Effect of Drought Stress on Potato Production: A Review

Agronomy, Journal Year: 2022, Volume and Issue: 12(3), P. 635 - 635

Published: March 4, 2022

Potato is the third most consumed crop globally after rice and wheat. It a short-duration crop, versatile in use, suitable for growing wide range of environments, its production increasing rapidly. The modern potato considered drought-sensitive it susceptible to yield loss because drought stress. Unfortunately, severity, frequency, extent have been around globe climate change. susceptibility has primarily attributed shallow root system. However, several studies past decades suggested that also depends upon type, developmental stage, morphology genotype, duration severity They overlooked, depth only significant cause susceptibility. This review combines these understand varying response genotypes. explores current scenario effect degrees stress on potatoes’ growth, development, yield. In absence drought-tolerant genotypes, agronomic practices should be improved mitigate Late maturing cultivars, nutrient management, mulching, foliar application plant growth regulators can used during prolonged droughts. Irrigation at tuber initiation bulking stage early droughts reduce adverse effects drought.

Green-blue water accounting in a soil water balance

Advances in Water Resources, Journal Year: 2019, Volume and Issue: 129, P. 112 - 117

Published: May 17, 2019

It has become common practice to speak about ‘green’ versus ‘blue’ water consumption, in order distinguish between consumption of rainwater groundwater or surface water. The two sources differ terms possibilities for storage and use. Whereas industrial, municipal livestock supply primarily depend on blue water, crop cultivation relies both green Discriminating a field is not straightforward: refers evapotranspiration (ET) contained the harvested crop, which appear undifferentiated form. One cannot see part ET plant originates from irrigation In this paper I propose generic physically based method differentiate evaporation (E) transpiration (T) by daily accounting fractions each soil vegetation layer. all fluxes leaving layer day average that during day. This allows an accurate assessment efficiency (the ratio applied), precise estimation footprints production either yield).

Advancing the Water Footprint into an Instrument to Support Achieving the SDGs – Recommendations from the “Water as a Global Resources” Research Initiative (GRoW)

Water Resources Management, Journal Year: 2021, Volume and Issue: 35(4), P. 1291 - 1298

Published: March 1, 2021

Abstract The water footprint has developed into a widely-used concept to examine use and resulting local impacts caused during agricultural industrial production. Building on recent advancements in the concept, it can be an effective steering instrument support, inter alia, achieving sustainable development goals (SDGs) - SDG 6 particular. Within research program “Water as Global Resource” (GRoW), initiative of Federal Ministry for Education Research, number projects currently apply enhance order identify areas where is being used inefficiently implement practical optimization measures (see imprint more information). With this paper, we aim raise awareness potential inform decision-making public private sectors towards improved management SDGs.

Published: Aug. 22, 2023

Around 90% of fresh renewable water is being used in Iran, indicating high stress conditions across the country. Given that agricultural irrigation accounts for majority use and consumption, any efforts to alleviate must focus on enhancing management. This paper aims exhaustively compile existing literature consequences drivers insecurity, discuss strategies balancing food security context Severe scarcity can be largely attributed governance gaps Iran. In addition, inefficient use, population growth, warming/drying trends recent half a century are other major causes scarcity. Groundwater over-depletion, quality deterioration aquatic resources, decreased environmental flows habitat destruction, conflicts significant improper management Several productivity conservation interventions, drawn from rich literature, were suggested improve Furthermore, some water-food-energy nexus optimization methods, including changing cropping patterns, modifying energy tariffs, manipulating diet, reducing waste, discussed. Nexus-based strategies, which aim achieve balance between production sustainability, importance consumption sector. While there has been improving nexus-based measures, it essential policy-makers prioritize dimensions effectively address its words, system prerequisite adopting strategy aimed at coping with security.
