Processing Tomatoes

The effect of potassium fertilization on blotchy ripening in processing tomatoes (Lycopersicon esculentum Mill.) was investigated. Potassium treatments up to 624 and 590 kg ha−1 in 1983 and 1984 decreased the incidence of blotchy fruit. Differences in blotch susceptibility occurred among commercial cultivars. Potassium fertilization and cultivar are factors influencing pericarp color in processing tomatoes.Key words: Tomato, blotchy ripening, potassium

Potassium Fertilization

Two insecticidal spray frequencies, 0 and 3x per week, against the sweetpotato whitefly, Bemisia tabaci Gennadius, were evaluated at three K rates, 190, 380 and 760 kg.ha-1, for their effect on whitefly population, fruit yield and incidence of irregular ripening on tomato, Lycopersicon esculentum Mill., cv. Sunny. Whitefly populations were reduced with three weekly sprays, but not by K rates. Early yields were best with three weekly sprays and with the highest K rate. For the season, yield of extra large (≥ 70 mm diameter) fruit was reduced with three weekly sprays and with increasing K rates. Proportions of irregularly ripened fruits were similar with either spray frequency, but were reduced at the highest K rate.
