![]() ![]() The experiment was realized to verify the possibility of applying Boron as foliar fertilization with growth regulators: indol acetic acid, giberellic acid, ethephon and cycocel. International Nuclear Information System (INIS) Keywords: Wheat, Growth stages, Boron application time, Water stress, Crop yield, Plant pigments, Proline, H2O2įoliar fertilizations with boron and growth regulators on lettuce (Lactuca sativa L.) cv floresta culture Therefore, booting stage was found to be the best time for boron application to get higher grains production and consequently, better economic returns of wheat. This alleviating effect was more pronounced when B applied at booting stage. The reduction in stress markers (proline and H2O2 and the enhancement of plant pigments content under water stress levels (50% from the amount of water consumption for wheat by B spraying suggests an alleviating effect of boron foliar application to water stress in the test plant. Boron spraying at booting stage enhances also plant pigments contents recording its highest mean values under normal water level (100% from the amount of water consumption for wheat. ![]() Furthermore, boron application significantly enhanced all studied growth traits under water stress levels (50% from the amount of water consumption for wheat compared to B-untreated plants. The highest mean values obtained against boron application time were potential contributor to total grains mass by improving the plant height (99.42 and 98.32 cm, spike length (11.86 and 11.72 cm, number of spikelets m−2 (332.65 and 324.35, grain yield plant−1 (21.56 and 20.26 g, 1000-grain weight (35.2 and 37.4 g and grain yield (1.87 and 1.85 ton fed.−1, which were recorded at normal irrigation level (100% from the amount of water consumption for wheat with boron spraying at booting stage (B1 in the first and second seasons, respectively. Improvement of wheat yield grown under drought stress by boron foliar application at different growth stagesĭirectory of Open Access Journals (Sweden)įull Text Available Two field experiments were conducted to determine the effect of boron foliar application and water stress on yield of wheat plant grown in calcareous soil during 015 seasons. ![]()
