   Abstract. The present study of the reproductive ability of currant and gooseberry hybrids after long-term cryopreservation of pollen in liquid nitrogen is of enormous importance for organizing the conservation of the diversity of this crop. Four distant interspecific hybrids of currant and gooseberry served as objects of the study. The pollen fertilizing ability was studied by pollination of allotetraploid Jošta with pollen of tetraploid hybrids stored for a year at ultra-low temperatures (–196°C) and freshly collected pollen (control pollination). Berry set in 2022, when pollinated with cryopreserved pollen, averaged 56.…

   Abstract. Uganda has the world's lowest fertilizer use rate at just 1-1.5 kg per hectare. This limited use is a key factor hindering rice productivity in the country. Farmers can use affordable organic fertilizers to partially replace expensive mineral fertilizers, increasing the profitability of rice cultivation. This study focused on identifying the optimal combinations and application rates of inorganic fertilizers and organic inputs to enhance the yield and profitability of irrigated rice, particularly by varying nitrogen levels, the most limiting nutrient. Using a combination of organic and inorganic fertilizers impr…
