AGROTECHNOLOGICAL BASIS FOR CULTIVATING THE ‘BAGRYANY’ CULTIVAR OF AMARANTHUS CAUDATUS L. UNDER IRRIGATED SOIL CONDITIONS OF BUKHARA REGION

Abstract

This article presents the agrotechnological basis for cultivating the ‘Bagryany’ cultivar of Amaranthus caudatus L. under the irrigated soil and climatic conditions of Bukhara Region. During the field experiments, the effects of sowing dates and mineral fertilizer rates on plant phenological development, biometric parameters, green biomass yield, and grain yield were evaluated. The study employed methods of phenological observation, biometric measurement, yield assessment, and economic analysis. The results showed that this cultivar is well adapted to the conditions of the Bukhara oasis and has a high capacity for biomass accumulation. Among the studied sowing dates, March 30 was identified as the most optimal in terms of phenological development and yield indicators. The application of mineral fertilizers significantly increased plant height, number of leaves, individual plant weight, and yield. The biological maximum was recorded under the N120P90K60 treatment, whereas the highest economic efficiency was observed at the N90P60K45 fertilizer rate. The findings are of practical importance for the efficient cultivation of amaranth for fodder and grain purposes, rational resource use, yield improvement, and the development of scientifically based recommendations for farms. The obtained data also scientifically justify the possibility of introducing amaranth as an alternative crop on irrigated lands.
