“…Cardoso & Ustulim Filho (2013), using the same cultivar, obtained an average height of 18.4 cm and the highest fresh matter of 389 g. For fresh matter, Reghin et al (2007) obtained 332-407 g, very similar results obtained in this study (372 g of fresh matter in the best treatments). The values are also similar to those obtained by Feltrim et al (2006) and Sá & Reghin (2008).…”

The authors evaluated the effects of doses of organic compost on the production and accumulation of macronutrients in endive plants in two areas with different fertility levels. The experiments were carried out at Fazenda Experimental São Manuel, located in the municipality of São Manuel, São Paulo State, Brazil. The study was carried out in a completely randomized design with seven treatments, six doses of organic compost (0, 35, 70, 105, 140 and 175 t/ha) and one additional treatment with inorganic fertilizer (N-P-K 4-14-8) and four replicates. In both areas, when the dose of organic compost was increased, the authors noticed a linear increase in fresh matter weight, number of leaves and plant height. In high-fertility area, compared to control (dose 0), using the highest dose (175 t/ha), the authors observed an increase of 280, 58 and 101% in fresh matter weight, number of leaves and plant height, respectively. For dry weight, we observed a linear increase in low fertility area and quadratic effect in high fertility area, with maximum estimated dry matter of 22.26 g applying 144 t/ha of organic compost. The nutrient accumulation was proportional to dry matter, with a linear increase in low fertility area and quadratic effect in high fertility area. The decreasing order of accumulated nutrients was K>N>Ca>P>S>Mg, with the highest values, in high fertility area, of 1,269, 471, 185, 91, 53 and 35 mg/plant, respectively, for doses varying from 121 to 158 t/ha.

“…This may be due to the low temperatures during P2 and P3 (Table 1). According to Sá & Reghin (2008), minimum temperatures of 8 and 9°C may slow escarole development, consequently, as observed in this study, it was necessary to increase the number of days to reach the harvest point that is not desired for leafy vegetables. In this context, Feltrim et al (2006) reported that lower amplitudes may provide better escarole development, justifying results observed for growing periods.…”

The objective of this study was to determine the base temperature of escarole and to apply in the phenological analysis of crop during four growing periods. The study was carried out with escarole (Chicorium endivia) ‘Escarola Lisa’ cultivar, at the Federal University of Santa Maria, campus Frederico Westphalen-RS. The experiment was performed in a randomized block design with four sowing periods (P1: 2/15/2015; P2: 04/29/2015, P3: 07/22/2015, P4: 10/16/2015) and 10 replicates, each replicate being one plant. The evaluations consisted of counting the number of leaves, performed three times a week after transplanting date until the harvesting point. To determine the base temperature, the following methods were used: standard deviation in degree-days (SDgd), standard deviation in days (SDd), coefficient of variation in degree-days (CVgd), coefficient of variation in days (CVd), regression coefficient (RC) and X-intercept. The base temperature for emission of two successive leaves in the escarole is 4.7°C, obtained by values of 4.0 and 5.5°C, observed in the SDgd and RC methods. For two leaves emission, the temperature between 16.6 and 27.8°C day leaf-1 is necessary.

“…Temperatures below 8°C soon after transplanting increase escarole cycle, however, temperatures above 40°C negatively affect to crop (SÁ; REGHIN, 2008), because acceleration in metabolism results in less accumulation by plants. From this aspect, it can be inferred that the average temperatures observed at these seasons may have been adequate to provide plants with greater photosynthetic area, and consequently greater photoassimilated production and translocation, resulting in greater growth and development , ending the cycle more quickly.…”

The lack of research about escarole cultivars adapted to each region, as well as technical information on plant growth have been some of the factors related to low yields. Therefore, the aim of this work was to evaluate the growth of escarole crop in four seasons of year in Santa Maria, RS. The experiment was conducted in a randomized complete block design, 1 x 4, being a escarole (cultivar Escorola Lisa®) evaluated in four seasons of year (summer, autumn, winter and spring), in six replications. The evaluations were performed in a destructive manner every seven days, from date of transplant to harvest point. The following components were analyzed: number of leaves, number of residues, dry mass of leaves, dry mass of leaves, stem and residue. Thus, it was determined the parameters for growth analysis. With the data obtained, we performed a variance analysis, and presented significant results, and the means of each season of the year submitted to the Tukey test at 5% of error probability. The air temperature and global radiation influence crop cycle. Lower temperatures and lower incidence of radiation result in cycle extended, as observed in autumn. The escarole growth is influenced by seasons of year in Rio Grande do Sul (RS), and summer and spring finish the cycle in advance to others, presenting a larger leaf area. Summer and spring are most indicated season to escarole crop in RS, Brazil. Key words: Chicorium endivia. Spring. Summer. ResumoA falta de pesquisas sobre cultivares de chicória adaptadas a cada região, bem como informações técnicas sobre seu crescimento, tem sido alguns dos fatores relacionados a baixos rendimentos. Diante disso, o objetivo deste trabalho foi avaliar o crescimento da cultura da Chicória em quatro estações do ano em Santa Maria-RS. O experimento foi conduzido em delineamento de blocos ao acaso, 1 x 4, sendo uma cultivar de chicória (cultivar Escorola Lisa®) avaliada em quatro estações do ano (verão, outono, inverno e primavera), com seis repetições. As avaliações foram realizadas de forma destrutiva a cada sete dias, a partir da data do transplantio até o ponto de colheita. Analisaram-se os seguintes componentes: número de folhas, número de restos, massa seca de discos, massa seca de folhas, caule e restos. Com os dados obtidos procedeu-se análise de variância, e apresentando resultados significativos, e as médias de cada estação do ano submetidas ao teste de Tukey a 5% de probabilidade de erro. A temperatura do ar e a radiação global apresentaram influência sobre o ciclo da cultura. Temperaturas mais baixas e menor incidência de radiação resultaram no maior ciclo da cultura, observado no outono.
