Cotton subsurface drip and overhead irrigation efficiency, maturity, yield, and quality
Subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops. This study compared soil water, water use, crop maturity, lint yield, and fiber quality of cotton (Gossypium hirsutum L.) grown with SSD to cotton grown with overhead irrigation. Three experiments were conducted at two Georgia locations in 2004 and 2005. Treatments consisted of overhead irrigated, ...

Assessment of aquacrop, cropsyst, and WOFOST models in the simulation of sunflower growth under different water regimes
This work compares the performance of AquaCrop, a crop simulation model developed by FAO, with that of two well established models, CropSyst and WOFOST, in simulating sunflower (Helianthus annuus L.) growth under different water regimes in a Mediterranean environment. The models differ in the level of complexity describing crop development, in the main growth modules driving the simulation of ...

Ecohydrological modeling of irrigation scheduling of maize using time series analysis in the temperate region of Kashmir valley, India
Water, one of the most crucial inputs of irrigation, should be utilized judiciously to identify appropriate strategies for planning and management of irrigated farmland. The present study was conducted for the crop maize (Zea mays), grown mainly in the rabi-season (July–October), to evaluate the irrigation water requirements in the temperate region of Kashmir Valley, India during the ...

Sprinkler irrigation changes maize canopy microclimate and crop water status, transpiration, and temperature
During a sprinkler irrigation event some water is lost due to wind drift and evaporation (WDEL). After the irrigation event, plant-intercepted water is lost due to evaporation. The water lost causes microclimatic changes which could result in positive or negative plant physiological changes. We studied the microclimatic and physiological changes on two fields grown with maize (Zea mays L.) ...

Irrigation frequency effects on growth and ethanol yield in sweet Sorghum
With the increasing costs of fossil fuels, new methods of generating renewable fuels need to be researched and developed. This study was undertaken to assess the effects of irrigation frequency on crop growth and ethanol yield of sweet sorghum [Sorghum bicolor (L.) Moench]. Nine combinations of pre- and postanthesis irrigation frequencies triggered by 35, 50, or 65% depletion of plant-available ...

Self-Cleaning Irrigation Water Filters
One of the critical components of successful agriculture is irrigation, which ensures that crops receive the water they need to thrive. However, using untreated or impure water for irrigation can have detrimental effects on crops and the environment. Self-cleaning irrigation water filters have emerged as a groundbreaking solution to this problem. The Importance of Self-Cleaning Irrigation Water ...

The effect of rigid scheduling on productivity and water-use of potatoes (Solanum tuberosum L.) grown under small-scale irrigation
This paper evaluates the results of a study highlighting the effect of rigid scheduling on crop water use and soil water extraction patterns, crop coefficients, crop response functions and water-use efficiency (WUE). The cumulative Penman potential evapotranspiration (Etp) at the end of the season reached around 400 mm and the total depth of water applied between planting and harvest through ...

Irrigation and Nutrition
Mike, our Agronomist, was recently asked a few questions about irrigation and nutrition for a magazine. What quality parameters can be influenced (fruit size, flavour, firmness, shelf life, etc.)? All crop quality parameters can be enhanced through correct use of nutrition. Having the ideal strength and balance of nutrients at all stages of the crop cycle will help to ensure the best product ...

Long-term Polyacrylamide formulation effects on soil erosion, water infiltration, and yields of furrow-irrigated crops
Two formulations of water-soluble anionic polyacrylamide (WSPAM) are used in agriculture to reduce erosion and manage infiltration in furrow irrigations, although few if any reports have compared their effectiveness. A control and two WSPAMs, a granular form and the inverse emulsion, or oil-based liquid form, were applied to irrigation water supplied to furrows formed in a silt loam soil with ...

Irrigation scheduling under water shortage: investigation of scion-rootstock of peach and water deficit combinations
Adequate choice of variety, rootstock and irrigation techniques could be, together, sources of improvement of water use. A field experiment was carried out in northern Tunisia on two drip irrigated peach varieties grafted on two rootstocks. Two deficit levels, mild DI1 and severe DI2, were applied. Phenological survey allowed determination of the crop growth stages: initial, development, mid- ...

A decision tool for sustainable agricultural policies: the case of water saving scenarios for Apulia Region (Southern Italy)
The economy of Apulia Region largely depends on agriculture but the scarce water resources are the main factor threatening the sustainable production of this sector. This paper describes a geographical information system (GIS) based water balance tool that integrates maps of crops, climate and soil parameters with various scenarios of cropping pattern and farming practice changes. The aim is ...

Improved Agricultural Irrigation Scheduling Using a Soil Water Content Sensor - Case Study
Abstract The key to scheduling irrigation timing and amounts is determining moisture depletion in the soil. Two common methods include tracking crop evapotranspiration (ETc) and tracking the water content with a sensor buried in the soil. In Colorado, a popular online tool that estimates the ETc for a variety of well-irrigated crops is the Colorado Agricultural Meteorological Network (CoAgMet). ...

Intelligent irrigation controller, the key to agricultural modernization
Background:With the increasing demand for efficient and sustainable agricultural practices, intelligent irrigation controllers have become a key component of modern agricultural management. These systems provide a platform for precision agriculture, enabling farmers to optimize water use, increase crop yields and reduce environmental impact. In this article, we will explore the role of ...

The water we eat
Agriculture imposes a heavy and growing burden on Europe's water resources, threatening water shortages and damage to ecosystems. To achieve sustainable water use, farmers must be given the right price incentives, advice and assistance. Food is intrinsically bound to human wellbeing. Besides the importance of good food for good health and the pleasure we derive from eating, agricultural ...

Soil Water Sensors for Agriculture – Theory and Issues
Soil water sensors have been used for irrigation and water management in agriculture for many years, but with limited success in many cases. Nonetheless, the use of soil water sensors in increasing as water scarcity increases and, conversely, problems associated with over irrigation also increase. Common problems with soil water sensing included sensor failure, problems with wiring, lack of or ...

Simulating yield response of quinoa to water availability with aquacrop
The modeling of yield response to water is expected to play an increasingly important role in the optimization of crop water productivity (WP) in agriculture. During 3 yr (2004–2007), field experiments were conducted to assess the crop response to water stress of quinoa (Chenopodium quinoa Willd.) in the Bolivian Altiplano (4000 masl) under different watering conditions (from rain fed, RF, to ...

Can water use efficiency be modeled well enough to impact crop management?
Crop water use efficiency (WUE, yield per unit of water use) is key for agricultural production with limited water resources. Policymakers and water resource managers working at all scales need to address the multitudinous scenarios in which cropping systems and amounts, timing and methods of irrigation, and fertilizer applications may be changed to improve WUE while meeting yield and harvest ...
