Abstract

The Bukhara region has continental climatic conditions and a tendency to salinity. Growth, development, productivity and its quality in newly created dwarf intensive pear orchards under drip irrigation have been studied. 3 varieties were studied - Williams, Abbot and Carmen and 6 planting patterns (4.0 x 1.0 m, 4.0 x 1.2 m, 4.0 x 1.4 m, 4.0 x 1.6 m, 4.0 x 1.8 m, 4.0 x 2.0 m), with medium-sized rootstocks on dwarf trees using water and resource-saving technologies. The correct methods of forming and pruning dwarf pear trees have been determined. The selection of tree crowns using optimal methods of protection against complex pests and diseases has also received scientific justification. Due to the correct distribution of light along the branches of trees, the aeration of pear orchards improves, which causes significant processes of growth, development and accumulation of fruit elements. As a result, it was found that the yield of 3-year-old young intensive pear orchards grafted on a medium-sized rootstock Quince C1 with drip irrigation, water consumption decreased by 2 times compared to traditional irrigation, and the yield increased to an average of 1.6 kg per tree
