“…Although these amendments can improve physical and chemical characteristics of the sandy; yet, their extensive use might have negative potential ecological risks (Zhang et al, 2019), e.g. high emissions of the greenhouse gases which might possess a global warming hazards (Bassouny and Abbas, 2019). Two amendments were selected in this study, i.e.…”

“…On the other hand, no significant variations were detected between these two amendments. Generally, biochar, which is a porous material, has the potentiality to retain soil moisture (Bassouny &de Jusus Duarte et al, 2019) and also restore soil fertility (Novak et al, 2019) because of its high organic carbon content (Song et al, 2019) and plant nutrients in ash (Novak et al, 2019).The results obtained herein agree with those reported by Hailegnaw et al (2019) who found significant changes in soil pH, CEC, and exchangeable Ca 2+ , K + , and Mg 2+ owing to the application of biochar. Likewise, Jien (2019) recorded significant reductions in soil bulk density, penetration resistance, soil losses while increased water retention capacity, aggregation stability and crop production in soils amended with biochar.…”

“…M. ELSHONYet al considering appropriate preparations of composts or biochar from these organic wastes (Abdelhafez et al, 2017). Generally, compost and biochar amendments improve soil, physical and chemical characteristics (Farid et al, 2018;Bassouny and Abbas, 2019;de Jesus Duarte et al, 2019) while reduce the ecological impacts of the residual wastes produced in large amounts annually (Coomes and Miltner, 2016). Unlike compost, the organic carbon in biochar is considered relatively stable (Song et al, 2019)and can persist in soils for several years e.g.…”

“…Organic manures can be used as environmentfriendly sources of plant nutrients (Alshaal et al, 2019;Wakindiki et al, 2019) and improve soil fertility (Uddin et al, 2009). They can retain soil moisture at proper levels and cause up to 30% and increase WUE (Bassouny and Abbas, 2019).…”

Shortage of available water resources has become a critical problem facing vegetable production in Egypt. So, the aim of this study is to decrease the level of irrigation water: 85 and 70% of full irrigation requirements (FI), versus 100% FI in presence of four compost rates (0, 4.8, 9.6 and 14.4 m 3 ha -1 ). Results show that, deficit irrigation levels caused considerable reductions in many growth parameters and the total yield. But we can save 15% of the water used with an average total yield of 39.15 Mgha -1 and a yield shortage of 14.1% in both seasons. This is an acceptable level of decrease in view of the 36.3 Mgha -1 national average according to the 2017 Egypt's Agricultural Statistics. The application of compost at different rates increases the growth, quality and quantity of cauliflower at different water deficiency levels. The highest application rate of compost + 100% of FI recorded the highest values in the characteristics of vegetative growth, total yield and NPK content in curd. The treatment 85% of FI + 14.4 m 3 compost / ha came in the second rank recording significant differences with all other treatments in both seasons. The results also indicate that the water productivity in the case of 85% FI is significantly equal to the water productivity in case of 100% of FI in both seasons. It is; therefore, concluded that compost applications minimized the negative implications of deficient irrigation on cauliflower production.

In this concern, the organic amendments not only enrich soils with nutrients which release upon its decomposition, but also improve the physical, chemical and biological characteristics of the amended soils (Farid et al, 2014;Bassouny and Abbas, 2019). However, the efficiency of these fertilizers seemed to be relatively low when compared with the traditional mineral fertilizers (Yildirim et al, 2011).…”

Increasing consumer awareness has contributed in establishing food safety issues and environmental concerns through introducing organic and bio-approaches as substitutes for the traditionally chemical fertilization. However, the efficiency of these fertilizers seemed to be relatively low when compared with the traditional mineral fertilizers. This study postulates that algae extracts of Chlorella sp. might stimulate the growth of plants. To examine this assumption, a field study was conducted for two successive seasons (2015/2016 and 2016/2017) using different N-sources e.g. organic (compost), bio (Azotobacter chroococcum and Azospirillium lipoferum) and mineral (ammonium nitrate) fertilizers with or without algeal extracts of Chlorella sp. to investigate their efficiency for improving the growth parameters and yield components of broccoli plants grown on a sandy loam soil. Results reveal that the highest increases in uptake of NPK were attained for the application of "compost + ammonium nitrate + biofertilizer". Such improvements resulted in concurrent increases in plant height, number of leaves per plant, leaf area; shoot fresh weight, chlorophyll a and b, curd weight and diameter, vitamin C, TSS, total phenol and antioxidants content in broccoli heads and the outcome head yield. Moreover, the combination between different N-sources and foliar spray of alga extract resulted in further significant increases in NPK uptake by plants and this in turn improved significantly, the abovementioned growth parameters and yield components. Accordingly, our results support the hypothesis indicating that algae extracts improved significantly the growth parameters and yield components of broccoli plants grown on a sandy loam soil.
