| Abstract | ||||
| Growth of wheat plants cv. Sakha 93 was significantly enhanced during 2003/04 and 2004/05 seasons by application of the natural yeast and garlic extracts (YE and GE) each at 50 and 100 ml/l as well as benzyladenine (BA) at 25 and 50 ppm. Since, significant increases in stem length, No. of both tillers and leaves, stems and leaves dry weights and total leaf area / plant were obtained with all applied treatments. Meanwhile, significant reduction in the assimilation rate was existed. Besides, different assigned treatments obviously increased the concentrations of photosynthetic pigments, NPK, crude protein and total carbohydrates in the flag leaf of treated plants as compared to those of untreated ones. In addition, all applied treatments caused positive alterations in many anatomical features of stem and flag leaf blade of treated plants. Among of these, the most important ones, increases of lamina thickness, length and width of vascular bundle and thickness of phloem and xylem tissues. Moreover, different applied treatments significantly improved the total grain yield/plant and its components as well as the straw yield/plant compared with those of untreated plants. The highest grain yield was attained by applying GE at 100 ml/l followed by BA at 50 ppm then YE at 100 ml/l. Hence, the present study strongly admit the use of natural yeast and garlic extracts and benzyladenine not only to improve growth and productivity of wheat plants but also to avoid all cautions (regarding human health) about the use of synthetic growth regulators and the excessive use of mineral nutrients specially on the nutritional crops. | ||||
