Effect of Spraying Some Microelements and Bio-Stimulants on Yield, Quality and Storage Ability of Red Cabbage Heads

Abstract

T WO 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 NO 3 -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.

The Impact of Seaweed Extract and Biofertilizer on Root Growth and some Mineral Content of Orange Seedlings

“…Biostimulants are substances, whether natural or artificial, that are used to enhance the growth of seeds, plants, and soil. The existence of these chemicals leads to changes in both crucial and architectural activities, which subsequently impact the growth of plants by augmenting cellular metabolism [10,11]. Bio fertilizers are advanced agricultural technologies that involve the application of preparations containing microorganisms to seeds, plants, soil, or a combination of these.…”

Impact of Organic Fertilization and some Beneficial Elements on the Performance and Storability of Salt-Stressed Crisphead Lettuce (Lactuca sativa L.)

“…especially the hot one, causes severe loss of its quality. According to Pinto and Morais (2000) and Doklega and Abd El-Hady (2023), the leafy vegetables after harvest are subject to continuous biological changes as respiration, transpiration and ethylene production, which may be desirable or undesirable. Some treatments, including low temperature storage with 1-MCP (Jiang et al, 2014), UV-C (Costa et al, 2006), hydro-cooling (Finger et al, 2018) and cold storage (Schmitz et al, 2019) were previously adopted to prevent quality decline of iceberg lettuce and other vegetables during storage.…”
