The temperature is one of the climatic factors of greater importance in the physiological processes of the plants, being directly related to its growth and development, which need a thermal accumulation to complete its phenological cycles. The objective of this work was to evaluate the contribution of temperature to cacao tree seedlings (genotype TSH1188) development, thus determining its lower basal (Tb) and upper (TB) temperature as well as the thermal sum in degree-day (DD) required for its production with quality. The study was carried out in the Horticulture sector of the Federal Institute of Espirito Santo - Campus Itapina, Colatina/ES, conducted under a completely randomized design in three planting seasons with different climatic conditions. For the estimation of Tb, four different estimation methods were used: standard deviation in degree-day (SDdd), the standard deviation in days (SDd), the coefficient of variation in degree-day (CVdd) and relative development (RD). The upper basal temperature (TB) was estimated similarly to Tb, with the exception of the RD method. The basal temperatures (Tb and TB) were estimated by means of the average values obtained in the methods used and the thermal sum, obtained in each planting season, using the mean Tb value, from the emergence of the seedlings, by the sum of the degree-days. The estimated values of lower and upper basal temperature were respectively 10°C and 37°C and the mean thermal sum for a quality cacao tree seedling production is 1018°C. In order to obtain a production of quality cacao tree seedlings in different climatic conditions, it is possible to evaluate the development of the variables height, stem diameter and number of leaves of the cacao tree seedlings as a function of accumulated degrees. The time required for the production of cacao tree seedlings varies according to the season of the year. Cacao tree seedlings conducted in periods with higher temperatures took less time to form with quality.

O estudo de custo de produção apresentado neste capítulo contempla dez espécies de hortaliças utilizando-se a base de dados de 20 anos da Unidade de Referência em Agroecologia do Incaper, de 1990 a 2009. Relata-se que o sistema orgânico confirmou grande viabilidade econômica, com média de custo de produção por hectare 8% menor que a média das hortaliças convencionais. O gasto com mão de obra foi ligeiramente menor no sistema orgânico e confirmou ser o componente de maior participação nos custos de ambos os sistemas. Os sistemas orgânicos de abóbora, morango, repolho e tomate apresentaram custo de produção menor que os convencionais. Por outro lado, os sistemas convencionais de alho, batata e quiabo apresentaram custo de produção menor que os orgânicos. Já as culturas de cenoura, pimentão e taro mostraram valores semelhantes em ambos os sistemas. As receitas líquidas de todas as culturas olerícolas no cultivo orgânico foram superiores às obtidas no cultivo convencional das respectivas espécies. |
