“…The feldspar effects due to its role as a potassium source which it activates a lot of physiological process as occur in plant such as maintaining cell organization, cell hydration and permeability. It activates many enzymes system such that occur in protein synthesis and formation of carbohydrates (Nijjar, 1985;Tamim et al, 2000 andAbdel-Rahman, 2010).…”

The current investigation was carried out during 2018 and 2019 seasons to study the effect of some fertilizer practices on yield, fruit quality and some mineral content of Khalas date palm grown in a private farm, Luxor Governorate, Egypt. Results showed that significant improved due to use slow release fertilizers as well as comparing total soluble fertilizers in terms of vegetative growth and nutritional status yield, bunch weight and fruit quality during both seasons. Using 600 g of N and 300 g of K via slow release fertilizers form had improved the growth and nutrient status of date palms as well as increase the fertilization efficiency. Also, it could be suggested that fertilizing by 60 to 75 of RDN and RDK via slow release fertilizers to improve the nutrient status of palm and gave the high bunch weight and consequently high yield/palm. Moreover, these fertilization treatments via slow release form gave high yield with good fruit quality compared with using 100% of RDN and RDK via mineral source during both studied seasons. On the light of previous results, it could be concluded that Fertilizing the palm by 60 to 75% of recommended doses of fertilization via slow release form to get high yield with good fruit quality. In addition, reduce the environmental pollution and increase the fertilization efficiency.

“…Potassium (K) is a mobile element in the plant and is an activator of enzymes that are essential for photosynthesis and respiration as well as enzymes that produce starch and proteins. It also activities enzymes involved in plant growth and improves the fruit quality (Dhillon, 1999;Tamim et al, 2000;Ahmed, 2008 andOsman, 2010).…”

Finding a rich and natural source of potassium nutrient is a major challenge facing banana cultivation. In this study, four different sources of Potassium: potassium sulphate, slow release (feldspar), bio-fertilizer (yeast & potassin) and potassium thiosulphate were used to evaluate their effects on growth & fruit production of Grand Nain banana cultivar grown at Luxor Governorate condition, Egypt. The results indicated that using yeast or feldspar alone or in combination as a source of potassium and potassin significantly increased all growth aspects, yield and fruit quality compared to fertilize by potassium sulphate (check treatment); Moreover, there were insignificant differences in these studied traits due to fertilize with yeast, feldspar alone or in combination as well as spraying potassium thiosulphate or potassin. Using yeast or feldspar plus yeast were very effective in enhancing all growth aspects, yield, bunch traits and fruit characteristics compared to untreated ones; So, it is evident from the foregoing result that using feldspar or yeast alone or in combination improved the growth, nutritional status and fruiting of Grand Nain banana plants;. In addition, they are beneficial in organic farming production since they improve the soil structure and fertility; also, reduce the cost of production and environmental pollution.

“…The incidence of SRP in Shamouti orange appears to be influenced by soil and climatic factors. Potassium deficit causes bio-membrane dysfunction, which results in water loss, cell necrosis, and collapse, ultimately leading to SRP [86]. If wax and potassium are applied to fruit in the packing house, the postharvest appearance of SRP can be minimized.…”

Citrus fruits are well known for their taste, flavour, aroma and fragrance, with rich vitamin C content. Fruits are rich in various nutrients, minerals and vitamins because of which they have the important role in pharmaceutical and nutraceutical industries. The citrus fruit cultivation experiences many challenges through biotic and abiotic stresses leading to occurrence of pest and diseases coupled with physiological disorders. The occurrence of pre and post-harvest disorders due to abiotic stresses and improper harvesting methods and unhygienic field conditions would lead to reduction in yield, fruit quality and commercial value of the produce and products. Improper harvesting and management in citrus fruits reduce the quality and appearance of the fruits. Pre-harvest disorders like granulation, fruit cracking, puffiness, superficial rind pitting, creasing and sunburn, and post-harvest disorders such as chilling injury, oleocellosis, rind staining, peteca, stylar end breakdown and stem end rind breakdown are the resultant disorders repeatedly noticed in citrus fruits. Maintenance of garden hygiene, flower regulation, water and nutrient management, bahar treatment, use of growth regulators and crop load coupled with canopy management would help in minimising the above disorders in citrus fruit crops.
