Abstract
In recent years, there has been a marked increase in the consumption of fresh jalapeños used in the Southwetern ethnic food products or Mexican cuisine in United States.
Our objective was to determine how stand establishment methods, cultivar, and in-row spacing affect fruit yield and size of jalapeño peppers.
Experiments were conducted in Uvalde, Texas, during spring 1993 and 1994. Stand establishment methods were (1) transplants grown with overhead irrigation in Texas (TR-TX) and (2) transplants grown with floatation irrigation in Florida (TR-FL) and (3) direct seeding.
Two multiple virus resistant genotypes were used; ‘TAM Mild Jalapeño-1’ and ‘Veracruz’. In-row plant spacings were 10, 20 and 30 cm.
In 1993, the number of normal seedlings unaffected by transplant shock was significantly higher for TR-FL (87%) than for TR-TX (77%), but total green fruit yields were similar.
Transplants had significantly higher total average yields (17.2 MT/ha) than direct-seeded plants (5.5 MT/ha). Similar trends were measured in 1994. Fruit size progressively decreased in later harvests.
Overall, ‘Veracruz’ had the highest yields in both years and total yields decreased linearly with increased plant spacing.
