This study was carried out during the winter seasons of 2016 and 2017 at private farm in Beni Suief Governorate, Egypt to investigate the integrative use of potassium levels (24, 48, 72 and 96 kg K₂O fed⁻¹) and soil mulching (rice straw and bare soil) on growth and productivity of garlic under three levels of surface irrigation (60, 80 and 100 % of crop evapotranspiration (ETC)). The experimental layout was a spit-spilt plot system based on Randomized Complete Blocks Design. Irrigation levels, potassium rates and mulch types were randomly allocated in the main, sub and sub-sub plots, orderly. The obtained results showed that, the amount of irrigation at 80 and/or 100 % ETC was accompanied increases by plant height, leaves number, leaf area and dry weight plant⁻¹, total bulbs yield, individual bulb weight, cloves weight and number bulb-1 compared to irrigation 60 % ETC. The application of potassium from 24 to 48 and further to 72 and 96 kg K₂O fed⁻¹ gave gradual increments in the aforementioned growth and productivity of traits. The rice straw mulch augmented all previous growth, total bulbs yield and its components compared to bare soil. Generally, the 1st order interaction between irrigation percent at 100 and/or 80 % ETC × potassium rate at 96 and/or 72 kg K2O fed⁻¹, irrigation percent at 80 and/or 100 % ETC × rice straw, potassium rate at 96 kg K2O fed⁻¹ × rice straw and the 2nd interaction of irrigation percent at 100 % ETC × potassium rate at 96 kg K₂O fed-1 × rice straw mulch had pronounced effects on morphological characters and bulbs yield and its components compared to other combined treatments.

Agricultural wastes cause a serious environmental problem in Egypt. Utilization of these wastes by an environmentally friendly way is a very important issue. The objective of this study was to utilize rice straw into high-value products. Antioxidant activity, total soluble phenols, and flavonoids were evaluated in ethyl acetate extract prepared from rice straw after alkaline hydrolysis. Total phenols were found to be 221.6 mg gallic acid equivalents (GAE), while total flavonoids were 4.9 mg rutin equivalents (RE). The extract exhibited strong antioxidant activity measured by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method and its IC₅₀ value was 0.4 mg/ml. Furthermore, the ethyl acetate extract possessed high antioxidant activity assayed by β-carotene bleaching method and its value of lipid peroxidation inhibition (LPI) was 75.4%. It also exhibited high reducing power and its IC₅₀ value was equal to 0.06 mg/ml. HPLC analysis indicated that this extract contained seven phenolic acids including; protocatechuic, caffeic, syringic, p-coumaric, ferulic, rosmarinic and cinnamic, in addition to two flavonoids; qurecetin and kaempferol. Results indicated that ferulic and p-coumaric acids were the major soluble phenolic acids in rice straw, and their concentrations were 3.9 and 2.9 mg/g DW. It can be summarized that the strong antioxidant activity of ethyl acetate extract, prepared from rice straw, was highly correlated with its high level of phenolic compounds.
