Phytotoxicity of foliar-applied urea

Absorption and Mobility of Foliar Applied Nutrients.

Absorption and translocation of foliar-applied iron.

The absorption of (59)Fe(3+) by the leaves of various plant species was studied. Stomata were found to play a major role in foliar absorption when leaves were totally submerged in treatment solutions, and a correlation was found to exist between stomatal area and absorption. Day treated leaves absorbed much more than did night treated leaves. The use of a surfactant markedly increased absorptio...

Assessment of the Slow-Release Nitrogen Foliar Fertilizer Nitamin® in Comparison to Foliar Urea and Soil-Applied Nitrogen to the Yield of Field-Grown Cotton (Gossypium Hirsutum, L.)

Effective nitrogen (N) management in cotton production is essential in order to achieve proper growth and development. However, soil-incorporated N can undergo a series of chemical conversions along with numerous loss mechanisms (leaching, volatilization and denitrification) that can make N unavailable to the plant. In addition, soil-incorporated N has faced much scrutiny over the years for its...

Effects of Rhizobium– Mycorrhizae Symbiosis and Foliar Application of Urea on Some Traits of Soybean

In order to investigate the effect of rhizobium bacteria, mycorrhiza fungi and foliar application of urea on qualitative and quantitative traits of soybean an experiment was conducted based on randomized complete block design with four replications. The experiment included six treatments as: Control (C), Rhizobium bacteria (R), Rhizobium bacteria + Mycorrhiza fungi (R+M), Rhizobium bacteria + F...

Factors Affecting Absorption and Translocation of Foliar Applied Phosphorus.

Phosphorus is known to be exported from leaves of apple (8, 9, 10), bean (4, 6, 11, 12, 13), chrysanthemum (1, 2), corn (11, 12), tomato (12) and squash (71). The present work with bean plants compares export following application by spray, leaf vein injection (4) and droplet (13) methods. Other factors investigated which affect absorption and subsequent translocation of the spray-applied phosp...
