Abstract
In the context of the current climate change, it has become urgently necessary to develop adequate systems to protect horticultural crops. In Romania, the losses caused to these cultures by the extreme weather phenomena, as well as the lack of active intervention measures to combat or limit them, represent the main argument for addressing this field in particular. Vegetable crops are generally sensitive to extreme weather phenomena. In the climatic conditions in our country, the extreme phenomena occur between March and September, which coincides with the vegetation period of the crops. Of these, hail causes significant damage, and in some cases, at high intensity and long-lasting, can cause the calamity of vegetable crops. Another effect can arise in the drought years, when, in the absence of rainfall, the weeds enter into a fierce competition with vegetables, as regards the specific consumption of water and nutrients. The paper presents a review regarding the current methods of vegetable crops protection against the extreme weather phenomena and of weed control in these crops, grown in organic system. Combining the available solutions, adopting integrated strategies for non-chemical weed control can be an important premise for researchers and farmers to protect vegetable crops.
Highlights
An increasing importance has been given to the study of climate change, due to the negative effects generated on natural ecosystems, human health and the economy
The purpose of the paper is a presentation of the current state of protection methods against the negative effects caused by climate change for organic vegetable crops
Since vegetable crops in ecological system fall into the minor crops, we present a nonchemical weed control strategy proposed for them [26]
Summary
An increasing importance has been given to the study of climate change, due to the negative effects generated on natural ecosystems, human health and the economy. The global warming, manifested by the increase in average and extreme temperatures of the air has been demonstrated by numerous studies carried out in different regions of the globe, during several decades [1, 2, 3, 4]. This has resulted in an increase in the humidity level of the atmosphere, increasing the intensity and frequency of negative events related to extreme precipitation, which is one of the most variable climatic elements [5]. The purpose of the paper is a presentation of the current state of protection methods against the negative effects caused by climate change for organic vegetable crops
