Other claims from this paper (13)
- Observation Annual mean seed yields were 98.0, 107.7, 179.3 and 265.5 kg hm−2 for W0, W1, W2 and W3.
- Association Seed yield fell in successive years across all irrigation treatments.
- Observation Yearly variation in seed yield was highest under W0 and lowest under W3.
- Association Relative to 2019, W0 seed yield fell by 47% in 2020 and 66% in 2021.
- Association Relative to 2019, W3 seed yield fell by 8% in 2020 and 19% in 2021.
- Intervention effect W3 had two to three times as many florets and pods per stem as W0.
- Association Pods per stem had the largest direct positive modeled effect on seed yield.
- Association Seeds per pod had a positive modeled effect on seed yield.
- Association Germination percentage and seed size increased with irrigation frequency.
- Observation Water use efficiency was similar under W0 and W3.
- Observation W1 had the lowest water use efficiency.
- Recommendation The authors recommend W3 to improve seed yield and quality in arid regions.
- Recommendation Breeding and agronomy should emphasize increasing pods per stem.
