I am proposing "crop" as I am creating wikidata items for describing long-term agricultural experiments and wish to document the crops grown for the experiment. In my use case, crops would winter wheat, potatoes, spring beans, oats and maize. I would expect this to be a general property for other agricultural items, therefore suggesting this is constrained to field (Q188869), agricultural experiment (Q52146473) and farm (Q131596) and subclasses.
It should be possible to optionally qualify the crop with 1 or more cultivars.  – The preceding unsigned comment was added by Richardostler (talk • contribs) at 10:04, April 24, 2018‎ (UTC).

  • Symbol support vote.svg Support seems reasonable. Have you considered making it more general (e.g. "produce")? --99of9 (talk) 02:17, 1 May 2018 (UTC)
@99of9: Thanks for the support and comment. Crop could also include a cover crop, or a break crop including grasses in a ley-arable rotation. I can't think of a broader term. Produce wouldn't be appropriate for these, but they could be defined as subclasses of crop. In the agricultural context produce may be better defined as the harvested material, including from livestock, e.g. grain, fruit, tubers, haylage, eggs, flowers, milk, meat.--Richardostler (talk) 09:32, 1 May 2018 (UTC)
Let's suppose there was a long term experiment which evaluated how much wool was produced under different scenarios. Couldn't we find a way to use the same property to link the experiment to wool? --99of9 (talk) 04:08, 7 May 2018 (UTC)
On reflection, in my opinion this is too narrow to support. --99of9 (talk) 06:27, 26 June 2018 (UTC)

@Gstupp: Thanks for your feedback, but can you please elaborate on your objection? I think natural product of taxon (P1582) would work if I wanted to describe the product (e.g. grain) of the crop grown on the field, but that isn't the aim. The aim is to simply document the crop i.e winter wheat, grown on the experiment field, or any agricultural field. I think this proposed crop property is therefore aligned with AGROVOC crops concept.--Richardostler (talk) 16:06, 1 May 2018 (UTC)
Sorry I misread the proposal. Any ways, this still seems oddly specific. Is there a way we can make it apply to any scientific experiment? I'm thinking specifically in how this could be used in a clinical trial for example. How about the property uses (P2283) and qualify it with object has role (P3831) -> crop (Q235352) ?

  • Symbol oppose vote.svg Oppose This is really too specific. Have you considered uses (P2283) for experiments? I think it's two things - one is a species USED in an experiment, and the other is species GROWING somewhere. While the first case can be easily modelled in the current structure, the second will probably require some property in future (which will be also applicable to stuff like meadows, groups of trees etc).--Vojtěch Dostál (talk) 06:58, 31 May 2018 (UTC)
