romanov, 2020; FAO, 2022) provides its rich information on factors and technology that affect fiber quality. In Russia, Belarus and Canada, the lineage is being successfully grown on the industrial scale of flax. Full systematic research on this topic in science in Uzbekistan is not enough, mainly limited to historical agronomical observations. Therefore, modern methodic, based on local conditions, play an important role in innovative research .. METODOLOGY An experimental approach based on practical field tests and laboratory analysis was used in this study. Two varieties of linen - "Pskovsky" and "Vnilie" 486 “JOURNAL OF SCIENCE-INNOVATIVE RESEARCH IN UZBEKISTAN” JURNALI VOLUME 03, ISSUE 06, 2025.

The study covers the Vegetation period in 2023-2024. Data collection methods To collect data, the following parameters were measured regularly: Duration of vegetation period (days); • fiber yield (s / ha); • Seed yields (S / ha); • Fiber quality indicators: length, elasticity, hygroscopic; • Soil temperature and humidity; • Climate factors (air temperature, precipitation, sunlight), citing official data of the Hydromet service. Methods of analysis The result was a desertical statistical analysis. Average values, dispersions and reliability intervals on each variety (±)count. ANOVA (dispersion The impact of linen, sowing points and agro-technical measures was also statistically assessed by the analysis) (P < 0.05). Fiber quality indicators have been analyzed on the basis of the agreement of industry standards (GOST 10332-76). Experimental places Fergana district - Smoothal soil, moderary moisture; • Andijan district - irrigated ground soil; • Namangan district - Average climate, weakly saline lands. Equipment and machinery • Microscope and the length of the fiberalysis; • Drying a hygrometer and scale to detect moisture; • PH-mrs for soil analysis was used, EC regional and moisture sensor. Result of research The vegetation period of linen and adaptation to the agro-lif Pskovsky and Vniil varieties, which took part in the study, were planted in three districts of the Fergana Valley (Fergana, Andijan, Namangan). The growing season occurred between 85-100 days, which shows that it is fully consistent with the agro- assembly conditions of the region. The linen was highlighted in early spring (early 487 “JOURNAL OF SCIENCE-INNOVATIVE RESEARCH IN UZBEKISTAN” JURNALI VOLUME 03, ISSUE 06, 2025.
