FIELD experiments were conducted during winter seasons of 2016/2017 and, 2017/2018 at Qalyub, Qaluobia Governorate, Egypt. The main objective of this study to find out the efficacy of several biological and chemical treatments on controlling onion white rot disease caused by Sclerotium cepivorum as well as on the growth and productivity of onion plants. Three biological treatments including control (water application), Trichoderma asperellum (85 g/100 L-1), Pseudomonas fluorescence (500 ml/100 L-1), were applied respectively. These treatments were combined with five chemical treatments (commercial fungicides) and applied as follows: Control, Iprodione (250 g/100 L-1), Tebuconazole with Fluopyram (50 ml/100 L-1), Tebuconazole (188 ml/100 L-1), Azoxystrobin plus Mefenoxam (200 ml/100 L1). The ability for growing onion crop productivity was tested and decrease disease severity and incidence growth of white rot by the treatments were sprayed three times on plants at (40-55-70) days after planting or (19-41 BBCH) stages by using knapsack sprayer by (300 L./Fed). Results indicated that combination dipping onion seedling by T. asperellum significantly gave the highest indications of total and the marketable yield in comparison to P. fluorescence for both seasons. Moreover, the three times of spray by Iprodione applications combined with T. asperellum was increased onion crop productivity in comparison to the control treatment significantly, and the disease was lowered, disease severity, and increasing the control efficiency in both seasons. Whereas, the three times of spray by Tebuconazole applications had a moderate effect on onion crop productivity or the disease severity and incidence of Sclerotium cepivorum in comparison to the control treatment despite low to medium recovery following applications. Finally, the non-treated control treatment was the lowest of crop productivity and control of disease efficacy of onion crop.

Generally, strawberry plants are cultivated under open field conditions and low-tunnels in commercial farms as a high profit yield (Karlsson and Werner, 2011, Demchak and Hanson, 2013). The price of strawberry in the early season is expensive while the shelf life of strawberry fruits is short. Special procedures, managements and transactions are highly required for profitability producing strawberry commercially. Producing strawberry under urban conditions as a selfproduction will reduce the yield waste while neglect the unmarketable yield. The contribution of urban horticulture for producing strawberry as well as leafy vegetables create more resilience city for climate change negitive impacts.

Pressures to sustain modern agricultural systems may agronomic quality caused progressive degradation of soil structure and depletion of soil fertility level as a result of organic matter reduction (Masciandaro et al. 1997). Orange production is of a great socio-economic interest in the world, in which soils with very low organic matter content are prevalent. These soils need organic matter application to improve and maintain their agronomic quality. The use of organic manure as a source of organic matter is a common practice to improve soil conditions. Organic matter improves soil physical properties such as water retention capacity, reducing the volume of water needed for irrigation (Entry et al. 1997) and soil enzymatic activity (Salam et al. 1999), as well as increases soil nutrients (Bellamy et al., 1995, Barker 1997 and Abdelaal et al., 2013).

Two field trials were carried out during the two consecutive seasons,of 2014/2015 and 2015/2016, at the Experimental Farm of Arid Land Agricultural graduate studies and Research Institute (ALARI), Faculty of Agriculture, Ain Shams University in Shubra el-Khaimah, Qalyubiah Governorate. The aim of the current investigation was to study the impact of three planting dates (18-Dec, 7-Jan and 27-Jan), three irrigation levels at 60, 80 and 100% of irrigation water requirements (IR) and their interaction on potato crop productivity. 9 treatments were obtained by combination of different planting dates and irrigation levels. Planting dates were arranged as the main plots, while, irrigation levels were arranged in the sub plots, The obtained results indicated that the highest tuber yield was obtained by the first planting date (18 Dec.) during both studied seasons, While, The highest plant growth parameters and tuber yield per plant were obtained by 100% followed by 80% irrigation level during both seasons. However, the interaction effectindicated that first planting date (18-Dec) combined with 100 % irrigation level gave the highest potato tuber productivity than the other treatments, whereas the interaction of first planting date )18-Dec) combined with 80% irrigation level gave the best for water use efficiency compared to the other treatments during both tested seasons.

Mushrooms are great food for humans having valuable nutritional composition but low energy content (Gyenge et al., 2016). Mushroom production is an environmental-friendly technology; nevertheless, large volumes of solid waste are generated after harvesting, called mushroom spent substrate, (MSS) (Pecchia et al., 2014) or mushroom compost (MC). It also called mushroom bran or mushroom residue in China which is one among the mushroom biggest producers in the world (Chang, 2006). Sample et al. (2001) and Medina et al. (2012) reported that about 5 kg of waste substrates are produced from the production of 1 kg of mushrooms which may adversely affect the environment if they not appropriately controlled. For the progress of the mushroom industry, it is necessary to manage these by-products sustainably.
蘑菇是人类的好食物，营养成分有价值，但能量含量低(Gyenge等人，2016)。蘑菇生产是一项环保技术;然而，收获后会产生大量固体废物，称为蘑菇废基质(MSS) (Pecchia et al.， 2014)或蘑菇堆肥(MC)。在中国，它也被称为蘑菇糠或蘑菇渣，是世界上最大的蘑菇生产国之一(Chang, 2006)。Sample等人(2001年)和Medina等人(2012年)报告称，生产1公斤蘑菇会产生约5公斤的废弃基质，如果控制不当，可能会对环境产生不利影响。为了蘑菇产业的发展，有必要对这些副产品进行可持续的管理。

Citrus fruits are the biggest area cultivated or production in addition to fruit exportation also it is considered the most popular fruit crop in Egypt. Valencia orange grown in sandy soils, which usually poor in nutrient content, organic matter and low water holding capacity, with high nutrient leaching losses resulting in negative effects on vegetative growth, yield and fruit quality. Trees grown in such soils, therefore need more attention in cultural practices such as fertilization, foliar spray with minerals and bio fertilizers to enhance growth, yield and fruit quality Salama, 2015.

Plant height, number of leaves/plant, average leaf area, and herb fresh and dry weights/ plant greatly improved with the applied treatments especially with IAA treatments followed by GA3 treatments. However, the number of lateral branches/plant and stem diameter were increased with BA treatments especially with 10 ppm than 5 ppm. Generally, the second cut was superior in the studied vegetative growth parameters than the first cut. The highest values of N, P, K, Fe, and Mn were recorded with BA at 10 ppm, whereas higher Zn values were recorded with BA at 5 ppm. Active ingredients including total phenols, total flavones, total chlorophyll, and Lascorbic acid greatly increased with IAA at 50 or 100 than the other treatments or the control. However, volatile oil percentage and volatile oil content/plant were high in IAA at 50 or 100 ppm followed by GA3 at 200 ppm. The second cut was superior to the first cut in promoting volatile oil percentage and volatile oil content/ plant in both studied seasons. The main components in volatile oil were 1,8-cineole, linalool, á-trans-bergamotene, germacrene D and á-muurolol. The highest values of linalool, the main component in the volatile oil of sweet basil (50.90%) was recorded by IAA at 100 ppm.
