Abstract Sweet corn (Zea mays L.) was irrigated using randomized complete block and line source experimental designs in 1984 and 1985 on a mixed, mesic Cumulic Ultic Haploxeroll soil. Irrigations were scheduled when ≈50% of the available water was depleted in the root zone of the 100% treatment to refill the root zone to 0% to 100% of field capacity (five irrigation levels). Four yield parameters were measured for all plots: yield of all ears before husking, yield of good husked ears, kernel yield (fresh), and total dry matter production of plants and ears. Maximum relative total unhusked ear

Tomato crop is grown worldwide and is considered a mass consumer product. In Ecuador, tomato growers face two major issues: water scarcity and water mismanagement, which cause a reduction in the framers’ gross income and ecosystem services. This paper is aimed at finding an optimal irrigation scheduling in greenhouse tomato crop to achieve a balance among production, fruit quality and water use efficiency. Thus, two experiments were settled. In the first experiment, four water doses (80, 100, 120 and 140% ETc) and two irrigation frequencies (one and two irrigations per day) were compared. The

Irrigation is the supply of water to crops by artificial means. It is designed to permit the desired plant growth in arid regions and to offset drought in semiarid regions or subhumid regions. Even in areas where average seasonal precipitation may seem ample, rains are frequently unevenly distributed, or soils have low water holding capacities so that traditional rain-fed agriculture is a high-risk enterprise. Irrigation provides a means for stable food production. In some areas, irrigation prolongs the effective growing season. With the security provided by irrigation, additional inputs like

This poor management and poor utilization of water have led to a drastic decline in the quality and quantity of available water. In South Africa agriculture uses about 50% of available water.

Cambodia’s economy is based largely on the agricultural sector which contributes 33 percent of the national GDP and employs more than 67 percent of the national labour force. Rice production is central to this sector: not only do the majority of Cambodia’s farmers depend directly and indirectly on the success of the rice crop each year, but being the main food staple, rice production is a significant factor in the national effort to promote food security. Despite its importance, rice farming in Cambodia has traditionally been dependent on rainfall rather than irrigation. Rainfall distribution

In this project we studied optimal use and adoption of sophisticated irrigation technologies. The stated objectives in the original proposal were to develop a conceptual framework for analyzing intra-season timing of water application rates with implications for crop and irrigation technology selection. We proposed to base the analysis on an intra-seasonal, dynamic, agro-economic model of plants' water demand, paying special attention to contamination of groundwater and soil in intensively cultivated areas that increasingly rely on water of lesser quality.

This brief assesses how high-resolution satellite imagery was used in the Lao People’s Democratic Republic to map how irrigation schemes changed agricultural production and improved the livelihoods of smallholder farmers. It analyzes how rice cultivation altered between 2016 and 2020 and explains how ground data and household surveys were used to backup remote sensing information. Highlighting how small irrigation schemes allowed farmers to double-crop their land and boost overall rice production, it shows how spatial analysis can also be used to remotely assess the impact of drought and flood

Since the early 1980s, the Fogera Plain has been one of Ethiopia's major rice production areas. The introduction of rice, its commercialisation and the subsequent increased surplus production has led to the ability of smallholder rice farmers to intensify their production through diverse investments, mainly in supplementary irrigation. This has also enabled rice farmers to diversify crop production, mainly during the off-season, through the production of high-value crops like vegetables. Despite this expansion, a recent visit to the Fogera Plain by the authors revealed that most smallholder ri

This rapid evidence review explores how climate change can create incentives for participating in illicit drug production by disrupting agricultural and natural-resource-based livelihoods and exacerbating social, economic, and political stresses and conflict. However, it is difficult to identify a precise causal relationship between the impacts of climate change and illicit drug production, and the effects of climate change appear to be limited compared with other driving forces. In Afghanistan, climate change is expected to contribute to rising temperatures, worsening water stress, and increa

Standard salinity management theory, derived from blending thermodynamic and semi- empirical considerations leads to an erroneous perception regarding compensative interaction among salinity stress factors. The current approach treats matric and osmotic components of soil water potential separately and then combines their effects to compute overall response. With deficit water a severe yield decrease is expected under high salinity, yet little or no reduction is predicted for excess irrigation, irrespective of salinity level. Similarly, considerations of competition between chloride and nitrat

Using treated wastewater (TWW) for crop irrigation represents an important opportunity for ensuring adequate food production in light of growing freshwater scarcity worldwide. However, the environmentally sustainable approach of using TWW for irrigation can lead to contamination of produce with fecal pathogens that may remain in treated water. The overall goal of this research was to evaluate the correlation between the presence of fecal indicator bacteria (FIB) and that of a suite of human pathogens in TWW, the irrigated soil, and crops.

Soilless crop production in protected cultivation requires optimization of many environmental and plant variables. Variables of the root zone (rhizosphere) have always been difficult to characterize but have been studied extensively. In soilless production the opportunity exists to optimize these variables in relation to crop production. The project objectives were to model the relationship between biomass production and the rhizosphere variables: temperature, dissolved oxygen concentration and water availability by characterizing potential growth and how this translates to actual growth.
