Fair. I just edited my comment because I combined two concepts and muddled them together. It's more common to suffer a poorer yield than total crop loss. But crops like tomatoes can die from lack of water during high heat days if the heat lasts for several days. Also, irrigating only at night (not just evening, but over night) can contribute to fungal and disease issues with some crops.
- Jedd 3y agoSure, cucurbits and solanaceous crops and prone to humidity / water induced fungal attacks. Tomatoes are better watered at ground level (refer other thread about drippers) or even just flood irrigation. Tomatoes are actually pretty robust, if you grow them properly. The way I was taught to maximise survival / yield in hot climates is to grow as seedlings for a few weeks, until they're maybe 30cm or so tall. Dig holes ~ 25cm deep, flood / drain / flood / drain - and then take all but the upper few branches off the seedling, and plant, backfill with soil, so about 5m is above-ground. Because they have adventitious rooting you've effectively just given them a massive reservoir of water retention. This is obviously expensive at scale (though not intrinsically infeasible) but works superbly well in hostile, arid climates. I expect the next decade or two will force a lot of changes to the way food is grow in already marginal climates.
