Yield and quality of lemongrass plants (Cymbopogon flexuous Stapf) as influenced by farm yard manure and foliar application of bread yeast [electronic resource].

Includes references.

Two field experiments were carried out at the National Research Center, Giza, during the two successive seasons of 1999 and 2000 to evaluate the influence of farm yard manure (FYM) and foliar application of bread yeast (Y) solely or in combination, on the vegetative growth, yield, productivity and oil quality of lemongraSS plants (Cymbopogon flexuous Stapf). Appreciable effects of varions treatments were identified from all of the studied characters through the two cuts during both growing seasons. Spraying plants with bread yeast gave higher values for all characters than those obtained from the treatments of FYM. The most pronounced increments in height, number of tillers, yield, as well as, essential oil percentages, the content of (Citral A and Citral B), chlorophylls, carotenoids, total carbohydrates and NPK content and up take, resulted from the combination of FYM combined with bread yeast. The same trend of results were observed during both seasons and through the two cuts. To obtain highest yield with high quality of lemongraSS oil.
