Recovery of capital investment in the superintensive apple-tree orchard depending on slender spindle crown formation

Abstract

Capital investments retrievement in apple superintensive orchards is greatly determined by the productivity of cultivated varieties and trees growing system. The investigations were made in the orchard „Codru-ST” Ltd. Founded in 2000 with bench-graftings on rootstock M 9 of the varieties Gala Must, Golden Reinders and Idared. The distance between rows is 4,0 m and that in the row is 1,0 m. There were studied 4 variants of crown formation. The highest yield in the first two years of fructification at the varieties under the study was registered at the variant V2 - 50,04-58,44 t/ha. Respectively, in variant mentioned the capital investments at foundation, keeping up the plantation and value of production were very high. Capital investments retrievement took place at all the variants under the study, but the greatest value was registered at pruning’s minimalization of crown formation and designing of 2 provisional branches.
