Effects of excess nitrogen on growth, flowering and fruit set of bell pepper (Capsicum annuum L.)

Field experiments were conducted on a Flanagan Silty Clay Loam to investigate the influence of excess N at transplanting a growth, yield and fruit set of bell pepper (Capsicum annuum L. cv. 'Lady Bell'). The rates were 112, 224, 336 and 448 kg N/ha. Excess N at transplanting did not stimulate vegetative growth, but rather suppressed plant growth, particularly at early growing period. In general, plants exhibiting poor early growth produced lower early and total fruit yield. Excess N (336 and 448 kg N/ha) reduced the total number of fruits per plant by as much as 48 to 57% at early harvests. The percentage of fruit set decreased linearly as N rates were increased. Fruit set was correlated negatively with total leaf N and positively with plant weight, suggesting that higher leaf N content and lower weight of plant grown with excess N were detrimental to fruit set and yield of bell pepper.
