The impact of various foliar concentrations of urea in some physiological characteristics and characeristics of fruit and stomata frequency to leaf pepper Capsicum annuum L.

Abstract

This experiment was conducted at the Faculty of Agriculture / University of Anbar - Department gardening wooden canopy for the agricultural season 2010 for the purpose of knowing the effect of foliar nutrition urea concentrations 0, 0.5, 1 and 8 g / liter of D.W on the plant pepper Capiscum annuum L. , Study results showed that foliar with concentration 0.5 g led to outweigh the moral in the rate of total chlorophyll (4.95)mg/ g while reducing rate of chlorophyll when concentration 8 g to (4.44)mg/ g as indicated results that a higher percentage of the content of the leaves of the nitrogen was in the transaction R3 (4.05) and for the aerea surface of leave recorded the treatment R2 highest rate (77.2cm²), while the lowest rate for the area of leave within the treatment R3 (46cm²) show clearly distinguishes the treatment R1 (21.39g) in the qualities of fruits and productivity and the level of moral and clear while it was lowest the rate of productivity in the treatment R3 (11.38g) also showed results distinguish the two treatments R1 and R2 (8.20) and (7.99) in the stomata frequency for upper and lower epidermis compared with the treatment R3 (6.03) as shown by the results that foliar urea effect in plants treated R1 in the average length of the cells to the surface of fruits(105 um) and recorded to the treatment R3 (48.7 um) the lowest rate in the length of the cells.
