Other claims from this paper (10)
- Intervention effect Optimal KCl fertilization increased the biomass and vegetation index of garlic.
- Intervention effect Optimal KCl fertilization promoted the transfer of nitrogen, phosphorus and potassium from stem and leaf to bulb.
- Intervention effect Optimal KCl fertilization increased bulb production in garlic.
- Intervention effect KCl fertilizer increased the number of cloves and the diameters of cloves and bulbs of garlic.
- Intervention effect KCl fertilizer reduced the variation in bulb size of garlic.
- Intervention effect KCl fertilizer improved the nutritional quality of garlic, including vitamin C, soluble sugar, soluble protein and allicin.
- Intervention effect KCl fertilizer reduced the accumulation of nitrate in garlic.
- Intervention effect K 2 SO 4 applied alone increased garlic yield by only 0.1% to 22.5% compared with KCl, and the results were not always significant.
- Intervention effect A K 2 SO 4 to KCl ratio of 3:1 gave the highest garlic yields, appearance traits and nutritional quality.
- Recommendation The authors recommend a potassium fertilizer rate of 252.5 kg ha-1 K2O, with K2SO4 accounting for 61.6%, for garlic production in the field.
