The objectives of this study were to comparison between tow different available household wastes and investigate affect the volume of biogas production. Determine the most appropriate mixing ratio between waste and water and also determine the appropriate filling ratio for the fermenter. Microbiological evaluation of fermented wastes mixture were d...

The objective of this research study was to investigate the effect of inlet water temperature on drip irrigation system uniformity. The experimental work was held under laboratory conditions, whereas a model for a drip irrigation system was used to follow the effect of increased irrigation water temperature on uniformity parameters. The variables o...

This study aimed to get the most possible benefit of using deficit irrigation to maximize water productivity of squash, besides investigating the ability of drip irrigation uniformity to reduce the expected negative effect of deficit irrigation on squash crop yield production (Cucurbita pepo-Hybrid Revera). Three levels of irrigation uniformity (UL...

Indoor fish ponds are an economic activity that helps to apply the needs of fish meat which also have the advantage of being conducted on many scales. The main objective of this study is to make evaluation of using micro-sprinkler as an alternate for traditional nozzle sprayer aerators to obtain advantages of ease of implementation and save energy...

Proper exploitation of biogas is key to recovering energy from bio waste in the framework of a circular economy and environmental sustainability of the energy sector. This study aimed to design and manufacture an engineering unit for biogas purification. Experiments were carried out through the year of 2021 at Agricultural Engineering Department, F...

This study aimed to integrate the ability of organic mulching (rice straw) and subsurface irrigation with deficit irrigation to save soil moisture content (SMC) and increase water use efficiency (WUE). A field experiment was carried out during 2019 on tomato crop in sandy soil. The variables included four levels of irrigation namely 70, 80, 90, and...

Potato is described as a sensitive crop to short periods of irrigation deficit and Nitrogen deficiency. Farmers usually use excessive amounts of irrigation water and fertilizers to obtain higher yields. A field experiment was undertaken to assess the effects of irrigation regime and Nitrogen fertilization on potato tuber yield, Chlorophyll content...

A field experiment was conducted with the purpose of testing and evaluating the use of a closed-loop, real-time control system which was developed by (Elnemr M.K., 2017) for application to a poor hydraulic performance drip irrigation system with sandy loam soil cultivated with cucumber crop. This control system collects soil moisture data through t...

A prototype of a real-time closed loop automatic control system has been successfully developed to suit trickle irrigation systems management. The control system was designed to manage the irrigation system based on collecting data through soil moisture sensors located at three different locations acting each third of the lateral to put the effect...

Moisture sensing devices are considered the main element to reach better irrigation management especially for irrigation systems that are based on automatic control. Moisture devices' location accuracy may affect the accuracy of their sent data which will lead to poor performance under various operating conditions and consequently, affect irrigatio...

Sustainable agriculture is economically, environmentally, and technically viable. Sustainable agriculture has different practices than traditional. Policies should be designed and planned to serve the goals of sustainable agriculture. Policies have to consider the local Egyptian environment and properties. There is a need for a framework lead to cr...

Sustainable agriculture is the practices that use the resources or inputs in a way that may not affect the opportunities of coming generations to get beneficial use of these resources in the agricultural process. The gap between people needs of agricultural products and available resources in Egypt is getting wider. Sustainable agriculture can be r...

Twenty One guava probiotic dairy beverages (Lactobacillus aciophilus LA-5 "2% vol/vol" "T1", Bifidobacterium bavidium "2% vol/vol" "T2" and Lactobacillus aciophilus LA-5 "1% vol/vol" and this ratio in Bifidobacterium bavidium "T3") were produced using 0, 20, 35, 50, 65, 80 and 100% (vol/vol) (unsalted whey) which is a product of Ras cheese manufact...

Accurate calculation of irrigation water requirement, affects directly the crop production, water use efficiency (WUE), and energy use efficiency (EUE). Two methods for calculating irrigation water requirement were compared under two types of emitters (R and T). The first method was based on the Moisture Allowed Depletion (MAD) while the second bas...

Uniformity of water application in drip irrigation system is one of the key criteria that affects crop production and economic operation of the system. Using emitters that introduce a poor emission uniformity (EU), may turn into a must in case of lack of financial resources because of its expected low prices. A field experiment has been taken place...

Fisheries are required to grant convenient environmental conditions for fish growth with minimum cost afford. Providing these environmental conditions should essentially correlate fish type, pond dimensions, water properties, and weather conditions to the fish growth rate, feeding and metabolism. The large uncertainty margin of such parameters rela...

Abstract- Sustainable management of drip irrigation system aims to the efficient use of different input resources like energy, water, and financial resources. This study was achieved to investigate the effect of the drip irrigation system emission uniformity (EU) on the water and energy use efficiencies besides studying its impact on crop profitabi...

A properly designed decision support system (DSS) is an interactive software-based system intended to help decision makers compile useful information from different sources to identify and solve problems and make decisions. A Microsoft Excel 2007 spreadsheet was designed as a DSS to manage fish ponds mechanical aeration process based on the farm av...

A field experiment has taken place in Wahet El-Nagah farm, Khatatba village, Menoufia governorate, Egypt in the year 2005, in order to use the ability of rice-straw mulching as cheap farm residue, to reduce the effect of deficit irrigation on highly sensitive crop for water deficit. Split plot design consisted of soil surface covering case (rice st...

It is very important to have a fast utility for the irrigation system evaluation to help the system designer and operator to evaluate the system performance and make the reactions towards any system operation problem if exists. Microsoft excel 2010 spreadsheet was successfully created in order to evaluate the drip irrigation system hydraulic perfor...

In this study under clay soil conditions during two seasons 2008 and 2009, built in emitter type was used to irrigate pepper crop with 96 h irrigation interval. In order to increase the benefits of water and energy units using water depletion strategy, three amounts of applied water 80, 90, and 100% of gross irrigation requirements (IRg) were studi...

A field experiment was carried out in Al-Shahwan farms, Khatatba village, Sadat city, Menoufia governorate under sandy soil conditions with cucumber crop (F1-Faris). Uniformity parameters including emission uniformity, uniformity coefficient, distribution uniformity, manufacturing coefficient of variation, and emitter flow rate variation were measu...
