Drought and crop yield

Plant Biology, Journal Year: 2021, Volume and Issue: 23(6), P. 881 - 893

Published: Aug. 15, 2021

Abstract Episodes of water shortage occur in most agricultural regions the world. Their durations and intensities increase, their seasonal timing alters with changing climate. During ontogenic cycle crop plants, each development stage, such as seed germination, seedling establishment, vegetative root shoot growth, flowering, pollination fruit development, is specifically sensitive to dehydration. Desiccation threatens yield leads specific patterns, depending on type plant harvested parts, e.g . leafy vegetables, tubers, tap roots or fruits. This review summarizes effects drought stress plants relates dehydration‐dependent penalty organ tissue. The control transpiration reorganization architecture are core importance for maintaining proper relationships. Upon dehydration, provision partitioning assimilates uptake distribution nutrients define remaining growth activity. Domestication crops by selection high under input has restricted genetic repertoire achieving tolerance. Introgression suitable alleles from wild relatives into commercial cultivars might improve ability grow less water. Future research activities should focus more field studies order generate realistic improvements crops. Robotic phenotyping be integrated mapping identification relevant traits.

ABSTRACT Shallow groundwater in many cities around the world is subject to elevated temperatures that pose a risk quality and ecosystems. The objective of this study assess suitability different trend estimation methods for temperature specifically investigate spatio‐temporal long‐term changes water urban Vienna. Twenty‐year data records (2001–2020) from sources were used air, soil, river regarding their annual mean extreme percentile values. effects quality, methods, various time periods analysis investigated. Block bootstrapping combination with Mann–Kendall test was found be suitable method determining significance trends if time‐series are short (10 years), as underlying assumptions lowest among all approaches. Between 2001 2020, average Vienna increased by 0.9 K/decade shallow 0.8 air. However, increase not linear has intensified later decade an 1.4 K/decade. temperatures, represented lower (cold) / upper (warm) 10th soil quantile regression, show strongest air temperatures. For groundwater, these value site‐specific influenced infrastructure interaction water. These results underline importance spatially temporally high‐resolution highlight need aquifer characterisation sustainable use geothermal energy heating cooling.

Impact of climate change-induced warming on groundwater temperatures and quality

Applied Water Science, Journal Year: 2023, Volume and Issue: 13(12)

Published: Nov. 14, 2023

Abstract The impacts of climate change-induced warming on our ecosystems can no longer be neglected, but understanding consequences for groundwater in general and quality particular is alarmingly incomplete. In this review, we therefore provide an overview the current state knowledge related to impact global precious resources. Groundwater shallow aquifers closely associated with increasing average land surface temperatures has already reached + 1 K compared pe-industrial times. Until end twenty-first century, temperature increases local up 10 are possible. Monitoring data, laboratory field experiments all evidence that such sufficient substantially modify through numerous interlinked biogeochemical processes, which have summarized a conceptual overview. Warming highly site-specific spatially heterogeneous, complicates their assessment prediction. Locally, unconfined nutrient-rich floodplain most susceptible warming-induced changes. Importantly, processes affecting water not only modified by long-term rise temperatures, also short-term during weather extremes, great relevance riverbank filtration. At regional scale, cold regions impacted permafrost thawing especially vulnerable warming. As majority temperature-sensitive or very slowly reversable, pressingly require comprehensive mechanistic before it too late develop suitable countermeasures management strategies.

Development and the Effect of Weather and Mineral Fertilization on Grain Yield and Stability of Winter Wheat following Alfalfa—Analysis of Long-Term Field Trial

Plants, Journal Year: 2023, Volume and Issue: 12(6), P. 1392 - 1392

Published: March 21, 2023

Within the framework of a long-term experiment, established in 1955, we evaluated development and effects weather mineral fertilization (Control, NPK1, NPK2, NPK3, NPK4) on yield stability winter wheat following alfalfa. In total, 19 seasons were analysed. The changed considerably at experimental site. Significant increases minimal, mean, maximal temperatures dated to period 1987-1988, while precipitation remained same this day (insignificantly increasing trend by 0.5 mm per annum). Rising November, May, July positively affected grain yield, especially treatments with higher N doses. No relationship between was recorded. Highest inter-annual variability recorded Control NPK4 treatments. Although minerally fertilized provided slightly yields, difference NPK insignificant. According linear-plateau response model, recommended dose 44 kg ha-1 corresponds 7.4 t ha-1, provides an average 6.8 ha-1. application doses did not lead significant increase. Alfalfa as preceding crop reduces need contributes sustainable conventional agriculture, however, its share rotations is decreasing both Czech Republic Europe.

Abstract Meeting the rising energy demands of cities is a global challenge. Exploitation additional heat in subsurface associated with urban island (SUHI) has been proposed to address heating demands. For sustainable use this it crucial understand how SUHIs evolve.

In this paper, a sequence (1979-2022) of long-term trial established in Lukavec 1956 (Czech Republic) focusing on the effect weather, various nitrogen (N) fertilization methods (control, PK, N1PK, N2PK, and N3PK) preceding crops (cereals, legumes, oil plants) winter wheat grain yield is presented. The weather significantly changed at site trial. While trend mean temperature increased, precipitation did not change over long term. Four relationships between were evaluated to be significant: (a) February (r = -0.4) (b) -0.4), (c) March (d) May 0.5). trends for all fertilizer treatments including unfertilized control. N3PK treatment provided highest yields, while control had lowest yields. Comparing crops, yields harvested when followed legumes. On other hand, cereals as least suitable crop terms yield. According linear-plateau model, optimal dose modern varieties, following legumes under trial's soil climate conditions, was 131 kg ha-1 N, corresponding 8.2 t ha-1.
