| Abstract | ||||
| In Egypt, garlic is of great importance in the agricultural and commercial sectors. Therefore, improving its quantitative and qualitative characteristics, especially under water deficit challenges, will have a significant positive impact on food production and the agricultural economy. So, afield experiment was carried out during two successive seasons to evaluate the effect of three irrigation requirement treatments [100,80 and 60% of Irrigation Requirements IR] as main factor, three potassium silicate rates [0.0 5.0 and 7.0 kg fed-1] as sub main factor and two treatments of calcium/boron mix [applied or not] as sub sub plots on the quantitative and qualitative traits of garlic. 100% of IR achieved the highest values of most parameters e.g., plant height, No. of leaves plant-1, carotene, marketable bulb yield, TSS, vitamin C, followed by 80% and 60%, respectively. As the potassium, silicate rate increased the values of most traits increased, where the 7.0 kg fed-1 treatment led to the best results. In contrast, the calcium/boron foliar application showed no significant individual effect on some parameters such as neck diameter, vitamin C and showed a positive significant effect on other traits such as average bulb weight, bulb diameter, total and marketable bulb. As for interaction, there aren’t significant difference in the effect between the combined treatment [80 % IR x potassium silicate (7.0 kg fed-1) x Ca/B] and the treatment that combined 100% IR with no potassium silicate and no Ca/B application. Therefore, this approach can be incorporated into garlic cultivation, especially under water deficit conditions. | ||||
