The experiment was conducted at the research farm of ICAR- Central Coastal Agricultural Research Institute, Goa, India during 2016–2019 to estimate crop water requirement (CWR) pineapple different growth stages and compare performance economic viability irrigation systems. Crop calculated based on consolidated weather data 14 years evapotranspiration (ETc) using Penman-Montieth equation CROPWAT...
Central Rift Valley Lakes sub-basin, Ethiopia. The competition for water is rapidly increasing in lakes sub-basin due to the combined effect of various resources developments. However, impacts recent and future development pathways on balance three interconnected (i.e. Lake Ziway, Langano Abiyata) are unknown. Water Evaluation And Planning (WEAP) model was used assess lakes. We considered that ...
Agriculture is critical for a country’s population growth and economic expansion. In Saudi Arabia (SA), agriculture relies on groundwater, seasonal water, desalinated recycled water due to lack of surface resources, dry environment, scanty rainfall. Estimating consumption plan crop requirements (CWR) in changing environments difficult micro-level data consumption, particularly agricultural syst...
In the coming years, climate change is predicted to impact irrigation water demand considerably, particularly in semi-arid regions. The aim of this research investigate expected adverse impacts on management Saudi Arabia. We focus influence requirements Al Quassim (97,408 ha) region. Different models were used for intermediate emission SSP2-4.5 and high SSP5-8.5 Coupled Model Intercomparison Pr...
Assessing irrigation mitigating drought impacts on crop yields with an integrated modeling framework
Irrigation is one of the major adaptation strategies to combat negative impacts drought on crop yields. However, during droughts, water resources are limited and determining exact irrigation amount its response yields crucial. Existing yield simulation models data-intensive a majority these point-based. Therefore, this study presents novel integrated modeling framework by using two parsimonious...
Investigating the effects of optimized fertilizer and irrigation levels on water use efficiency productivity wheat crop at small farms is great importance for precise sustainable agriculture in Pakistan's irrigated areas. However, traditional farmer practices production are inefficient unsustainable. This study aimed to investigate deficit nitrophos bread grain yield, yield parameters, nutrient...
The El-Kharga Oasis in the Western Desert of Egypt is selected as study area due to its hyberarid climate condition and water scarcity. In this region, fossil groundwater main source; therefore, preserving quality quantity mandatory. This evaluated suitability for irrigation purposes assessed requirements cultivated crops optimize supply hyperarid regions. total, 79 deep samples were hydrochemi...
Coastal Bangladesh experiences significant poverty and hazards today and is highly vulnerable to climate and environmental change over the coming decades. Coastal stakeholders are demanding information to assist in the decision making processes, including simulation models to explore how different interventions, under different plausible future socio-economic and environmental scenarios, could ...
چکیده استان کرمان از مناطق خشک و نیمه خشک کشور ایران است که آب محدودکننده ترین عامل توسعه کشاورزی آن می باشد. از میان شهرستان های استان، شهرستان بافت که یکی از قطب-های کشاورزی به شمار می رود، انتخاب شده است. به منظور استفاده بهینه ی آب در کشت محصولات زراعی شهرستان بافت به بررسی تبخیر– تعرق، کارآیی مصرف آب نسبی، عملکرد نسبی و مقایسه الگوهای بهینه کشت در راندمان های متفاوت آبیاری پرداخته شد. در ...
