Growth and Yield of Some Jew's Mallow (Corchorus olitorius L.) Ecotypes as Affected by Planting Dates and Foliar Application of Gibberellic and Humic Acids

Abstract

A Field experiment was conducted in 2015 and 2016 cropping seasons at the Vegetable Crops Research Station, Faculty of Agriculture, Assiut University, to study the response of three Jew's Mallow Ecotypess (Assiut, Eskandarany and Aswan) to planting dates and foliar application of Gibberellic acid (GA3) and Humic acids (HA) treatments. The Jew's Mallow ecotypes were planted on 15 th Feb. and 15 th Oct. in both cropping seasons and subjected to three foliar applications of 0.25mg.l -1 GA 3 (T1), 0.5mg.l -1 HA (T2) and 0.5mg.l -1 HA + 0.25mg.l -1 GA 3 (T3) and untreated plants were used as control. The results revealed that the Jew's Mallow ecotype 'Assiut' attained the highest plant (cm), number of leaves/plant, weight of leaves/plant(g), weight of plant (g), percentage net weight of leaves/plant and foliage yield (kg.plot -1 ) in both seasons. The early planting date (15 Feb.) extremely increased growth, yield components and yield parameters in 2015 and 2016. Foliar application of gibberellic acid (GA 3 ) at 0.25mgl -1 (T1) significantly increased growth and yield of Jew's Mallow plants. Spraying plants of the Jew's Mallow ecotype 'Assiut' with GA 3 at 0.25 mg.l -1 at planting date 15 th Feb. significantly increased growth, yield components and yield parameters in both seasons.

Unveiling the Chemical Composition, Bioactive Profile and Antioxidant Capacity of Dried Egyptian Jew’s Mallow Stems as a Promising Anticancer Agent

“…Figure 1 displays the primary significance of the nutrient composition and estimated energy value, presented in terms of dry weight. The obtained results show that mallow has a high content of protein, carbohydrate, fat, and ash (20.22, 57.00, 2.86 and 17.84%) in dried stems compared to dried leaves, which ranged between 10.44 and 36.73% for protein, 46.07% for carbohydrate, 1.7 for fat and 7 and 16.13% for ash [ 31 , 32 , 33 ]. Fat was the least prevalent, with a macronutrient abundance of less than 3%.…”

Detection and Molecular Characterization of Phytoplasma and its Effect on the Vitamin and Fibers in Corchorus olitorius Crops in Egypt

“…The mallow (molokhia) plants (Corchorus olitorius L.), also known as Jew's mallow, wild okra, jute mallow, or tossa jute, are primarily herbaceous perennials from edible leafy vegetables or fiber crop in the Malvaceae family and present naturally in the Mediterranean (Cagirgan et al, 2014;Abdel-Razek et al, 2022). With a 2.45tons/ha productivity, Egypt's 887 hectares of jute mallow farming produced about 2173 tonnes of output (Haridy et al, 2019). Studies have shown that this plant plays a relevant role in maintaining human health, and the plant possesses a wide range of biological activities connected to its phytochemical composition (Moerman, 1996;Hussien et al, 2017;Abdel-Razek et al, 2022) as the leaves of C. olitorius include minerals, vitamins, and phenolic compounds that are abundant in plants (Schipper, 2000;Abdel-Razek et al, 2022).…”

Methane production from anaerobic co-digestion of primary sludge and crop residues under mesophilic condition

“…As well as, corchorus is an extremely popular Egyptian green vegetable. About 887 hectares is cultivated by Corchorus in Egypt and its total production is about 2173 tons (Abbas and Mousa, 2019). From the point of view of economic development and environmental protection, diverting organic wastes such as sewage sludge and crop residues to get values from them, such as energy production, is essential.…”
