“…2,7 The results showed that the RUE and the biomass of T1 treatment were higher than those of T2 treatment, which was due to the fact that under the limited irrigation conditions, T1 treatment could ensure the water supply after anthesis and reduce the distribution of photosynthetic products to the root system, thus increasing the total above-ground biomass and increasing the RUE. The RUE values in this study ranged from 0.64 to 1.39 g•MJ −1 , which were basically consistent with the previous research report of Ali et al 22 Photosynthesis is the main factor determining the RUE; 2 therefore, increasing the RUE depends on the efficiency of photosynthesis. Many studies have shown that water stress can reduce the photosynthetic rate of leaves, thereby reducing the RUE.…”

BACKGROUND: As a common abiotic stress, water deficit stress has a negative impact on the growth and yield of many field crops worldwide. In this study, a mobile rain shelter experiment was conducted in the 2017-2019 growing seasons to investigate the effects of water stress at different growth stages on various traits in winter wheat, including plant height, leaf area index (LAI), biomass, radiation use efficiency (RUE), leaf photosynthetic traits, and yield. RESULTS: Three different limited irrigation treatments were applied: no irrigation at all stages (T0), no irrigation at the reviving and jointing stages (T1), and no irrigation at the heading and grain-filling stages (T2). In all treatments, 2-year averages showed that T1 resulted in the highest grain yield (6470 kg ha −1 ). The plant height and LAI of winter wheat increased in the order of T0 < T1 < T2. In addition, T1 increased post-anthesis biomass. The net photosynthetic rate and RUE were significantly higher in T1 than in other treatments. T1 could improve leaf photosynthetic traits by increasing Gs, Fv/Fm, ≌PSII, and qP, thus increasing RUE and grain yield.CONCLUSION: We propose that irrigation at the heading and grain-filling stages was the optimal limited irrigation practice for efficient radiation use and high yields in winter wheat in the arid and semi-arid area of northwest China.

Crop efficiencies associated with intercepted radiation, conversion into biomass and allocation to edible organs are essential for yield improvement strategies that would enhance genetic properties to maximize carbon gain without increasing crop inputs. The production of 20 potato landraces—never studied before—was analyzed for radiation interception ( ε i ), conversion ( ε c ) and partitioning ( ε p ) efficiencies. Additionally, other physiological traits related to senescence delay (normalized difference vegetation index (NDVI) s l p ), tuberization precocity ( t u ), photosynthetic performance and dry tuber yield per plant (TY) were also assessed. Vegetation reflectance was remotely acquired and the efficiencies estimated through a process-based model parameterized by a time-series of airborne imageries. The combination of ε i and ε c , closely associated with an early tuber maturity and a NDVI s l p explained 39% of the variability grouping the most productive genotypes. TY was closely correlated to senescence delay (r P e a r s o n = 0.74), indicating the usefulness of remote sensing methods for potato yield diversity characterization. About 89% of TY was explained by the first three principal components, associated mainly to t u , ε c and ε i , respectively. When comparing potato with other major crops, its ε p is very close to the theoretical maximum. These findings suggest that there is room for improving ε i and ε c to enhance potato production.

“…Recycling wastewater for agricultural irrigation is one of the common practices in arid and semiarid regions [79]. Insuffi cient water supply at the grain fi lling stage can lead to early leaf senescence and reduced LAI and grain yield, unless the water defect fi ll up with supplemental irrigation [80]. Irrigation changes widely crop responses to the environment.…”

The arid and semi-arid regions comprise more than forty present of the Earth's land surface on which a large number of people situated and largely engaged in agriculture to meet their basic needs. However, agriculture in these regions are highly infl uenced by several factors including water limitation, extreme heat, frequent drought, bared and marginal soil, vulnerable topography for natural hazards, erosive rain and wind. In order to cope with these challenges a number of essential scientifi c investigation and cultural practices have continuously released, modifi ed and recommended to sustain agriculture production in these regions. Some of these indispensable investigation and practice included that soil and water conservation, rain water harvesting and supplementary irrigation, use of stress tolerant crops and integrating of diverse farming system. So in this review it is attempted to discuss several points concerning arid and semi-arid land agricultural constraints and management action carried out to solve such constraints.
