| Abstract | ||
| Two field trials were conducted on garlic clone Sids-40, in the vegetable private farm at Kafr Meet Faris, Dakahlia Governorate, during 2001/2002 and 200212003 seasons to study the effect of some potassium-fertilizer levels at 0, 24, 48, 72 or 96 kg K20/fed, mepiquat chloride (pix) at 0, 250 and 500 ppm as a foliar application and their interactions on the plant growth, yield and its quality as well as chemical constituents of plant foliage and bulbs. Results showed that garlic plants received K-Ievels better than those of the unfertilized ones. most studied characteristics of garlic plants were significantly increased with increasing K-Ievels from 0 up to 96 kg K20/fed. Besides, the most interesting observation was the increasing of the yield and its components by 96 kg K20/fed in both seasons. Moreover, this treatment significantly increased concentration of N, P, K, TSS and volatile oils in cloves comparing with those of the other treatments. On the other hand, foliar application of pix at 250 or 500 ppm significantly reduced plant height. However, increasing the applied pix level from 0 up to 500 ppm significantly increased number of leaves, leaf area, plant dry weight and bulbing ratio as well as total yield, bulb weight and diameter and clove weight. The combined treatments of K20 levels and pix were generally more effective than with single ones. The best results were obtained by using 96 kg K20/fed with foliar application of pix at 500 ppm. Therefore, this treatment could be recommended for raising garlic yield and improving bulb quality under similar conditions to this work. | ||
