        <p>In increasing watermelon yield, improving the laboratory and field germination of the seeds to be sown and disinfecting them against various diseases are of great practical importance in agriculture. In this regard, developing a special device for ultraviolet (UV) irradiation of watermelon seeds and increasing the efficiency of its use is a pressing issue. The aim of the research is to conduct experimental studies on a laboratory prototype of a device for UV irradiation of watermelon seeds and to determine the most rational irradiation modes. The experiments were carried out on a laboratory stand of the UV device, in four replications, using bactericidal lamps with a power of 120–180 W and wavelengths of 253.7 nm and 300 nm. Different modes, varying in the distance between the seeds and the irradiator and in the treatment time, were compared with one another, and the results of the analysis are presented.</p>

        <p>В деле повышения урожайности арбуза повышение лабораторной и полевой всхожести высеваемых семян и их дезинфекция против различных болезней имеют важное практическое значение в сельском хозяйстве. В связи с этим разработка специального устройства для ультрафиолетового (УФ) облучения семян арбуза и повышение эффективности его использования является актуальной задачей. Целью исследования является проведение экспериментальных исследований на лабораторном макете устройства для УФ-облучения семян арбуза и определение наиболее рациональных режимов облучения. Эксперименты проводились на лабораторном стенде УФ-установки в четырехкратной повторности с использованием бактерицидных ламп мощностью 120–180 Вт и длиной волны 253,7 нм и 300 нм. Сопоставлены различные режимы, различающиеся расстоянием между семенами и облучателем, а также временем обработки, и представлены результаты анализа.</p>

        <p>Maqolada tarvuz hosildorligini oshirishda ekiladigan urug‘larning laboratoriya hamda dala unuvchanligini yaxshilash va ularni turli kasalliklardan zararsizlantirish qishloq xo‘jaligida muhim amaliy ahamiyatga ega. Shu munosabat bilan tarvuz urug‘lariga ultrabinafsha nur (UBN) beruvchi maxsus qurilmani ishlab chiqish va undan foydalanish samaradorligini oshirish dolzarb masala hisoblanadi. Tadqiqotning maqsadi tarvuz urug‘iga ultrabinafsha nur berish qurilmasining laboratoriya nusxasida eksperimental tadqiqotlar o‘tkazish hamda nurlatishning eng ratsional rejimlarini aniqlashdan iborat. Tajribalar UBN qurilmasining laboratoriya stendida to‘rt qaytariqda, to‘lqin uzunliklari 253,7 nm va 300 nm bo‘lgan 120 – 180 Vt quvvatli bakteritsid lampalarda o‘tkazildi. Urug‘lar va nurlatgich orasidagi masofa hamda ishlov berish vaqti bo‘yicha turli rejimlar o‘zaro solishtirilib, tahlillar natijalari keltirilgan.</p>
