ABSTRACT:
Chilling requirement is a characteristic that limits temperate fruit crops cultivation under a subtropical climate. Several mathematic models have been developed, differing on the relative value of chilling units, in order to estimate the chilling accumulation on a given site. The present work compared eight of these models using data from hourly temperatures from May to August, from a period of 11 years, collected in Pelotas, RS, Brazil, aiming to characterize the region regarding the chilling accumulation for the cultivation of deciduous fruit trees and to check if a model using average temperatures is suitable enough to be used when hourly temperatures were not available. The eight tested models were: Chilling Hours (?7.2°C); Chilling Hours (?11°C); Utah; Low Chill; Dynamic; Mean Temperatures; Positive Utah and Taiwan. The results showed large differences between years, regardless of the model used. However, the Taiwan and Low Chill models seemed more suitable for the estimation of the accumulation of cold in the Pelotas region. The Medium Temperatures model can be used as a valid option since it has a high correlation with the other models and easy data availability.

ABSTRACT - Crop rotation is one of the oldest management strategies in agriculture and has two main purposes: plant nutrition and management of weeds, pests, and diseases, particularly soilborne diseases. Not only is it a long-term strategy for organic agriculture, it is a strong recommendation and a requirement in some countries. One of the consequences of crop rotation in farming systems is the mosaic of crops at farm and landscape levels. With an increasing number of crops in a rotation, the fields on a particular farm usually become smaller. This increases the agrobiodiversity at the landscape level. The size and complexity of the mosaics in space and time have a tremendous influence on the development of plant disease epidemics and pests. Here, we focus on the temporal variation in crops and its consequences for plant disease development. The succession of a variety of crops can affect both foliar and root diseases. The effects on foliar diseases are, however, primarily determined by the spatial pattern in crops, especially when pathogen inoculum is spread over medium or large distances. We limit this chapter to effects on soilborne pathogens with local inoculum spread; this includes splash-dispersed soilborne pathogens that affect the lower stem and foliage as well as root-infecting pathogens. |
