| Abstract | ||
| Two field experiments were conducted, followed by two storage experiments of heads, on the red cabbage, to study the impact of spraying some microelements (iron, zinc, and boron), some plant bio-stimulants (seaweed extract and chitosan) and a combination between them on some chemical constituents, yield, and quality (in a complete randomized block design) as well as the storage ability of heads (in a two-way randomized complete design). Obtained results showed the significant superiority of red cabbage plants sprayed with all studied materials compared to the control treatment in the measured characteristics, i.e., N, P, K, Fe, Zn, B, dry matter, quality attributes, number and weight of outer leaves, head height, head diameter, head weight, and total yield/feddan. Plants treated with seaweed extract + chitosan + element mixture significantly gave the highest values of all studied parameters, except NO3-N content. Concerning the effect of the storage experiment, the heads wrapped with light polyethylene significantly gave the superiority in crude protein, total carbohydrates, TSS, total sugars, vitamin C content and anthocyanin. Moreover, these wrapped heads were the least in weight loss in both seasons. In this concern, seaweed extract + chitosan + element mixture along with wrapping harvested heads with light polyethylene gave the maximum storage ability. Thus, it could be recommended that spraying red cabbage with seaweed extract + chitosan + element mixture gave the highest values for characteristics of yield, quality, and storage ability when such treatment was combined with wrapping heads with light polyethylene. | ||
