“…Superior performing genotypes in DS, Rupali (0.261 g/L), Genesis 836 (0.258 g/L) and PBA Seamer (0.222 g/L) showed the highest values for WUE_GY. These estimates were comparatively lower to those reported by Pang, Turner, Du, et al 2017 in chickpea for WUE_ GY (DS = 0.44-0.14 g/L; WW = 1.06-0.81 g/L) under controlled and those revealed for both WUE_B and WUE_GY under field conditions (Zhang et al 2000;Anwar, McKenzie, and Hill 2003;Amiri et al 2021). These differences could be due to the varied experimental conditions, moisture availability and the potential of the genetic material (Angadi et al 2003;Bramley, Turner, and Siddique 2013).…”

“…In contrast, PBA Seamer had the highest UFPN and was among the top-yielding genotypes. Previous research on chickpeas (Zhang et al 2000;Amiri et al 2021) and other field crops (Hatfield and Dold 2019;Yang et al 2021;Erbacher et al 2022) has shown that plants in DS environments regulate WUE by controlling water loss and CO 2 diffusion through stomata. They achieve this by employing a variety of strategies to conserve energy and resources and by optimising various physiological processes (Bramley, Turner, and Siddique 2013;Blessing et al 2018).…”

Chickpeas are well adapted to rainfed conditions, but a lack of moisture during the reproductive phase can result in lower pod setting and ultimately reduced grain yield. The exact reasons for this reduction are not fully understood, partly because of the lack of information on soil moisture content (SMC) and water use during podding. This study aimed to address this knowledge gap by quantifying the impact of gradual drought on various yield components of desi‐type genotypes using the fraction of transpirable soil water (FTSW) method. Two water treatments were applied at the start of anthesis: well‐watered (WW) and drought‐stressed (DS). The WW was maintained at 24% SMC, whereas the DS was dried to 3% SMC. The results showed that DS caused early podding (3.3 days less), with reductions in plant height (11.4 cm), leaf area (1249.5 cm2), flowers (18.6), pods (27.4), seeds (37.0), grain yield (0.2 g), aboveground dry biomass (11.4 g) and harvest index (0.2 g), while increasing flower abortion (14.6) and seed biomass (1.5 g). However, diverse genotypic responses were observed to treatments, as well as water usage, FTSW and SMC that triggered pods which ranged from 1.12 to 1.89 L, 0.05 to 0.43 and 4.0% to 12.2%, respectively. A positive association between days taken and the amount of water used to terminate pods indicated that quicker‐triggering genotypes, such as Rupali and Genesis 836, consumed less water to develop pods than Flipper, ICCV_06109 and PBA Slasher did. Conversely, the negative association between the amount of water used and the number of pods triggered, seeds and grain yield explained the superior performance of Rupali and Genesis 836. These genotypes extracted less water (FTSW = 0.36 and 0.43; SMC = 10.3% and 12.2%, respectively) to develop pods and maintained favourable photosynthesis at lower transpiration rates for longer periods, allowing them to use residual moisture more efficiently. Our research offers crucial insights that can be beneficial to breeders and physiologists, paving the way for future studies aimed at developing drought‐tolerant genotypes.

“…Harvest index (HI) was calculated as the ratio between GY and BY, and seed m −2 (GN) was calculated by dividing GY and GW; the number of pods per plant was also determined (pods/plant). Water use efficiency for yield (WUE) was calculated according to the following formula: GY/WU [36]; in addition, agricultural water productivity (AWP) was calculated as the ratio between GY and the sum of I + P [37,38]. Seed protein concentration (PC) was determined by near-infrared spectroscopy (Foss Infratec 1241).…”

Water Use Efficiency, Spectral Phenotyping and Protein Composition of Two Chickpea Genotypes Grown in Mediterranean Environments under Different Water and Nitrogen Supply

Chickpea is a drought-tolerant crop and an important source of protein, relevant to its beneficial effects. The aim of this study was to assess the response to agronomic management, including water and nitrogen supply, of crop physiological and agronomic traits in relation to water use efficiency and grain protein composition. Two varieties, Pascià and Sultano, were grown at two different sites in South Italy under rainfed and irrigated conditions, with and without starter nitrogen fertilization. Crop physiological assessment was carried out by hyperspectral phenotyping at flowering and during grain filling. Increases in grain yield and grain size in relation to water supply were observed for water use up to about 400 mm. Water use efficiency increased under starter nitrogen fertilization, and Pascià showed the highest values (4.8 kg mm−1). The highest correlations of the vegetation indexes with the agronomic traits were observed in the later growth stage, especially for the optimized soil-adjusted vegetation index (OSAVI); furthermore, grain filling rate showed a strong relationship with photochemical reflectance index (PRI). Experimental factors mainly influenced protein composition rather than protein content. In particular, the 7s vicilin protein fraction showed a negative correlation with grain yield and water use, while lectin showed an opposite response. Both fractions are of interest for consumer’s health because of their allergenic and antinutritional properties, respectively. Data from spectral phenotyping will be useful for digital farming applications, in order to assess crop physiological status in modern agricultural systems.

“…In the face of issues such as imbalanced grain supply and demand with the restricted trade and transportation, China's government has ensured national food security by increasing grain yields [14][15][16], safeguarding food consumption [17], expanding grain storage [18][19][20], and enhancing grain trade [21,22]. As a basis for national stability [23,24], this yield is positively influenced by various underlying driving factors, such as farmland quality [25,26], agricultural mechanization input [27,28], fertilizer and pesticide use [29,30], agricultural subsidies [31,32], and urbanization [33,34]. However, abnormal weather conditions such as droughts, floods, and hailstorms can bring many negative effects [35][36][37].…”

The exploration of the spatiotemporal variations and influencing factors of grain yield in major grain-producing regions is greatly important to maintain stable and sustainable agriculture. Taking Henan Province and Heilongjiang Province as examples, this study reveals the spatiotemporal characteristics of grain yield at the county level by using multisource data on the economy, society, and natural geography from 2000 to 2021 and employing methods such as coefficients of variation, standard deviational ellipses, and spatial autocorrelation analysis. Moreover, geographical detector and geographically weighted regression models are combined to explore the differences in significant influencing factors between these provinces and the spatial heterogeneity of regression coefficients, respectively. The following findings are drawn: (1) Grain yield in both provinces gradually increased, with notable differences in the annual growth rate, the proportion, and at the county level. (2) The number of high-yield counties significantly increased and their spatial distribution became more concentrated, indicating a notable shift in the main regions. (3) The overall spatial correlation of grain yield steadily increased, and the local spatial correlation transitioned from random distribution to gradual aggregation. (4) There were significant differences in the influencing factors, where geographical environment, socio-economic factors, and input factors all affected both provinces. In summary, this study provides a scientific reference for governments worldwide to formulate rational and effective food production policies, thereby contributing to global food security and sustainable social development.
