Abstract

In organic horticultural systems, cover crops could provide several ecological services, therefore, they can be defined agroecological service crops (ASCs). The objective of this two-year research was to study the suitability on melon production of different ASC termination strategies, in combination with organic fertilisers application. In a split-block design, the main-plot was the ASC management, comparing: i) green manure, in which the vetch was chopped and plowed into the soil; and ii) roller-crimper (RC), in which the vetch was flattened by a roller-crimper; with iii) fallow control, without vetch. The subplot consisted of offfarm organic inputs: i) commercial humified fertiliser; ii) anaerobic digestate fertiliser; iii) composted municipal solid wastes; which were compared to iv) unfertilised control (N0). At vetch termination, above soil biomass and nitrogen (N) content were determined. At harvesting, crop yield performance and quality, N status and N efficiency were investigated. Also, main soil characteristics were assessed at the end of the trial. Among the ASC managements, the slightly reduced yield in the RC plots particularly in combination with N0 might have been the result of less N supplied by the vetch during the melon cycle. Anyway, no negative effects were observed for yield quality. The use of the RC showed a great potential in enhancing soil fertility. Our study suggests the suitability in organic farming of properly matching management of ASC and fertilisation strategies on melon crop.

PlumX Metrics

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
