Influência da irriga??o na produ??o de pedúnculo e de castanha em clones de cajueiro-an?o-precoce

摘要

The goals of this work were to evaluate the influence of the irrigation on the cashew apple production and the ratio of apple: nut weights in dwarf cashew (Anacardium occidentale L.). Three clones were evaluated (CP 09, CP 76 and CP 1001), under four irrigation levels (A: control - without irrigation; B: irrigation with 1 day interval; C: with 3 days interval, and D: with 5 days interval). The experimental design was in randomized blocks, with split-split plots and four replicates, with irrigation levels in plots and clones in splited-plots, each one with four plants. The amount of water used was based on information from class A evaporation pan. The results led to the following conclusions: the response of dwarf cashew to the irrigation is dependent of genotype; CP 76 presents the biggest ratio of apple: nut weights, what elects in the clone more suitable for production of apples for in natura consumption; clone CP 1001 is more adapted for dry ground conditions.
