Intervention effect Potassium application raised income by 4.4% to 16.5%, averaging 9.5%, below 450 kg/hm2.
Observation The 300 kg/hm2 K2O rate produced the highest capsicum yield and income.
Intervention effect Potassium application increased vitamin C content in edible capsicum parts with increasing rates.
Intervention effect Proper potassium application increased capsicum fruit length by 5.1%.
Intervention effect Proper potassium application increased capsicum fruit thickness by 13.7%.
Intervention effect Proper potassium application significantly increased potassium uptake in capsicum fruit, stem and leaf.
Observation Potassium uptake in capsicum followed a fruit, stem, leaf ranking.
Observation The highest agronomic efficiency was 31.7 kg/kg at 300 kg/hm2 K2O.
Recommendation The authors recommended about 300 kg/hm2 K2O for capsicum under medium soil fertility in Hainan.

NITROGEN CONCENTRATIONS TO MAXIMIZE YIELD AND DECREASE LEACHATE-N IN PEPPERS GROWN IN ROCKWOOL.

M.K. Schon; M.S. Compton; I. Burns; et al. HortScience 1993. doi:10.21273/hortsci.28.5.507a

Other claims from this paper (6)

Intervention effect Increasing N did not affect the number of marketable pepper fruit in Trial 1.
Intervention effect Increasing N increased the size of pepper fruit in Trial 1.
Intervention effect Marketable yield did not differ significantly between 120 ppm N and 175 ppm N.
Intervention effect Nitrogen level did not affect blossom end rot occurrence in peppers.
Association Higher N concentration was associated with a higher occurrence of blossom end rot in early Trial 2 results.
Recommendation The authors recommend 120 ppm N to maximize yield and reduce environmental impact of greenhouse pepper production in Florida.
