    SCIENTIFIC AND THEORETICAL ASPECTS OF INCREASING THE VALUE ADDED OF FRUIT AND VEGETABLE PRODUCTS
    (The international scientific-practical conference «SCIENCE AND TECHNOLOGY: NEW APPROACHES AND DEVELOPMENT STRATEGIES», 2026-02-10) Gulomov Laziz Khudoyberdievich; Saidova Gulnoza Tulkunovna
    This article examines the scientific and theoretical aspects of increasing the value added of fruit and vegetable products. The study provides a theoretical analysis of the mechanisms for value added formation in the agricultural sector, as well as the interrelationships between production, storage, processing, and marketing processes. In addition, the factors contributing to improved economic efficiency through maintaining product quality, reducing losses, and adapting to market requirements are highlighted. Based on a review of scientific literature and existing conceptual approaches, priority directions for improving the value chain of fruit and vegetable products are identified. The research findings are of significant importance for the development of scientific and practical recommendations aimed at increasing value added in the agricultural sector.

    Experimental results of a combined machine for soil preparation and plastic film laying in melon crop production
    (E3S Web of Conferences 703, 2026-05-12) Farmon Mamatov; Khayriddin Fayzullaev; Nargiza Ravshanova; Laziz Gulomov; Shakhnoza Abduganiyeva
    Analyzed the current state of melon crop cultivation on rainfed lands of Uzbekistan with the application of plastic film mulching technology. Investigated the influence of combining soil tillage, seedbed preparation, and plastic film laying operations on the technological process of watermelon cultivation. Identified that the use of combined machines enables a reduction in the number of field passes during soil preparation. Studied the structural design of a combined machine incorporating chisel type working tools, rippers, leveling–compacting units, and a film-laying mechanism. Determined the functional purpose and interaction of the main working units ensuring the execution of multiple operations in a single pass. Established the compliance of the operational performance indicators of the prototype combined machine with agrotechnological requirements. Substantiated the application of the developed structural scheme for soil preparation and simultaneous plastic film laying on rainfed lands. Presented the results of field tests of the combined machine prototype conducted according to developed and standard testing methodologies.
