Caracterização agronômica de morangueiro de segundo ciclo em diferentes formas de cultivo em sistema orgânico de produção

Abstract

The objective of this research was to agronomically characterize second-cycle strawberry plants in different forms of cultivation in an organic production system. The cultivars used were RANDOCE (short day) and BELLA (neutral day). The materials were grown in soil, gutters, slabs and pots. The period of execution of the experiment was from April 2021 to January 2022. The experimental design adopted for each cultivar was completely randomized in a 4 x 10 factorial scheme (four cultivation methods x ten months of evaluation). Three replications with five plants each were used, totaling 120 plants. The evaluations carried out were: FBE-BH (flower bud emission until the beginning of the harvest), DP-BE (drastic pruning until the beginning of stolon emission), plant height, plant diameter, number of crowns and total chlorophyll content. The data obtained were submitted to the Scott-Knott test at 5% probability. The cultivation in seedbeds provided a shorter time between the emission of the floral bud until the beginning of the fruit harvest (FBE-BH), for both evaluated cultivars, being 27.5 days for RANDOCE (short day) and 25 days for BELLA (neutral day). The longest time to start the emission of stolons in the RANDOCE cultivar was obtained in the gutter form of cultivation in a 300-day. Cultivation BELLA took 261 days in the form of cultivation in vase, with no emission of this on the slab. Plants with greater diameter, height, number of crowns and total chlorophyll were verified using gutters for the RANDOCE cultivar (short day). For cultivar BELLA (neutral day) higher values were obtained with cultivation in pots.
