It looks like rice but the next section has what looks like maize/corn : wouldn't think of those as companions. Interesting that there are quite a lot of Pinus in the area probably to stabalise and avoid salinity. Nothing much grows well under pines due to the chemicals released from needles ;somewhat like Eucalypts, Corymbias & Cinamomon sp. etc, but as they are sentinel like ,dont thake up much ground space. It is a shame that in 100 years of farming we have done more damage to the planet using chemicals (fertilizer etc) than the previous 1000's years using manures & hand work.
