Growth and Yield Potential of Green Pepper as Affected by Nitrogen at Transplanting
Hassan, Siti Aishah and J. M., Gerber and W. E., Splittstoesser (1993) Growth and Yield Potential of Green Pepper as Affected by Nitrogen at Transplanting. Pertanika Journal of Tropical Agricultural Science, 16 (2). pp. 101-105. ISSN 0126-6128
Green pepper (Capsicum annuum L. cv. Lady Bell) was grown for 7 weeks and transplanted into the field. The following rates of N were applied: 112, 224, 336 and 448 kg/ha. High N rates at transplanting did not stimulate vegetative growth but suppressed plant growth, particularly during the early growing period. As N rates increased, plants exhibited poor early growth and produced lower early and total fruit yields. Early yield positively correlated with plant dry weight. Doubling the N rate from 112 to 224 kg/ha resulted in a 21% increase in flower buds, but the percentage of fruit set decreased as N rates increased. Fruit set correlated negatively with total leaf N and positively with plant weight, suggesting that a high leaf N content and a lower plant weight were detrimental to fruit set and yield of green pepper.
