Other claims from this paper (11)
- Intervention effect The dry condition with a water deficit of 168.9 mm during the growing period was the main factor significantly impeding hemp morphological development and fiber yields.
- Intervention effect Control treatments with a precipitation sum of 242 mm at lower planting density had significantly taller hemp plants (122 cm on average) than simulated water-scarce dry treatments.
- Intervention effect Control treatments with a precipitation sum of 242 mm at lower planting density had greater total biomass yield (3.74 t/ha dry weight) than simulated water-scarce dry treatments.
- Intervention effect Simulated water-scarce dry treatments planted in high density gave the lowest plant height (69 cm).
- Intervention effect Dry conditions prompted nitrogen accumulation up to 35 N g/kg in hemp biomass despite low soil N.
- Intervention effect Dry conditions prompted nitrogen accumulation of 18 N g/kg in hemp lateral roots.
- Intervention effect Dry conditions prompted nitrogen accumulation of 13 N g/kg in hemp tap roots.
- Observation High calcium content was found in hemp biomass and lateral roots.
- Observation Potassium content was greater in hemp tap roots.
- Observation Elemental analysis showed that hemp parts contain considerable amounts of macronutrients.
- Recommendation A lower hemp planting density should be considered for hemp cultivation in a water-scarce and nutrient-deficient environment.
