Abstract
This study was carried out at private farm under clay soil at Shoubra belola, Kotour. Gharbia Govemorate, Egypt during the two successive winter seasons of 2007- 2008 and 2008-2009. The aim of this study was to evaluate the effect of humic acid, sulphur, different application methods of potassium fertilizer and their combinations on the growth, yield, quality and storability of garlic (cv. Balady).
Treatments used:
This experiment included 24 treatments, which were the combinations between two levels of humic acid, three levels of sulphur and four levels of potassium as follows:
The humic acid (HA) treatments were:
1. Control (without humic acid) 2. 5 kg / fed. (Soil application)
The sulphur (S) treatments were:
1. Control (without sulphur).
2. 100 kgS/fed.
3. 150kgS/fed.
The potassium (K) treatments were:
1. 96 kg K2O /fed. (Soil dressing) as a recommended dose (control)(K 1).
2. 48 kg K20 /fed. (Soil dressing) + 1% KzO (Foliar application)(K2).
3. 48 kg K2O /fed. (Soil dressing) + 2% KzO (Foliar application)(K3).
4. 48 kg K2O /fed. (Soil dressing) + 3% K^O (Foliar application)(K4).
These treatments were arranged in a split split -plot design with three replications. The humic acid levels were in the main plots, the sulphur levels were randomly arranged in the sub main plots and the potassium fertilizer levels were randomly distributed in the sub sub main plots. The study included vegetative growth, yield and yield components, chemical constituents and storability.
