| Abstract | ||||
| Two field trials were conducted on garlic clone Sids·40, in Ihe vegetable private farm at Kafr Meet Faris, Oakahlia Governorate. during 2000/2001 and 200112002 seasons to study the effect of application methods of K·fertilizer (soil application. folfar application and 50% soil application + foliar), either single andlor in combination with mixed of mlcronutnents (Fe, Ze and Mn) at 0, 150 and 300 ppm as a foliar application at 60, 90 days after planting on plant growth, yield and its components. as well as chemical constituents and storabiUty of bulbs. Almost all the parameters of the garlic plants received K·fertilizer as a 50% soil application + foliar application significantly increased as compared with other application methods. Beslde~. the most interesting observation was the increasing of the slarability by application KJO as 50% soil application + foliar application followed by soil apptlcatlon In both seasons. On the other hand, foliar application of micronutrlent at 300 ppm caused significant increases in plant height, number of leaves, shoot dry weight and bulblng ratio as well as total yield and bulb weight and diameter. Moreover, this treatment significantty Increased COncentration of TSS, N. p, K and micronutrients (Fe, Zn and Mn) in cloves comparing with those of the plants of the other treatments. However, weight loss percent of bulbs was signiflcanlty reduced during the storage period at 90 and 120 days. The combined treatments of K20 app/lw.tion methods and micronutrients levels were generalty more offective than with single ones. The best results were obtained by using ~O as 50% soil application + foliar applicatlon with foliar application of micronutnents at 300 ppm. Therefore, this treatment could be recommended for raising gariic yield and improving bulb quality during the storage period as well as lowering the productive cost under similar conditions to this work. | ||||
