MAYMUNJONNING (RUBUS CAESIUS, RUBUS FRUTICOSUS) NAVLARINI MINERAL O‘G‘ITLAR BILAN OZIQLANTIRISHDA ME’YOR VA MUDDATLARNI HOSILDORLIKKA TA’SIRI

Abstract

In this article, the influence of fertilizer rates and application dates on the yield of Rubus caesius and Rubus fruticosus blueberry varieties during mineral fertilizer application was studied. During the study, various rates of nitrogen, phosphorus, and potassium fertilizers were applied, and their impact on plant growth, vegetative development, and yield was analyzed. According to the results, it was found that the application of mineral fertilizers at optimal rates and agrotechnical deadlines significantly increases the yield of blueberries. In particular, the application of nitrogen fertilizers in early spring and phosphorus and potassium fertilizers before flowering yielded effective results.This article examines the influence of various mineral fertilizer rates and application periods on yield, fruit quality, and vegetative development of Rubus caesius (forest monkey-berry) and Rubus fruticosus (garden monkey-berry) varieties under Uzbekistan conditions during 2021-2024.
