According to rice planting system in China, rice can be divided into early-season rice (ESR), mid-season rice and single-cropping late rice (MRSLR), and double-season late rice (DSLR). According to the actual growth period of ESR, MRSLR and DSLR, we calculated 36 climatic factors which may influence the distribution of climatically suitable areas and we employed MaxEnt model for prediction the climatically suitable areas of ESR, MRSLR and DSLR in historical period (2001–2020) and future periods (2041–2060 and 2081–2100). The key climatic factors for ESR are minimum air temperature of July, precipitation of driest month, precipitation of growth period and average air temperature of March; for MRSLR, the key climatic factors are minimum air temperature of coldest month, minimum air temperature of July and precipitation of wettest month; for DSLR, the key climatic factors are minimum air temperature of June, maximum air temperature of October and minimum air temperature of July. For ESR and DSLR, climatically suitable areas expand northwestward, with almost no climatically unsuitable areas. For MRSLR, climatically suitable areas expand northeastward, but climatically unsuitable areas appear in Guangxi, Guangdong, and Taiwan. The influence of climate change on the climatically suitable areas of rice in China exhibits significant regional differences, the unsuitable areas of rice are transforming into suitable areas. Attention should be focused on new suitable areas and new unsuitable areas. This study offers important scientific insights for the effective management and cultivation of rice.</p>","PeriodicalId":54947,"journal":{"name":"International Journal of Plant Production","volume":"2 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transition towards the long-term adoption of conservation agriculture (CA) technologies can possibility overcomes these constraints and making it a crucial component of modern farming systems. Therefore, the effects of conservation tillage and residue retention on wheat cultivation were evaluated from 2015–2016 to 2019–2020 under RWCS on CA fields maintained for twenty one years. Five tillage treatments viz., zero tillage without residue retention (ZT-R), zero tillage with residue retention (ZT+R), permanent bed planting without residue retention (PBP-R), rotary tillage without residue retention (RT-R) and conventional tillage without residue retention (CT-R) were evaluated in four times replicated randomised complete block design. The CT-R recorded 28%, 25%, 24%, and 16% higher energy inputs than those of the ZT+R, ZT-R, PRB-R, and RT-R, respectively. Nevertheless, the lowest grain energy output was recorded in RT-R (86,769 MJ ha⁻¹) and CT-R (86,926 MJ ha⁻¹). Under CT-R, greenhouse gas (GHG) emissions were approximately 20%, 19%, 17%, and 10% greater than those under ZT-R, ZT+R, PRB-R, and RT-R, respectively. Compared to ZT-R, ZT+R, PRB-R, and RT-R plots, CT-R exhibited significantly lower carbon efficiency ratio and carbon sustainability index. The long-term study revealed that ZT+R represent a promising step towards sustainability, characterized by low global warming potential and high energy use efficiency. This makes it an appealing agricultural technique for wheat production in the sub-tropical IGP regions under irrigated RWCS.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":54947,"journal":{"name":"International Journal of Plant Production","volume":"45 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted during the 2021-22 and 2022-23 growing seasons to investigate the effects of seed pre-treatment (priming) and phosphorus doses on plant growth, yield attributes, and seed chemical composition in lentil at Siirt, Türkiye. Six seed priming treatments and four phosphorus doses were used in the study. The research was laid out in split-plot randomized complete block design with four replications. According to the results, phosphorus fertilizer increased seed yield, but there was no statistical difference between 15 and 60 kg P₂O₅ ha^− 1. Seed priming had a synergistic effect, allowing for higher seed yield when combined with phosphorus fertilizer, especially silicon priming resulting in high seed yield even at low phosphorus fertilizer doses. This result also indicated that seed priming improved phosphorus efficiency. The highest seed yield and net income were obtained by 6 kg P₂O₅ ha^− 1 with silicon priming treatment. Moreover, seed priming with salicylic acid, beneficial bacteria and silicon boosted growth and yield attributes, and seed chemical composition. Silicon priming increased the total antioxidant content in seeds while salicylic acid priming provided opportunities for both the increase of total antioxidants and phenolics.

Focusing on ‘Jingmai 17’, a hybrid variety, and ‘Jimai 22’, a conventional type, across three planting densities (150, 300, and 450 plants·m⁻²) during the 2021–2023 growing seasons, the investigation centered on key agronomic metrics such as leaf area per culm (LAC), SPAD values for chlorophyll content, dry matter, nitrogen accumulation and remobilization, alongside grain yield and its components. The results highlight ‘Jingmai 17’’s superior performance over ‘Jimai 22’, notably in maintaining a larger LAC post-anthesis, a slower decline in SPAD values during grain filling, and an extended green leaf area duration. These characteristics are conducive to higher biomass accumulation and efficient post-anthesis remobilization. Importantly, a planting density of 300 plants·m⁻² emerged as optimal, enhancing canopy structure for maximal light interception and promoting a higher nitrogen use efficiency (NUE) and yield for both varieties. The NUE of Jingmai 17 and Jimai 22 in both years increased by 2.2%, 0.4% and 1.7%, 1.4%, respectively, relative to the 450 plants·m⁻² treatment; and the yield increased by 10%, 4%, 9%, 4%, and 10%, 5%, 8%, 2%, relative to the 150 plants·m⁻² and 450 plants·m⁻² treatments, respectively. This optimal density represents a strategic balance, enabling robust wheat growth while maximizing resource use efficiency. For the eastern Huang-Huai-Hai region, these findings suggest a potent strategy to augment wheat yields and improve agricultural sustainability. Adopting a planting density of 300 plants·m⁻² could significantly enhance the productivity of hybrid winter wheat varieties, tapping into their heterosis advantages for substantial yield improvements.

However, the extent to which crop production might be improved and how this would impact future water and land requirements remains poorly understood. We analyzed potential improvements in the production of these crops and quantified their future water and land requirements under different scenarios. Potential improvements were detected through percentile analysis in three remote sensing-derived performance indicators for each crop in the Nile Delta’s Zankalon region: (i) crop yield, (ii) crop water productivity, and (iii) transpiration fraction (transpiration to actual evapotranspiration, T/AET). We applied detected improvementsto construct plausible scenarios for Egypt’s water and land requirements to sustain domestic crop production until 2050. Our findings indicate limited potential to improve T/AET (&lt; 4%). However, improvements of up to 27% for crop yields and up to 14% for water productivity are possible.
