Particularly, in Chile, the last decade has been marked by a mega-drought period, which has severely impacted agriculture. In this scenario, common bean (<i>Phaseolus vulgaris</i> L.) has been seriously affected due to its dependence on irrigation. In this work, we studied how 'Zorzal,' the most sown cultivar in Chile copes with drought stress and the mechanisms used to deal with it. A greenhouse experiment was performed during the 2019–2020 growing season. Plants were subjected to a severe drought stress suspending irrigation at the pre-flowering stage. Photosynthetic parameters, chlorophyll concentration, relative leaf water content (RWC) and lipid peroxidation were analyzed at 7 and 21 days after water suspension, yield was analyzed at the end of the growing season, and those parameters were compared to a susceptible cultivar of the same gene pool ‘Arroz Tuscola.’ ‘Zorzal’ stood out for having diverse treats associated with drought tolerance, as maintaining stable RWC during drought stress, a better reactive oxygen species scavenging system than ‘Arroz Tuscola,’ and stable root biomass during the drought condition. However, seed production was significantly reduced. Our results evidence that ‘Zorzal,’ the most widely cultivated cultivar of common bean in Chile, has good physiological and anatomical treats for plant survivance under drought stress conditions. However, our study suggests that these characteristics may not be enough to maintain a stable seed production.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 1","pages":"41 - 52"},"PeriodicalIF":1.4,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138594865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted in two main maize-producing regions of Eswatini, the Highveld at Mankayane and Middleveld at Luve.

Biochar-based controlled-release N fertilizers (BCRNFs) are a new concept to address the N loss problem and increase yield. In this research, different BCRNFs were developed by impregnating ammonium sulphate (AS) into biochar (BC) and mixing with bentonite (Be), biosolid (BS), rice starch (RS), and bioasphalt (BA) in a different ratio to formulate three new BCRNFs— S1: 40% AS + 55% BC + 5% RS; S2: 50% AS + 15% BC + 15% BS + 20% RS; and S3: 15% AS + 30% BC + 10% Be + 45% BA.

Considering the relationship between water consumption and the amount of energy consumed, the evaluation of water productivity (WP) and energy productivity (EP) seems essential to develop a suitable method for efficient use of water for agriculture in the arid regions with limited water resources. Therefore, in this study, it was attempted to investigate WP and EP, some nutritional traits and stress indices for silage maize and silage sorghum in a loamy sandy soil using a drip tape irrigation system. For this purpose, a field experiment was performed using a randomized complete block split-plot design with three replications under three irrigation levels of I1: 100% (conventional), I2: 80%, and I3: 60% of the crop evapotranspiration (ETc), and four cultivars of sorghum and maize were planted as the main and split plots. The irrigation scheduling was done using a reference crop evapotranspiration (ETo) calculator (Penman–Monteith equation) and AquaCrop simulation model. The results showed that the amount of irrigation water had a significant effect on fodder and dry yield, WP and EP (<i>p</i> &lt; 0.01). The values of fresh and dry yields and WP for silage maize were 61.23 tons/ha, 18.91 tons/ha and 10.73 kg/m<sup>3</sup>, respectively.

The maximum WP and EP for sorghum and maize were obtained in I3 and I1 treatments, respectively. It was also found that the nutritional traits, including dry matter (DM) and crude protein (CP), were affected by crop type (sorghum and maize) and deficit irrigation levels. Hence, the maximum DM (31.72%) and CP (9.607%) were observed for Speedfeed sorghum cultivar under I1 irrigation level, the maximum ash (9.86) was reported for Speedfeed sorghum cultivar under I3 irrigation level, the maximum neutral detergent fiber (NDF) (74.47%) was obtained for Maxima maize cultivar under I1 irrigation level, and the maximum acid detergent fiber (ADF) (39.183%) was achieved for Pegah sorghum cultivar under I1 irrigation level.

However, the DSSAT model performed better than the APSIM model in modeling rainfed rice crop growth and yield (<i>r</i><sup>2</sup> &gt; 0.86 and greater ME). Bias-corrected RCM (HadGEM3-RA) have been linked to the DSSAT model to analyze yield changes of three popular rice varieties (Swarna, Lalat, and MTU 1010) for future climate scenario (2030s &amp; 2040s). The average decrease in rice yield of Swarna is projected to be around 7% in 2030s and 9% in 2040s, and under RCP 8.5, average decrease in rice yield of Swarna is projected to be 12.8% (2030s) and 15.4% (2040s), which is much higher than production of Lalat and MTU 1010 in both the cases. In conclusion, DSSAT might be a helpful tool for determining the effects of management techniques and climate change on various rice varieties.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 1","pages":"85 - 95"},"PeriodicalIF":1.4,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41402882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A study was conducted using 13 parental genotypes (3 male sterile lines and 10 testers) of African marigold to develop 30 F<sub>1</sub> hybrids, and the true hybrids we evaluated based on phenotypic and marker-based genotypic data. Analysis of variance revealed significant diversity among the parental lines for different growth and flower traits. Fourteen SSR markers were used to test the purity of selected F<sub>1s</sub>, out of which two markers (TE57, T93B) showed polymorphism in the parental lines and cross combinations, with 2–5 alleles. The markers, TE57 and T93B revealed polymorphism information content (PIC) of 0.345 and 0.543 (mean 0.444), respectively, and detected a heterozygosity mean value of 0.528 in all, indicating the efficacy of microsatellite markers in discriminating the hybrids. The phenotypic data revealed significant difference in means for both quantitative and qualitative traits between the parents and the hybrids, in support of the molecular outcomes pertaining that hybrids detected through microsatellite markers were pure F<sub>1s</sub>. The study identified a set of compatible cross combinations that can be used to develop highly heterotic hybrid combinations with different growth and flowering characteristics.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 1","pages":"1 - 9"},"PeriodicalIF":1.4,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48755018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
